Primary clean water treatment device for wool scouring industrial wastewater

Abstract

The invention discloses a primary clean water treatment device for wood scouring industrial wastewater. The primary clean water treatment device comprises a flocculent precipitating tank, wherein a supporting outer frame is fixedly connected to an outer wall of the flocculent precipitating tank, one end of an outer wall of the top end of the flocculent precipitating tank is communicated with a wastewater inlet pipe, a flocculant feeding opening is formed in an outer wall of the top end of one side, far from the wastewater inlet pipe, of the flocculate precipitating tank, a hollow threaded fixed block is in embedded connection to the middle position of the outer wall of the top end of the flocculate precipitating tank, and an accelerating evenly-stirring threaded rod is in threaded connection to an inner annular wall of the hollow threaded fixed block. The invention relates to the technical field of water purifying equipment. The primary clean water purifying device for the wood scouring industrial wastewater aims at a primary water purifying process of the wood scouring industrial wastewater and shortens required time of wastewater flocculation precipitation; meanwhile, precipitation impurities are filtered and brushed out in a double-layer mode, then the surface of a filter screen can be automatically cleaned, service cycle of the filter screen is prolonged, and the efficiencyand a water purifying effect of a clean water purifying process are further ensured.

Description

technical field [0001] The invention relates to the related technical field of water purification equipment, in particular to a primary water purification treatment device for wool washing industrial wastewater. Background technique [0002] Wool washing industrial wastewater is the wastewater discharged during the processing and cleaning process of wool, the raw material of woolen fabrics. Washing 1 ton of wool produces about 35m of waste water 3 . The waste water mainly contains lanolin, sheep sweat (organic acid, potassium salt), sand, soil, forage seeds, etc., accounting for 25-40% of the weight of the raw wool. The wastewater is gray-brown milky (dilution factor up to 1:1000-1800). For wool washing industrial wastewater, the coagulation and purification process by chemical method is an essential step in its sewage treatment. Electrolyte is added to the colloidal turbid liquid to condense the colloidal substances in the water to separate it from the water. [0003] A...

AI Technical Summary

Problems solved by technology

[0003] At present, the flocculation and sedimentation process of wool washing industrial wastewater takes too long, and in the sedimentation and filtration process, the filter elements or screens need to be replaced or cleaned frequently, which increases the treatment cost of factory sewage and also affects the treatment efficiency of sewage
