Problems solved by technology

[0004] However, at present, my country's heavy metal wastewater treatment technology lags behind. The use of common processes and traditional heavy metal wastewater treatment methods cannot effectively reduce the heavy metal ion content in wastewater, resulting in the treated water being unusable and high wastewater treatment costs.

Abstract

The invention discloses a heavy metal wastewater treatment agent which comprises the following raw materials in parts by weight: 13-15 parts of sodium carboxymethylcellulose, 11-13 parts of sodium cumenesulfonate, 17-19 parts of coal ash, 4-6 parts of carrageenan, 8-10 parts of ferrous sulfate, 9-11 parts of kieselguhr, 12-14 parts of polymeric phosphate-ferric chloride, 9-11 parts of calcium chloride, 2-4 parts of chitosan, 3-5 parts of koning trichoderma, 2-4 parts of koning trichoderma, 3-5 parts of sodium diacetate, 6-8 parts of peracetic acid, 11-13 parts of ethanol, 7-9 parts of calcium bentonite and 18-20 parts of water. The heavy metal wastewater treatment agent is capable of reducing contents of heavy metal ions in metal wastewater, is free of toxic substance, good in decoloring effect, relatively simple in production method and applicable to industrial production, and water treated with the agent is odorless and can be recycled.

Description

technical field [0001] The invention relates to a heavy metal wastewater treatment agent, which belongs to the field of wastewater treatment. Background technique [0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged from industrial production processes such as mining and metallurgy, machinery manufacturing, chemical industry, electronics, and instruments. Heavy metal (such as cadmium, nickel, mercury, zinc, etc.) wastewater is the most serious environmental pollution and harmful to the environment. One of the most harmful industrial wastewater to human beings, its water quality and quantity are related to the production process. Generally, heavy metals in wastewater cannot be decomposed and destroyed, but can only transfer their existing location and change their physical and chemical forms. [0003] The treatment method of heavy metal wastewater at the present stage is to firstly reform the production process, do not use or use less toxic ...
