The net plate type internal inflow grille is novel high-efficiency grille decontamination equipment which combines dirt blocking and decontamination into a whole, and has the advantages of compact structure, small volume, high sediment blocking efficiency and reliable operation. More and more sewage treatment plants apply an internal inflow grid to the pretreatment stage. The grid dirt remover in the prior art has the defect that the upper limit of the overcurrent capacity cannot be changed in practical application. The overflow capacity of the grid dirt remover is designed according to the flow of the grid channel, and once the overflow capacity is fixed, the overflow capacity cannot be modified. However, in the actual use process, there may be a flow change such as an increase in the throughput, and the grid dirt remover cannot meet the increase in the throughput at this time, if the excess water is required to be increased, the grid dirt remover needs to be replaced by a grid dirt remover with a larger excess water capacity. This can result in increased cost of the retrofit equipment and production loss from downtime for the retrofit.
Under the premise of not modifying the grid channels, the grid plate type inner inlet grid in the prior art only increases the length of the grid plate type inner inlet grid if the water passing quantity is to be increased, but the length which can be increased is limited due to the limited strength of the grid plate frame.
