Embodiment Construction

[0018] Such as figure 1 Shown, a kind of jet weaving waste water treatment process comprises the following steps successively:

[0019] a) Wastewater pretreatment: The spray weaving wastewater is cut off by a fixed grid to cut off large particles of suspended impurities such as waste silk, waste cloth, and garbage with a particle size greater than 5mm, and then flows into the waste water pool by itself. The suspended oily impurities in the waste water pool float on the The liquid level, the pretreated water is obtained after the suspended oil impurities are removed by oil separation, and the pretreated water is lifted by the lift pump into the pH adjustment tank;

[0020] b) PH adjustment: use a stirrer to add PAC agent to the pretreated water in the water inlet pipe, and then add NaOH to the pH adjustment tank to neutralize the acid and alkali to keep the pretreated water in a neutral state; the PAC agent is polymerized chlorine For aluminum, a blower can be used to blow air...

Abstract

The invention discloses a process for treating jet weaving wastewater. The process sequentially comprises the following steps of: 1) pre-treating the wastewater; b) adjusting pH; c) treating precipitates; d) gasifying and layering; e) sterilizing by using ultraviolet rays and ozone; and f) treating sewage. Various treatment modes such as filtering, physical and chemical treatment, agent adding and coagulation, pressurization and floatation, water molecule refining, an UV / O3 light wave rapid disinfection and sterilization system and the like are adopted in the whole treatment process; water molecules and air are mixed and micronized according to a high-pressure floatation principle, and dirt and sundry particles in water can be subjected to floatation separation with raw water so as to form a floating layer state; sterilization is performed by using UV / O3 in a micronizing process so as to remove disease-causing germs and microorganisms from water quickly; and biochemical oxygen demand (BOD) content, chemical oxygen demand (COD) content and suspended solids in the wastewater are greatly reduced by secondary filtering, so the requirement of recycling the jet weaving wastewater can bemet.

Description

【Technical field】 [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment process for water jet weaving waste water. 【Background technique】 [0002] In recent years, water-jet weaving has become an important part of the textile industry due to its low energy consumption, fast speed and high weaving efficiency. However, the warps of most products need sizing to meet the weaving requirements. Because in the weaving process, the slurry falls and dissolves in water under repeated friction, which brings water pollution and produces a large amount of weaving wastewater. The COD content in wastewater is extremely high. If it is not treated, it will cause serious water pollution, causing the water to turn black and smelly, which cannot meet environmental protection requirements. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a jet weaving wastewater treatment...
