Embodiment 1

[0026] An embodiment of the present invention provides a circulating multiple biochemical sewage treatment device, which includes a cavity. This embodiment has a rectangular cavity structure, and all sewage treatment processes are completed in the cavity. Such as figure 1 As shown, the inner cavity of the chamber is provided with a partition plate 21, and the chamber body is divided into a reaction zone 1 and a precipitation zone 2 by the partition plate 21, and an aerator communicated with the air inlet pipe 63 is provided in the reaction zone 10 11. The inlet pipe 63 is provided with a sixth electromagnetic valve 56, which can control the on-off of the pipeline. The bottom of the chamber is provided with a water inlet pipe 61. After the sewage enters the chamber through the water inlet pipe 61, the anaerobic phosphorus release, aerobic nitrification and anoxic denitrification processes can be completed in the reaction zone 1. After the above-mentioned process is completed, ...

Embodiment 2

[0041] This embodiment is basically the same as the first embodiment, except that the filter area 3 of this embodiment is set outside the cavity, and the rest of the structure and connection and relationship with each area in the cavity are the same as the first embodiment. With this structure, the filter area 3 can be disconnected and connected with the cavity according to the needs. First, it can facilitate the processing, installation and maintenance of the entire device; second, it can facilitate the movement and transportation of the entire sewage treatment device; third, it can be used according to It is necessary to change the size of the cylinder in the filter area 3 to adapt to different qualities of sewage, and it is also convenient to replace or add materials to the filter material 31, making the treatment of the whole device easier.

Abstract

The invention provides a loop multi-biochemical and filtration linked treatment method and a device, a cavity body of a reactor is divided into a reaction zone and a sedimentation zone, wherein, the reaction zone is sequentially divided into an aerobic zone, an anoxic zone and an anaerobic zone from top to bottom, an aerator is arranged in the aerobic zone, a water inlet is arranged at the bottompart of the anaerobic zone, liquid in the reactor generates the loop current through the density difference which is formed by aeration in the aerobic zone; at the same time, a filtration zone is arranged in or out of the reactor, communicated with the sedimentation zone by an overflow pipe and positioned below the sedimentation zone; the filtration process and the backwashing process of the filtration zone can be controlled according to the change of water level of the sedimentation zone through a liquid level travel switch and a controller which are arranged at the upper end of the sedimentation zone. The treatment method and the device fully utilize vertical spatial structure and can realize the loop multi-circulating biochemical linked treatment for removing nitrogen, removing phosphorus and degrading organic matters of sewage; furthermore, the treatment method and the device are characterized by automatic backwashing, power-free sludge reflux, less investment, small and compact device, small occupying area and convenient operation and management.

Description

technical field [0001] The invention belongs to the field of sewage purification and treatment, and in particular relates to a method and device for realizing multiple biochemical and filtration linkage treatment of sewage circulation by setting different functional areas in a cavity. Background technique [0002] With the continuous development of modern society, the construction of industrialization and urbanization has been continuously improved, which has also brought about the increasingly serious water pollution and air pollution. In recent years, the discharge rate of urban domestic sewage in my country has also increased year by year. Due to such a huge sewage pressure, sewage treatment plants in various places have been overloaded for a long time, and even untreated sewage is often directly discharged into rivers and lakes, forming a vicious cycle. Therefore, how to reduce the floor area, improve the treatment effect, and realize the purification treatment of sewage...
