The invention discloses a 
water pollution monitoring and treatment service 
mechanism based on 
the Internet of Things. The 
water pollution monitoring and treatment service mechanism comprises a machinebody, wherein a filtering cavity is formed in one end of the 
machine body; a grid is arranged in the filtering cavity; a 
flocculation cavity is formed in the 
machine body and located at one side of the filtering cavity; a sand setting area is arranged at the bottom of the 
flocculation cavity; a fixed seat is fixedly connected to the top of the 
machine body and is positioned above the flocculationcavity; a storage box is arranged at the top of the fixed seat; a 
sedimentation cavity is formed at one side of the 
flocculation cavity; a filter screen is arranged at the communicating position of the flocculation cavity and the 
sedimentation cavity; an anaerobic cavity is formed in one side of the 
sedimentation cavity; and two partition plates are fixedly connected to the inner wall of the anaerobic cavity. According to the 
water pollution monitoring and treatment service mechanism, a 
water quality detector is matched with a 
sewage treatment machine, so water 
pollution monitoring and treatment work can be effectively carried out; and effective and stable 
sewage treatment work can be realized through structural arrangement in the 
sewage treatment machine, and stable operation of a sewagetreatment 
system is guaranteed.
