二龙山水库是东辽河上游一座多功能大型水利工程。库内污染物的主要来源有:其上游辽源市直接排入的工业废水和生活污水,每年达1188万m~3,且绝大部分未经处理;农田施用的化肥、农药渗余质;渔业、水上交通及旅游业污染等。按国家地面水二类标准要求,超标项目仍然不少。二龙山水库做为饮用水源,其水质不能满足要求,应采取的主要对策是:建立水源保护管理机构,按水源保护要求,进行统一管理;制定《二龙山水库水源保护管理条例》,以法保护,以法治理;清理各种污染源,对其重点进行限期治理;搞好水源保护林建设,加强流域内水土保持综合治理;农田要推广使用高效低毒、残留期短的农药和化肥等。
Erlongshan Reservoir is a multifunctional large-scale water conservancy project in the upper reaches of the East Liaohe River. The main sources of pollutants in the reservoir are: the industrial waste water and domestic sewage directly discharged into the upstream of Liaoyuan City reaches 11.88 million m 3 per year, with the vast majority being untreated; fertilizer and pesticide seepage remediation applied to farmland; fishery , Water transport and tourism pollution. According to the requirements of the national surface water class II standards, there are still many projects that exceed the standard. Erlongshan Reservoir as a source of drinking water, the water quality can not meet the requirements, the main countermeasures should be taken: the establishment of water conservation management agencies, in accordance with the requirements of water source protection, unified management; formulate “Erlongshan reservoir water source protection and management regulations” Protect and rule by law; clean up all kinds of pollution sources and control their priorities within a time limit; improve the construction of water conservation forests and strengthen the comprehensive management of soil and water conservation in the basin; and promote the use of pesticides and fertilizers with high efficiency and low toxicity and short residual period in farmland.
