The working process of the equipment is as follows:
the water pump pumps raw water into the water inlet mixer 2 at the front end of the shell 1, and then the raw water is fully mixed with flocculant injected by a proper amount through the flocculant injection port 3 on the water inlet mixer 2 in the water inlet mixer 2. After the mixed treatment water is passed through the porous or sieve-type horizontal water distributor 4 with the function of separating larger sundry fibers, when the water is provided with the water inlet baffle 91 and downwards extends into the water homogenizing and flow-assisting plate 8 and then flows into the cone sedimentation area 14 in a uniform manner, colloid and dispersed particles of suspended matters in the water are generated into floccules under the interaction of molecular force and are continuously collided and condensed in the sedimentation process, and the size and the quality of the floccules are continuously enlarged under the action of the slow-resistance mixed flow of the coagulation-assisting flow-assisting plate 10 in the cone sedimentation area 14 so as to accelerate sedimentation and promote solid-liquid separation and layering.

The special water-gas pressure backflushing device has the capability of fast and effective backflushing and recovering the treatment efficacy of equipment. Firstly, stopping water inflow and flocculant injection, opening the bottom quick-opening blow-down valve 17, and opening the backflushing water inflow control valve 23 and the backflushing compressed air control valve 24. Under the action of the pressure gas and water of the water-gas jet backflushing device 12, loosening gaps of the filter material of the combined filter layer 5 are increased, sediment adsorbed on the filter material is stripped and discharged along with water flow from the bottom quick-opening sewage discharge valve 17, and the equipment processing capacity is restored. When the new period of raw water treatment is entered, after the inflow water is diffused into the combined filter layer 54, the backflushing inflow water control valve 23 backflushes the compressed air control valve 24 and the side-stream sewage control valve 22. The dissolved air water generated by the water-air mixer 11 enters through the water-air jet backflushing device 12, so that residual flocculating mud and suspended matters are floated to the liquid level and lifted along with the water level, and the water is discharged through the side low-level floating foam side flow port 20, the drain 21 pipe and the side-flow drain control valve 22 after passing through the horizontal water discharge weir plate 18. And after meeting the requirements, entering a new processing period to normally operate.
