Abstract

The invention discloses a treatment method of high-concentration refractory ammonia-containing organic wastewater. The treatment method is characterized by comprising the following treatment steps of (1) homogenizing of quality and quantity of wastewater; (2) primary settling of wastewater; (3) denitrification of supernatant, and degrading of COD (chemical oxygen demand); (4) removal of COD, BOD (biochemical oxygen demand), ammonia and nitrogen out of primary treated water; (5) separation of mud and water of secondary mixing liquid; (6) removal of chroma of treated water, so as to reduce COD. The treatment method has the advantages that the number of treated buildings and structures is fewer, the number of equipment is fewer, the number of person operation and patrol check points is fewer, the operation and maintenance are simple and convenient, and the treatment efficiency of high-concentration refractory ammonia-containing organic wastewater is higher.

Description

[0001] Technical field: [0002] The invention relates to a wastewater treatment method, in particular to a treatment method for high-concentration refractory ammonia-containing organic wastewater. [0003] Background technique: [0004] Antibiotic wastewater is mainly produced in fermenter flushing, plate and frame filter press flushing, and crystallization mother liquor separation and extraction. The COD concentration in this type of wastewater is about 8000-15000mg / L, and the ammonia nitrogen concentration is about 500-1000mg / L. It has high COD and ammonia nitrogen concentrations, It is characterized by many refractory substances, strong toxicity, and large changes in water quality. It is a typical high-concentration refractory ammonia-containing organic wastewater. [0005] The current mainstream treatment process for antibiotic wastewater is "pretreatment + anaerobic biochemistry + aerobic biochemistry + advanced treatment". Because antibiotic fermentation wastewater is m...
