Industrial water treatment device and self-cleaning mechanism thereof

Abstract

The invention discloses an industrial water treatment device. The industrial water treatment device includes a sewage groove, an alkali liquor tank, a chemical water treatment device, an overflow pool, an inclined pipe sedimentation pool and a filter. The sewage groove used for storing industrial sewage is connected with an electrochemical water treatment device through a pipeline, a sewage pump is installed on the pipeline, the alkali liquor tank is connected to the pipeline through a dosing pipe, and a metering pump is installed on the dosing pipe. The industrial water treatment device has the beneficial effects that the industrial water treatment device can quickly perform electrochemical treatment on the industrial sewage, and after the electrochemical treatment is completed, the watercan be further filtered to ensure the quality of the water treatment, meanwhile, a return structure formed by a water outlet pipe and a return pipe enables unqualified effluent to return to the sewage groove for retreatment based on the test results of a water quality analyzer, and the quality of the effluent is effectively guaranteed; and in addition, the arranged self-cleaning mechanism can automatically backwash a filter element of the filter to ensure the efficient operation of the filtration.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an industrial water treatment device and a self-cleaning mechanism thereof. Background technique [0002] At present, with the rapid development of my country's economy, the problem of industrial water pollution is becoming more and more serious. Although the addition of chemical agents to industrial wastewater has solved water pollution to a certain extent, the added chemical agents themselves also have major hidden dangers. Electrochemical treatment technology is an important method to solve the negative problems caused by the use of chemical agents in the field of industrial water treatment. [0003] Electrochemical water treatment technology is more and more widely used in today's water treatment industry, especially in the fields of refractory biodegradable organic wastewater, complex heavy metal polluted wastewater, electroplating and surface treatment industry wastewater, oilfi...

AI Technical Summary

Problems solved by technology

[0005] It has the characteristics of simple structure, convenient use, low cost, and high degree of density. At the same time, it has more obvious treatment effects than traditional sewage treatment devices, reducing turbidity, suspended solids, total hardness, and organic matter in sewage. The treated sewage can be discharged normally or recycled and reused; however, after the electrochemical treatment, it still needs to be dosed for the next step of filtration and cleaning. The process is complicated and the cost is relatively high. There is no corresponding detection device for the final effluent. Water quality cannot be guaranteed
