A kind of printing and dyeing wastewater treatment equipment

Abstract

The invention discloses printing and dyeing wastewater treatment equipment, and relates to the technical field of wastewater treatment. The invention includes a water inlet device, a filter device, an anaerobic biological treatment device and a photocatalytic device. The water inlet device includes a set of first water pipes, three second water pipes are fixedly connected between the two first water pipes, and one first water pipe is fixedly connected There is a third water pipe, and a fourth water pipe is fixedly connected to the other first water pipe. The filtering device includes a first tank body, a blower and a second motor, and a first fixing plate is fixed on the inner wall of the first tank. In the present invention, the blower sends the outside air into the first tank body along the first slots on the air bag, realizes the stirring of the waste water, and cooperates with the first motor to drive several fan blades to rotate slowly, so that the first The wastewater in the tank is stirred more fully, so that the oil agent is easy to float up and flow out along the oil discharge pipe, and the stirring process is conducive to the adjustment of acid and alkali, so that the acid and alkali adjustment treatment effect in wastewater is better.

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.
