Pig farm wastewater comprehensive treatment device

Abstract

The invention discloses a pig farm wastewater comprehensive treatment device, which relates to the technical field of wastewater treatment. The pig farm wastewater comprehensive treatment device comprises a supporting mechanism and further comprises an executing mechanism, the executing mechanism comprises a smashing and liquid pumping assembly and a conveying and filtering assembly, and the smashing and liquid pumping assembly is used for pumping wastewater and scattering large solids in the wastewater to avoid pipeline blockage; the conveying and filtering assembly is used for filtering the waste water scattered and extracted by the smashing and liquid pumping assembly to realize primary solid-liquid separation and conveying solid with residual water to the control mechanism; the control mechanism comprises an extrusion assembly and a linkage assembly, the extrusion assembly is used for extruding water remaining in the solid, and the linkage assembly is used for discharging the extruded solid and controlling discharging of liquid obtained after sterilization and egg killing of the treatment mechanism, andthe treatment mechanism uses biogas as fuel to heat wastewater, kill bacteria and eggs. Safe treatment of pig farm wastewater is achieved through cooperation of the execution mechanism, the control mechanism and the treatment mechanism, and the sterilization effect is good.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a comprehensive treatment device for pig farm wastewater. Background technique [0002] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recycling and reuse, making full use of water resources. The composition of pig farm feces and wastewater is complex, which contains feces. Urine, soil, food residues, sawdust and other waste materials, while feces contain various parasite eggs, germs, etc. Improperly treated aquaculture wastewater will pollute the environment, and fecal skatole, hydrogen sulfide and other foul-smelling gases will pollute the environment. Air. If these improperly treated pig farm wastewater is used ecologically to irrigate farmland, germs and parasite eggs will remain on the stems and leaves of crops, and humans will be infected with various dis...
