Description
Technical Field
The invention relates to an ecological treatment facility suitable for non-point source pollution storage and treatment, and belongs to the technical field of environmental engineering and water treatment.
Background
The living pollution, the agricultural planting pollution and the breeding industry pollution (flower planting, grain planting, livestock and poultry breeding excrement) of villages on two banks of rivers and lakes are main sources of river and lake non-point source pollutants, and the river and lake non-point source pollutants gradually become the most main pollution sources of river and lake water body pollution after being collected through initial rainwater surface runoff and agricultural pollution discharge. Ecological interception is an indispensable ring in the control of the non-point source pollution process, and the existing ecological interception technology plays an important role in the non-point source pollution control. Due to the characteristics of randomness of discharge paths, universality of discharge areas, large and wide discharge amount and the like of rural non-point source pollution, even after source control is implemented, part of pollutants are inevitably transported along with each discharge path, and great influence is caused on the water quality of a downstream water body.
Although a plurality of existing ecological technologies can effectively treat non-point source pollutants, the existing ecological technologies also have limitations respectively. The ecological interception ditch technology can use the terrain of the original ditch, has little newly-increased investment, is easy to be accepted by local people, can store a small amount of non-point source pollution, but has larger space-time difference of nitrogen and phosphorus treatment effects, and has weak storage and treatment capacities when being particularly used for dealing with storm runoff. The ecological T-shaped submerged dam technology is a novel river channel ecological interception technology which is used more in recent years, only needs one-time construction, is high in treatment efficiency, can effectively block diffusion of non-point source pollutants in river branches and creeks, but cannot store incoming water, is weak in treatment capacity, and is not suitable for large river and lake water bodies. The river course paddy field absorption technology can be applied to rural areas with heavy pollution of surface runoff to realize win-win between production and environment, but the problems of soil fertility damage, rice heavy metal exceeding and rice lodging and yield reduction caused by diseases and insect pests are possibly brought in practical application. The ecological buffer zone technology has a good buffer effect on the surface source pollution entering rivers and lakes, but also occupies more land, and cannot be applied in large scale in practical application.
The application of the non-point source pollution ecological treatment technology considers environmental benefits and land economic cost, combines the characteristics of regional environment, and seeks coordination and unification of ecological function, environmental function and landscape function according to local conditions. At present, a plurality of non-point source pollution treatment technologies are used and are all established on the bank of rivers and lakes, but in economically developed areas, the land used on the bank of rivers and lakes is short, and a treatment facility is not easy to be newly added on the bank of rivers and lakes. If the internal positions of rivers and lakes can be utilized, the storage and pollution treatment can be realized on the same vertical surface, and the novel ecological technology for saving land is formed.
