WASTEWATER PURIFICATION SYSTEM
摘要：
A unit for wastewater treatment is provided. The unit (1) comprises a free- standing pre-assembled module on legs (2), a water inlet (4) and a water outlet (5), located in opposite sides of the unit (1). A screening compartment (6), containing a sieve (7) and a level transmitter (8) is arranged in the unit, and a grit trap compartment (13), containing a horizontal screw conveyor (14), and an inclined screw conveyor (15) is arranged downstream the screening compartment (6). Plates (22) are placed in said grit trap compartment (13) to create a vertical slit (23) after which there is a dosing point (24) for the metal salts. A polymer dosing zone (25) is located just before the outlet (26) of the grit trap compartment (13). A baffle (27) creates a gap (28) at the bottom of said grit trap compartment (13) and a weir (29) creates a horizontal barrier from the bottom of said grit trap compartment (13) followed by a mixing cavity (30) with a polymer dosing point (25) and an outlet (26). A method for operating the unit (1) is also provided.
摘要（中）：

提供废水处理单位。 单元（1）包括位于单元（1）的相对侧的支脚（2），进水口（4）和出水口（5）上的独立的预组装模块。 在该单元中布置有包含筛（7）和液位变送器（8）的筛分室（6），以及包含水平螺旋输送机（14）和倾斜螺旋输送机（15）的砂粒捕集室（13） 15）布置在筛分室（6）的下游。 将板（22）放置在所述砂粒捕集器室（13）中以产生垂直狭缝（23），之后存在用于金属盐的计量点（24）。 聚合物配量区（25）位于砂粒捕集室（13）的出口（26）正好。 挡板（27）在所述砂粒捕集器室（13）的底部产生间隙（28），并且堰（29）从所述砂粒捕集器隔室（13）的底部产生水平屏障，随后是混合腔（30） ）和聚合物计量点（25）和出口（26）。 还提供了一种用于操作单元（1）的方法。
