Printing and dyeing wastewater treatment device and control method thereof

Abstract

The invention discloses a printing and dyeing wastewater treatment device and a control method thereof. A buffer filter of the treatment device comprises a cuboid-shaped base and a cylinder body of the buffer filter, and cuboid-shaped connecting pieces are arranged at the lower end of the outer side wall of the cylinder body of the buffer filter at equal intervals; vertical buffer equipment is connected between the connecting piece and the cuboid-shaped base, and a drainage hole used for draining filtered printing and dyeing wastewater is formed in the lower end of one side wall of the cylinder body of the buffer filter. The problems that in the prior art, a buffer filter of a sampling detection device used in a printing and dyeing wastewater treatment system is complex in structure and difficult to replace or maintain, the filtering period of the buffer filter is large, the performance is poor, and an operator is tedious in operation, time-consuming and labor-consuming, in cold days,the buffer performance of filtering of a buffer filter is poorer, a sleeving piece of sleeving piece equipment connected with the output end of a sampling water inlet pipe and the connector in a sleeving mode is damaged, a connected closed wall is often damaged, and a seam often occurs in the sleeving piece are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment device for printing and dyeing wastewater and a control method thereof. Background technique [0002] Wastewater discharged from printing and dyeing, wool dyeing and finishing and silk factories mainly processing cotton, hemp, chemical fiber and their blended products, and silk. The type of fiber and processing technology are different, and the water quantity and quality of printing and dyeing wastewater are also different. Among them, the amount of wastewater in printing and dyeing factories is relatively large, and 1 ton of textiles for printing and dyeing consumes 100-200 tons of water, of which 80% to 90% are discharged as wastewater. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the most difficult industrial wastewate...

Problems solved by technology

[0008] In order to solve the above problems, the present invention provides a treatment device for printing and dyeing wastewater and its control method, which effectively avoids the complexity of the buffer filter structure used in the sampling and detection device in the printing and dyeing wastewater treatment system in the prior art, which makes replacement or maintenance The buffer filter is difficult, the filter cycle of the buffer filter is long, the performance is not good, the operation is cumbersome and time-consuming for the operator, the buffer performance of the buffer filter is worse when it is cold, and the output end of the socket sampling inlet pipe is connected to the The socket equipment of the joint has socket damage, the connected closing wall is often damaged, and there are often gaps in the socket.
