Biological treatment beneficial enzyme for printing and dyeing wastewater

The necessity of reusing printing and dyeing wastewater

Printing and dyeing wastewater is organic pollution based on the composition of complex organic wastewater, the main object of treatment is BOD5, biodegradable or biodegradable slow organic matter, alkalinity, dye pigments and a small amount of toxic substances.  Although the biodegradability of printing and dyeing wastewater is generally poor, but in addition to some special printing and dyeing wastewater (such as pure chemical fiber fabric dyeing), it is still a biodegradable organic wastewater.  The main treatment method is biological treatment, and the necessary pretreatment and physical and chemical treatment should be supplemented.

The main biological treatment process is aerobic method. At present, activated sludge method, biological contact oxidation method, biological turntable and tower biological filter are used.  In order to improve the biodegradability of wastewater, anoxic and anaerobic processes have also been applied to the treatment of printing and dyeing wastewater.  The commonly used physical and chemical treatment processes are coagulated sedimentation and coagulated air flotation.  In addition, electrolysis method, biological activated carbon method and chemical oxidation method are sometimes also used in printing and dyeing wastewater treatment.  But through this process of textile printing and dyeing wastewater treatment, at most can only meet the standards of discharge, can not meet the water quality standards as textile printing and dyeing process water.

Kashion Aerobic Bacteria

Application

For the treatment of municipal sewage, various chemical wastewater, printing and dyeing wastewater, landfill leachate, food wastewater and other industrial wastewater, river treatment, black and smelly water, etc.

Function

* Due to spore flora have strong resistance to external harmful factors,the sewage treatment system has high load impact resistance and strong treatment capacity. When the sewage concentration changes greatly, the system can also operate normally to ensure the stable discharge of effluent.

* Aerobic bacteria can effectively remove BOD, COD and TSS, significantly improve the sedimentation capacity of solids in the sedimentation tank, and increase the number and diversity of protozoa;

*Quickly start and restore the system, improve the processing capacity and impact resistance of the system, effectively reduce the amount of surplus sludge, reduce the use of flocculants and other chemicals, and save electricity.
