Surface control line monitor, the inner cavity between the liquid surface and the surface of the inner cavity is equipped with activated carbon reaction ball, the upper part of the reaction ball is impervious to water, and the lower part is a mesh outlet, which is filled with granular activated carbon. The volume of granular activated carbon accounts for 15%-98% of the volume of the reaction sphere. The mixture of ozone and sewage enters the reaction sphere from the inlet of the top of the inner shell to react, and flows out through the mesh outlet of the lower part of the reaction sphere, and the inner cavity. The water body is mixed, and the bottom of the inner cavity is provided with a loop water inlet to enter the outer cavity, and the outer casing is provided with a loop water pump to connect the outer chamber and the water inlet, and the sewage entering the outer chamber is pumped again into the activated carbon. In the reaction ball, the loop is performed in this way; a casing drain pipe is opened at the bottom of the outer cavity and communicates with the drain pipe opened at the bottom of the inner cavity for discharging the residual sludge, and the inner casing is further provided with water for reaction. The water outlet of the outer casing and a plurality of manholes for maintenance are discharged. The sewage treatment system apparatus according to claim 1, wherein the filter tank comprises a casing, and the filter tank is partitioned by an internal partition into two upper and lower chambers, an upper chamber and a lower chamber. Separately equipped with a plurality of vertical filter columns, each of which contains two or more kinds of particulate adsorbents which are naturally layered, including particle adsorbed sand and hybrid charged adsorbent made of sludge, in the filter tank The top end of the body is provided with a water inlet and a pressurized pipe, and the pressurized pipe is connected with a pressure pump, and a plurality of water pipes respectively opening at both ends of the upper chamber and the lower chamber are arranged outside the tank body to realize the filtered liquid The upper chamber flows to the lower chamber, and the upper side of the upper and lower chambers respectively have a sealing plate at the upper side and a lower water hole plate at the lower side, and the two ends of each vertical filter column are fixedly fixed to the sealing plate and the lower water hole plate. The vertical filter column has a plurality of side water outlets at the lower part of the side wall, a lower water outlet at the bottom, a total water outlet and a waste discharge port at the bottom of the lower chamber, and a bottom side wall of the upper chamber and the lower chamber. There is an exhaust duct, and the side wall of the filter tank is also There are several individual holes, and there are several support brackets on the outside of the side wall. A sewage treatment method for sludge quenching by using the sewage treatment system equipment described in claim 1 is characterized in that the method comprises the following steps: 1) sewage filtration: sewage enters through a sewage filtration device and enters Solid-liquid separation device; 2) Solid-liquid separation and preliminary decomposition of microorganisms and water: solid-liquid separation and preliminary decomposition of microorganisms and water in a solid-liquid separation device; 3) Liquid collection: treatment by solid-liquid separation device The sewage is recovered by the mist water collecting device and sent to the gas-water mixer. 4) Ozone treatment: the ozone generator is connected with the gas-water mixer, and the generated ozone is transported to the gas-water mixer and solidified. The sewage treated by the liquid separation device is mixed, and then the gas water is mixed The mixture is transported to the ozone-water reactor for reaction; 5) sludge treatment: in the above step, the sludge after the sewage treatment is converted into an adsorbent and a hybrid charge adsorbent by the sludge treatment system equipment, and is applied to the combined filtration. 6) composite filtration: the composite filtration device comprises a connected reverse activated carbon filter tower and a plurality of sets of filter tanks, and the water treated by the ozone-water reactor enters the composite filter device for deep treatment; 7) ultraviolet treatment: after compounding The water treated by the filtering device enters the reservoir, and is sent to the ultraviolet water processor, and is discharged after being irradiated by ultraviolet rays in the cavity of the ultraviolet water processor.
