海南岛罗牛河水污染分析及微生物固定化处理

Water Pollution Analysis and Treatment by Immobilized Microorganism on Luoniu River in Hainan

于2004年5月至2005年4月对海南岛罗牛河水域水质进行了取样和初步评价分析,并对所采水样采用微生物固定化技术进行处理,探求综合治理罗牛河水质的有效方法.结果表明:罗牛河水质污染较为严重,其中,污染最严重的罗牛河上游地段污染检测指标分别为pH 8.01±0.01、总磷0.14±0.01 mg.L-1、总氮1.57±0.06.L-1、溶解氧2.20±0.04 mg.L-1、COD 29.29±0.44 mg.L-1、BOD 6.73±0.16 mg.L-1、粪大肠杆菌群9 955.31±14.85个.L-1,对照中华人民共和国国家标准地表水环境质量标准(GHZB1-1999),各指标均未达到Ⅲ类排放要求;采用固定化技术,混合接种黄单孢菌、硝化细菌和反硝化细菌,并对罗牛河上游罗牛山段水样进行处理,78 h后,污水各项污染指标先后达到Ⅱ类排放标准.采用固定化黄单孢菌、硝化细菌和反硝化细菌技术对罗牛河水污染进行综合治理是非常有效的途径之一.

A sampling survey and analysis for the water quality of Luoniu river water area Hainan island have been done between May 2004 and April 2005. And then immobilized microorganism was used to dispose all the samples in order to find out effective method to comprehensively cure the water-quality of Luoniu river. The result shows that the pollution of Luoniu river is serious, especially the upriver area of Luoniu river. Its pollution index were pH 8.01±0.01, Total P 0.14±0.01 mg·L^-1 ,Total N 1.57±0.06 mg·L^-1,Dissolved oxygen 2.20±0.04 mg·L^-1 ,COD 29.29±0.44 mg·L^-1 ,BOD 6.73±0.16 mg·L^-1,E.coli 9 955.31±14.85 个·mL^-1, which did not achieve the emission control regulations Ⅲ, compared with the GHZB1-1999; Mixed Xanthomonas,nitrifying bacteria and denitrifying bacteria were immobilized to dispose all the samples of the upriver area of Luoniu river. Approximately 78 hours later, the pollution index of Luoniu river achieve the emission control regulations Ⅲ. Therefore, the technology of immobilizing Xanthomonas,nitrifying bacteria and denitrifying bacteria is an effective method to comprehensively cure the pollution of Luoniu river.
