Efficient electro-deposited heavy metal cleaning system

Abstract

The invention provides an efficient electro-deposited heavy metal cleaning system which comprises a filtering membrane, an efficient heavy metal electro-deposition membrane, a delivery pump, a reaction tank, a control system, a feedback regulation system and a supporting structure. The delivery pump feeds tail water into the reaction tank; heavy metal ions in the tail water have a reduction reaction in the process of passing through the efficient heavy metal electro-deposition membrane, and then are uniformly deposited on the metal electrode filtering membrane; the water subjected to treatment is fed back to a production workshop through the delivery pump; the feedback regulation system regulates the adding amount of heavy metals in an electroplating workshop according to the heavy metal ion concentration of the tail water; the control system monitors the effective running of the components. The technique is a cleaning technique, and implemented by taking electrons as a cleaning agent; the efficient electro-deposited heavy metal cleaning system is applicable to more than 98% of heavy metals in existing known industrial wastewater, and the clearance rate of heavy metals is over 99.9%, so that the problem that an existing heavy metal treatment technique is poor in ultra-low concentration treatment effect is effectively solved. The cleaning system is specially designed according to the characteristics of the compositions of industrial wastewater, and has the characteristics of simple structure, high efficiency, no secondary pollution, and the like.

Description

technical field [0001] The patent of the present invention relates to a high-efficiency electrodeposition heavy metal cleaning system, in particular to the design of a membrane structure and monitoring and control technology. Background technique [0002] With the development of industry, heavy metal pollution has become a problem that cannot be ignored by human beings. Heavy metal pollution has the characteristics of refractory degradation, long pollution cycle, and great harm, and it is becoming more and more serious. This has prompted governments of all countries to invest huge sums of money to promote heavy metal pollution. Research and development and application of treatment technology, various heavy metal pollution treatment technologies have been developed and implemented. [0003] Because the existing heavy metal pollution control technologies have their own advantages and disadvantages, and will cause pollution transfer, it is easy to cause secondary pollution, and...

AI Technical Summary

Problems solved by technology

[0003] Since the existing heavy metal pollution treatment technologies have their own advantages and disadvantages, and will cause pollution transfer, it is easy to cause secondary pollution, and it is difficult to deal with ultra-low concentration of harmful heavy metal pollution

In practical applications, several methods are often used for comprehensive treatment, which increases the initial investment cost, and the later maintenance is difficult and costly. In particular, the existing treatment methods are only designed for tail water and do not involve any link in the electroplating process, so early control cannot be realized
