Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of natural water treatment, and particularly relates to a mobile soil infiltration floating bed for purifying reservoir pond water quality and a using method thereof. Background Art
[0002] There are many lakes and reservoirs in China. According to relevant data statistics, there are about more than 80,000 reservoirs in China, with a reservoir capacity of 4.3×10^11 m³. While reservoirs have great potential in aspects such as water supply, flood control, shipping, fishery and power generation, they also play a very important role in maintaining the ecosystem. With the rapid economic development and the further promotion of urbanization, industrialization and agricultural modernization, the emissions of domestic sewage and industrial and agricultural wastewater gradually increase, resulting in the deterioration of water quality resources, affecting the water quality of reservoirs, posing a serious threat to the reservoir water ecosystem, and also affecting people's normal life. Therefore, the urgent task is to carry out reservoir ecological restoration and improve the water quality of reservoirs.
[0003] Currently, the main methods used to improve the water quality of reservoirs, lakes, rivers, etc. are to set up water purification devices at fixed positions to introduce surrounding sewage or to supply oxygen to the water by generating vortices. However, the method of purifying sewage using such fixed water purification devices requires a large number of water purification devices or large-capacity water purification devices to be set up, and their setting and operation costs are high. At the same time, the fixed devices cannot accurately and flexibly treat the sewage in the areas where the water quality does not meet the standards, reducing the efficiency of reservoir pond sewage purification. To solve the problems of such fixed water purification devices, the current solution is to try to use mobile water purification devices to specifically treat the polluted areas of reservoir ponds. However, the existing mobile water purification devices require staff to drive or operate manually, and the operation and operation costs are relatively large.
[0004] The soil infiltration device is a type of land treatment. By controlling the discharge of turbid sewage on the surface of the infiltration medium, it undergoes physical, chemical and biological effects during the infiltration process, and finally achieves the purpose of purifying turbid sewage. This device can use fillers with better permeability as filter media instead of natural soil, and use corresponding fillers for different pollutants to be removed in turbid sewage. Under the synergistic effect of filtration interception, adsorption and biodegradation, it can efficiently remove pollutants, and has the advantages of low construction cost and operation cost, convenient management, strong adaptability to load changes, certain biological safety of the effluent, and significant ecological and environmental benefits.
[0005] Therefore, to solve the above problems, this paper proposes a mobile soil infiltration floating bed for purifying reservoir pond water quality and a using method thereof. Summary of the Invention

[0010] The fine filtration tank includes three adjacent packing boxes. The first packing box is connected to the lower end of the second packing box, and the second packing box is connected to the upper end of the third packing box; in the first packing box, a mixed packing of volcanic stone and fly ash and cobblestones is laid sequentially from top to bottom, in the second packing box, a red mud molecular sieve packing and cobblestones are laid sequentially from top to bottom, and activated carbon packing is laid in the third packing box;
[0011] The filling amounts in the first packing box, the second packing box and the third packing box are 40% - 60%.
[0012] Further, an air storage tank is installed at the lower end of the bottom of the aeration tank, and the air storage tank is connected to a gas distribution plate at the inner bottom of the aeration tank; a sterilization lamp and a chemical agent tank are installed at the upper end of the aeration tank.
[0013] Further, a foam filtration and collection device is installed in the foam filtration tank. The water outlet of the foam filtration tank is connected to the monitoring tank. A water quality detector is installed in the monitoring tank. A water pump is installed at the bottom of the monitoring tank.

[0059] Example 3
[0060] Water purification working principle: Under the action of gravity, the influent first passes through the mixed packing area of volcanic stone and fly ash to reach the cobblestone layer at the bottom of the three-stage vertical flow soil infiltration device. The sewage is preliminarily purified under the adsorption, filtration and acid-base adjustment of volcanic stone and fly ash. After water distribution through the cobblestone layer, the sewage enters the red mud molecular sieve packing area, where heavy metal ions in the sewage are effectively removed and decolorized. After further purification, the sewage enters the activated carbon packing area for deep purification. The outlet pipe collects the purified turbid sewage together and leads it into the surface turbulent sieve filtration device;
[0061] The aeration in the aeration tank is continuous aeration. The inlet gas of the aeration pipe is O3. There is a gas distribution plate 12 on the aeration pipe, which is used to cut the air into bubbles. When the sewage enters the aeration tank, the aeration pipe starts to aerate, the air pressure increases, and the gas is cut into small bubbles by the porous plate and floats upward. When the intelligent flotation reagent dosing device senses the aeration, it starts to add the flotation reagent for aeration flotation. At the same time, the ultraviolet sterilization lamp 13 is turned on for further sterilization. When the pollutants float to the water surface with the bubbles, they enter the foam filter tank 15 with the water flow, and the bubbles entraining the pollutants are intercepted, waiting for manual regular cleaning of the reflux tank. Ozone generates hydroxyl radicals under the irradiation of ultraviolet light, accelerating the degradation of organic matter. Through the strong oxidation of hydroxyl radicals, while removing organic matter and reducing COD, the transparency and chromaticity of turbid sewage are improved, further helping to purify the sewage.
