Description

River course black and odorous water body ecological management is with developments reposition of redundant personnel processing apparatus

Technical Field

The invention relates to the technical field of river channel treatment, in particular to a dynamic flow-dividing treatment device for ecological treatment of black and odorous water bodies in a river channel.

Background

Most urban rivers in China have evolved into black and odorous rivers. In many cities in China, organic pollution of river channels is ubiquitous and increasingly prominent, urban sewage directly flows into the river channels, the river reach in cities and towns is seriously polluted, and seasonal or perennial black and odorous water is an urgent water environment problem to be solved in the urban river pollution problem in China.

The so-called black odor is an extreme phenomenon of organic pollution and is caused by the oxygen deficiency of water and the putrefaction of organic matters.

The black and odorous state is an extreme state of the water body, and the characteristics of the black and odorous state are greatly different from other states. The physical and chemical environment of the ecological floating bed is expressed as strong reducing property, the organic and inorganic pollution is extremely serious, the water body has peculiar smell and is not suitable for the survival of aquatic organisms, the aquatic vegetation is degraded and even died, and the phytoplankton, the zooplankton and the benthonic animal only have a small amount of pollution-resistant seeds. Food chain breakage, food net support breakage, serious unbalance of an ecological system structure and serious degradation and even loss of functions.

For the treatment of the black and odorous river channel, the most widely used ecological treatment method at present is used for restoring and treating the black and odorous river channel.

The ecological river regulation means that in a river land control line, on the basis of meeting the basic functions of a river such as flood control, waterlogging drainage, water diversion and the like, the restoration of a river water ecosystem is promoted through artificial restoration measures, and the healthy, complete and stable river water ecosystem activity is constructed.

The present ecological remediation method adopts the duckweed of showy concatenation to accomplish mostly, adsorb the decomposition through the harmful element of plant in to polluting the water, this method can play treatment to slight pollution river course, but unable effectual reposition of redundant personnel pollutes the water, activation treatment effect to black mud in the black and odorous water is not too obvious, and also unable collection reposition of redundant personnel to black mud, lead to the lower condition of the water purification degree after handling, present ecological duckweed fixed mode is mostly the fix with screw, fixed effect is not good, take place to break away from with the river course easily, cause the ecological duckweed of unmanned management, thereby can't play purifying effect to the water, and probably cause secondary pollution.
