For example, in this embodiment, the treatment facility includes 5 baffle 21, 5 baffle 21 will 6 biological treatment chamber 2 is separated into to the inner chamber, and 6 biological treatment chamber 2 is as being provided with the anaerobe anaerobism treatment chamber of packing, being provided with the oxygen deficiency treatment chamber of oxygen deficiency fungus packing, being provided with the aerobic treatment chamber of aerobic fungus packing, sedimentation tank, biological aerated filter and dephosphorization treatment filtering pond respectively. The specific treatment process comprises the following steps: in the anaerobic treatment chamber, long-chain organic matters in the sewage are decomposed into short-chain organic matters; further decomposing organic matters and filtering nitrogen elements through the anoxic treatment of the anoxic treatment chamber and the aerobic treatment of the aerobic treatment chamber; carrying out sludge-water separation by sedimentation in a sedimentation tank, and then further filtering a water body in an aeration biological filter tank; and finally, removing phosphorus by dephosphorization treatment to remove organic matters, nitrogen elements and phosphorus elements in the sewage, and the residual water body can not cause environmental pollution after being discharged.

Furthermore, reinforcing ribs 3 are respectively arranged on the opposite surfaces of the inner plate body 11 and the outer plate body 13, and the reinforcing ribs 3 extend towards the foaming layer 12 positioned in the middle.

Specifically, the shell of box 1 is thinner after pouring into water in the box 1, can extrude the shell and lead to warping, use strengthening rib 3 can promote the intensity of shell avoids water pressure to lead to warping too big to the compressive strength and the bending strength of 1 overall structure of box have been improved.

Furthermore, the strengthening rib 3 sets up the baffle 21 with the hookup location of box 1 corresponds the department, has strengthened the baffle 21 with connection between the box 1 can consolidate each biological treatment chamber 2, avoids extrudeing biological treatment chamber 2 and brings the damage.

Furthermore, the plate bodies 11 and 13 are provided with beads 111 recessed toward the foam layer to reinforce the strength of the plate bodies 11 and 13.

Further, the reinforcing bar 3 includes a first connector 151, two second connectors 153, and two third connectors 154, wherein: the first connecting piece 151 is provided with a concave part 152 matched with the corrugated rib 111; first ends of the two second connecting members 153 are vertically connected to two ends of the first connecting member 151, respectively; first ends of the two third connecting members 154 are vertically connected to the second connecting members 153, respectively, and the other ends of the third connecting members 154 horizontally extend along the foam layer 12, respectively.

Specifically, the concave portion 152 is configured to be in contact with the bead 111, thereby enhancing the supporting strength. The area formed by the two second connecting members 153 and the first connecting member 151 is aligned and compressed with the PE heat insulating member after the foaming material is filled in the manufacturing process, and the foaming material is extruded between the two second connecting members 153, so that the material is filled and no hole is formed. Because the reinforcing ribs 3 are generally made of metal, the position of the reinforcing ribs 3 needs to be filled and compacted with a foaming material, so that the problem of poor heat insulation effect caused by holes is avoided. The two third connectors 154 are respectively extruded by the foaming materials at the two sides to prevent the reinforcing ribs 3 from being displaced.

Further, the first connecting member 151 of the reinforcing rib 3 is welded and fixed to the corrugated rib. Specifically, the concave portion 152 is buckled on the corresponding wave rib 111 and fixed by welding.

Furthermore, a gap is formed between the two internally and externally opposite reinforcing ribs 3 on the two plate bodies 11 and 13, so that a heat bridge formed by the reinforcing ribs 3 made of metal is avoided.

Further, a heat insulating member 14 is provided in the gap between the inner and outer opposing reinforcing ribs 3, and the heat insulating member 14 is interposed between the third connecting members 154 of the corresponding two reinforcing ribs 3.

Specifically, the two opposite inner and outer reinforcing ribs 3 are separated by the heat insulation piece 14, so that metal contact is avoided, and a heat bridge is guaranteed. The heat insulation member 14 may be made of Polyethylene (PE), and specifically, a PE wood pillow may be used.

In this embodiment, the method for manufacturing the housing specifically includes:

plate processing: the method comprises the following steps of (1) pre-processing and uncoiling a plate, trimming the plate (flattening the length and width directions of the plate and ensuring diagonal lines of the plate) by using a plate shearing machine, and processing the plate by using a special profiling mold, namely processing the plate by professional equipment, profiling and profiling to improve the integral strength of the plate;

plate body preparation: and welding the profiled plate by using an automatic welding process to respectively form two plate bodies for forming the inner wall and the outer wall of the box body, and fixing the reinforcing rib formed by using the roller die and the corrugated rib of the two plate bodies by spot welding.

And (3) foaming preparation: two plate bodies forming the inner wall and the outer wall of the box body 1 are fixed on foaming platform equipment, and preparation is started according to any one of the heat insulation material manufacturing methods described in embodiments 1-3. The polyisocyanate and the combined polyether are chemically reacted under the action of a catalyst to form polyurethane, and simultaneously, a large amount of heat is released. The cyclopentane is used as the foaming agent of the composite polyether to continuously vaporize and enable the polyurethane to continuously expand and fill the inner wall and the outer wall of the box body, so that the shell of the box body 1 is formed.
