Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering, and is increasingly entering the daily lives of ordinary people. The upstream suppliers of the sewage treatment industry are mainly manufacturers of sewage treatment equipment and suppliers of sewage treatment chemicals, both of which are rapidly developing industries with good demand.

A drug discharge pipe 206 is fixedly installed on the bottom of the drug storage cylinder 208. A valve 207 is installed on the drug discharge pipe 206. The top of the treatment cylinder 1 is provided with an opening 4. The top plate 201 is located directly above the opening 4. The bottom end of the lower medicine tube 206 passes through the opening 4 and extends into the interior of the treatment barrel 1. An L-shaped plate 2011 is fixedly installed on the top of the treatment barrel 1. A motor 2010 is fixedly installed on the inner top wall of the L-shaped plate 2011. A transmission shaft 205 is fixedly connected to the motor 2010. The bottom end of the transmission shaft 205 passes through the opening 4 and extends into the interior of the treatment barrel 1. Several stirring rods 204 located in the treatment barrel 1 are evenly fixedly connected to the outside of the transmission shaft 205.

Since the large gear 305 is engaged with the two small gears 304, it drives the two rotating shafts 302 to rotate. At the same time, the stirring blades 303 on both sides rotate to stir the flocculant and sewage, and finally improve the mixing effect of the flocculant and sewage.
