Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with specific embodiments.

[0015] Table 1 shows the water quality indicators of wastewater discharged from a capsule, tablet, and granule Chinese patent medicine enterprise:

[0016] waste water type pH COD BOD NH3-N SS High concentration wastewater — ≤16000 ≤4500 ≤50 ≤1500 low concentration wastewater 6-9 ≤500 ≤250 ≤30 ≤250

[0017] The treatment process of the present invention is as follows: high-concentration wastewater first passes through the grid well to remove large impurities, then enters the primary sedimentation tank, removes most of the suspended matter, and then flows to the adjustment tank by itself, and the water quality in the adjustment tank is uniform; Coagulation and sedimentation tank Ⅰ, which controls the suspension of iron-carbon micro-electrolysis; the effluent of coagulation-sedimentation tank Ⅰ flows to iron-carbon micro-el...

Abstract

The invention discloses a Chinese patent medicine production wastewater treatment technology, and belongs to the technical field of wastewater treatment. The technology comprises the steps of (1) pretreatment, (2) coagulation precipitation treatment, (3) anaerobic treatment, (4) aerobic treatment, (5) filtering treatment, and (6) sludge treatment. Chinese patent medicine wastewater undergoes pretreatment, coagulation precipitation, anaerobic treatment, aerobic treatment and the like, so the chemical oxygen demand (COD), the biochemical oxygen demand (BOD), the concentration of solid suspension (SS) and the content of ammonia nitrogen (NH3-N) in the wastewater are greatly reduced, and the influences on the environment are reduced.

Description

technical field [0001] The invention relates to the treatment of wastewater in the field of pharmacy, in particular to a process for treating wastewater produced by Chinese patent medicines in capsules, tablets and granules. Background technique [0002] Wastewater from the Chinese patent medicine pharmaceutical industry is a type of high-concentration organic wastewater containing refractory substances and biotoxic substances. The domestic Chinese patent medicine pharmaceutical industry has a large amount of wastewater discharge and serious water pollution. The wastewater is characterized by complex components, high organic content, high toxicity, deep color and high salt content, especially poor biochemical properties, and intermittent discharge, which is difficult to treat industrial wastewater. With the development of my country's pharmaceutical industry, Chinese patent medicine pharmaceutical wastewater has gradually become one of the important sources of pollution. How...
