Detailed description of the invention

Fig. 1 is the sewage-treatment plant overall structure diagram of the utility model embodiment.

Fig. 2 is the preceding absorption tower cross-sectional structure schematic diagram of sewage-treatment plant of the utility model embodiment.

Specific embodiment

The utility model is described in detail below with reference to specific embodiments and the drawings.

Fig. 1 and Fig. 2 are please referred to, an embodiment of the present invention, a kind of sewage-treatment plant 10 comprising stir are shown Mix pond 20, adsorption tank 30, filtering ponds 40, sludge pump 50 and sludge-tank 60；The stirring pool 20 includes agitating device 21, dosing mouth 22 include motor 211, driver plate 212 and blender 213, the concentration funnel with concentration funnel 23, the agitating device 21 23 are located at 20 bottom of stirring pool, and outlet connecting pipe is connected with the sludge-tank 60 and connecting tube is equipped with the sludge pump 50；The adsorption tank 30 includes activated carbon adsorption room 31, ionic adsorption net 32 and demarcation plate 33, and the ionic adsorption net 32 is located at 31 top of activated carbon adsorption room, centre is separated with the demarcation plate 33；Sewage is flowed into from 20 lower side of stirring pool, By entering the adsorption tank 30 after the outflow of 20 top of stirring pool, is flowed out by 30 top-side of adsorption tank and enter the mistake Filter tank 40, the water handled are flowed out from 40 upper side of filtering ponds；The adsorption tank 30 and 40 inlet duct of filtering ponds dress There is gate valve, minimum point is mounted on blow-off line and hand-operated valve, by closing the entrance gate valve in pond, opens pond Blowdown valve is, it can be achieved that the adsorption tank 30 and 40 online backwashing of filtering ponds and blowdown.

Further, the driver plate 212 is circle, and the blender 213 is mounted on the driver plate 212.

Further, the blender 213 is cylindrical body, and surface is equipped with parallelogram stirring blade.

Further, the dosing mouth 22 is located at 20 top of stirring pool, and institute's adding medicine is flocculant.
