The utility model discloses a solid-liquid separation device for waste liquid treatment, which comprises a separation box, a water inlet pipe and a slag discharge pipe are respectively arranged on two sides of the top of the separation box, a blow-off pipe is arranged on the side wall of the bottom of the separation box, and a spiral net blade shaft is arranged in the separation box. And the top end of the spiral net blade shaft penetrates through the separation box and is connected with a driving motor. According to the utility model, waste liquid is guided into the separation box through the water inlet pipe, particulate matters in waste water are blocked and filtered layer by layer through the spiral net blade shaft, so that the particulate matters are retained on the spiral net blade shaft, water flows downwards under the action of gravity, enters the flow gathering cover through the filter holes and flows into the filter cartridge in the flow gathering cover, and the waste water is finely filtered throug
