The utility model relates to a catchment trough of a pulse clarifier, which comprises an inverted trapezoidal catchment trough body with an inverted cross section. Several scum collecting troughs are arranged along the longitudinal interval of the upper and left sides of the catchment body, and several clarifying water collecting holes are arranged along the longitudinal symmetry of the lower and left sides of the catchment body, and a drainage trough is arranged at the bottom of the catchment body. The hole is characterized in that the distance between the bottom elevation of the scum collecting groove and the top elevation of the clarifying water collecting groove is 75 100 mm. Beneficial effect: The utility model can reduce the thickness of the dead water layer on the surface of the pulse clarifier as much as possible, ensure that the surface water is in a living state, optimize and improve its hydraulic conditions, fundamentally avoid and prevent the breeding of chironomid larvae and other biological phenomena, so as to keep the water surface of the clarifier, the inclined pipe surface, the catchment tank and the whole room in a clean state all the time, improve the quality of the effluent water and guarantee it. Drinking water is safe and can reduce the cost of operation, maintenance and management.

脉冲澄清池的集水槽
本技术属于生活饮用水处理领域,尤其涉及一种脉冲澄清池的集水槽。
技术介绍
沉淀(澄清)是常规净水处理工艺中的重要环节之一,常规沉淀(澄清)池主要有平流沉淀池、斜管板沉淀池、澄清池和气浮池等。澄清池包括机械搅拌澄清池、水利循环澄清池、脉冲澄清池等。脉冲澄清池是污泥层式絮凝澄清池,包括配水区、真空区、澄清水区和污泥浓缩区,由进水管、集水槽、排泥管、稳流板、泥层区、真空室、真空泵、自动真空破坏阀、配水管、加药管等部分组成。进水室上部的真空室连接有鼓风机、真空破坏阀,进水室下部的原水配水室连有原水进水管,原水配水室与澄清池的底部相连,澄清池内设有斜管及澄清水区,斜管下面为污泥层,在斜管上面的澄清水区设有集水槽。该池型将絮凝、澄清、浓缩、吸附功能建在一个构筑物内,和其它絮凝沉淀池相比,提高了净水效率,减少了占地面积。脉冲澄清池集水槽横断面为倒梯形,采用孔口浸没出流式集水,这种孔口集水方式对集水槽底部的水扰动较小,因此集水槽内水流平缓,流态稳定。由于澄清水收集孔的位置较低,导致澄清池表面经常存有一层深度120-150mm的死水层。另外,其浮渣收集槽口位置较 ...
