摘要
利用微涡旋控制理论对南方某水厂传统絮凝网格进行了强化絮凝改造。运行结果表明,基于对剪切力与粘性力控制的强化絮凝网格处理微污染水源水具有一定优势:絮凝能耗小,出水矾花密实(分形系数大),矾花粒径大,对应的沉后水浊度降低0.1～0.3 NTU,沉后水、砂滤水藻类和有机物的去除率分别增加2％～5％。
The conventional grid at a waterworks in south China was reconstructed by enhanced
flocculation based on the micro-vortex control theory. The results show that flocculation-enhanced grid
improves the control of shear and viscosity forces, so it has some advantages to treat slightly polluted raw
water compared with the conventional one. The energy demands for flocculation decrease, the formed
flocs become denser (means fractal dimension is larger) and floc size grows larger. The turbidity of the
settled water goes down for 0.1-0. 3 NTU and the algae and organic substances removals of the settled
water and filtrated water increase by 2% - 5%.
