Characteristics of chemical wastewater:
Complex composition: contains a variety of organic and inorganic substances, and the composition is variable.
High concentration: high content of pollutants.
High toxicity: often contains toxic and harmful substances.
Poor biodegradability: some chemical wastewater is difficult to be degraded by microorganisms.
Difficulties in chemical wastewater treatment:
Effective removal of complex components.
Degradation of high-concentration pollutants.
Improving biodegradability to adapt to subsequent biological treatment.
Key points of chemical wastewater treatment:
Targeted design of pretreatment, such as adjusting water quality and quantity, and removing some difficult-to-treat substances.
Selecting a suitable combination of treatment processes.
Paying attention to operation management and parameter control.
Case analysis of chemical wastewater treatment:
A chemical plant: using the "advanced oxidation + anaerobic + aerobic" process to treat wastewater. First, the biodegradability of wastewater is improved through advanced oxidation, and then the organic matter is further degraded through anaerobic and aerobic processes, and finally the discharge is up to standard.
Another chemical company: using the process route of "physical and chemical pretreatment + biological treatment + deep treatment" to successfully treat chemical wastewater and reuse part of the wastewater.
