1.1Key Pollutants:
Pesticide production wastewater is a typical high-concentration organic wastewater with a complex composition. It contains various chemical substances, some of which have stable molecular structures and are difficult for microorganisms to degrade. These characteristics pose significant challenges for wastewater treatment.
1.2 Key Characteristics
1. Pesticide wastewater contains a high concentration of organic matter.
2. Complex composition, the pollutants include not only raw materials but also numerous by-products and intermediates.
3. High toxicity and poor biodegradability. In addition to pesticides and intermediates, the wastewater often contains toxic substances such as aromatic compounds, phenols, arsenic, and mercury, which inhibit biological treatment processes.
4. The water quality and flow rate of pesticide wastewater are unstable.
