The grating is made of glass fiber reinforced plastic materials, and the glass fiber reinforced plastic has good corrosion resistance and heat resistance.
Inputting the sewage to be treated into a first sedimentation tank for preliminary sedimentation. In this embodiment, sedimentation tank one is provided with a plurality ofly to divide into two sets ofly, and use simultaneously, draw before the fortune at needs carrying out mud, stop using one of them sedimentation tank, and draw the fortune to this group of sedimentation tank mud, after the mud operation industry of this group of sedimentation tank was accomplished, use this group of sedimentation tank to store sewage, and stop the use of another group of sedimentation tank, carry out mud to another group of sedimentation tank and draw the fortune next, draw and transport the completion back, use two sets of sedimentation tanks to deposit the operation simultaneously.
And inputting the sewage after the primary precipitation into a flocculation tank, and adding a flocculating agent into the flocculation tank for flocculation. The flocculating agent is aluminum sulfate. When the sewage reacts in the aeration tank, the PH of the sewage is adjusted to 7-8, and then the sewage is stirred. The sewage is flocculated in the flocculation tank to generate sludge, the sludge in the flocculation tank is discharged into the transfer sludge tank within a certain period I, and the sludge in the transfer sludge tank is fished out and transported away within a certain period II. Wherein the concentration of the flocculating agent is 5-8 ppm. In this embodiment, the amount of the flocculant is 6ppm, and the flocculant is added to flocculate the dead bacteria, colloids, algae, macromolecular organic substances originally contained in the water, and iron hydroxide colloids generated by oxidation of ozone into large particles. The sedimentation rate of suspended matters in the water body is accelerated through the flocculating agent, the flocculation time is prolonged, the working efficiency of subsequent treatment is improved, and meanwhile, the load of the subsequent treatment is reduced.
