专利汇可以提供SEWAGE TREATMENT PLANT专利检索,专利查询,专利分析的服务。并且Sewage treatment plant receiving an incoming stream of sewage from a sewerage system (2) subject to sudden influxes or storm surges includes a dynamic separator (6) adapted to effect separation of the incoming stream of sewage into a first fraction having a high water content and a low sludge content and a second fraction having a high sludge content and low water content. The first fraction is discharged to effluent treatment plant (36) with sudden influxes being temporarily accumulated in a storm chamber (30) and tank (32). The bulk of the sludge content is carried in the second fraction and removed in screening and degritting apparatus (18). As a result, odours associated with putrescent material in the sludge are largely confined to the dynamic separator (6) and the screening and degritting apparatus (18), which may be roofed over. Additionally, since the relatively clear water of the first fraction may be temporarily accumulated in the storm chamber and tank (30, 32) without producing marked odours, and discharged at a controlled rate, the effluent treatment plant (36) may be sized to a capacity appropriate to accommodate normal sewage flow rather than to accommodate sudden influxes or storm surges, with a consequent saving in capital, and operating costs. One or more additional dynamic separators may be positioned in parallel with the one dynamic separator to accommodate sudden influxes or storm surges.,下面是SEWAGE TREATMENT PLANT专利的具体信息内容。
