The utility model relates to sewage treatment technical field discloses a sewage treatment desilting device, including the treatment bin, the treatment bin top fixedly connected with the mixing bin, the treatment bin right -hand member bottom side fixedly connected with the discharge pipe, the treatment bin right -hand member top side fixedly connected with motor no.

The application relates to the technical field of soil remediation, and particularly discloses a heavy metal contaminated soil chemical leaching remediation device and a leaching remediation method. The heavy metal contaminated soil chemical leaching remediation device comprises a reaction tank provided with a containing cavity on the top side and a plurality of disturbance assemblies. A baffle plate is arranged in the containing cavity of the reaction tank, and the baffle plate forms a spiral flow channel in the containing cavity of the reaction tank. The disturbance assembly comprises a pipe body arranged in the spiral flow channel. A liquid driving assembly is arranged on the pipe body. A power assembly for driving the pipe body to move in the spiral flow channel is arranged on the baffle plate or the reaction tank. The heavy metal contaminated soil chemical leaching remediation device reduces energy consumption, reduces the input ratio of remediation reagents, and saves the cost of remediation reagents. The heavy metal contaminated soil chemical leaching remediation method forms multidimensional disturbance in the spiral flow channel, effectively breaks the laminar flow state of the mud, promotes the mixing of the reagents and the mud, and improves the uniformity and efficiency of the remediation reaction.

The utility model discloses sewage treatment flocculants throwing device in the technical field of throwing device, including: the treatment bin, the bottom of treatment bin is installed with the liquid outlet pipe, a plurality of liquid outlets are established to the surface of liquid outlet pipe, still include drive unit and installation unit, drive unit is used to drive liquid outlet pipe rotates, installation unit is used to install treatment bin in the top of sewage treatment pond, in the utility model, through rotating and inserting a liquid outlet pipe in the bottom of treatment bin, when using, the user installs treatment bin in the top of treatment pond through installation unit, then drives liquid outlet pipe to rotate through drive unit, can even spray flocculants in the inside of treatment bin to the inside of treatment pond, thereby can even make the sewage in the inside of treatment pond and flocculants contact, guarantees the effect of deposition.
