Abstract
The invention discloses a sewage treatment device in a garment production process. The sewage treatment device comprises a sand precipitation pool, a grating pool, an adjusting pool, a hydrolysis acidification pool, a first aerobic pool, an oxidation ditch, a second aerobic pool, a precipitation pool, a fan, a disinfection pool, a sludge pool and a filter press, wherein the sand precipitation pool, the grating pool, the adjusting pool, the hydrolysis acidification pool, the first aerobic pool, the oxidation ditch, the second aerobic pool, the precipitation pool, the fan and the disinfection pool are sequentially connected through conveying pipelines, the sludge pool is connected with the sludge inlet of the filter press through a sludge pipeline, the air outlet of the fan is connected witha ventilating pipeline, and aeration pipes communicated with the pool bottom are arranged in the first aerobic pool, the oxidation ditch and the second aerobic pool. According to the present invention, with the sewage treatment device, the sewage pollutant extraction efficiency can be effectively improved, the operation is stable, the good impact load resistance is provided, the degradation efficiency is high, the treatment cost is saved, and the sewage treatment device is simple, practical and convenient to manage.
Description
technical field [0001] The present invention relates to the technical field of sewage treatment in garment factories, in particular to a sewage treatment device and method in the garment production process. Background technique [0002] In the garment factory, during the garment production process, the garment needs to undergo a washing process. During the washing process, some washing conditioners need to be added, such as cold water enzyme, washing powder, softener, pumice stone, potassium permanganate, 50% hydrogen peroxide Etc., the production wastewater discharged by this process mainly contains eluted dyes and added washing water regulators. The main pollution indicators are: LAS: 72~100mg / L; CODCr: 900mg / L; BOD5: 250mg / L; SS: 300mg / L . At present, the biochemical treatment effect of traditional sewage treatment methods in the garment production process is poor, and most of the harmful organic substances in the water body cannot be degraded, so the discharged sewage c...
