Fixed compression device in waste water and waste gas

The utility model provides a waste water and waste gas fixing and compressing device which comprises a compressing tank, a bin cover is hinged to the front face of the compressing tank through a hinge, a PLC is fixedly connected to the front face of the bin cover, and extension rods are fixedly connected to the top and the bottom of an inner cavity of the bin cover. Through the arrangement of the compression tank, the bin cover, the PLC, the sleeve rod, the piston and the extension rod, the effect of pushing the piston to move downwards can be achieved along with the increase of the pressure at the upper end of the inner cavity of the compression tank, waste water located at the lower end of the inner cavity of the compression tank is extruded, and the pressure on the waste water can be increased along with the increase of the waste gas pressure at the upper end of the inner cavity of the compression tank; therefore, the wastewater needing to be filtered can be conveniently filtered under large pressure, and
