Embodiment Construction

[0028] Such as figure 1 Shown, the sewage treatment method in the clothing production process of the present invention specifically comprises the following steps:

[0029] 1) Filtration: Sewage enters the grid well 1, and the grid in the grid well 1 is filtered to remove large solid impurities and part of solid suspended matter in the sewage;

[0030] 2) Adjustment of water quality and water quantity: the above-mentioned sewage that removes large solid debris and part of solid suspended matter enters the regulating tank 2, and the regulating pond 2 adjusts the water quality and water quantity to be uniform;

[0031] 3) Flocculation reaction: The adjusted sewage enters the flocculation reaction tank 3, and the colloidal substances and suspended solids in the sewage are fully mixed with the coagulant and flocculant in the flocculation reaction tank 3 under the agitation of the agitator. , forming solid flocs;

[0032] 4) Solid-liquid separation: the above-mentioned sewage cont...

Abstract

The invention discloses a sewage treatment method in a garment production process. The sewage treatment method comprises the following steps: filtering, adjusting of water quality and water quantity, flocculation reaction, solid-liquid separation, hydrolytic acidification, first biodegradation, reducing of dissolved oxygen concentration, second biodegradation, solid-liquid separation and discharging. The sewage treatment method in the garment production process is simple and practical, convenient to manage, strong in operation stability, small in maintenance work, and good in sewage treatment effect, meets the standard requirements, and simultaneously can adapt to large change in sewage quality and quantity.

Description

technical field [0001] The invention relates to a sewage treatment 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, and the main pollution indicators are: LAS: 72-100 mg / L; COD Cr :900 mg / L; BOD 5 : 250 mg / L; SS: 300 mg / 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 cannot meet the "Discharge Standards for Pollutants in Textile Dyeing and Finishing Indu...
