德国某污水厂出水中有机微污染物的深度去除中试

Pilot Test on Advanced Removal of Organic Micro-pollutants from Effluent of a Wastewater Treatment Plant in Germany

德国某污水处理厂采用一套可移动的水服务设备Actiflo■Carb去除出水中的有机微污染物,该设备由粉末活性炭池和高效沉淀池(Actiflo■)组成,所用粉末活性炭为雅克比公司生产的Aquasorb MP23。选取24种有机微污染物作为目标去除对象,在4种不同的工况条件下进行中试。结果显示,大部分有机微污染物在15 g/m3的粉末活性炭投加量下,就可以达到60%以上的去除率;当粉末活性炭投加量为50 g/m3时,去除率可超过80%;对卡巴咪嗪(抗痫剂)和美托洛尔(β阻断剂)的去除率最高,平均去除率分别可达到93%和97%。中试结果表明,Actiflo■Carb可有效去除生物处理工艺出水中的有机微污染物。

Organic micro-pollutants in the effluent of a wastewater treatment plant were removed by Actiflo■Carb,a mobile water service equipment in Germany.Actiflo■Carb consisted of a powdered activated carbon(PAC)tank and a ballasted clarification tank Actiflo■,and the selected PAC was Aquasorb MP23 from Jacobi.Twenty-four kinds of organic micro-pollutants were selected and treated in the pilot test with four different operational conditions.The removal efficiency of most organic micropollutants could reach more than 60%when the PAC dosage was 15 g/m3.When the PAC dosage increased to 50 g/m3,the removal efficiency could exceed 80%.Among all the organic micro-pollutants,carbamazepine and metoprolol presented the highest removal efficiencies of 93%and 97%,respectively.Therefore,organic micro-pollutants in effluent from biological treatment process can be effectively removed by Actiflo■Carb.
