How to treat wastewater from chemical plants to meet standards?

The standardized treatment of wastewater in chemical plants requires a systematic process combination, with the core being the efficient removal of pollutants through "pretreatment+biochemical treatment+deep treatment". Here is the specific plan:
1、 Pre treatment: Removing the "Golden Bell Cover" of pollutants
Physical method: Oil separation tank removes suspended impurities, and air flotation method is used to treat high turbidity wastewater.
Physicochemical method: Iron carbon microelectrolysis degrades organic matter through electrochemical reactions, enhancing biodegradability.
2、 Biochemical treatment: Microbial "group combat"
Anaerobic treatment: UASB/IC reactor degrades large molecule pollutants with a COD removal rate of over 85%.
Aerobic treatment: Control dissolved oxygen to 2-3mg/L, and achieve a removal rate of over 95% for ammonia nitrogen.
3、 Deep Processing: Ultimate Control to Ensure Stable Compliance
Chemical method: Fenton reagent oxidation method decomposes recalcitrant organic compounds.
Physical method: Activated carbon adsorbs residual pollutants, and RO reverse osmosis membrane intercepts salt.
4、 Case reference
Pesticide wastewater: Micro electrolysis pretreatment+two-stage anaerobic+aerobic+Fenton oxidation, COD stable below 80mg/L.
Dye wastewater: water quality homogenization+iron carbon microelectrolysis+catalytic oxidation+composite biological treatment, color removal of 99%.
5、 Technical optimization
Resource recycling: All oily wastewater is reused, and 100% of saline wastewater is discharged in compliance with standards.
Cost control: The operating cost of the combined process is 10-20 yuan/ton of water, and the recycled water is used for equipment flushing.
