Embodiment Construction
[0027] Such as figure 1 As shown, a sewage treatment system includes a grit well 1, an oxidation pond 2, a water collection well 3, a biological filter tower 4, a secondary sedimentation tank 5, an ecological filter bed 6, and a clean water tank 7, which are connected in sequence. The secondary settling tank 5 is connected to the collection well 3.
[0028] The water outlet of grit well 1 is higher than the water inlet of oxidation pond 2, the water outlet of oxidation pond 2 is higher than the water inlet of water collection well 3, the biological filter tower 4 is located above the secondary sedimentation tank 5, and the bottom of the secondary sedimentation tank 5 is high At the bottom of the collection well 3, the water outlet of the secondary settling tank 5 is higher than the bottom of the ecological filter bed 6, and the bottom of the ecological filter bed 6 is higher than the bottom of the clear water tank 7. In this system, the sewage flows through the sand well 1, oxid...

The invention discloses a sewage treatment system which comprises a silt basin, an oxidation pond, a water collecting well, a biological filter tower, a secondary sedimentation tank, an ecological filter bed and a clean water tank which are sequentially communicated along the sewage flow direction, wherein the water collecting well is communicated with the secondary sedimentation tank; the bottom of the water collecting well is provided with a lift pump; and the water collecting well is communicated with the biological filter tower through the lift pump. The sewage treatment system adjusts measures to local conditions, is suitable for the countryside with no professional managers and with irregular topography, has the advantages of lower manufacturing cost, lower operating cost, high dephosphorization / denitrification rate and favorable sewage purification effect. The phosphorus accumulating bacteria in the silt are sufficiently decomposed, thereby avoiding generating silt expansion and preventing secondary pollution.
Description
Technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically to a sewage treatment system. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have varying degrees of pollution. Pollution of urban and rural rivers has severely degraded their ecosystems. River water quality has deteriorated. Most of the river water bodies are seriously polluted and eutrophied. The water bodies become oxygen-poor, black and smelly, resulting in a severe environmental and ecological situation. Urban and rural domestic sewage is one of the main pollution sources of the water environment. [0003] At present, the sewage treatment system used in urban and rural areas has high process cost, high energy consumption, high secondary pollution, high cost of automatic control, and cumbersome operation. Summary of th...
