Submersible mixer, also known as submersible thruster, is suitable for promoting and stirring sewage containing suspended solids, thin mud, industrial process liquid, etc. in the process of sewage treatment plant, creating water flow, strengthening stirring function, and preventing sludge precipitation. It is municipal and industrial sewage. Important equipment in the processing process: divided into mixing submersible mixers and submersible propelling mixers. Submersible mixers can be divided into mixing and mixing and low-speed push-flow. The original series of mixing and sub-series mixers are used for hand sewage treatment and the process of mixing liquids containing suspended solids in the same industry; low-speed push-flow series mixers are suitable for industrial and urban sewage treatment plants. Gas pools, which generate strong water flow with low tangential flow, can be used for circulation and creation of water flow in the stages of nitrification, denitrification and phosphorus removal, etc.
Precautions:
The selection of submersible mixers is a relatively complicated task. Whether the selection is correct or not directly affects the normal use of the equipment. Sure. According to the different process requirements of the sewage treatment plant, the flow rate of the mixer should be guaranteed to be between 0.15$ and 0.3m/s. If the flow rate is lower than 0.15m/s, the effect of push-flow mixing will not be achieved. If the flow rate exceeds 0.3m/s It will affect the process effect and cause waste. Therefore, before selecting the type, first determine the mud pool and biochemical pool where the submersible mixer is used; secondly, the parameters of the medium, such as: suspended solids content, viscosity, temperature, PH value; as well as the shape of the pool, water depth, etc. The matching power required by the mixer is determined according to the volume size, the density of the stirring liquid and the stirring depth, and one or more mixers are used according to the specific situation.
