Introduction to the results:

This system provides a set of economical, efficient and pollution-free treatment devices for new water quality purification technologies for reclaimed water landscape water bodies. By building a modified zeolite biological filter, a treatment system that combines the advantages of biology and modified zeolite, the water quality purification of the landscape water in the community can be realized, and nitrogen and dissolved pollutants that cannot be cured by current landscape polluted water treatment methods can be solved. problem.

The reclaimed water landscape water modified zeolite biological filter treatment system in the community includes a reclaimed water landscape pool, an inlet pump, an inlet water storage tank, a metering pump, a water volume adjustment pool, a modified zeolite filler area, a sedimentation pool, and an aeration machine. Its characteristics are: The contaminated sewage from the middle water landscape pool is pumped into the inlet water storage tank by the inlet pump. After being pumped into the water volume adjustment tank through the metering pump and its inlet pipe, it flows into the modified zeolite filler area from the perforated plate at the bottom, and fully contacts with the modified zeolite and its attached biomembrane to remove pollutants. Then it overflows out of the sedimentation tank into the outlet tank, and is discharged into the middle water landscape pool through the outlet pipe.

In the community water landscape water modified zeolite biological filter treatment system, the middle water landscape pool is connected with the inlet water storage tank through the inlet pipe by the inlet pump, and the metering pump is connected with the inlet water storage tank and the water volume adjustment pool through the inlet pipe. The bottom of the wall plate between the modified zeolite filler area and the water volume adjustment pool is connected with a perforated plate; the modified zeolite filler area is connected with the sedimentation tank and the outlet tank in turn, the sedimentation tank is lower than the modified zeolite filler area, and the outlet tank is lower than the sedimentation tank; Outlets at the bottom of the water regulation tank, the modified zeolite filler area, the sedimentation tank and the water outlet tank are connected with vent pipes.

The water inlet pipe of the water volume adjustment tank is connected to the side wall of the tank, and the water outlet pipe of the water outlet tank is connected to the side wall of the water outlet tank.

At least three aeration branch pipes are connected to the side wall of the modified zeolite filler area at regular intervals, and all the aeration branch pipes are connected in parallel to an aeration pipe and connected with the aerator.

Technical advantages:

In this device, the liquid level in the modified zeolite filler area is kept level with the surface of the modified zeolite. The sewage removes pollutants in the middle water landscape water through the good adsorption effect of the modified zeolite, ion exchange effect and biomembrane biological effect, and the effluent water quality reaches the water quality standard for Li Landscape Environment (GB/T 18921 -2002).

The modified zeolite filler area is a facultative environment, with dissolved oxygen (DO) maintained at about lmg/L and hydraulic retention time of about lh.

Application prospects:

The modified zeolite biological filter device used for polluted water bodies in the community can be connected to a computer through metering pumps, solenoid valves, controllers, etc., and can realize high-level device operation and water quality monitoring based on the water quality indicator values obtained by the water quality monitor. automation.
