Why is the waste water treatment cost of chemical enterprises generally high

Because chemical wastewater belongs to the category of high difficulty wastewater treatment, in many industrial wastewater treatment, the cost of chemical wastewater treatment is higher than other wastewater treatment.The wastewater discharged by chemical enterprises has high concentration of pollutants, complex composition, more toxic and harmful substances, more biodegradable substances, and higher chroma, which are the main reasons for its difficulty in treatment and the higher treatment cost.

Chemical wastewater treatment cost price

In order to make the treatment of chemical wastewater reach the standard, a single treatment process can not meet the requirements, and a variety of treatment processes need to be used together, which relatively increases the cost of enterprises.At present, most of the treatment methods of chemical wastewater mainly have two kinds: one is based on chemical catalysis process treatment, the other is to adopt pretreatment method to improve the biodegradability of wastewater, and then adopt biochemical method treatment.

In the actual chemical wastewater treatment project, the chemical catalysis method needs high temperature and high pressure to enhance the effect. Therefore, when this method is used, the cost of the equipment used in the field is relatively high and the dosage of the agent is also large, so it is not recommended to use this method.

Biochemical treatment is relatively economical and efficient.Chemical wastewater biochemistry is poor, so the use of biochemical treatment, first of all to wastewater pretreatment, in the pretreatment stage to reduce the toxicity and load of wastewater, improve the biodegradability of wastewater, and then biochemical treatment, which can make the wastewater treatment standards, and the operation cost is also greatly reduced.
