a stabilization pond

Abstract

The invention relates to a new type of stable pond, which includes a pond body, which is sequentially divided into a transition zone, an ecological zone, an ecological comprehensive zone and a clear water zone along the direction of water flow, and any two adjacent zones are separated by a diversion wall. There are water outlets on the diversion wall, and any two adjacent water outlets are distributed alternately; a single type of submerged plants is planted in the transition area, ecological area, ecological comprehensive area and clear water area; the buffer transition area and the comprehensive A membrane aeration device is provided in the ecological area; a slag cleaning device is installed between any two adjacent guide rails. Through the structural layout of the stable pond, the reasonable planting of submerged plants and the comprehensive setting of the membrane aeration device, on the one hand, the present invention can quickly remove pollutants such as ammonia nitrogen in water, and reduce the impact of the natural low temperature environment on the system; on the other hand, it can effectively Salvage the dead branches and rotten leaves of submerged plants to ensure the efficient and stable operation of the system.

Description

technical field [0001] The invention relates to the field of environmental pollution control, in particular to a stabilization pond. Background technique [0002] In my country, especially in water-deficient and arid areas, biological stabilization ponds are an effective method for resource utilization of sewage. Over the years, the number of cases of using stabilization ponds to treat sewage has continued to increase. Stabilization ponds rely on natural biological purification functions to purify sewage , The sewage flows slowly in the pond, and after a long period of residence, the metabolic activities of the organisms in the pond are stabilized to degrade the pollutants and purify the sewage. [0003] Through investigation, it is found that due to the slow flow of water in some existing stable ponds, several different types of local microenvironments are likely to be formed inside the stable ponds. The transmission and release of organic matter cannot meet the needs of mi...

Problems solved by technology

In recent years, with the continuous increase in the use of stabilization ponds, the planting of aquatic plants in the project has also evolved from a single species to several species of aquatic plants at the same time. On the one hand, these aquatic plants grow rapidly and compete fiercely in limited water bodies. It is easy to produce the phenomenon of excessive reproduction of dominant species; on the other hand, due to the relatively suitable growth environment and the rapid growth and metabolism of aquatic plants, it is easy to produce residual branches and broken leaves on the surface of the pond body, which requires manual long-term salvage and maintenance. Usually, in order to maintain the stability of the system, it is necessary to A large number of manpower is deployed on duty. In an emergency, a slight mismanagement or untimely disposal will cause the deterioration of the system water quality and cause secondary pollution.
