As the front end of sewage treatment, the sewage blocking effect of the grid pond is very significant in practice, because once sewage blocking is not timely, the subsequent circulation of sewage among the treatment ponds is blocked, and thus the sewage treatment is stagnated. Aiming at improving the dirt blocking capacity of the grid pool, the prior method is to perform coarse grids with larger filtering intervals in the dirt blocking pool to block larger garbage, and then to perform small garbage blocking through fine grids with smaller filtering intervals. However, the garbage blocked by the sewage cannot be cleaned and discharged in time, so that the circulation of the sewage is affected, and part of the household garbage blocked by the sewage is extruded out of the grid due to overlarge water pressure, so that the household garbage flows to the next treatment pool.
Therefore, the invention aims to design the domestic sewage treatment equipment and the domestic sewage treatment method which can effectively and regularly clear and discharge the domestic garbage blocked by the coarse grille and the fine grille and can ensure that the garbage clear and discharge has enough convenience.
