Pressure water distributing device

The utility model discloses a pressure water distributing device belonging to the range of sewage treating unit. A water inlet pipe is installed in the middle on the bottom of the pressure water distributing box, which is regularly or irregularly surrounded by pressure water outlet joints and connected by a pressure distributing pipe and a multidirectional distributing water head. The multidirectional distributing water head is inserted into the sludge blanket at the bottom of the pool to make the influent water current speed at the bottom of the pool to be faster than the gravity influent water current speed at the bottom of the pool. Therefore, the water at the bottom of the pool is more symmetrical and the current speed at the bottom of the pool is increased, forming a necessary current speed to prevent and stir the sludge and making the sludge blanket be stirred and lifted so as to make the sludge uneasy to be stored at the bottom of the pool; meanwhile, the sludge clogging on the top, lateral and bottom of the pressure water distributing device can be avoided. The pressure water distributing device is good for the mixing contact of the raw water and the sludge formed by the hydrolysis of acidification bacteria, oxygen-facultative bacteria and anaerobic bacteria, improving the adsorption, oxidation and degradation for the organic contaminant in the water; therefore, the pressure water distributing device improves the removal efficiency of whole sewage treatment, which is good for forming the particle sludge and the elution of the aging sludge and achieved good effect of applying in the sewage treatment and the recycle of the waste water project.
