Abstract

The invention discloses a textile waste water treatment system. The system comprises a regulating pool for collecting waste water, a neutralization regulating pool, a hydrolysis acidification pool, a biological contact oxidation pool and an air floating pool, wherein the regulating pool is sequentially communicated with the neutralization regulating pool, the hydrolysis acidification pool, the biological contact oxidation pool and the air floating pool; the hydrolysis acidification pool is internally provided with a diving mixer and an elastic solid packing. The textile waste water treatment system further comprises a neutralization mechanism for neutralizing and regulating the PH value of waste water in the neutralization regulating pool and a flocculant feeding mechanism and a coagulant feeding mechanism which are both arranged in front of the air floating pool. When the PH regulation system works, a submersible sewage pump, a pipeline mixer, a PH meter and a control valve coordinately control and regulate, the PH value of the waste water raised up by the submersible sewage pump is measured by the PH meter, and the waste water automatically enters the next treatment procedure when the PH value meets relevant standards and then a compliance PH meter valve is opened. The treatment process is simple, the effluent water quality is stable, and the operation and control of the system are convenient.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a textile wastewater treatment system. Background technique [0002] The water quality of textile wastewater is complex, and the sources of pollutants can be divided into two categories: one is from the entrainment of the fiber raw materials itself; the other is the size, oil, dyes, chemical additives, etc. used in the processing process. The various wastewater and water quality characteristics of discharge are: 1) Desizing wastewater, desizing wastewater is alkaline organic wastewater, containing various pulp decomposition products, lint, acid and enzymes and other pollutants. The degree of contamination varies with the type of slurry. In the past, natural starch was mostly used as slurry, and the BOD in the water was high. In recent years, it has been gradually replaced by chemical slurry, such as polyvinyl alcohol (PVA). The BOD in the wastewater is very low, but the...
