WATER PURIFICATION TREATMENT SYSTEM

To provide a water purification treatment system with a novel structure.SOLUTION: A water purification treatment system includes a purification treatment unit which is installed in a water tank to be treated and performs purification treatment of water to be treated, and an air diffusion device which is installed in the treatment water tank and aerates the water to be treated stored in the water treatment tank. The air diffusion device communicates with a compressed air supply device by an air supply pipe and communicates with a cleaning liquid tank for supplying cleaning liquid for cleaning the cleaning processing unit and the air diffusion device by a cleaning liquid passage. A water purification system has control means for controlling switching between supply of compressed air from the compressed air supply device to the air diffusion device and supply of the cleaning liquid to the cleaning liquid passage when the water to be treated is filtered or when the cleaning unit and the air diffusion device are washed.SELECTED DRAWING: Figure 1 【課題】新規な構造の水浄化処理システムを提供すること【解決手段】被処理水槽内に設置され、被処理水を浄化処理する浄化処理ユニットと、前記被処理水槽内に設置され、前記被処理水槽内に貯留される被処理水を曝気する散気装置と、を備える水浄化処理システムであって、前記散気装置は、圧縮空気供給装置と送気管で連通されているとともに、前記浄化処理ユニット及び前記散気装置を洗浄する洗浄液を供給する洗浄液タンクと洗浄液流路で連通され、前記被処理水のろ過処理時又は、前記浄化処理ユニット及び前記散気装置の洗浄時に、前記圧縮空気供給装置から前記散気装置への圧縮空気の供給と前記洗浄液流路への前記洗浄液の供給の切替を制御する制御手段を備えることを特徴とする水浄化処理システム。【選択図】図１
