Embodiment 1

[0018] like figure 1 , a treatment system that is conducive to improving the biodegradability of sewage, including a pretreatment tank and an aeration tank and a sedimentation tank connected to the rear end of the pretreatment, the aeration tank and the sedimentation tank are two, and the aeration tank Including an aeration tank A and an aeration tank B, the sedimentation tank includes a sedimentation tank A and a sedimentation tank B, the aeration tank A is connected to the sedimentation tank A in sequence, and the aeration tank B is connected to the sedimentation tank B in sequence, The aeration tank A is connected to the rear end of the pretreatment tank, and the aeration tank B is connected to the rear end of the sedimentation tank A; the bottom surfaces of the sedimentation tank A and the sedimentation tank B are both conical surfaces or circular concave surfaces.

[0019] Specifically, the settling tank is used for the removal of large-volume insoluble matter or sandy an...

Embodiment 2

[0021] The present embodiment is further limited on the basis of embodiment 1, as figure 1 , in order to facilitate the removal of surface floating and suspended matter, it also includes a grid machine set in the pretreatment pool.

[0022] In order to benefit the sedimentation effect of the A sedimentation tank and the B sedimentation tank, it also includes a flocculant adding device whose outlet is located in the A sedimentation tank and the B sedimentation tank.

[0023] As an easy-to-implement flocculant adding device with good effect, the flocculant adding device includes a flocculant tank and a stirrer located in the flocculant tank.

[0024] As a flocculant adding device that is easy to realize and has good effect, the flocculant adding device includes a clean water pump and a flocculant adding pipe arranged on the water outlet pipe of the clean water pump.

[0025] In order to facilitate the addition of commonly used flocculant powder, the flocculant addition pipe is ...

Abstract

The invention discloses a treatment system facilitating the improvement of the biodegradability of sewage, which comprises a pretreatment tank, aeration tanks and settling tanks, wherein the aeration tanks and the settling tanks are connected with the rear end of the pretreatment tank, the numbers of the aeration tanks and the settling tanks are respectively two, the aeration tanks include an aeration tank A and an aeration tank B, the settling tanks include a settling tank A and a settling tank B, the aeration tank A is sequentially connected with the settling tank A, the aeration tank B is sequentially connected with the settling tank B, the aeration tank A is connected with the rear end of the pretreatment tank, and the aeration tank B is connected with the rear end of the settling tank A; and the bottom surfaces of the settling tank A and the settling tank B are respectively a conical surface or circular concave surface. The treatment system disclosed by the invention is simple in structure, and facilitates the improvement of the proportion of nitrifying bacteria in activated sludge, the improvement of the biodegradability of sewage and the improvement of the efficiency of sewage treatment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a treatment system which is beneficial to improving the biodegradability of sewage. Background technique [0002] At present, water resources are one of the problems that countries all over the world are facing urgently. According to the research report of the United Nations World Resources Institute, the world's water resources are facing a more severe situation than other resources and in the past in terms of quality and quantity. According to statistics, the annual industrial water consumption in the world is trillions of m3, and the situation of this phenomenon is very different in different parts of the world. The demand is extremely incompatible with the limited available water resources, and the industrial and domestic wastewater discharged to natural water bodies in the world every year is also Hundreds of billions of m3, causing more than 35% of fresh water resources to ...
