Pigsty sewage treatment device

Technical Field

The utility model relates to the technical field of sewage treatment equipment, in particular to a piggery sewage treatment device.

Background

The large-scale pig farm adopts the colony house to breed, and the whole growth cycle of pig is in the colony house of breeding, and diet, drinking water and excrete excrement and urine in the colony house of breeding cause the breed environment in the colony house relatively poor, need regularly clean and wash out the colony house of breeding. Excrement and urine in the colony house and clean sewage leak into the excrement and urine dirty pond after passing through the excrement leakage board, and excrement and urine in the excrement and urine dirty pond can ferment and use as the fertilizer after, need the excrement and water separation, reduce the water content and just can help the fermentation, contain a large amount of bacteria in the sewage of separation, need the bactericidal treatment, still need filter the excrement and urine granule in the sewage. Generally, the bactericide is adopted to sterilize sewage, and residues and foams of the bactericide in the sewage are manually salvaged, so that the sewage is time-consuming and labor-consuming.

Chinese patent discloses a pig house culture sewage treatment plant (grant bulletin number CN 212954668U), including filtering ponds and filter components, the lifting cylinder in filtering ponds outside can drive filter components to reciprocate and overturn. Guide grooves are formed in the inner walls of the two sides of the filter tank. The filter assembly comprises a first filter plate and a second filter plate which are mutually hinged, sliding shafts are arranged outwards at two sides of the bottom of the first filter plate, and the sliding shafts are arranged in the guide grooves and move up and down along the guide grooves. The piston rod of the lifting cylinder is connected with a connecting rod, and the connecting rod is arranged in the guide groove in a penetrating way and hinged on the sliding shaft. The filter tank is hinged with a pair of rotating blocks along the front and rear ends of the inner walls of the two sides respectively, and the first filter plate or the second filter plate passes through the space between the pair of rotating blocks. The filter assembly stretches into the filter tank, the bactericide residues fall on the filter assembly, the lifting cylinder can drive the filter assembly to move upwards, the first filter plate and the second filter plate which are hinged with each other can realize overturning, and the filtered bactericide residues and foams can be discharged outwards. However, the device cannot separate the excrement from the sewage, the filtered sewage may be mixed with residues, repeated filtration cannot be performed, and the sterilization effect of the final sewage cannot be ensured.
