Suspension type river water heavy metal pollution treatment device and using method thereof

Abstract

The invention discloses a suspension type river water heavy metal pollution treatment device and a using method thereof, and belongs to the technical field of river regulation. The suspension type river water heavy metal pollution treatment device comprises a treatment box. A storage box is fixedly connected on the top end of the treatment box, the storage box penetrates through the outer wall ofthe treatment box and extends into the treatment box; a connecting sleeve is fixedly installed on the outer wall of the treatment box, a suspension plate is in threaded connection with the outer wallof the connecting sleeve, two symmetrically-arranged floating balls are movably installed in the treatment box, linkage rods are fixedly connected to the top ends of the floating balls, and the linkage rods penetrate through the outer wall of the top of the treatment box. Uniform distribution of sulfide can be realized, sulfide aggregation can be effectively prevented and treatment of heavy metalions in river water is more comprehensive and thorough, the treatment effect is improved, secondary pollution to river water caused by addition of sulfide can be effectively avoided, and sulfide precipitate can be collected and recovered.

Description

technical field [0001] The invention relates to the field of river course management, and more specifically relates to a suspension type river water heavy metal pollution control device and a use method thereof. Background technique [0002] In recent years, my country's economy has developed rapidly, and the water resources needed in various fields have gradually increased. At the same time, the discharge of industrial wastewater and domestic wastewater has also increased day by day, which has seriously affected the river and caused serious pollution. The ecological environment around the river and the Residents' production and life are seriously threatened. Against this background, various localities have begun to increase the intensity of river regulation, the main purpose is to better protect the ecosystem of the river and control water pollution. Proceeding from the specific situation of river channel regulation and water pollution control, scientific and reasonable con...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, when the sulfide precipitation method is used to treat heavy metal pollution, the addition of sulfide is very troublesome, and the sulfide is easy to flow with the river water, and finally most of the sulfide accumulates, and the concentration of sulfide in some areas is too high. The concentration of sulfide in other areas is low, which leads to uneven distribution of sulfide and poor treatment effect
