Abstract

The invention relates to a biological purification dam. The biological purification dam comprises a dam body which is transversely arranged in a river lake, wherein gabion filtering layers formed by stacking gabion units are respectively arranged on a river side and a land side of the dam body; the inner part of each gabion unit is filled with biological aggregate; a filtering material filling layer formed by filling the biological aggregate is arranged at the inner side of each gabion filtering layer; the biological aggregate comprises construction waste aggregate and a biological film which is attached to the outer side of the construction waste aggregate and is formed by a microbial agent. According to the biological purification dam disclosed by the invention, microorganisms are produced into the biological film which is attached to the surface of a carrier; the carrier carrying the microorganisms is arranged in a direction of being vertical to a river; a retaining dam is formed in a river channel; when river water flows through a retaining dam layer, the microorganisms in the biological film start to act for performing purifying and pollution cleaning on the river water, so that ammonia nitrogen and organic pollutants in a water body are effectively removed, and the self-cleaning capacity of the river is enhanced; an environment of naturally purifying can be provided for the water body of the river channel, a necessary habitat environment also can be provided for aquatic animals, the eutrophication of the water body is prevented, and a landscape effect of the river channel is improved.

Description

Biological cleaning dam

Technical field

The present invention relates to hoisting connecting piece is and in particular to a kind of structure is simple, the biological cleaning dam of low manufacture cost.

Background technology

With the fast development of national economy, sewage collecting and treatment facility are seriously delayed, cause large amount of sewage directly to enter River, at present most of river become black and odorous water, water standard nor the requirement meeting section examination, therefore need to take measures Administered.

Existing frequently-used river water cleaning treatment measures mainly have that pipeline cuts dirt, Miniature Sewage Farm is built in dispersion and magnetic divides From interim pollution treatment measure these three.But still suffer from pipeline in existing three of the above sewage water treatment method and cut dirty pipe network investment relatively Greatly, city or the intensive region removal amount of other building is larger, the cycle typically need to implement, realize planning with regional planning relatively The deficiency such as long.It is that investment is larger with operational and administrative expenses that treating stations shortcoming is built in dispersion, and occupation of land problem is also not easily solved.Magneto separate Technology is only capable of removing the insoluble pollutant of a part, and the clearance of ammonia nitrogen and total phosphorus is extremely low, and effluent quality remains as bad V class water Matter, much can not meet the water quality requirement of examination, and easily produces substantial amounts of chemical sludge and cause secondary pollution to environment.

Therefore how to make full use of the feature in river course, a kind of construction cost of research and development and operating cost are low, it is simple to implement, Suitable urban rivers and lakes use and the river lake sewage purification system of no pollution is very important.
