摘要
水体富营养化对城市水环境构成了严重威胁,是当今世界性的水污染治理难题。加强城市污水的处理,提高城市污水处理厂出水的氮、磷指标,控制氮、磷等营养物质进入水体,是解决水体富营养化的重要途径。ECOSUNIDE工艺通过改变进水方式,提高活性污泥浓度,创造出有利于硝化菌和聚磷菌生长的环境,实现了短时高效脱氮除磷,并在临沂市污水处理厂的改造中得到成功应用。
As a global and difficult problem in controlling water pollution, water eutrophication can pose a threat to urban water environment. It is the critical solution for water eutrophication to strengthen municipal wastewater treatment, improve the effluent quality and restrain nutrient from waters. ECOSUNIDE could carry out a high sludge concentration as well as a high efficient nutrient removal in short time and create a favorable environment for the nitrifier and phosphate-accumulati bacteria by altering influent mode. This technology has been successfully applied in the reconstruction of Linyi sewage plant.
