摘要
河流污染不仅会破坏水环境,还会影响城市发展和人民生活质量.目前主要采用传统工艺改善河流水质,如曝气、生态浮岛和异位处理等,但传统工艺影响河流行洪,对水量有一定要求.以福建省漳州市某河流为例,采用"生态因子调控+功能性生态礁石净化+原位微生物调控"组合工艺,通过工程措施提升水质.结果表明,组合工艺应用后,河流溶解氧含量提升 47.4%,氨氮及总磷含量分别降低 63.5%和56.5%,水体指标稳定达到《地表水环境质量标准》(GB 3838-2002)的Ⅲ类水质要求.该组合工艺环境友好,可用于提升河流水质.
Abstract
River pollution not only damages the water environment,but also affects urban development and people's quality of life.At present,traditional processes are mainly used to improve river water quality,such as aeration,ecological floating islands,and ex-situ treatment,however,traditional processes affect river flooding and have certain requirements for water quantity.Taking a river in Zhangzhou city,Fujian province as an example,a combination process of"ecological factor regulation+functional ecological reef purification+in-situ microbial regulation"is adopted to improve water quality through engineering measures.The results show that after the application of the combined process,the dissolved oxygen content in the river increases by 47.4%,while the ammonia nitrogen and total phosphorus content decreases by 63.5%and 56.5%,respectively,and the water quality indicators stably meet the ClassⅢwater quality requirements of the Environmental Quality Standards for Surface Water(GB 3838-2002).This combination process is environmentally friendly and can be used to improve river water quality.
