滦河原水2-MIB处理措施研究

Research on 2-MIB treatment of Luanhe River raw water

以滦河高藻期原水为研究对象,在2-MIB暴发的背景下模拟滦河水经由上游预氧化后流入塘沽某水厂,投加活性炭再进行强化混凝试验,分析处理措施对2-MIB的去除效果。试验表明:向原水中投加氧化剂与活性炭联用并非处理2-MIB的最佳技术,单独投加活性炭对2-MIB的吸附效果显著,最高去除率可达到近80%,能够有效去除水中嗅味物质。

Taking Luanhe River raw water in high algae period as a case,under the simulated condition of 2-MIB outbreak when the Luanhe River water flew into a waterworks in Tanggu after preoxidation at upstream,an enhanced coagulation test after adding activated carbon was carried out and the removal effect of 2-MIB was analyzed.The results showed that the combination dosing of oxidant and activated carbon in raw water was not the optimal treatment technology of 2-MIB.The single addition of activated carbon had significant adsorption effect on 2-MIB,and the highest removal rate could reach nearly 80%,and effectively remove the odor substances in water.
