Specific embodiment

Below in conjunction with specific embodiment, bactericidal unit of the present invention is further illustrated:

As shown in Figure 1, bactericidal unit of the present invention includes sterilization tank 3 and ozone generator 9, pass through inside sterilization tank 3 Partition 16 divides for sterilizing side 4 and return side 5, and the bottom that sterilizing side 4 passes through partition 16 is connected to return side 5, and sterilizing side 4 is equipped with dirt Water inlet, return side 5 are equipped with discharge outlet.

Sterilizing side 4 is from top to bottom divided into sterilizing gas area and sterilized liquid area, and sewage inlet is set to the top in sterilizing gas area Portion side, sewage pipe 1 protrude into the top in sterilizing gas area by sewage inlet and are equipped with multiple outlets of sewer, and sewage is gone out by sewage Mouth enters sterilized liquid area；Ozone generator 9 includes delivery main 10, and delivery main 10 protrudes into the bottom in sterilized liquid area, and Upwardly extend and be equipped with multiple delivery branch pipes 13 arranged side by side, delivery branch pipe 13 is uniformly provided with multiple ventholes from the bottom to top, ozone by Multiple venthole discharges are sterilized with waste water；Ozone uplink in sterilized liquid area, comes into full contact with sewage, does not make with sewage Ozone gathers sterilizing gas area, and ozone concentration sensor 7 is fixedly arranged on sterilizing gas area, detects to ozone concentration, Bactericidal unit can control the occurrence quantity of ozone generator 9 according to the detected value of ozone concentration sensor 7.

Ozone delivery branch pipe is set in sewage by bactericidal unit of the present invention, and ozone is arranged by equally distributed venthole Out, it is sterilized with waste water, ozone gas uplink can come into full contact with the sewage to sterilize in side, increase connecing for ozone and sewage Contacting surface product, improves sewage bactericidal effect.

Partition 16 described in the present embodiment can be made by stainless steel, and plastic plate material also can be used, and to be considered and be sterilized Tank shell is easy connection.Be reserved with sewage routeway between 3 bottom of box of bottom surface and sterilization tank of partition 16, the top surface of partition 16 and Side is tightly connected with the inner sidewall of sterilization tank 3, to guarantee that ozone gas or non-sterilized sewage enter return side.

The present embodiment protrudes into drainage overflow pipe 6 in return side 5 by discharge outlet, the nozzle of drainage overflow pipe 6 upward, and The height of 6 nozzle of drainage overflow pipe is identical as the sterilizing height of 4 liquid level of side.The nozzle height of drainage overflow pipe 6 determines sterilizing The nozzle of drainage overflow pipe 6 upward, and is arranged opposite in return side 5 for the height of sewage level in side 4, therefore, the present embodiment Higher position, it is ensured that the wastewater level in sterilization tank 3, while ensure that sterilization time and sterilization effect.

In the present embodiment, the sewage pipe 1 outside sterilization tank 3 is equipped with flow sensor 2, and the outside of sterilization tank 3 is equipped with Controller 8, flow sensor 3, ozone concentration sensor 7 and ozone generator 9 are electrically connected with controller 8, and controller 8 It according to the detected value of flow sensor 2 and ozone concentration sensor 7, is analyzed, the ozone for adjusting ozone generator in real time occurs Amount is accomplished that ozone amount is not excessive, is not lacked.

The flowmeter with transporting function can be used in flow sensor 2, and signal can be 4-20mA, or RS485.Stream Meter should be installed on the pipeline section of liquid flowing full, can be installed on crook under the U-shaped of pipeline.

The ozone concentration detection device with on-line checking function can be used in ozone concentration sensor 7, and signal can be 4- 20mA, or RS485.Detection device and ozone probe can be directly mounted at the sterilizing side of sterilization unit, can also pacify On the circulating line drawn loaded on sterilizing side, probe is higher than liquid level.

Controller 8 can be integrated chip, and computer and auxiliary software also can be used.Controller 8 will receive flow letter Number and ozone concentration signal, signal can be 4-20mA and is also possible to RS485.By data analytical calculation, to ozone generator 9 Output signal, output signal can be RS485, control ozone occurrence quantity.Ozone occurrence quantity is mainly conveyed with the discharge of sewage, ozone The arrangement spacing of branch pipe 3, the outlet pitch of holes in ozone delivery branch pipe 13, the volume of sterilization tank 3 and the position of drainage overflow pipe 6 It is related to set height.

Delivery main 12 protrudes into cabinet, can be divided into more parallel main pipes, and every main pipe upwardly extends defeated equipped with more Branch pipe 13 is sent, so that ozone comes into full contact with sewage；Meanwhile the venthole of the delivery branch pipe 13 successively becomes from the bottom to top Greatly, and the height of delivery branch pipe 3 is lower than liquid level, to guarantee the power of ozone uplink, and the contact area with sewage.

For contact area and the time of contact for improving sewage and ozone, spray is equipped at the outlet of sewer of sewage pipe 1 Device 15, sewage enter sterilized liquid area through spray equipment 15, come into full contact with ozone.The spacing of sewage outlet can basis Water flow determines, accomplishes still be evenly distributed as much as possible sewage when small water.Meanwhile in the sewage pipe 1 for protruding into sterilizing air side Upstream is equipped with the first non-return valve 14, prevents ozone from inversely entering sewage network through sewage pipe 1.

Similarly, it is equipped with the second non-return valve 12 in the delivery main 10 of ozone generator 9, prevents ozone and counter-current of sewage to smelly Oxygen Generator 9.In order to control ozone generator 9, the second non-return valve 12 upstream be arranged switch valve 11, can be used to open and Ozone output pipe is closed, normal condition is to open, and the maintenance of ozone generator can be carried out after closing.Control valve can be hand It moves, be also possible to motor-driven valve.

The cabinet of sterilization tank 3 described in the present embodiment is made of stainless steel or plastics, to improve anticorrosion effect.Meanwhile The material of sewage pipe 1 can be all kinds of tubing that can be applied in waste pipe network system such as UPVC pipe, cast iron pipe, PE pipe.

As shown in Fig. 2, sewage flows into sterilization tank 3 through sewage pipe 1 when using bactericidal unit of the present invention, control is opened Valve on device 8, flow sensor 2, ozone concentration sensor 7, ozone generator 9 and each pipeline, the real-time root of controller 8 According to the discharge of sewage and ozone concentration signal, the ozone occurrence quantity of ozone generator 9 is controlled, after sewage sufficiently sterilizes in sterilizing side 4, It is discharged into return side 5, and by drainage overflow pipe 6, to realize the abundant sterilizing to sewage.

The above be not for limiting the present invention, anyone skilled in the art do not depart from spirit of the invention and In range, possible variation and modification can be made, therefore protection scope of the present invention should be with the claims in the present invention institute Subject to the range defined.
