Description
Technical Field
The utility model relates to a sewage treatment technical field, concretely relates to pipe chute sedimentation tank structure.
Background
In sewage treatment plants, sedimentation tanks are used for sedimentation treatment of sewage. After sewage enters water and is filtered and subjected to biochemical reaction in a biochemical tank, the sewage enters a sedimentation tank again for sedimentation. In the sedimentation tank, be provided with the so-called pipe chute sedimentation tank of pipe chute in the sedimentation zone, utilize the parallel tube of slope or parallel conduit (usable honeycomb packs sometimes) to cut apart into a series of shallow layers sedimentation layer promptly in the sedimentation zone of advection formula or vertical flow formula sedimentation tank, sewage gets into the sedimentation tank from the pipe chute lower extreme during the processing, again from outside the sedimentation tank upper portion overflow hole overflow goes out the pond, and then make the precipitate in the sewage can rely on the effect of pipe chute to be stopped better and stay in the sedimentation tank, can improve the sedimentation effect better.
However, in the sedimentation tank, as the sewage is rich in nutrient sources such as nitrogen and phosphorus, a large amount of hairy algae can be bred at the water outlet at the upper end of the inclined tube under the irradiation of sunlight, and the water outlet efficiency of the inclined tube can be greatly influenced for a long time. Therefore, sewage plants generally need to be treated by manpower regularly, but algae can grow more firmly on the upper end of the inclined tube, the treatment efficiency is low, workers also have safety risks, and the working effluent of the sedimentation tank is influenced. Therefore, the artificial treatment effect is not ideal, and the algae may flow out of the sedimentation tank along with the effluent, thereby affecting the water treatment effect and the effluent quality.
In addition, CN109574383A discloses an efficient ecological algae-reducing system for a sedimentation tank, which comprises a rapid mixing tank weir, a coagulation reaction tank weir, a plug flow tank weir and an inclined tube sedimentation tank weir, wherein the bottoms of the rapid mixing tank weir, the coagulation reaction tank weir, the plug flow tank weir and the inclined tube sedimentation tank weir are sequentially communicated; the rapid mixing pond weir mouth is used for carrying out the rapid mixing with sewage and the medicament of adding for the first time, and the reaction tank weir mouth that thoughtlessly congeals is used for carrying out the intensive mixing flocculation with flocculating agent and sewage, and the plug flow pond weir mouth further carries out the flocculation, and the pipe chute sedimentation tank weir mouth deposits sewage, and the pipe chute sedimentation tank weir mouth includes a plurality of water catch basins, plants aquatic plant between two adjacent water catch basins, places the fish in the water catch basin.
In this current patent scheme, through planting the aquatic plant in the sedimentation tank, can consume the nutrient source in the sewage, avoid sunshine to shine the pipe orifice of pipe chute simultaneously, can avoid the pipe orifice of pipe chute to produce alga betterly.
However, the patent proposal still has the following defects: in the life cycle of aquatic plants, the root, stem and leaf of the aquatic plants can be subjected to necrosis and fall off, and the necrotic root, stem and leaf are easy to block an inclined tube at the bottom of the tank body after sinking into the bottom of the tank body, so that the water outlet of the inclined tube is influenced, and the function of the inclined tube sedimentation tank is lost; secondly, the aquatic plants have no planting fixed points, so the water-floating plant Chinese cabbage is selected, but the water-floating plants float irregularly and are easy to float to a water outlet along with water flow and even flow out along with the water flow, so the water outlet and the subsequent water treatment process are influenced; meanwhile, floating plants float indefinitely, and can easily expose the space above the inclined tube under the action of factors such as water flow, wind power and the like, and sunlight is directly irradiated to the inclined tube, so that algae are still easy to breed.
Therefore, how to design a scheme which can better utilize aquatic plants to avoid algae breeding at the pipe orifice of the inclined pipe and can better avoid the influence of the aquatic plants on the sedimentation and water outlet of the sedimentation tank becomes a problem to be further solved in the field.
