Stirring wastewater treatment system and treatment method thereof

Abstract

The invention discloses a stirring wastewater treatment system and a treatment method thereof. The stirring wastewater treatment system comprises a basic assembly and a filtering and neutralizing assembly and an electrodeionization assembly, and the basic assembly comprises a metal wastewater tank; the filtering and neutralizing assembly comprises a filtering system communicated with the metal wastewater tank, an acid-iodine neutralizing system communicated with the filtering system, and a lifting and stirring assembly communicated with the acid-iodine neutralizing system; the electrodeionization assembly comprises a neutralizing water storage device communicated with the neutralizing system, a neutralizing water suction pump communicated with the neutralizing water storage device and an electrodeionization system connected with the neutralizing water storage device in an inserted mode. The acid-iodine neutralization system is designed to treat the metal wastewater, the acidolysis channel is designed to decompose the metal sludge in the metal wastewater, and meanwhile, the iodolysis channel is designed to neutralize acidic substances in the metal wastewater in acidolysis, so that the treatment of the metal wastewater is achieved.

Description

technical field [0001] The invention relates to a metal wastewater treatment system, in particular to a stirring wastewater treatment system. Background technique [0002] Wastewater refers to the general term for water discharged from residents' activities and runoff rainwater. It includes domestic sewage, industrial waste water, industrial waste water, and other useless water such as primary rainwater flowing into drainage pipes and canals. Generally, it refers to water that cannot be recycled after certain technical treatment or that the difficulty of purification after primary pollution cannot reach a certain standard. . [0003] The toxic and harmful substances in metal wastewater will remain in the body through the ingestion and absorption of plants, and then reach the human body through the food chain, causing harm to the human body. [0004] However, the existing metal wastewater treatment system is generally a simple filtration method, and the simple filtration ca...

Problems solved by technology

[0003] The toxic and harmful substances in metal wastewater will remain in the body through the ingestion and absorption of plants, and then reach the human body through the food chain, causing harm to the human body.

[0004] However, the existing metal wastewater treatment system is generally a simple filtration method, and the simple filtration can only filter the metal particles in the metal wastewater, even if the filter screen with a very small mesh number can only filter small granular metal substances, However, it is impossible to filter the metal sludge that is fused in the metal wastewater, so the traditional filtering method is often not ideal for the treatment of metal wastewater.
