Chemical wastewater treatment solutions

Wastewater type: pharmaceutical wastewater. With the development of the pharmaceutical industry, pharmaceutical wastewater has gradually become one of the important sources of pollution.

Wastewater hazards: pharmaceutical wastewater is currently a type of wastewater that is difficult to treat. Due to its complex composition, high organic content, high toxicity, deep chroma and high salt content, especially poor biodegradability and intermittent discharge, it is impossible to directly use biochemical treatment processes.

Wastewater source: pharmaceutical wastewater mainly includes four categories: antibiotic production wastewater, synthetic drug production wastewater, Chinese patent medicine production wastewater, and washing water and flushing wastewater from the production process of various preparations.

ENCO treatment process: ENCO uses a multi-effect evaporator to treat pharmaceutical wastewater, which greatly reduces the cost, makes this process more in line with production practice, and increases the reliability and feasibility of the pharmaceutical wastewater treatment process.

Characteristics of pharmaceutical wastewater: It varies greatly due to different types of drugs and production processes. It usually has complex composition, many types of organic pollutants, high concentration, high and volatile COD and BOD values, many difficult-to-degrade substances, and strong toxicity.

Difficulties in pharmaceutical wastewater treatment: The wastewater from pharmaceutical factories is usually discharged intermittently, and the types and quantities of products vary greatly, resulting in large changes in the water quality, water volume and types of pollutants in the wastewater, which brings great difficulties to treatment.
