Description
Technical Field
The invention belongs to the technical field of water treatment, relates to a water treatment device, and particularly relates to an in-situ water quality improvement system of an air-lift type deep well coupling water pumping aerator.
Background
China has a large number of lake reservoirs, and with the improvement of the quality of human living environment, the number of landscape water bodies is increased. Many lakes, reservoirs and landscape water bodies have shallow water depth, slow water body flow updating and low turbulence intensity, and belong to typical shallow-layer slow-flow water bodies. Due to the low water flow speed of the water body, pollutants carried by inflow are easy to deposit at the bottom of a lake reservoir, and the level of nutritive salt of the sediments is gradually increased. Because the sediment nitrogen and phosphorus nutritive salt level is higher than that of the water body, under the action of bottom water body anaerobism and sediment resuspension caused by wind wave generation and ship wave generation, a large amount of nutritive salt in the sediment can be released into the water body, thereby causing water eutrophication and providing sufficient material conditions for algae outbreak. In addition, the fact that the whole water body is strongly illuminated due to the shallow water depth is another important factor for algae outbreak in shallow stagnant water, and the situation that light limitation does not exist in algae growth.
The algal outbreak is the most visual representation of water eutrophication, and has serious influence on water quality and water functions. The ecological balance of the water body in the algae outbreak period is damaged to cause a large amount of aquatic animals to die, and rotten and decomposed animal and plant residues become a part of sediments, so that the pollution level of the sediments is increased; high algae content water can affect the normal operation of a water plant after entering the water plant, and a series of problems of increased coagulation dosage, filter tank blockage, shortened backwashing period, increased backwashing water consumption, increased factory water disinfection byproducts and the like are caused; in addition, part of the algae can release odor substances, so that the sensory properties of the water body are rapidly deteriorated.
Under the condition that the exogenous pollution is basically controlled, the technical method for controlling the eutrophication of the water body at home and abroad mainly comprises the endogenous pollution control and the direct algae control. The endogenous pollution control comprises water diversion and sewage flushing, sediment dredging, sediment passivation and bioremediation, and a large amount of high-quality water sources are needed for the water diversion and sewage flushing and the sediment dredging, so that the cost is high; the bottom sludge passivation has the risk of re-release because the pollutants still exist in the sediment; the problems of activity maintenance and environmental adaptability of bioremediation in practical applications remain to be solved. The direct algae-controlling technology includes physical algae-removing method represented by ultrasonic algae-removing and shading algae-removing, chemical algae-removing method represented by adding algicide to kill and crack algae cells, and biological method represented by putting fishes and planting aquatic plants. These methods of algae removal have not been applied in large scale in practical production due to their high cost, potential ecological safety hazards or limited effectiveness. Meanwhile, the current technology only aims at algae control or endogenous pollution control, and the treatment of both symptoms and root causes of water eutrophication is not realized.
The prior art discloses shallow slow-layer water gas-lifting deep-well pressure-increasing algae-controlling and pollution-removing equipment, and discloses a bubble cutting biological contact oxidation enhanced water-lifting aeration water quality improving device. A shallow slow-flow water gas-lifting deep-well pressure-increasing algae-floating device utilizes the pressure action of a deep well to break a blue-green algae air bag and lose the floating capacity, and the water outlet of the device is refluxed to a water body, so that the turbulent fluctuation strength of the water body is enhanced, the algae outbreak can be effectively controlled, and the device does not have the action of reducing endogenous pollution. A water quality improving device for enhancing water raising aeration through bubble cutting and biological contact oxidation can contact oxygen-enriched water with a biological contact oxidation device while mixing and oxygenating, can effectively reduce the content of nitrogen and phosphorus nutritive salt and organic pollutants with concentration in a water body, and fundamentally solves the problem of water eutrophication. Because the shallow layer stagnates the slow flow water body and the water depth is shallow, the water body mixing algae removal effect produced by the bubble cutting biological contact oxidation enhanced water-lifting aeration water quality improving device is limited.
