大生活用海水的厌氧生物处理过程研究

文章研究了大生活用海水厌氧生物处理过程中海水盐度、水温、有机负荷、水力停留时间等因素对污染物去除率的影响。结果表明，厌氧塘对大生活用海水中COD，TKN，NH3-N，TP的净化效果分别可以达到50％、30．4％、24．9％和22．5％。温度对厌氧塘的去除率有较大的影响，随着温度的上升，厌氧塘对污染物的去除率提高。厌氧塘能够经受一定盐度变化的冲击和有机负荷的冲击，其水力停留时间以10d为宜。在污水中海水比例为36％时，经过培养驯化，厌氧塘中的优势耐盐细菌以假单胞菌属、索氏甲烷杆菌属、硝酸盐还原菌、硫酸盐还原菌为主。

Studies on the Treatment of Domestic Seawater by Anaerobic Pond

The effect and influence factors of domestic seawater treatment by the anaerobic pond are studied in this paper The results show that the removal efficiency of COD, TKN, NH3 N and TP in anaerobic pond is 50%, 30 4%, 24 9% and 22 5%, respectively Temperature has great influence on the removal efficiency of contamination in anaerobic pond With the increase of temperature, the removal rate of contamination will be increased Anaerobic pond has resistance to salinity and organic loading impact The optimum HRT of anaerobic pond is 0 to 12 days The culture and domestication technology of dominant bacteria is also studied in the anaerobic pond The predominant bacterium in anaerobic pond consists of Pseudomonas, Methanobacterium soehngenii, nitrate reducing bacteria and sulfate reducing bacteria when wastewater contains 36 percent of seawater
