Description

Rural black and odorous water body remediation is with reinforcing water body circulation flow oxygenation's ecological pond
Technical Field
The invention relates to the technical field of water body restoration, in particular to an ecological pond for reinforcing water body circulation flow and oxygenation for rural black and odorous water body restoration.
Background
With the economic development, a new trend of environmental pollution in China appears, and the environmental pollution is rapidly diffused from cities to rural areas. The main expression of rural environmental pollution is sewage pollution, and rural sewage not only causes potential safety hazards in water source areas, but also aggravates crisis of fresh water resources, so that domestic water and farmland irrigation cannot be effectively guaranteed, and the survival and development of farmers are harmed.
The rural pond is generally closed in water body, poor in fluidity and poor in ecological deterioration of the closed water body, and is mainly characterized in that the water quality is black and odorous, because a large amount of organic substances exceed the aerobic metabolism capability of microorganisms, and the excessive organic substances are degraded and consume oxygen, so that oxygen is lacking at the bottom. When the dissolved oxygen at the bottom is lower than 0.2-0.3 mg/L, an anaerobic environment is formed, and the facultative bacteria and the anaerobic bacteria perform anaerobic respiration together. In addition, rainwater and garbage in residential areas enter water bodies in the early stage, a large amount of pollutants are brought, and the water bodies in rivers and lakes are blacked and smelly.
Therefore, solving the problem of black and odorous water is an important measure related to the living environment, safety and health of residents. But the existing closed river and lake treatment modes are simple and rough, can only take effect in a short time and cannot fundamentally solve the problems.
