Embodiment 1

[0019] The pharmaceutical wastewater to be treated is divided into two parts, one part is high-concentration pharmaceutical wastewater, the treatment capacity is 75t / d, the salinity is 7500mg / L, the COD is 46380 mg / L, and the ammonia nitrogen is 334mg / L; the other part is low-salinity wastewater, which is treated The amount is 100t / d, the salinity is 3830mg / L, the COD is 3450mg / L, and the ammonia nitrogen is 256mg / L; in addition, the domestic sewage salinity is 2530mg / L, the COD is 2264mg / L, and the ammonia nitrogen is 154mg / L.

[0020] The processing steps and effects are as follows:

[0021] (1) High-concentration pharmaceutical wastewater is decomposed through multi-dimensional electrocatalytic oxidation and high-efficiency micro-electrolytic oxidation to decompose a large number of organic pollutants, reduce biological toxicity, and greatly remove COD. After treatment, the salinity is 5430 mg / L, COD is 12732 mg / L, and ammonia nitrogen is 245mg / L;

[0022] (2) Put the phar...

Abstract

The invention provides a high-concentration organic pharmaceutical wastewater treatment method. According to the high-concentration organic pharmaceutical wastewater treatment method provided by the invention, high-concentration process wastewater and low-concentration wastewater are subjected to quality division and flow division, the high-concentration process wastewater is subjected to multi-dimensional electrocatalytic oxidation and high-efficiency micro-electrolytic oxidation, after the biotoxicity and the COD (Chemical Oxygen Demand) are reduced, the high-concentration process wastewatercan enter a biochemical treatment system after being mixed with low-concentration pharmaceutical wastewater and domestic wastewater, and finally, the wastewater can be filtered through an MBR (Membrane Bioreactor) membrane module, so that the COD and ammonia nitrogen in the pharmaceutical wastewater can be effectively degraded, three-level standard in Comprehensive Wastewater Discharge Standard (GB8978-1996) is met, and the wastewater can be discharged by accessing to a wastewater pipe network; the high-concentration organic pharmaceutical wastewater treatment method is simple in operation, good in effluent quality and stable in running.

Description

technical field [0001] The invention relates to the field of waste water treatment equipment, in particular to a method for treating high-concentration organic pharmaceutical waste water. Background technique [0002] Pharmaceutical industry wastewater mainly includes four categories: antibiotic production wastewater, synthetic drug production wastewater, Chinese patent medicine production wastewater, and washing water and flushing wastewater in the production process of various preparations. Pharmaceutical industrial 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. [0003] At present, the development of my country's pharmaceutical industry is unbalanced. Although there are many enterprises, their scale is small. A considerable part of the production process has reached the internatio...
