Problems solved by technology

The existing desanding work is usually carried out by manual observation, and then the desanding work is carried out by controlling the sand suction machine, which not only has a large deviation in the estimation of the deposited sediment in the grit chamber, but also requires manual control of the sand suction machine. It also requires the operator to monitor the working status of the sand suction machine and the removal of the sediment in the grit chamber, which is time-consuming and laborious. Moreover, due to the error of manual observation, the work and use of the grit chamber are affected, and the efficiency of sewage treatment is reduced.

Abstract

The invention discloses a grit removal device for a grit chamber. The grit removal device comprises a grit chamber main body, a grit discharge pump, an inductor and a motor, wherein one end of the grit discharge pump is arranged on the inner bottom surface of the grit chamber main body, the other end of the grit discharge pump is arranged on one side of the top end of the grit chamber main body, the inductor is arranged above the inner bottom surface of the grit chamber main body, the motor is connected with the grit discharge pump, and a PLC (Programmable Logic Controller) cabinet is connected with the inductor and the motor respectively through a data line. The grit removal device is simple in structure, convenient to install and free of manual operation errors in traditional grit removal work, the manual operations can be reduced, the labor cost can be lowered, the sewage treatment efficiency can be improved, and the service life of the grit chamber can be prolonged.

Description

[0001] technical field [0002] The invention relates to a sewage treatment device, in particular to a sand removal device for a grit chamber. Background technique [0003] Sewage treatment is the process of making sewage meet the water quality requirements for a certain water body to be discharged or reused, and to purify it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it has increasingly entered the daily life of ordinary people. [0004] Existing sewage treatment technologies are usually divided into primary, secondary and tertiary treatment. The primary treatment belongs to the pretreatment of the secondary treatment, which mainly removes the suspended solid pollutants in the sewage. Most of the physical treatment methods can only meet the requirements of the primary treatment. After primary treatment, BOD...
