Abstract

The invention belongs to the technical field of environment-friendly waste water treatment, and particularly relates to a microbial water treatment agent for heavy metal containing organic waste water. The microbial water treatment agent for the heavy metal containing organic waste water is prepared from dolomite powder, medical stone powder, anabaena azollae powder, water hyacinth powder, cladosporium sphaerospermum, Indian mustard powder, citrobacter amalonaticus, penicillium digitatum, hydroxyapatite powder, zeolite powder, citric acid, succinic acid, dicranopteris linearis powder, rhus lacquer powder, horse radish peroxidase, suillus bovines, laccaria amethystea, phanerochaete chrysosporium, bacillus subtilis, trichoderma koningii, trichoderma viride, bacillus mojavensis and klebsiella variicola. The microbial water treatment agent is high in treatment efficiency, low in running cost, wide in pH and temperature condition range, high in adsorbent reproducibility and free of secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of waste water environmental protection treatment, and in particular relates to a microbial water treatment agent for organic waste water containing heavy metals. Background technique [0002] In recent years, industries such as metallurgy, electroplating, tanning and catalyst preparation have produced a large amount of organic wastewater containing high concentrations of heavy metals, which will eventually be discharged into the natural water system. If these wastewaters are not treated, they will cause serious damage to human health and life. Therefore, it is urgent to develop new methods for treating such wastewaters with high efficiency and harmlessness. [0003] Organic wastewater containing heavy metals is the most common and important industrial wastewater. This kind of wastewater contains a large amount of high-concentration heavy metals and organic pollutants that are difficult to degrade, such as d...
