A biopharmaceutical wastewater treatment system and method

Abstract

A biopharmaceutical wastewater treatment system and method are disclosed. According to a biopharmaceutical wastewater treatment process, treatment tanks including an adjusting tank, a hydrolysis acidification tank, a first aeration tank, a second aeration tank, a sedimentation tank, an MBR tank, a membrane cleaning tank, a sludge tank and a high-concentration wastewater tank are arranged in order.The process includes following steps: transferring wastewater into the adjusting tank; transferring the wastewater in the adjusting tank into the hydrolysis acidification tank for acidification and decomposition; after the wastewater is reacted in the hydrolysis acidification tank, feeding the wastewater into the first aeration tank and the second aeration tank in order; then feeding the wastewater into the sedimentation tank to separate liquid supernatant and sludge through sedimentation, and feeding the separated liquid supernatant into the MBR tank; subjecting the liquid supernatant to blast aeration, filtration and exchange in the MBR tank to allow a product to reach a discharging standard; and recovering or discharging the water meeting the discharging standard. Biopharmaceutical wastewater can be effectively treated by the method to allow contents of COD, ammonia nitrogen and total phosphorous to meet the discharging standard, the cost is saved and service lifetime is long.

Description

technical field [0001] The invention relates to the field of biopharmaceuticals, in particular to a biopharmaceutical sewage treatment system and method. Background technique [0002] The process of purifying sewage in order to meet the water quality requirements for draining a bucket or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. [0003] In recent years, with the rapid development of the pharmaceutical industry, pharmaceutical wastewater has become one of the serious pollution sources. Pharmaceutical wastewater has complex components, many types of organic pollutants, high concentrations, high COD and BOD values ​​and large fluctuations. The BOD of wastewater The / COD value varies greatly, the concentration of suspended solids and ammonia nitrogen is high, the color is deep, and it contains difficult biodeg...

AI Technical Summary

Problems solved by technology

The main extraction and separation technology is the ethanol precipitation method, which uses more ethanol than other biopharmaceuticals. The ethanol will be recycled, mainly through distillation. The temperature of the wastewater directly discharged from the distillation tower is high, which will affect the sewage treatment system. The sludge causes impact, and the high temperature deactivates the sludge
