Air stirring device: connected with a blower through a perforated pipe, and air is introduced into the perforated pipe by the blower for stirring. The strength of air mixing device is generally about 2m3. The air stirring device has a good effect, and can precipitate suspended solids in textile water. It is a common stirring method in industrial wastewater treatment, but it is easy to corrode, volatile substances escape into the air, and the operation cost is high.
Mechanical stirring device: it is a common method to disperse gas, liquid or solid particles in liquid by rotating the stirrer in the stirring tank. Mechanical stirring clarifier is a collection of mixing, flocculation and sedimentation. Mixing is the operation of mixing materials in a certain way to make them flow circularly, so as to make the materials mix evenly or accelerate the physical and chemical process. It is an operation in which two or more substances help each other and disperse in the flow. Mechanical mixing equipment includes paddle type, propulsion type and vortex type.
Forced circulation of water pump: the regulating tank is equipped with perforated pipe, which is connected with the water pipe of water pump. It is simple and easy to mix with pressurized water, but it consumes more electricity.
Hydraulic mixing of differential flow: it is not recommended to use perforated diversion groove to distribute water for homogenization. Although it does not require energy consumption, the homogenization effect is not stable enough, and the building structure is complex, and the bottom of the pool is easy to settle mud.
