Embodiment 1

[0061] A high-efficiency treatment system for the production of organic wastewater from raw materials in the pharmaceutical industry, including: a high-concentration wastewater pretreatment unit A, a three-effect evaporation unit B, a biochemical treatment unit C, a sludge filter press unit D, and an advanced treatment unit E for activated carbon filtration;

[0062] Wastewater enters from the high-concentration water collection adjustment tank of high-concentration wastewater pretreatment unit A, and is connected through pipelines. After being treated by iron-carbon reduction tank, catalytic oxidation tank and coagulation air flotation machine, the effluent flows to the intermediate pool by itself, and the slag flows into the sewage by itself. Mud concentration pool; according to the water quality of the intermediate pool, through the adjustment of the pipeline valve, it is connected to the three-effect evaporation equipment of the three-effect evaporation unit B and the low-co...

Embodiment 2

[0074] Experimental application example: high-efficiency treatment system for organic wastewater produced by raw materials in the pharmaceutical industry.

[0075] For a pharmaceutical company in the north, the discharge of high-concentration organic wastewater is about 50 t / d, and the discharge of low-concentration wastewater is about 150 t / d. The wastewater treatment station is established by using the treatment system of the present invention, and its design scale is 200m 3 / d, in which, after the high-concentration organic wastewater passes through the high-concentration wastewater pretreatment unit, dosing room, and three-effect evaporation unit, the combined low-concentration wastewater enters the biochemical treatment unit, the sludge filter press unit and the advanced treatment of activated carbon filtration Unit treatment, the final water quality is up to standard discharge, and the sludge is transported out by pressing and filtering.

[0076] The water quality indica...

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...
