Problems solved by technology

Existing dredging devices generally use dredging pipes directly to absorb the sludge. The dredging takes a long time, and the long-term accumulation of sludge will cause serious dirt or scaling at the bottom of the foundation pool, resulting in incomplete dredging. Moreover, the main component of the sludge produced in the fecal sewage is poultry manure, and the sludge is directly dredged and discharged. The sewage in the sludge and large stones and other debris will be mixed in the sludge, which will affect the secondary utilization of the sludge. Therefore, In view of the above problems, a dredging device and dredging method for agricultural sewage stations are proposed

Abstract

The invention discloses a dredging device and dredging method for an agricultural pollution site. The dredging device comprises an agricultural pollution base pool, an agricultural pollution ditch and a dredging treatment module. The agricultural pollution ditch is arranged behind the agricultural pollution base pool, the inner side of the agricultural pollution base pool is provided with a sludge base backing plate, the left side of the agricultural pollution base pool is provided with a rolling module, a sludge accumulation module is arranged on the inner side of the agricultural pollution base pool, the dredging treatment module is arranged on the right side of the agricultural pollution base pool, a filter pressing module is arranged on the inner side of the dredging treatment module, and a filter pressing plate is arranged below the filter pressing module. Sludge at the side edge position of the sludge base backing plate is pushed to the center position of the sludge base backing plate through the sludge accumulation module, dredging treatment of the sludge is facilitated, the phenomena of serious scaling and smudginess caused by long-term accumulation of the sludge in the agricultural pollution base pool are avoided, the filter pressing plate descends under different conditions, different substances in the sludge are separated, excrement in the excrement sewage can be conveniently used as agricultural fertilizer for secondary utilization.

Description

technical field [0001] The invention relates to the technical field of sludge cleaning, in particular to a dredging device and a dredging method for agricultural sewage stations. Background technique [0002] The agricultural sewage station is the station for the treatment of agricultural sewage. Agricultural sewage refers to the sewage or liquid substances discharged during the process of crop cultivation, livestock breeding, and agricultural product processing, which affect human health and environmental quality. Near the farm, often set up The agricultural sewage station treats the sewage from the feedlot. The types of wastewater discharged from the livestock farm include: fecal wastewater, production sewage, domestic sewage and rainwater. When the agricultural sewage station stores agricultural sewage, sludge is often produced in the sewage, of which fecal wastewater The sludge in it can be used as agricultural fertilizer and has the effect of secondary utilization. Exi...
