Description
Technical Field
The invention relates to an in-situ ecological restoration structure for surface water and underground water. Is suitable for the technical field of surface water and groundwater treatment.
Background
The silt deposition on the downstream of the yellow river leads the surface of the river dike inner bar to be generally higher than the ground surface of two banks by 4-6 m, and the height difference of partial river segments is even more than 10m, so that an overground suspended river is formed, and a unique water circulation system is also formed, namely, the yellow river water is supplied with shallow groundwater in one way all year round, so that the groundwater level is increased. Therefore, when the groundwater level is higher than the surrounding surface water level, groundwater seeps from the high water level to the low water level, and surface water is supplied; when the peripheral surface water level is higher than the shallow groundwater level, the surface water is used for measuring and infiltrating and supplementing the groundwater.
The water quality pollution of the surface water is serious due to the influence of agricultural irrigation, livestock and poultry cultivation, sewage discharge and industrial production on the downstream yellow sheet area of the yellow river. Meanwhile, the shortage of water resources promotes people to continuously exploit and utilize groundwater, and the problems of original geological environment and groundwater environment pollution are also severe. According to investigation data, the regional surface water and groundwater have the problem of exceeding the standard throughout the year, and pollutants in the surface water and groundwater are exchanged along with the regional surface water and groundwater in the process of mutual supply, so that the water pollution condition is aggravated.
At present, studies on in situ purification of surface and ground water have been quite extensive, but less on achieving contaminant removal during the mutual replenishment of surface and ground water, especially under specific water quality conditions downstream of the yellow river along the yellow patch.

Detailed Description
The embodiment is an in-situ ecological restoration structure for surface water and underground water, which is paved at the bottom of a river or lake (such as a river channel, a lake, a pit pool and the like around a yellow river suspended river section) with the water level higher than the underground water level in a high-water period and the water level lower than the underground water level in a low-water period.
The in-situ ecological restoration structure in this example is composed of a bottom filter layer, a filler layer, a top filter layer and a planting layer from bottom to top, wherein the bottom filter layer is composed of a filter screen and a porous ceramic filter plate from bottom to top; the filler layer is composed of an active alumina layer, a biochar layer, and a zeolite and lime layer from bottom to top in sequence; the top filter layer is sequentially provided with a porous ceramic filter plate and a filter screen from bottom to top; submerged plants are planted on the planting layer.
The filter screen in the embodiment is formed by processing a stainless steel wire mesh, and the aperture is 30-50 mm so as to prevent soil from blocking the filter holes and filter large-particle pollutants; the porous ceramic filter plate has a pore density of 7-13 pores/25.4 mm.
In the embodiment, the thickness of the active alumina layer is 15-20 cm, the particle size of the active alumina is 5-15 mm, and the active alumina has a good adsorption effect on fluorine in a water body.
In the embodiment, the thickness of the biochar layer is 20-30 cm, the particle size of the biochar is 15-30 mm, and the biochar can not only utilize the larger porosity and specific surface area of the biochar to adsorb pollutants, but also remarkably promote the growth of plants, improve the capturing capability of the biochar on nutrient substances required by the plants such as organic matters, nitrogen, phosphorus and the like, and indirectly strengthen the removing capability of the pollutants.
In the embodiment, the thickness of the zeolite and the limestone layer is 15-20 cm, the particle size of the zeolite and the limestone is 30-50 mm, and the ratio of the zeolite to the limestone layer is 1:1, nitrogen and phosphorus in the water body can be effectively removed.
The thickness of the planting soil laid in this example is 350-500 mm. The submerged plant is prepared from black algae,
One or more plants with good effect of removing nitrogen and arsenic in water body, such as herba Sonchi Oleracei, goldfish algae and Sargassum foxtail. The submerged plants can directly absorb nutrient substances from water body through stems and leaves, and can absorb pollutants through developed root systems and microorganisms attached to the root systems, so that the pollutant removal rate is improved. In addition, their aeration structure is particularly developed, facilitating gas exchange in the absence of air in the water.
The working principle of this embodiment is as follows:
A. When the surface water level in the river and the lake is higher than the shallow groundwater level, the surface water seepage measurement firstly passes through submerged plants, and under the action of the submerged plants with good absorption effect on nitrogen and arsenic, part of pollutants are removed, and microorganisms attached to plant root systems can also degrade organic pollutants, nitrify and denitrify the surface water, adsorb phosphorus and the like, so that the water quality purification efficiency is improved.
Subsequently, the surface water is measured and oozes through the top filter layer, and the filter screen can intercept soil that comes from soil layer and carry, prevents that it from blockking up the filtration pore on the porous ceramic filtration bottom plate.
Then the surface water continues to be measured and permeated through the filler layer, and the first layer is a zeolite layer and a limestone layer, so that nitrogen and phosphorus in the water body can be effectively adsorbed; the second layer is a biochar layer, so that on one hand, pollutants can be directly adsorbed, on the other hand, the growth of plants can be obviously promoted, the capturing capacity of nutrients required by the plants such as organic matters, nitrogen and phosphorus is improved, and the removal of the pollutants is enhanced; the third layer is an active alumina layer which can effectively adsorb fluorine in the water body. Meanwhile, the existence of the filler provides a stable environment for the survival and propagation of microorganisms, and the microorganisms can convert pollutants in the water body into gas or non-toxic and harmless substances through metabolic activities so as to accelerate the purification of the water body.
Finally, the water body passes through the bottom filter layer again, and the surface water quality purification is realized in the process of supplementing the surface water with the underground water.
B. When the groundwater level is higher than the surface water level, the groundwater is used for measuring and percolating the surface water. The groundwater also passes through the bottom filter layer in the seepage measurement process, and the carried soil and large particulate matters are filtered; and then sequentially passing through the activated alumina layer, the biochar layer, the zeolite and lime layer and the top filter layer above, and finally passing through the planting layer to finish the supply of surface water and remove the pollutants such as triazene, phosphorus, arsenic, fluorine and the like in the groundwater in the process.
