Abstract

The invention discloses an efficient treatment system and a treatment method for organic wastewater of bulk drug production in the pharmaceutical industry. The system comprises a high-concentration wastewater pretreatment unit, a triple effect evaporation unit, a biochemical treatment unit, a sludge pressure filtration unit and an activated carbon filtration deep treatment unit. By introduction ofa series of treatment means such as iron carbon reduction, catalytic oxidation, coagulation air floatation, triple effect evaporation, biochemical reaction and the like into the unit system, physicochemical treatment and biochemical treatment are combined together, removal efficiency of pollutants is increased, and the pollutants such as COD (chemical oxygen demand), ammonia nitrogen, SS (suspended solids) and the like in the wastewater are effectively degraded.

Description

technical field

[0001] The invention belongs to a high-efficiency treatment system for organic waste water produced by bulk medicine in the pharmaceutical industry, and in particular relates to an organic matter degradation treatment system and a treatment method for high-concentration organic waste water. Background technique

[0002] The general characteristics of high-concentration organic wastewater are complex components, COD, ammonia nitrogen, SS, high salt content, low B / C, and toxic substances. The organic substances in wastewater are mostly aromatic compounds and heterocyclic compounds, which have comprehensive biodegradability Poor characteristics, belongs to difficult to treat organic wastewater. The production of raw materials in wastewater is mainly chemical synthesis, mainly including the wastewater discharged from the research and development workshop of raw materials. The composition of the wastewater is relatively complex, with many intermediate products, hi...
