Treatment device for printing and dyeing wastewater

Abstract

The invention discloses a treatment device for printing and dyeing wastewater, and relates to the technical field of wastewater treatment. The treatment device comprises a water inlet device, a filtering device, an anaerobic biological treatment device and a photocatalytic device. The water inlet device comprises a set of first water pipes, three second water pipes are fixedly communicated betweenthe two first water pipes, a third water pipe is fixedly communicated to one of the first water pipes, and a fourth water pipe is fixedly communicated to the other first water pipe. The filtering device comprises a first tank, an air blower and a second motor, and a first fixing plate is fixed to the inner wall of the first tank. The treatment device has the advantages that the outside air is fedinto the first tank along a plurality of first slotted holes in an airbag by the air blower, the wastewater is stirred, and a first motor drives a plurality of blades to slowly rotate, so that the wastewater in the first tank is fully stirred, and oil agents easily float up and flow out along an oil drain pipe; acid and alkali adjustment is facilitated in the stirring process, so that the acid-alkali adjustment treatment effect on the wastewater is good.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a printing and dyeing wastewater treatment equipment. Background technique [0002] Printed products are one of the common items in our daily life. During the printing process of producing printed products, printing wastewater is often accompanied by the generation of printing wastewater. If it is discharged directly, it will seriously pollute the environment, especially the harm to soil and water sources. Therefore, it is necessary to treat the printing wastewater, so as to protect the environment and realize the recycling of water, which is conducive to the sustainable development of society. [0003] The structure of the existing printing and dyeing wastewater treatment equipment is too simple. In the process of filtering the wastewater, the oil agent in the wastewater is not sufficiently filtered and the filtering time is long, which cannot meet the production re...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of printing and dyeing wastewater treatment equipment, which sends the outside air into the first tank body along the first slots on the air bag through the blower, realizes the stirring of the wastewater, and cooperates with the first motor to drive Several fan blades rotate slowly, so that the wastewater in the first tank is stirred more fully, which solves the problem that the existing printing and dyeing wastewater treatment equipment does not sufficiently filter the oil in the wastewater and takes a long time to filter, which cannot meet the requirements of production. needs, and the acid-base adjustment of wastewater is uneven, which leads to the failure of wastewater discharge to meet the national requirements and affects the actual treatment of wastewater.
