Description
Technical Field
The invention relates to the field of environmental pollution treatment, in particular to a double-helix sedimentation tank suitable for removing surface runoff suspended matters in rural areas.
Background
In recent years, China pays more and more attention to environmental protection, continues to exert force on water resource protection, and solves point source pollution of industrial wastewater, urban domestic sewage and the like to a certain extent. However, due to the extensive living style and water use knowledge in rural areas, the water environment load is increasingly aggravated, and the corresponding environmental facilities are constructed laggard, so that the rural water environment is rapidly worsened, and the small-city water-stabilized environment eutrophication characterized by the enrichment of organic matters, nitrogen and phosphorus is in a spreading trend. Runoff pollution is a big factor of rural non-point source pollution, and the main sources of the runoff pollution are rural domestic sewage, rural solid waste, farmland pesticides and fertilizers, water and soil loss and the like. The current research mainly focuses on the research of runoff water quality in urban areas and surface runoff of rural farmlands, but the research on the runoff pollution control in typical village residential areas is less. At present, surface runoff treatment in most rural areas is relatively lacked, and the existing method is mainly used for treating rural surface runoff wastewater by constructing a small wastewater treatment station. Most of small-sized wastewater treatment stations mainly collect surface runoff by building pipelines or ditches, treat wastewater by certain processes such as sedimentation tanks, artificial wetlands, oxidation ponds and the like, and finally discharge the treated wastewater, thereby reducing the pollution of pollutants in the surface runoff on the environment. The sedimentation tank is widely applied to rural surface runoff wastewater treatment processes, but most of the existing sedimentation tanks are low in wastewater treatment efficiency.
Chinese patent CN201320005376.2 discloses a high-efficiency vertical flow inclined plate sedimentation tank, wherein a central cylinder, a reaction zone and inclined plate packing are arranged in the middle of a tank body, and raw water to be treated is added with a flocculating agent and then is discharged through the central cylinder, the reaction zone and the inclined plate packing. The invention can enhance the flocculation capability of suspended matters in raw water and promote the flocculation precipitation of the suspended matters. However, the efficiency of treating raw water is relatively low because the flow velocity of water cannot be too large because the inclined plate is mainly used for intercepting and settling suspended matters in water.
Chinese patent CN201420526214.8 discloses a vertical inclined tube sedimentation tank, which mainly comprises a central draft tube, a conical reflection plate, inclined tube seasonings, an overflow weir, etc. inside the cylinder, a flocculation settling layer is formed between the conical reflection plate and the inclined tube filler to intercept light suspended matters in water, and large suspended matters are intercepted by the inclined tube filler. It can effectively remove suspended matters in raw water, thereby achieving the purpose of purifying water quality. However, because the suspended matters in the raw water are removed mainly by using gravity and inclined plate packing, the flow of the introduced raw water cannot be too large, and the efficiency of treating the raw water is lower.
Chinese patent CN201520801997.0 discloses a hydrocyclone which mainly comprises a cylinder, a cone, a feed inlet tangent to the upper part of the cylinder, an overflow outlet arranged at the top of the cylinder, etc. The hydrocyclone mainly utilizes the structure of the hydrocyclone to lead the raw water to be treated to rotate in the hydrocyclone, thereby leading the suspended matters to be concentrated on the inner wall surface of the hydrocyclone under the action of centrifugal force and to slide down under the action of gravity to be discharged from a sand settling port at the bottom, and leading the clean water containing less suspended matters to be discharged from an overflow port inserted in the center of the hydrocyclone. But it is less effective in separating particulate matter having a density not much different from that of water because it mainly separates suspended matter in wastewater to be treated using centrifugal force.

The sewage treatment process of the double-helix sedimentation tank during working comprises the following steps:
sewage enters the sedimentation tank from the water inlet pipe 1 and enters the central cyclone 8 along the cyclone water inlet pipe 7. Since the sewage enters the central cyclone 8 from a tangential direction of the wall surface of the central cyclone 8, the sewage is rotated inside the central cyclone 8. The generated centrifugal force destabilizes and separates suspended matters in the sewage. The denser suspension will accumulate on the inner sidewall surface of the central cyclone 8 due to centrifugal force to form a concentrate, which flows down the sidewall. The less dense suspension will form a clear liquid which flows upwards through the overflow pipe 5 of the cyclone. The clear liquid flowing out of the overflow pipe 5 of the cyclone enters the central guide cylinder 9, flows out from the bottom of the central guide cylinder 9 downwards and then flows upwards. The flow velocity of the water flow in the central guide cylinder 9 is slow, and suspended matters in the clear liquid can settle on the outer wall surface of the hydraulic restraint plate 10, and after accumulation, the suspended matters slide into a sludge concentration area at the bottom of the sedimentation tank body 15 and are discharged by a sludge discharge pipe 12. The concentrated solution formed after the concentration of the suspended matters with higher density in the central cyclone 8 flows into the rotational flow fluid director 13 along the inner wall surface of the central cyclone 8 and flows out from the outlet 17 of the diversion trench, and the direction of the outlet 17 of the diversion trench and the tangential direction of the wall surface of the rotational flow fluid director 13 form a certain angle, so that the concentrated solution can rotate after flowing to the hydraulic restraint plate 10, and the suspended matters are gathered on the inner wall surface of the hydraulic restraint plate 10, slide down and are discharged through a sludge discharge pipe. The supernatant in the sludge concentration zone is converged with the effluent flow of the central guide cylinder 9, slowly flows upwards along the tank body and enters the inclined plate sedimentation zone. Through the effect of the inclined plate, finer suspended matters are intercepted and settled to the bottom of the sedimentation tank body 15 to be discharged, and water flow continuously flows upwards to the overflow groove 3 through the dovetail-shaped overflow weir 2 and is discharged through the water outlet 16 at the bottom of the overflow groove 3. The top of the central guide cylinder 9 is not sealed, so that the water quality condition can be observed, and the medicament is put into the water according to actual needs to promote the precipitation of suspended matters.
It can be seen from the above sewage treatment process that the sedimentation tank is particularly suitable for removing the particles in rural surface runoff, but is also suitable for removing the particles in mining wastewater, paper mill wastewater and other wastewater, and can effectively remove suspended matters and particles in the wastewater.
