Embodiment Construction

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0025] Such as figure 1 As shown, a sewage treatment system includes a sewage tank 1, an agitator 2, a neutralizer 3, a biochemical tank 4 and a sedimentation tank 5, the sewage tank 1 and the agitator 2 are communicated through a sewage pipe 6, and the sewage pipe 6 is provided with The sewage lifting pump 7, the sewage lifting pump 7 pumps the sewage in the sewage pool 1 into the agitator 2 through the sewage pipe 6; the output end of the agitator 2 communicates with the input end of the neutralizer 3 through the sewage reconciliation pipe 8, neutralizes The input end of the device 3 is also communicated with the lime milk pipe 9 that introduces lime milk; the output end of the neutralizer 3 is communicated with t...

Abstract

The invention relates to a sewage treatment system, which comprises a sewage pool, a stirrer, a neutralizer, a biochemical pool and a precipitation pool, wherein the sewage pool and the stirrer are communicated through a sewage pipe; a sewage lifting pump is arranged on the sewage pipe and pumps sewage in the sewage pool into the stirrer through the sewage pipe; the output end of the stirrer communicates with the input end of the neutralizer through a sewage conditioning pipe; the input end of the neutralizer also communicates with a lime milk pipe for introducing lime milk; the output end of the neutralizer communicates with the biochemical pool through a neutralized sewage pipe; the output end of the biochemical pool communicates with the bottom of the precipitation pool through a pipeline; the output end of the precipitation pool communicates with the input end of a clean water pump through the pipeline; the output end of the clean water pump communicates with a stirrer through a backflow pipe. Compared with the prior art, the sewage treatment system has the advantages that the over-concentration sewage is diluted and conditioned; the water inlet COD concentration is reduced; meanwhile, the PH value is regulated in time; the water inlet index stability is ensured, so that the stability of biochemical treatment is ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] At present, the sewage treatment station built by the sugar factory is mainly to carry out biochemical treatment on the sugar juice washed out by various equipment in the sugar production process or the sugar juice produced in the process of evaporating and boiling sugar, and decompose and digest the sugar juice, because These sugar juices will cause the concentration of COD in the sewage to be extremely high, and if they are discharged without biochemical treatment, they will be punished. The sewage treatment station of the sugar factory often adopts the activated sludge treatment process. This treatment process requires the COD concentration and pH value of the influent to be continuously stable. collapse", because the COD concentration and PH value of the sugar factory sewage fluctuate greatly, so that the effe...
