Description
Technical Field
The invention relates to the technical field of water environment protection, in particular to an ecological system for reducing pollutants in a water environment of a rice and shrimp field.
Background
China is a country with water resource shortage and frequent flood, the total water resource occupies the sixth place in the world, the average water occupation amount is only 2500 cubic meters, about 1/4 of the average water volume of the world, and the country is listed as one of 13 water-poor countries in the 110 th place of the world row. Water pollution is water pollution caused by the reduction or loss of the use value of water caused by harmful chemical substances. Acid, alkali, oxidant in sewage, compounds such as copper, cadmium, mercury, arsenic and the like, and organic poisons such as benzene, dichloroethane, ethylene glycol and the like can poison aquatic organisms, and influence drinking water sources and scenic spot landscapes. When organic matters in the sewage are decomposed by microorganisms, oxygen in the water is consumed, the life of aquatic organisms is influenced, after dissolved oxygen in the water is consumed, the organic matters are anaerobically decomposed, and bad gases such as hydrogen sulfide, mercaptan and the like are generated, so that the water quality is further deteriorated.
In order to reduce pollutants in water environment, various methods are adopted, and a repeated water use and circulating water system is adopted as much as possible, so that the waste water emission is minimized or the production waste water is recycled after being properly treated. Or putting water purifying agent into water environment, placing artificial wetland and the like, no matter which method is adopted, the water environment is treated, the comprehensive planning and reasonable layout are needed, the regional comprehensive treatment is carried out, the single treatment method often cannot achieve good treatment effect, and particularly, for the treatment of the water environment of the rice and shrimp fields, more methods are needed to coexist, because the water environment of the rice and shrimp fields causes water quality deterioration, the rice stems are rotten in the water, a large amount of dissolved oxygen in the water can be consumed, the shrimp fields are caused to lack oxygen, the rice stems can grow a large amount of toxic and harmful bacteria while rotting, and the damage to young shrimps with poor prevention capability is huge, so that the strengthening supervision is needed, and specific measures for protecting the water environment, controlling and managing water environment pollutants are formulated.
The most important thing of rice and shrimp symbiosis is to keep the health of water quality and free of pollution, so that the safe growth of crayfish can be ensured. Therefore, in the field where rice and shrimp are symbiotic, rice straw and too high stubble are not recommended to remain, and the straw and the stubble are easy to be decomposed and fermented when water exists in the rice field in summer, so that some toxic gas and toxic substances are generated, the water quality health in the rice field is affected, and the safe growth of the crayfish is further affected. Therefore, the cleaning of impurities on the surface of the water environment is also necessary.
Patent CN113354104a discloses an ecosystem suitable for deepwater environment remediation and a construction method thereof. The ecological system is used for matching an underwater illumination system, a photocatalytic bionic net and aquatic vegetation, the photocatalytic material on the photocatalytic bionic net is used for absorbing light energy of the underwater illumination system, continuously absorbing and degrading water pollutants, enriching microbial flora, decomposing organic pollutants of the water into nutritional ingredients for aquatic vegetation growth, and enabling the aquatic vegetation to start photosynthesis by underwater illumination so as to accelerate growth. The whole system depends on a visible light responsive photocatalytic material, starts natural recovery of the photo-synthetic water ecology, and starts natural force to purify the water body and restore ecology. In addition, the photocatalysis bionic net can absorb light energy and be used for decomposing water to generate oxygen, a large amount of newly-produced oxygen can attract fishes and shrimps, and promote the reproduction of ecological plants of surrounding water to achieve the dynamic balance of water ecology. However, the ecological system has single protection and treatment methods for water environment, and the use effect for water environment of various pollutants is not good only through one method of an illumination system.

after filtering for a period of time (for example, 4 h), stopping the driving motor 31 and the first water pump 711 to feed water, simultaneously feeding the water purifying agent into the water purifying agent feeding tank 53, then starting the driving motor 31 again, at this time, when the L-shaped rod 32 rotates, driving the roller group 6 to rotate, the rollers 65 roll in the annular chute 41, and meanwhile, the push blocks 63 slide against the inner wall of the annular chute 41, sequentially pass through the sliding blocks 57 of each sealing groove 5, when moving to the corresponding sliding block 57 position of the water purifying agent feeding tank 53, push the arc-shaped parts at the tail ends of the sliding blocks 57, enable the sliding blocks 57 to retract under the action of the springs 55, enable the first through holes 581 and the second through holes 571 to be butted, and enable the water purifying agent in the water purifying agent feeding tank 53 to fall into the water environment through the cover plate 58 by the first through holes 581 and the second through holes 571, and then the sliding blocks 57 pop up and seal the first through holes 581 and the second through holes under the action of the springs 55, and sequentially circulation to complete the water purifying flow;
if it is detected that the downstream water quality is poor, it may be that the interior of the water environment is polluted by artificial garbage, and it is required to clean the garbage and floating objects on the surface of the water environment, the push rod motor 331 is turned on to drive the inner sleeve rod 333 to extend along the outer sleeve rod 332, meanwhile, the guide rope 38 pulls the cleaning plate 34 to move along the guide groove 351 until the inner sleeve rod 333 moves to the outermost end of the outer sleeve rod 332, so that the baffle 37 of the cleaning plate 34 is located above the first baffle 35 and the second baffle 36, the state in fig. 4 is changed into the state in fig. 3, then the driving motor 31 is turned on to drive the L-shaped rod 32 to rotate, and simultaneously the whole cleaning assembly 3 is synchronously driven to rotate, net-shaped barbs arranged on the cleaning plate 34 collect the garbage and floating objects on the surface of the water environment, then the cleaning plate 34 is restored to the state in fig. 4, and then the cleaning plate 34 is replaced periodically by a worker;
if the diversity of shrimp or benthonic animal species in the water environment is monitored to be reduced, the microbial agent tank 51 and the shrimp larva culture tank 52 are used for culturing, the microbial agent and the shrimp larva to be put in are added into the microbial agent tank 51 and the shrimp larva culture tank 52, the driving motor 31 is started, at this time, the L-shaped rod 32 rotates to drive the roller group 6 to rotate, the roller 65 rolls in the annular chute 41, the push block 63 slides closely to the inner wall of the annular chute 41 and sequentially passes through the sliding blocks 57 of each sealing groove 5, when moving to the positions of the corresponding sliding blocks 57 of the microbial agent tank 51 and the shrimp larva culture tank 52, the arc-shaped parts of the sliding blocks 57 are pushed, the sliding blocks 57 are retracted under the action of the springs 55, the first through holes 581 and the second through holes 571 are abutted, the microbial agent and the shrimp larva to be put in are enabled to fall into the water environment through the cover plate 58, and the supplementation of the microbial agent and the shrimp larva is completed, and care is needed, the step cannot be performed synchronously with the above steps, and the entry of the microbial agent or the microbial agent into the filter bowl 71 or the shrimp larva is prevented from entering the interior of the cleaning plate 34.
