Introduction of Pharmaceutical Wastewater Treatment Process - For pharmaceutical wastewater with high organic concentration, complex composition and certain toxicity, Lanchen Environmental Protection Co., Ltd. mainly adopts physicochemical pretreatment + biochemical treatment process. In actual engineering, the sewage treatment system runs normally and the effluent is stable.
The quality of pharmaceutical wastewater is about 2000 kinds of commonly used drugs produced in China. The types and quantities of raw materials used in different types of drugs are different. The production process and synthetic route are also different, which leads to the quality of wastewater produced by different varieties of drugs. There are also large differences in characteristics. The treatment of a wide variety of complex pharmaceutical wastewater is still a difficult and hot topic in water treatment at home and abroad. At present, pharmaceutical wastewater is a more difficult type of wastewater to be treated with a single treatment method, which is often difficult to handle by a combination process.
Pharmaceutical wastewater mainly contains the following characteristics:
1. Containing various organic substances such as sugars, steroids, organic pigments, strontium, plastids, alkaloids, cellulose, lignin, etc., with certain toxicity;
2. The wastewater is high in SS, contains a lot of sediment and dregs, and also contains a large amount of floating objects;
3, COD concentration is large, generally around 20,000, the concentration can be as high as 60000mg / L, between changes, and the amount of water changes;
4, high chroma, the general chroma is greater than 500 times.
Characteristics of pharmaceutical wastewater treatment process 1. The combination of different pretreatment methods and biochemical systems for different wastewaters, through the pretreatment system, to reduce the inhibition of some wastewater on microorganisms, and to improve the biodegradability of wastewater.
2. The process is mature and the system water is stable.
3, the design of water from a few tons / hour to five or six hundred tons / day, COD concentration can be as high as 100,000, the water reaches the national first-class emission standards.
