Maintenance repair apparatus for closed water bodies

Abstract

The invention discloses a maintenance repair apparatus for closed water bodies, which is can be used in closed water bodies required to be rebuilt or repaired such as landscape water and lake. The apparatus provided by the invention is divided into a nitratlon reaction zone, a micro electric field processing zone and a biology phosphorus removal zone. The nitratlon reaction zone mainly uses a slope surface of a water body bulkhead, the vertical cobblestones with orderly arrangement are provided on the slope surface, a soft material is placed in an included angle formed by cobblestones and the slope surface for fixing nitrobacteria to realize the nitrification. The water flowed downwardly from the slope surface enters into the micro electric field processing zone, a cathode and an anode are provided in the zone, and a certain proportion of particle electrode and insulation particles is filled in the whole zone. The biology phosphorus removal zone uses a high efficiency adsorption material to form a phosphor absorption layer, and an ecological plant is planted on the phosphor adsorption layer. The power supply source of the maintenance repair apparatus depends on solar energy, thereby non energy consumption is realized; the slope surface water bodies and atmosphere are fully contacted, and an aeration system is saved. The maintenance repair apparatus and the nature landscapes are formed into one whole body, and the eutrophication problem of the water bodies can be solved, and the natural environment enables beautification.

Description

technical field [0001] The invention relates to a device for repairing eutrophic closed water bodies or maintaining clean closed water bodies by combining biological, chemical and physical methods, especially a repair device that can maintain natural beauty without energy consumption. Background technique [0002] With the improvement of living standards, people have stricter requirements on the living environment, but many lakes, man-made lakes, community landscapes and other water bodies have various degrees of eutrophication, black odor and other problems. On the one hand, because people use a lot of detergents, cleaning agents, etc., a large amount of elements such as nitrogen and phosphorus are discharged into the water body; The water quality is in an anoxic state, and organic matter accumulates anaerobically at the bottom of the water, which increases the degree of eutrophication and seriously affects the beauty of the natural environment and the living environment of...

Problems solved by technology

The invention patent with the patent publication number CN1355144A discloses a comprehensive method of using wind energy and biological floating bed to treat sewage. It installs biological filter materials and amphibian plants for nitrogen and phosphorus removal on the floating bed unit to absorb and remove nitrogen and phosphorus. Considering the problem of electricity, wind energy is used to aerate water bodies and generate electricity under underwater light, but plants have a limited ability to absorb nitrogen and phosphorus. According to data, currently the most harmful water hyacinth has the strongest nitrogen and phosphorus absorption ability. It is only 0.24% of the wet weight, and the phosphorus content is only 0.022% of the wet weight. At the same time, the use of wind energy as the power source also has considerable instability. In areas where the airflow is relatively stable, the application of the invention and its treatment The effect will be greatly affected
