Commonly used biological treatment methods for printing and dyeing wastewater

Biologicalenzyme

(1) enzyme preparation: The use of biological enzyme preparation to treat sewage treatment, purification of the environment than other biological methods have high efficiency, fast speed, good effluent, no secondary pollution. Laccase, lignin peroxidase, alkalinase and so on are used to treat printing and dyeing wastewater.

(2) Decolorizing microbial preparations for sewage treatment: the microorganisms in the activated sludge of sewage treatment plant are purified respectively to extract the microorganisms with good decolorizing effect on dyes, and then cultured. There are abundant microbial varieties in activated sludge, including bacteria, fungi, micro-animals and other biological species. The microorganisms in activated sludge constitute an ecosystem, in which autotrophic microorganisms are the main type.

Bacteria feed on organic matter in the environment, and bacteria will become the prey of some protozoa or later animals. Protozoa is called to prey on each other. Different metazoa may also be in different nutritional levels of a variety of micro-cattle to form a messy food web.

Kashion Anaerobic

* Anaerobic bacteria can hydrolyze insoluble organic matter in water into soluble organic matter, converts hard-to-biodegradable macromolecular organic matter into easily biodegradable small-molecule substances, so as to improve the biodegradability of sewage, lay the foundation for subsequent biochemical treatment.

*Anaerobic bacteria are also compounded with highly active biological enzymes, such as amylase, protease, and lipase, which can help the bacteria quickly decompose and transform organic matter, and increase the rate of hydrolysis and acidification.

* Improve methane production rate and efficiency in anaerobic system, and reduce the content of suspended solids in water.
