Storage of raw water, used to precipitate large sediment particles and other precipitable materials in the water. At the same time buffer the original water pipe in the water pressure instability caused by the impact of the water treatment system. (Such as water pressure is too low or too high caused by the reaction of the pressure sensing).

The new buried integrated sewage treatment equipment is a kind of treatment equipment designed and developed by our company, which integrates pressure dissolved oxygen, jet aeration, internal circulation fluidized bed, biofilm filtration and other sewage treatment technologies into one; it has the advantages of saving investment, saving land and low operation cost, and can realize fully automatic unattended. Using this equipment to treat urban sewage, its effluent quality can reach GB18918-2002 "urban sewage treatment plant pollutant discharge standards" level A discharge standards.
