Abstract

The invention relates to the field of industrial waste treatment, in particular to an industrial wastewater and waste gas treatment system. In a waste gas and wastewater treatment method according to the invention, treatment units carry out combined treatment, arriving at the advantages of high treatment efficiency, good process stability, wide range of application and the like; significant coordinated treatment effect is embodied in the deep treatment of pharmacy wastewater by the treatment units, and the wastewater treated meets the wastewater emission standards. The industrial wastewater and waste gas treatment system provides simultaneous treatment of waste gas and wastewater, saves energy, reduces consumption, and meets the modern environmental concepts.

Description

technical field [0001] The invention relates to the field of industrial waste treatment, in particular to an industrial waste water and waste gas treatment system. Background technique [0002] In recent years, with the development of industrial and agricultural production and the improvement of urban people's living standards, the discharge of industrial wastewater, waste gas, and urban sewage is increasing. The resulting environmental pollution has seriously affected environmental ecology and human health, especially The discharge of high-salt and high-concentration organic wastewater is becoming more and more serious, which is one of the important reasons for water environment pollution. The main ion contained in high-salt organic wastewater is Cl - , SO 4 2- 、Na + , Ca 2+ and other salts. High-concentration ions will inhibit and poison microorganisms, mainly manifested in: high salt concentration, high osmotic pressure, dehydration of microbial cells causing cell p...
