Description

Treatment system applying river black and odorous water body endogenous restoration

Technical Field

The utility model relates to an use endogenous prosthetic processing system of black smelly water in river.

Background

The main reasons for the formation of urban black and odorous water bodies are that urban inland rivers are generally small in scale, the water system communication capacity is poor, the hydrodynamic condition is poor, the water change rate is low, and the phenomenon of local black and odorous water bodies is caused. When the flow velocity of the urban inland river water is slow, a large amount of silt carried in the river water can form a silt layer at the bottom of the water along with the lapse of time, and bottom mud contains pollutants and putrefaction formed by uncleaned aquatic plants, algae and the like. In addition, the sewage collecting pipes are not completely arranged in the partially built-up area and the most non-built-up area, the phenomenon of mixed rain and sewage is serious, and the sewage is directly discharged into the surrounding water area to cause the formation of black and odorous water. Domestic sewage and enterprise wastewater are directly discharged into a water body without treatment or discharged into the water body without reaching the standard after treatment.

The smaller the scale of the urban river channel is, the faster the accumulation and increase speed of the sludge layer is correspondingly increased; the phenomenon causes that aerobic decomposition is only carried out on the surface of sludge, the inside of the sludge is mainly in an anaerobic state, and under the anoxic condition, the decomposition process of organic matters is very slow, the thickness of the sludge is continuously increased, and the color gradually becomes dark and black. Meanwhile, the mixed grafting of rain and sewage causes the sewage to enter the river, and the progress of water body blackness and odor is aggravated by the pollutants on the ground surface entering the river along with the rainwater. The traditional method mainly adopts a physical dredging method and a chemical agent method to achieve the purpose of purifying water resources. However, the physical dredging method has high cost investment and limited maintenance period, and although the chemical method is widely applied in the treatment process of the black and odorous water body, the chemical reagent used by the method may cause certain pollution to water resources. The disadvantages of the method are that the work load of dredging is too large and the cost is high; the physical method treats the symptoms and does not treat the root causes; the black and stink phenomena are repeated; the treatment effect maintaining period is short.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an use endogenous prosthetic processing system of black smelly water in river. The problems that the cost investment of a physical dredging method is too high and the maintenance period is limited are solved; the chemical method has large dredging workload and high cost; the physical method treats the symptoms and does not treat the root causes; the black and stink phenomena are repeated; short treatment effect maintaining period.

The utility model relates to a treatment system for endogenous restoration of a black and odorous water body of a river, which comprises a solar aeration component and an endogenous ecological device; the solar aeration components are arranged in the endogenous ecological device at intervals; the endogenous ecological device comprises a PVC biological filler layer and a honeycomb stone filter layer; the honeycomb stone filtering layer is arranged at the bottom of the endogenous ecological device, and the PVC biological filler layer is arranged on the upper layer of the honeycomb stone filtering layer.

The utility model has the advantages that:

the utility model discloses an endogenous synthesis is administered, improves ecosystem, follows the fundamental solution quality of water pollution and administers, reaches the effect of treating the primary and secondary symptoms. The method can rapidly eliminate the black and odorous pollutant in the river, the removal rate of COD index is 80-90%, the removal rate of total phosphorus is 90-95%, and then ammonia nitrogen and total nitrogen substances in water are removed through advanced treatment of microorganisms, and the removal rate of ammonia nitrogen reaches 80-95%. The process has high removal rate to various pollutants in a flow field by combining physicochemical and biochemical processes, is particularly suitable for treating symptoms and root causes of the black and odorous water with large water volume, and solves the repeated phenomenon of black and odorous water.

The utility model discloses but the filler layer load microorganism activated factor activation native microorganism fast growth adjusts endogenous ecosystem, forms virtuous circle, finally reaches to utilize self ecological regulation water purification quality.

The utility model discloses influencing the condition that the bed mud increases at the effective control external source, making endogenous effect reach the decrement effect, forming good circulation, the bed mud constantly reduces, and then improves quality of water.
