本文针对水处理中对沉降污泥抽排泥中所存在的问题,通过系统论证研制了一种新型沉降污泥抽排封堵装置,本装置为国家新型专利技术,涉及到水处理工艺的一种装置,尤其是生活及工业污水沉降处理后污泥及沉淀物的抽排。依据同一物体在不同密度液体当中受到的浮力不同的原理,实现该封堵装置在液下进行上下浮动,进而实现对抽排管中各进液口进行自动打开或关闭,使其排泥效率显著提高,将沉降污泥抽排彻底。另外,该装置还具有运行可靠、结构简单、成本低廉、操作方便等优点,可广泛用于沉淀池排泥系统的新建和改造。
In this paper, aiming at the problems existed in the sludge disposal and sedimentation in the water treatment, a new type of drainage and sealing device for settling sludge was developed through systematic demonstration. The device is a national new type of patented technology and involves a water treatment process Plants, especially for pumping of sludge and sediment after settlement of domestic and industrial wastewater. According to the principle of different buoyancy of the same object in different density liquids, the sealing device can be floated up and down under the liquid, so as to realize the automatic opening or closing of each liquid inlet in the exhaust pipe to make the sludge discharging efficiency remarkably Improve, the sinking sludge pumping thoroughly. In addition, the device also has the advantages of reliable operation, simple structure, low cost, convenient operation and the like, and can be widely used in the construction and modification of the sedimentation tank sludge discharging system.
