- Abstract:
- According to the wastewater characteristics of poor biochemical property, high content of ammonia nitrogen, SS and difficult degradation of organic matter, the treatment process of hydrolysis acidification/five-stage Bardenpho/high efficiency sedimentation/denitrification deep bed filter/ozone catalytic oxidation was used as the main process to treat the wastewater of Wangchang industrial park in Yibin. The combination process had advantages of compact structure, intensive arrangement and strong impact load resistance. The biodegradability of wastewater was improved by hydrolysis acidification to ensure the subsequent secondary treatment and advanced treatment effect. The high efficiency sedimentation tank/denitrification deep bed filter had perfect performance for SS removal, deep denitrification and dephosphorization. The first stage design scale was 5 000 m3/d, the effluent quality of the project was better than the standard of Discharge Standard of Water Pollutants in Minjiang and Tuojiang River Basins of Sichuan Province (DB 51/2311-2016) and first level A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The direct operation cost of the project was 0.94 yuan/m3.
