Abstract

The invention discloses a sewage treating agent for treating heavy metal wastewater. A proper chemical treating agent and a proper biological treating agent are selected to be optimized according to the characteristic of heavy metal wastewater, useful substances generated in the growth processes of all microorganisms and secretions of the useful substances form matrixes and raw materials for intergrowth, then, a microbial community which is complex in component, stable in structure and wide in function and has various bacteria is formed through a mutual symbiosis and proliferation relationship, and the maximum united advantages can be exerted through reciprocity and mutual benefit in the purification process of the heavy metal wastewater under the synergistic effect of a chemical treating agent. The sewage treating agent is efficient in treating effect, capable of discharging wastewater up to the standard, low in cost and remarkable in economic benefit.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to a sewage treatment agent for heavy metal-containing wastewater. 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 instrumentation. Heavy metal (such as cadmium, nickel, mercury, zinc, etc.) wastewater is one of the most serious environmental pollution and one of the most harmful industrial wastewater to humans, and its water quality and quantity are related to the production process. Heavy metals in wastewater generally cannot be decomposed and destroyed, but can only transfer their existing positions and change their physical and chemical forms. [0003] At present, the treatment methods of heavy metal pollution are mainly physical and chemical methods, and bioremediation technology, as a more econo...
