Description

A one-way valve and a mud discharge valve device with automatic adjustment of the size of the valve port

technical field

The invention belongs to the technical field of water treatment, and relates to rainwater collection, adjustment and utilization technology, in particular to a device for separation, control and treatment of rainwater collection sludge.

technical background

In the field of rainwater collection and treatment, rainwater storage tank technology has been widely used. At present, the operation of rainwater storage tanks at home and abroad is mainly to reduce flood peak waterlogging and relieve the pressure of sewage treatment plants to receive sewage. Part of the rainwater is collected during the rainfall period, and the collected rainwater is emptied soon after the rainstorm, and then the sludge at the bottom of the storage tank is removed. If the stored rainwater is stored for a long time, a large amount of organic waste accumulated at the bottom of the storage tank will rot and ferment, seriously polluting the water quality, which will turn the rainwater black and stinky, and excessive bacteria will cause the rainwater stored in the storage tank to be unable to be stored and utilized for a long time . In order to solve the problem of sludge polluting water quality, removing the deposited sludge in the water storage state is the most fundamental method to solve the problem that rainwater cannot be stored and utilized for a long time. Objectively, it is necessary to develop a sludge discharge valve device with automatic adjustment of the valve port size to effectively discharge sludge , retain rainwater.
