| 摘 要： | 针对机械加速澄清池回流缝堵塞、净化效果不佳等问题,通过采取改造排泥系统、增加搅拌桨的长度和外缘直径、加大回流缝等措施,有效改善了出水浊度和沉降比,提高了出水水质。新的排泥方式开辟了一条安全、可靠、节能的新途径,为同类改造提供了参考。

| Abstract: | Considering with the backflow blockage and unsatisfied purification in mechanical accelerated clarification tank,some measures,such as renovation of the sludge discharge system,increase the length of agitating propeller and exterior diameter,enlarge backflow were carried out.These could effectively improve effluent turbidity,sediment ratio and water quality.These methods would be safe,reliable and energy reducing for sludge discharge,and which could provide an example for same kind renovation. |
