Efficient textile printing and dyeing wastewater treatment equipment

Abstract

The invention relates to the technical field of wastewater treatment, and discloses efficient textile printing and dyeing wastewater treatment equipment which comprises a wastewater tank and a treatment box, a water inlet pipe is fixedly mounted between the outer wall of the bottom of the right side of the wastewater tank and the right side wall surface of the treatment box, and a water pump is mounted on the water inlet pipe; and a water outlet pipe is fixedly installed between the left side top wall surface of the wastewater tank and the left side wall surface of the treatment box, a sealed box cover is installed at the top of the treatment box, a hydraulic rod horizontally facing the right side is fixedly installed in a left side cavity of the treatment box, and a filtering device is arranged in the cavity of the treatment box. According to the efficient textile printing and dyeing wastewater treatment equipment disclosed by the invention, textile wastewater in the treatment box cavity flows through from right to left, two filter cartridges and two filter screens of the filtering device do translational motion in the treatment box cavity from left to right, and the direction of filtering the wastewater by the filtering device is opposite to the passing direction of the wastewater; and the filtering efficiency of the filter screen and the filter cartridges on the textile wastewater is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an efficient textile printing and dyeing wastewater treatment equipment. Background technique [0002] Textile wastewater is mainly wastewater containing organic matter such as natural impurities, fat, and starch produced during the cooking, rinsing, bleaching, and sizing of raw materials. Printing and dyeing wastewater is produced in multiple processes such as washing and dyeing, printing, and sizing. It contains a large amount of organic matter such as dyes, starch, cellulose, lignin, and detergent, as well as inorganic matter such as alkali, sulfide, and various salts. Very strong. Wastewater is characterized by high concentration of organic matter, complex components, deep and changeable color, large pH changes, and large changes in water quantity and quality. It is a difficult-to-treat industrial wastewater. [0003] When textile wastewater is being treated, th...

Problems solved by technology

[0003] When textile wastewater is being treated, the first step is to physically filter it to filter impurities, hard dirt, and sediment in the wastewater. The design of textile wastewater filtration in the prior art is generally relatively simple, and the wastewater is passed through a flat The filter screen filters impurities, dirt, etc. on the surface of the filter screen. First, the filter screen is fixed and the relative filtration speed that only allows wastewater to pass through is low, which leads to low wastewater treatment efficiency. Secondly, the complete flat filter screen is easy to The problem of being blocked by impurities
