Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the method for treating a lightly polluted river disclosed by the invention comprises a sewage treatment device 2 arranged at the upper ends of bank protection walls 1 at two sides of the river along the river, wherein the sewage treatment device 2 keeps a certain distance from the surface of the river. The processor 2 comprises a shell 3, and a condensation plate 4 and a water storage plate 5 which are arranged in the shell 3 at intervals up and down. And a water inlet filter chamber 6 is arranged on the condensation plate 4, an evaporation chamber 7 is arranged between the condensation plate 4 and the water storage plate 5, and a cooling chamber 8 is arranged below the water storage plate 5.
As shown in fig. 1 and 2, the housing 3 is fixed to the upper end of the revetment wall 1 by a mounting bracket 9, and a certain gap is maintained between the housing 3 and the revetment wall 1. A water suction pump 10 is arranged between the shell 3 and the revetment wall 1, the water suction pump 10 is connected with a water inlet pipe 11, one end of the water inlet pipe 11 extends into river water, and the other end of the water inlet pipe is communicated with the water inlet filter cavity 6. The water inlet filter cavity 6 is also internally provided with a membrane wire filter element 12, and the membrane wire filter element 12 comprises a filter frame 13 and a membrane wire filter screen 14 arranged in the filter frame 13. The two opposite sides of the upper end in the water inlet filter chamber 6 are fixed with barrier strips 15, and the filter frame 13 of the membrane wire filter 12 is placed on the barrier strips 15. After the membrane-wire filter element 12 is installed in the inlet filter chamber 6, the height thereof is lower than the position where the inlet filter chamber 6 is connected with the inlet pipe 11. Therefore, when the water pump 10 pumps the river water into the inlet filter chamber 6, the river water is filtered by the membrane wire filter 14 in the process of flowing down. The upper end of the housing 3 is also rotatably connected with a protective cover 17, and when the membrane wire filter 14 is used for a long time, the membrane wire filter 12 can be replaced by opening the protective cover 17.
The condensation plate 4 comprises two side connection portions 18 and a groove portion 19 located in the middle, the connection portions 18 are fixedly connected with two sides of the shell 3, and the upper surface of the groove portion 19 is recessed while the lower surface thereof protrudes. The connecting portion 18 is further provided with a drainage hole 28, when the river water is pumped into the water inlet filter chamber 6, the groove portion 19 is filled with the river water, and the river water flows down from the drainage hole 28 after the groove portion 19 is filled with the river water and enters the evaporation chamber 7.
As shown in fig. 2, two raised plates 21 are disposed at an interval in the middle of the water storage plate 5 in the evaporation chamber 7, a receiving groove 22 is fixed on the upper end of the raised plates 21, and the receiving groove 22 is located right below the groove 19. The river water flows into the evaporation cavity 7 and then is positioned on the water storage plate 5, and the two sides of the two heightening plates 21 are communicated through the communicating pipe 23. The bearing groove 22 is an arc-shaped plate with two closed ends, the lower end surface of the bearing groove 22 is connected with a conduit 20, and the conduit 20 is positioned between the two heightening plates 21. An electric heater 24 is further arranged on the water storage plate 5, the electric heater 24 is a resistance wire, and the electric heater 24 is connected with a power supply. When the power supply starts to supply power to the electric heater 24, the water in the evaporation chamber 7 is heated and a large amount of evaporation rises and adheres to the lower surface of the condensation plate 4 to form distilled water. Since the lower surface of the groove portion 19 is downwardly convex, water droplets condensed on the condensation plate 4 are collected on the lower surface of the groove portion 19 and dropped into the receiving groove 22. Because the upper surface of the groove part 19 is filled with river water, the groove part 19 is not easy to be heated and heated, and is more easy to be condensed into water drops when the water vapor rises. The evaporation cavity 7 is also connected with a water outlet pipe 25, and the water outlet pipe 25 is connected with a water outlet pump 26. When the river water in the evaporation cavity 7 is evaporated to a lower position, the concentration of various pollutants in the river water is also higher, and the river water in the evaporation cavity 7 is discharged and collected by the water outlet pump 26 for further treatment. Then, the water pump 10 is used for inputting the river water to be treated into the processor 2, so that the river water in the groove part 19 can be replaced and kept at a lower temperature position, and when the river water entering the evaporation cavity 7 is heated again to evaporate and meets the groove part 19, the river water can be quickly condensed into water drops because the groove part 19 keeps the lower temperature.
Because the conduit 20 is located between the two raised plates 21, the distilled water entering the conduit 20 is less susceptible to the high temperature river water in the evaporation chamber 7. The distilled clean water can finally enter river water at a lower temperature, so that the ecological environment of the river water cannot be damaged due to the fact that the river water is discharged into high-temperature water, and the concentration of pollutants in the river water is diluted and reduced.
As shown in fig. 1 and 2, cooling plates 27 made of metal are alternately arranged on two opposite sides in the cooling cavity 8, and the cooling plates 27 are obliquely arranged downwards, wherein the lower end of the cooling plate 27 with a higher height is positioned above the higher end of the cooling plate 27 with a lower height. Therefore, when water flows down from the guide duct 20 onto the cooling plates 27, it can be in contact with the respective cooling plates 27 in sequence, and the cooling plates 27 absorb heat of the distilled water, so that the distilled water is further cooled. Cooling holes 16 are further formed in two side walls of the cooling cavity 8, and when air flows around the processor 2 due to the arrangement of the cooling holes 16, hot air in the cooling cavity 8 can be driven faster, so that the cooling cavity 8 can be kept at a lower temperature. The distilled water cooled by the cooling chamber 8 is finally introduced into the river below the processor 2.
The specific working conditions are as follows:
after setting up treater 2 in the upper end of revetment wall 1, the one end of inlet tube 11 stretches into in the river, through starting suction pump 10 with the river suction intake to intaking in filtering chamber 6, the river enters into evaporation chamber 7 after the filtration of membrane silk filter piece 12, then make the river be heated and evaporate through supplying power for electric heater 24, can condense into the drop of water and then drip to accepting groove 22 after the lower terminal surface that vapor contacted condensing plate 4, and then flow into further cooling in cooling chamber 8 through pipe 20, flow into the concentration of the inorganic pollutant and the organic pollutant of dilution river water in the river with clean distilled water at last.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
