Deep treatment system for bio-pharmaceutical organic wastewater

Abstract

The invention relates to a deep treatment system for organic wastewater of bio-pharmaceutical industry. The deep treatment system comprises an adjusting tank, a sedimentation tank, an electric flotation device, an advanced catalytic oxidation tower, an anaerobic membrane bed-aerated biofilter and a discharge pipe connected in turn, wherein the adjusting tank comprises a submerged stirrer; the electric flotation device comprises an electrode group; the electrode group is arranged at the bottom of the tank inner cavity and comprises a base, negative and positive electrode boards and a connection lead screw, the positive electrode board is an insoluble electrode board such as an iridium-coated titanium or ruthenium-coated titanium positive electrode board, and the negative electrode board adopts stainless steel graphite; the advanced catalytic oxidation tower is equipped with an ozone generator and is subjected to ultraviolet radiation; and the anaerobic membrane bed-aerated biofilter is equipped with an anaerobic tank, an aerobic tank and an aeration system. By using the deep treatment system for organic wastewater provided by the invention, the electrochemical treatment, filtration and biological degradation are integrated, organic matters and ammonia nitrogen in wastewater are more effectively removed, the performance-to-price ratio is high, the operation is simple, no toxic or harm action to the subsequent treatment is generated and secondary pollution can be effectively avoided.

Description

technical field [0001] The invention relates to a wastewater treatment system, in particular to a biopharmaceutical organic wastewater advanced treatment system. Background technique [0002] With the rise of the biopharmaceutical industry in recent years, the wastewater produced by the industry has a very bad impact on the environment, and a large amount of wastewater needs to be treated urgently. Biopharmaceutical wastewater has the characteristics of complex material composition and high content of dissolved organic matter. Because this type of wastewater is difficult to degrade and contains microbial inhibition, it not only has high ecological toxicity, but also nitrogen is easily discharged into the water body by nitrosation, which is extremely harmful to the environment. [0003] The treatment of biopharmaceutical wastewater in China usually adopts mixed and intensive biochemical methods. This type of conventional pharmaceutical wastewater treatment process has negli...
