In order to achieve the purpose, the invention provides the following technical scheme: a sponge municipal sewage treatment system comprises a sedimentation tank, wherein one side of the sedimentation tank is connected with an overflow tank through a first connecting pipe, the bottom of the overflow tank is connected with a grid tank through a second connecting pipe, a thick grid and a thin grid are vertically arranged in the grid tank, and the distance from the thick grid to the second connecting pipe is shorter than the distance from the thin grid to the second connecting pipe; one side of the grating pool is connected with a purifying chamber through a third connecting pipe; the bottom of the purifying chamber is connected with a water storage chamber through a fourth connecting pipe; the purification chamber is arranged under the sedimentation tank, the grid tank is arranged under the overflow tank, and the water storage chamber is arranged at the bottom of the grid tank and the purification chamber; a lifting pump is arranged at the top of the overflow tank, the output end of the lifting pump is connected with a lifting pipe, an annular pipe is arranged at the bottom end of the lifting pipe, a limiting rod is inserted into the annular pipe, the top end of the limiting rod is fixedly connected to the inner wall of the top of the purification chamber, and the outer side of the annular pipe is fixedly connected with a buoyancy ring; one side of the sedimentation tank, which is far away from the first connecting pipe, is connected with a water inlet pipeline; when the sewage treatment system works, the sedimentation tank, the overflow tank, the grid tank, the purification chamber and the water storage chamber of the existing sewage treatment system are sequentially arranged on the ground, no overlapped part exists in the vertical direction, the water storage chamber occupies larger space, and meanwhile, in order to reduce the occupation of larger land area of the water storage chamber, the depth of the water storage chamber is larger, when the water in the water storage chamber is pumped by a lifting pump for final treatment before use, particularly water at the bottommost part, if the water pumping end of a lifting pipe is arranged at the bottommost part of the water storage chamber, the required lifting power is larger, and the energy consumption is increased, so the invention mainly solves the problems of how to reduce the occupation of the land area and reducing the energy consumption when the water in the water storage chamber is lifted; the specifically adopted measures and working processes are as follows: in the vertical direction, the water storage chamber is arranged at the bottommost layer, the grid pond and the purification chamber are arranged at the second layer of the top of the water storage chamber, the sedimentation tank and the overflow tank are arranged at the uppermost layer, three layers of arrangement of the sedimentation tank, the overflow tank, the grid pond, the purification chamber and the water storage chamber is realized, the occupied area is small, the treated water sequentially passes through the sedimentation tank, the overflow tank, the grid pond and the purification chamber through the self gravity and finally reaches the water storage chamber, and the energy consumption problem caused by transferring the water treated in the previous process to the next process through external work is further reduced; after the lifting pump is started, when the lifting pump extracts and utilizes water in the water storage chamber through the lifting pipe, the annular pipe at the end part of the lifting pipe can move up and down on the limiting rod, and the buoyancy ring connected to the outer side of the annular pipe can always float on the water surface; after the lift pipe extracts water, the buoyancy ring drives the annular pipe to slowly descend on the limiting rod, the water pumping point during water pumping is ensured to gradually descend under the condition that water can be pumped, and compared with the condition that water is directly pumped up from the bottommost part of the water storage chamber, the buoyancy ring overcomes the defect that the work done by gravity is less, and the energy consumption is reduced.
Preferably, the bottom of the limiting rod is inserted with an inverted T-shaped rod, the water storage chamber is T-shaped, the bottom of the inner side of the water storage chamber is fixedly connected with a plurality of elastic pieces, the tops of the elastic pieces are fixedly connected with an auxiliary box, and two sides of the auxiliary box are in contact with the narrow part of the side wall of the water storage chamber; when the water in the water storage chamber passes through the water storage chamber at the lifting part of the lifting pipe, even if the buoyancy ring drives the end part of the lifting pipe to gradually move downwards, the end part of the lifting pipe finally moves to the bottommost part of the water storage chamber to extract the bottommost water, and the acting power of the lifting pump needs to be large enough, so that the bottommost water needs to be lifted for a certain distance before being extracted to the bottommost part; when the elevator pump work is with the water extraction, the water level in the water storage chamber descends gradually, when reducing the top of auxiliary tank, the elastic component of compressed promotes the auxiliary tank and rises, the auxiliary tank promotes the water of water storage chamber bottom and rises, the T pole top of falling is promoted to rise and inserts the inside part of gag lever post and increase, when drawing water gradually, the buoyancy circle finally drives the elevator pipe end and removes to the inboard bottommost of auxiliary tank, accomplish the extraction to all water in the water storage chamber, because the bottommost of auxiliary tank is promoted by the elastic component and by the certain distance that rises of the bottommost of water storage chamber, consequently when the water extraction to the bottommost, the work of overcoming gravity is few, the further consumption of the energy has been reduced.
Preferably, the part of the inverted T-shaped rod, which is positioned outside the limiting rod, is sleeved with an elastic sleeve, and the elastic sleeve is contacted with the inner wall of the annular tube; after the water in the water storage chamber is completely taken out, namely the water in the auxiliary tank is completely taken out, the elastic ring drives the ring pipe to be positioned on the T-shaped rod at the bottommost part of the limiting rod, when the purified water in the purification chamber enters the water storage chamber, the water in the auxiliary tank is impacted by the falling water flow in the water flow falling process, the water in the auxiliary tank generates large ripples, the generated ripples can enable the ring pipe to move on the water surface, the ring pipe collides with the T-shaped rod, the damage of the T-shaped rod or the ring pipe is caused, the elastic sleeve is sleeved on the T-shaped rod, the elastic sleeve is made of a water-resistant elastic material, when the ring pipe is pushed by the generated large ripples to collide with the T-shaped rod, the damage of the T-shaped rod or the ring pipe can be prevented due to the protection of the elastic sleeve, and the service lives of the T-shaped rod and the ring pipe are prolonged.
Preferably, the top of the inner wall of the annular tube is in a bell mouth shape, and the diameter of the inner wall of the annular tube is gradually reduced from top to bottom; in order to prevent that the annular tube from taking place the ascending removal of horizontal direction on the gag lever post, consequently the internal diameter of annular tube is the same with the diameter of gag lever post surface, simultaneously again because the diameter of falling T pole is thinner, consequently rise at the water level, when the annular tube moves on the gag lever post again under the drive of buoyancy circle, annular tube inner wall top is the horn mouth form, and the diameter of annular tube inner wall reduces from top to bottom gradually, can make things convenient for the annular tube to aim at the gag lever post, make the buoyancy circle rise the top of gag lever post smoothly, prevent that the annular tube card from in the gag lever post bottom.
Preferably, the position of the outer side of the limiting rod, which is positioned at the top end of the limiting rod, is fixedly connected with a blocking disc, and the top of the annular pipe is fixedly connected with a vertical rod; when the annular pipe rises along the limiting rod, the vertical rod at the top of the annular pipe does not rise after contacting the blocking disc, so that the lifting pipe between the blocking disc and the annular pipe has a certain space, and the lifting pipe is prevented from being extruded after the annular pipe contacts the blocking disc, so that the lifting pipe is bent at the annular pipe, the damage of the lifting pipe is caused, and the service life of the lifting pipe is prolonged.
Preferably, the top end of the vertical rod is made of an elastic material, and the top end of the vertical rod is provided with a plurality of through holes; when the vertical pole top strikes the barrier disc, because the vertical pole top is made by elastic material, consequently when the vertical pole strikes the barrier disc, can have certain cushioning effect, when having ripple to produce simultaneously, the ring pipe drives vertical pole has certain reciprocating, make vertical pole top strike the barrier disc many times, cause the softer part of vertical pole top to take place more times and warp, arouse permanent deformation, consequently a plurality of thru holes have been seted up at vertical pole top, can get into the water after some production ripples in the through-hole of seting, can extrude water when vertical pole top warp, consume partly energy, reduce the extrusion on vertical pole top, and then the probability that permanent deformation takes place at vertical pole top has been reduced.
