Embodiment 1
[0037] see figure 1 , 2 3. An underground high-efficiency energy-saving percolation water treatment device, comprising a water inlet pipe 21, a clean water outlet pipe, an aeration barrel and a filter tank, and a maintenance observation room is arranged on the side of the filter tank, and the aeration tank, filter tank and filter tank The tank maintenance and observation rooms are all buried, and the aeration tank, filter tank and filter tank maintenance and observation room are made of corrosion-resistant plastic.
[0038] There is a multi-layer filter material layer 23 inside the filter tank 2. The above-mentioned filter material is a multi-layer composite filter material composed of ores with different densities, different particle sizes, and different functions, and meets different water quality treatment requirements according to a certain ratio. There is a support filter plate 28 below the filter material, a pressure-relief plate 25 is arranged on the top of the filter ...
Embodiment 2
[0054] The difference from the single-cylinder filter structure in Embodiment 1 is that in this embodiment, multiple filter cylinders can be connected in parallel to form a multi-cylinder structure that meets different flow requirements while the aeration tank remains unchanged. The following four-cylinder Combined technical solutions for further explanation.
[0055] This multi-tank combined water treatment device includes four identical single tanks of Embodiment 1, and the four filter tanks are symmetrically connected with the aeration barrel, wherein every two single tanks are connected to the same maintenance observation room, and the four filter tanks are connected to the same maintenance observation room. The water inlet pipes of the filter tanks are each connected to an electric control valve, and the other end of the electric control valve is connected to the common water inlet pipe. The water level sensor heads at the upper ends of the backwash sewage pipes of the fou...
