Repair agent for deep treatment of electroplating wastewater

Abstract

The invention discloses a repair agent for deep treatment of electroplating wastewater. The repair agent is characterized in that the repair agent includes the following components in parts by mass: 10-20 parts of slaked lime, 15-30 parts of clay, 10-15 parts of polyaluminium chloride, 4-7 parts of Bacillus cereus microbial agents, 5-15 parts of iron dust, 12-18 parts of wheat bran, 3-8 parts of shell powder, 8-15 parts of synthetic zeolite, 6-12 parts of bentonite and 5-10 parts of brown algae. The repair agent includes the slaked lime, the clay, the polyaluminium chloride, the Bacillus cereus microbial agents, the iron dust, the wheat bran, the shell powder, the synthetic zeolite, the bentonite and the brown algae; the iron duct and other dust are used to adsorb heavy metals, and microbial agents are used to remove bacteria from the electroplating wastewate, so that the deep treatment of electroplating wastewater is realized, and the removal rate of the heavy metals can reach 90%. Thus, the repair agent has strong repair capacity to the electroplating wastewater.

Description

technical field [0001] The technical field of electroplating sewage treatment of the present invention particularly relates to a restoration preparation for advanced treatment of electroplating sewage. Background technique [0002] Electroplating technology is widely used in machinery and electronics industries. However, the composition of wastewater produced in electroplating production is very complex. In addition to cyanide (CN-) and acid and alkali, heavy metals are potentially harmful wastewater categories in the electroplating industry. These substances are serious Harmful to the environment and human health. The polluted electroplating sewage containing heavy metals enters the soil through various channels, resulting in the enrichment of corresponding heavy metal elements in the soil. Soil pollution not only affects the yield and quality of agricultural products, but also involves the quality of the atmosphere and water environment, and can endanger the life and heal...

Problems solved by technology

[0003] At present, the remediation preparations for electroplating sewage can remove some heavy metals in electroplating sewage, but they cannot deeply remove heavy metals in electroplating sewage. A large part of heavy metals will still enter the soil or water sources. There is an urgent need for a repair preparation for deep treatment of electroplating sewage
