无阀滤池进水分配箱自动停止进水装置早在七十年代初就由有关单位试制并应用于生产实际,国家标准图集中也已列入。但由于安装及水幕等原因,往往不能立即停止进水,造成滤池反冲洗时沉淀过的水继续随着反冲废水一道排入下水道,当反冲洗完成后又不能很快恢复进水,要靠滤池水箱水位慢慢升高,把破坏管口封住后才能恢复进水 The valveless filter water inlet distribution box automatically stops the water inlet device as early as in the early 1970s by the relevant units of trial production and applied to the actual production, the national standard map has also been included. However, due to installation and water curtains and other reasons, it is often not possible to immediately stop the inflow of water. As a result, the precipitated water in the backwash of the filter continues to be discharged into the sewer along with the recoil wastewater. When the backwashing is completed, the water cannot be quickly restored. The water level in the filter tank will rise slowly, and the damage to the nozzle can only be restored after entering the water.
