Embodiment 1

[0033] Such as figure 1 As shown: this embodiment provides a sewage treatment system 100, including reaction pool I1, reaction pool II2, reaction pool III3 and reaction pool IV4 connected in sequence, the reaction pool I1 is provided with a water inlet 21, and the sewage flows by itself after pretreatment Or the pump is extracted to the water inlet 21, the partition plate 7 between the reaction pool I1 and the reaction pool II2 can be disassembled, the reaction pool II2 and the reaction pool IV4 are connected through the connecting pipeline 15, the reaction pool I1 is an anoxic pool, and the reaction pool Ⅱ2 is anoxic pool or aerobic pool, reaction pool Ⅲ3 is anoxic pool or aerobic pool, and reaction pool Ⅳ4 is an aerobic pool. Reaction pool Ⅱ2, reaction pool Ⅲ3, and reaction pool Ⅳ4 are equipped with biological filler 8. Filler 8 is used to hang biofilm, aerobic activated sludge is set in the aerobic tank, anaerobic granular activated sludge is set in the anoxic tank, and nit...

Embodiment 2

[0047] This embodiment provides a sewage treatment method using the sewage treatment system 100 of Embodiment 1, including the following three operating modes:

[0048] Such as figure 2 As shown, the high emission standard AO-AO mode: reaction pool Ⅰ1 and reaction pool Ⅲ3 are anoxic pools, reaction pool Ⅱ2 and reaction pool Ⅳ4 are aerobic pools, and the first fan 11, the second fan 12 and the third fan 13 are turned on , the perforated pipe 9 in the reaction tank I1 is opened, the aerator 10 in the reaction tank II2 is opened, the perforated pipe 9 is closed, the perforated pipe 9 in the reaction tank III3 is opened, the aerator 10 is closed, and the aeration in the reaction tank IV4 The device 10 is opened and the perforated pipe 9 is closed, which is used for areas with poor water quality and high water output standards;

[0049] Such as image 3 As shown, the low emission standard AO mode: remove the partition plate 7 between the reaction pool Ⅰ1 and the reaction pool Ⅱ2...

Abstract

The invention discloses a sewage treatment system and a sewage treatment method, and relates to the technical field of sewage treatment. The sewage treatment system comprises a reaction tank I, a reaction tank II, a reaction tank III, a reaction tank IV, a secondary sedimentation tank and a phosphorous removal tank, which are sequentially arranged, the reaction tank I is provided with a water inlet, the phosphorous removal tank is provided with a water outlet, a partition plate between the reaction tank I and the reaction tank II is detachable, the reaction tank II and the reaction tank IV are communicated through a connecting pipeline, the reaction tank I is an anoxic tank, the reaction tank II and the reaction tank III are both anoxic tanks or aerobic tanks, the reaction tank IV is an aerobic tank, biological fillers are arranged in the reaction tank II, the reaction tank III and the reaction tank IV, aerobic activated sludge is arranged in the aerobic tank, and anaerobic granular activated sludge is arranged in the anoxic tank. The AO process and the AO-AO process can be realized in the process flow, the requirements of different drainage standards are met, the condition that the actual treatment water quantity is lower than the designed water quantity is met, and the dual purposes of adjusting the treatment method, saving energy and reducing consumption are realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and a sewage treatment method. Background technique [0002] The domestic sewage treatment integrated device adopts different processes, but they are all different combinations of the treatment technologies of each unit. Among many treatment processes, biological treatment, anaerobic treatment, biofilm treatment and primary enhanced treatment are widely used, but they all have high operating costs, high labor dependence, and difficulty in adapting to water quality such as complex components of domestic sewage and irregular drainage. Conditions where the water volume fluctuates greatly. [0003] Therefore, it is necessary to provide a sewage treatment system that is adaptable and adjustable for the characteristics of sewage discharge water quality and large fluctuations in water volume, so as to solve the above problems.
