Description
Technical Field
The invention belongs to the technical field of water quality purification systems, and particularly relates to a self-running slow-flow water body filter feeding water quality strengthening purification system.
Background
River channels in plain river network areas of China mostly adopt slow-flow water bodies, the self-purification capacity of water quality is poor due to poor hydrodynamic conditions, pollution load accumulation is increased along with continuous input of watershed non-point source pollution, and the self-purification of the water quality of the river channels is difficult to maintain. In order to prevent the deterioration of the water quality of the slow-flow water body and further improve the water quality, various auxiliary purification facilities are applied to the treatment of the slow-flow water body. The main facilities comprise in-situ treatment facilities and ex-situ treatment facilities, wherein the in-situ treatment facilities comprise the steps of adding a microbial agent into a river channel, arranging a plant floating bed, putting artificial aquatic plants, placing artificial fillers, additionally arranging a water meter or underwater aeration and the like; and river course quality of water dystopy is purified more and is adopted river course water bypass to purify, sets up quality of water purifier and provides the electric energy and the medicament of operation at the river bank. Unpowered measures in the in-situ or ex-situ purification method have poor effects, and the powered methods are difficult to operate for a long time due to the difficulty in overcoming high-energy-consumption and low-efficiency processes such as river water lifting or aeration. For example, aeration on the surface of a river water body has poor aeration effect on the bottom of the water body and large disturbance on the water body, so that the turbidity of the slow-flow water body of the plain river network is large. If the aeration is directly carried out at the deep part of the river channel, the water head pressure of the overlying water body needs to be overcome, the energy consumption is high, the bubbles directly rise, the contact time with the water body is short, the reoxygenation effect is poor, and the energy efficiency is low. In the process of lifting river water to a bypass water treatment facility for treatment, a large amount of river water is lifted, so that the energy consumption is high, and the sewage treatment facility needs to additionally occupy land resources. And thirdly, even if the river water body belongs to poor v-class water quality, the concentration of pollutants is still much lower than that of inlet water of a sewage treatment plant, and the river water with low pollutant concentration is treated by adopting a river water bypass purification facility similar to the sewage treatment plant, so that the efficiency is extremely low, the long-term operation cost is high, and the continuous operation is difficult.
The water quality of the slow-flow water body needs to be enhanced and purified to improve the water quality purification capacity, so that the defect of the self-purification capacity of the water quality is overcome, the key point is to improve the reoxygenation condition of the water body, and the traditional in-situ aeration and bypass aerobic treatment purification need to consume a large amount of power and energy. The high-power extra power consumption enables the water quality of the river to be reinforced and purified by relying on external power, and independent and sustainable long-term operation is difficult to achieve. The water surface of the slow-flow water body has wind energy and light energy, and wind-light complementation can be basically realized. If the in-situ wind and light energy of the slow flow water body can be relied on, the self-supply and independent operation of the energy for strengthening and purifying the water quality of the slow flow water body such as the river channel can be realized, and the long-term sustainable water quality strengthening and purifying of the river channel can be realized.
As new materials are continuously researched and developed, the aeration membrane applied to the aerobic treatment of domestic sewage at present has made a breakthrough, and the flaky bubble-free membrane can realize the reoxygenation of the water body on the premise that no bubbles are generated in the water body in the aeration process and the air is not in direct contact with the water, carry out the aerobic treatment on the sewage and remove reducing substances such as chemical oxygen demand, ammonia nitrogen and the like. The outer surface of the flaky bubble-free film can form a microbial film, and the microbial film directly utilizes oxygen diffused in the film to purify water. Because the air is not contacted with water in the aeration process, the air does not need to overcome an overlying water head to do work, and the requirement on air pressure is low, the bubble-free membrane aerobic treatment of the sewage has remarkable energy-saving advantage. At present, the device and the method for applying the flaky bubble-free aeration membrane to water quality enhancement and purification of the slow flow water body such as a river channel and the like are reported, and the bubble-free in-situ water quality enhancement and purification facility which is applied to the slow flow water body and can realize self-sufficiency of energy is less available. The urgent need is to provide a self-running slow-flow water body filter feeding water quality strengthening and purifying system to solve the above background technology deficiencies.

in the invention, the solar power generation panel 11 can obtain solar energy for power generation, the wind power generator 12 can obtain wind energy for power generation, the two power generation modes can supply energy complementarily in sunny and no-wind weather and overcast and rainy wind weather, the system can be supplemented with energy all the day, the system can automatically run under the condition of no external power input, the generated electric energy is stored by the electric storage device 13, and the electric storage device 13 simultaneously provides power supply for the air pump 14, the timing control electromagnetic valve 15 and the electric propulsion impeller 211.
The loading platform 1 is lifted above the water surface by a buoy 16 fixed at the lower part, and a hanging bracket 17 fixed at the lower part of the loading platform 1 extends into the water and is connected with the filter feeding strengthening purification cylinder 2. The upper end of the filter-feeding reinforced purifying cylinder 2 is 30-50cm away from the water surface. Under the condition of power supply of the electric storage device 13, the electric propulsion impeller 211 starts to work and propel flow, and water on the upper part close to the water surface passes through the water inlet grating 21 after being reoxidized by the atmosphere and is propelled to the deep part of the filter feeding reinforced purification cylinder 2 by the electric propulsion impeller 211. Meanwhile, the air pump 14 pumps air into the bubbleless hollow oxygenation membrane 23 through the air inlet pipe 141 and the air inlet port 231 connected thereto under the condition that the electric storage 13 is supplied with electricity. The air meets the relatively low-temperature membrane wall at the deep part of the non-bubble hollow oxygen-filled membrane 23 to form condensed water, the condensed water is accumulated at the lower part of the non-bubble hollow oxygen-filled membrane 23, and oxygen in the air is diffused to the external water body through the membrane wall to reoxygenate the water outside the membrane. The air after oxygen consumption is discharged from the air outlet port 233 and the air outlet pipe 234 at the other end of the bubbleless hollow aeration membrane 23 and the timing control solenoid valve 15. Under the condition of oxygenation, a large number of microorganisms can be attached to the surface of the foamless hollow oxygenation membrane 23, which is in contact with water, and the spherical frame filler 235 filled in the gaps of the foamless hollow oxygenation membrane 23 and grow, so that the reductive pollution of organic matters, ammonia nitrogen and the like in water can be intensively purified.

The condensed water in the non-bubble hollow oxygen-filled membrane 23 is continuously accumulated along with the working time, at the moment, the timing control electromagnetic valve 15 can close the valve for 1-5min every 1-5h, so that the internal air pressure of the non-bubble hollow oxygen-filled membrane 23 is increased, the one-way drain valve 232 at the lower end of the non-bubble hollow oxygen-filled membrane 2 is pushed open, the accumulated condensed water is emptied, and the effective circulation and oxygen transfer of the air in the membrane are ensured. The timing control solenoid valve 15 is turned on again after the set time, the air outlet pipe 234 can normally discharge air under the low air pressure condition, and the air pump can continue to work under the pressure in the low power consumption state.

The filter feeding strengthening purification cylinder 2 is connected with the lower end of the hanging frame 17 and is vertically arranged to be completely immersed in the water body, so that the rolled foamless hollow oxygen-filled membrane 23 is also in a vertical state, and sludge deposition on the surface of the membrane can be avoided. The filter feeding strengthening purification cylinder 2 feeds water from top to bottom, and enough water which is close to the water surface and is subjected to atmospheric reoxygenation enters, so that the reoxygenation load of the membrane can be saved, the air inflow for reoxygenation is reduced, and the energy conservation is realized. The electric propulsion impeller 211 arranged on the water inlet grille 21 vertically propels water flow downwards, the flow velocity of the flow pushing cross section is between 0.02 and 0.2m/s, and the blockage and excessive washing in the filter-feeding reinforced purifying cylinder 2 can be effectively controlled. The aperture of the water inlet grid 21 at the upper end of the filter-feeding reinforced purifying cylinder 2 is smaller than 1cm, so that large particles in water can be effectively prevented from entering the filter-feeding reinforced purifying cylinder 2 to block water filtering gaps and scratch the surface of the membrane. The filter feeding strengthening purification cylinder 2 is internally provided with a bubble-free hollow oxygen charging membrane 23, air flows through the hollow membrane, and is diffused into a water body through the membrane, bubbles are not directly generated in the water in the aeration process, only gas passes through the membrane without overcoming water pressure aeration, the required air inlet pressure is small, and the reduction of oxygen charging energy consumption is realized.
