Problems solved by technology

This method is to use adsorbent to remove heavy metal ions in wastewater, but the disadvantage of this method is that the price of adsorbent is too expensive
[0016] Under the current technical conditions, the increase of equipment construction cost and operating cost for treating heavy metal industrial sewage will become inevitable. The existing traditional process and treatment method have the disadvantages of long process flow, complicated control, large land occupation and high treatment cost.

Abstract

The invention discloses a device and method for removing heavy metal ions in industrial sewage.The device is composed of an industrial sewage pond, a sewage pumping system, a treatment pond, a clean water pipe, a clean water tank, a treatment pond support and a control system.The control system starts the sewage pumping system to input industrial sewage containing heavy metal ions from the upper side wall into the treatment pond, and clean water treated by the treatment pond is drained into the clean water tank through the clean water pipe.According to the device and method for removing heavy metal ions in industrial sewage, the structure is novel and reasonable, the heavy metal ion removal rate is high, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of industrial sewage treatment and purification, and in particular relates to a device for removing heavy metal ions in industrial sewage and a removal method thereof. Background technique [0002] With the rapid increase of industrial sewage discharge, a large amount of heavy metal pollutants are discharged into the living environment. Under certain conditions, some heavy metals (such as mercury) can also be converted into more toxic organic substances under the action of some microorganisms. In addition, toxic heavy metals can stay and accumulate in the environment for a long time, accumulate step by step through the food chain, and finally enter the human body, and even harm babies through genetics or breast milk. Therefore, the treatment technology of heavy metal pollutants has become a research hotspot, and the results have great practical significance. [0003] Heavy metal pollutants are distributed in the atm...
