摘要:- 針對(duì)宜賓市王場(chǎng)工業(yè)園廢水生化性較差、氨氮和SS含量較高、有機(jī)物難以降解的特點(diǎn)，采用水解酸化/五段Bardenpho/高效沉淀池/反硝化深床濾池/臭氧催化氧化工藝處理園區(qū)廢水，該組合工藝結(jié)構(gòu)緊湊、布置集約化、耐沖擊負(fù)荷。水解酸化提高了廢水可生化性，保證了后續(xù)二級(jí)處理和深度處理效果，高效沉淀池/反硝化深床濾池去除SS、深度脫氮和除磷效果十分理想。一期設(shè)計(jì)規(guī)模為5 000 m3/d，工程出水水質(zhì)優(yōu)于《四川省岷江、沱江流域水污染物排放標(biāo)準(zhǔn)》(DB 51/2311—2016)以及《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》（GB 18918—2002）一級(jí)A標(biāo)準(zhǔn)要求。本工程直接運(yùn)行成本為0.94元/m3。
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.
