Description

Floating water inlet folded plate rotating ecological dam

Technical Field

The utility model belongs to ecological engineering, environmental engineering, agricultural non-point source pollution control engineering field are one kind and are found in paddy field drainage canal system for holding back the paddy field and moving back water, get rid of nutritive salts such as nitrogen phosphorus that moves back water, prevent that it from discharging into natural water, alleviate surface water non-point source pollution load, restore canal system ecosystem, improve the farmland and move back water and receive the ecological dam of flap gyration of intaking that floats of water quality of water.

Background

In China, the contribution rate of nitrogen and phosphorus to agricultural non-point source pollution load is high. The contribution rates of nitrogen and phosphorus to agricultural non-point source pollution loads reach 57% and 67% respectively, but the utilization rate of nitrogen and phosphorus fertilizers in agricultural production is generally low and is respectively between 10% -40.5% and 7.3% -20.1%, and a large amount of nitrogen and phosphorus are lost from farmlands and enter a receiving water body. According to research, more than 50% of nitrogen pollution load and more than 30% of phosphorus pollution load in surface water body of China come from agricultural non-point source pollution. The surface water body is seriously polluted by agricultural non-point sources.

The drainage canal system of the rice field is a link connecting the rice field and the downstream surface water body, and can intercept and convert nitrogen and phosphorus pollutants through physical, chemical and biological effects of soil adsorption, plant absorption, microbial metabolism and the like. However, the aim of effectively reducing the nitrogen and phosphorus pollution load is difficult to achieve by only relying on the canal system as a passive treatment means, and particularly in the concentrated water-withdrawal period of the rice field, the nitrogen and phosphorus in the canal system water body are difficult to be effectively degraded due to the short hydraulic retention time, the water quality is difficult to meet the water inlet quality requirement of the receiving water body, and the water environment quality of the receiving water body is seriously influenced.

The ecological dam technology utilizes the ecological principle and depends on plant absorption and microbial degradation to achieve the purpose of reducing nitrogen and phosphorus pollution. At present, according to the reports of relevant documents, the ecological dam is mainly applied to the breeding industry of economic fishes, and the ecological dam has the main function of reducing and relieving the pollution of polluted water containing residual feed, rotten aquatic plants, fish excrement and the like to open water areas around a breeding farm. The ecological dam is mainly composed of an overwater plant floating bed and an underwater filler floating bed, and can be well suitable for fishery culture water areas with large water depth and less suspended matters.

However, due to the structural composition, the ecological dam has the defects that the ecological dam has not been overcome yet, such as good phosphorus removal capability, lack of effective suspended matter and turbidity removal capability, low hydraulic retardation capability and the like.

The current ecological dam technology has less consideration on the function of the matrix in structure and treatment effect. The substrate is a material foundation attached to the growth of the root system of the plant, the good substrate is beneficial to the normal growth of the plant, the substrate also provides a microenvironment for the growth of microorganisms, and meanwhile, the substrate which has high physical strength, stable chemical property, porosity and large specific surface area plays an important role in removing pollutants, particularly phosphorus.

The drainage channel system of the rice field has completely different physical structural characteristics from those of fishery farms. Regardless of the branch drainage channel and the main drainage channel, compared with the cultivation water area, the drainage channel of the rice field generally has shallow water depth, so that the hydraulic condition changes remarkably, and particularly, the impact load on the aspects of water power and water quality can be formed on the drainage channel of the rice field in the drainage period. Obviously, the current ecological dam technology applied to the fishery culture system is difficult to adapt to the drainage channel system of the rice field. Therefore, the ecological dam technology applied to the drainage canal system of the paddy field needs to be well adapted to the structural characteristics, hydraulic conditions and water quality characteristics of the canal system.

Particularly, the ecological dam applied to the paddy field canal system has a larger optimized design on the structure. On one hand, the water blocking capacity is enhanced, the water flow path length is increased, and the hydraulic conditions in the ecological dam are optimized; on the other hand, the design of the water intake is to avoid the load impact of the water quality and the water quantity change of the inlet water on the ecological dam treatment system as much as possible to adapt to the variable hydraulic conditions; secondly, the treatment capacity is good in denitrification and dephosphorization effects, and the treatment capacity is strong for suspended matters; then, the removal efficiency of the ecological dam is enhanced through reasonable configuration and breeding of plants; the most important point is that the key role of the matrix in the ecological dam needs to be considered in a key way, good effects of removing suspended matters, removing nitrogen and phosphorus are achieved through reasonable matching of matrixes of different types and sizes, and meanwhile, the matrix with saturated adsorption capacity can be replaced conveniently structurally.
