Water-jet loom wastewater recycling treatment method and recycling treatment system

Abstract

The invention discloses a water-jet loom wastewater recycling treatment method and recycling treatment system. Water-jet loom wastewater is subjected to sundries removal by virtue of a grille and automatically flows into an adjusting tank for adjusting the flow and homogenizing the water quality; the sundries-removal water-jet loom wastewater enters a coagulation zone of an air-flotation coagulation unit, the coagulation zone is divided into three cells, wastewater and a coagulant firstly enter a middle cell, then bilaterally enter an air-flotation contact chamber of the air-flotation coagulation unit by virtue of cells located at both sides of the middle cell and are in full contact with and mixed with air-dissolved water and formed scum is skimmed by virtue of scum-water separation in an air-flotation zone of the air-flotation coagulation unit; air-flotation separation supernatant is pumped into a filter for filtering to remove suspended substances; filtered effluent water is disinfected by virtue of ultraviolet and is recycled as water for the water-jet loom. In combination with the water-quality requirement on water for the water-jet loom, the invention provides the water-jet loom wastewater physico-chemical recycling treatment system which has the advantages of mature technology, high efficiency, good effect, low investment and low operating cost, is reliable and safe and has optimized combination of treatment units.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a water jet loom wastewater recycling treatment method and a recycling treatment system. Background technique [0002] Water-jet looms are the fastest-growing shuttleless looms in textile machinery in recent years. million tons. For a long time, there have been many studies on the treatment of water jet loom water, but there is a lack of research on the reuse of water jet loom wastewater. With the improvement of environmental protection awareness and the shortage of water resources, water jet loom wastewater reuse treatment has attracted more and more attention, especially in countries with water shortages in my country, due to the increasingly prominent problem of water resource scarcity, it has become a constraint on social economy. One of the main factors of development. Therefore, it is of great practical significance to reduce wastewater discharge and save wat...

Problems solved by technology

[0007] However, the system mainly has the following shortcomings: due to the use of a two-stage mud-water separation system of precipitator + air flotation device, the facilities are large and the investment is high. At the same time, the effluent is not sterilized and does not meet the biological indicators, which will lead to the growth of organisms on the water jet loom , affecting the reuse effect. In addition, using conventional chemicals, when the concentration of raw water is high, there are certain difficulties in the quality of wastewater reuse.

But the investment cost and operating cost are higher

At the same time, due to the extremely poor biochemical properties of water jet loom wastewater, it is difficult to use biochemical technology to operate, and nutrient solution must be added to normal operation, which is unreasonable in technology and economy
