In-situ water quality purification device

Abstract

The invention relates to an in-situ water quality purification device. A water quality purification and repair technology mainly targets at urban inland rivers and small and medium-sized rivers in rural areas.The in-situ waterquality purification device comprises a float bowl, an elastic permeable frame, and a permeable pile fiber filter cloth, filler (honeycomb semi-soft filler or fiber-type softfiller), an aerator pipe buckle, a weight iron chain, a positioning ring, a floating block, and a plant system, the in-situ water quality purification device mainly targets at deteriorationand eutrophication of water quality in the urban inland rivers and the small and medium-sized rivers in the rural areas to provide a treatment technology for achieving surface water quality standards. The outstanding features and significant progress of the in-situ water quality purification device are mainly that the in-situ water quality purification effect can be greatly improved; seasonal water level change is not influential; the problem of underwater aerator pipe laying can be effectively solved; the fiber pile filter cloth is used for filtering and absorbing suspended particles in water, and thetransparency of a water body is greatly improved.

Description

technical field [0001] The invention relates to the technical field of water quality purification of urban inland rivers and small rural rivers, and in particular provides an in-situ water quality purification device. Background technique [0002] About 90% of my country's urban rivers are polluted, with water stagnation, mostly in an anaerobic state, poor reoxygenation capacity, serious siltation, low transparency, and even black and odorous phenomena. The environmental capacity and self-purification capacity of the receiving water body lead to serious excess of COD, NH3-N and other pollutants in the river water, damage to the structure of the aquatic ecosystem, sharp decline in biodiversity, and the decline in the ecological function and use function of urban water bodies. The difficulty of restoring ecological functions has increased significantly, and the urban river water environment ecosystem is in an unbalanced state. At the same time, nitrogen and phosphorus pollutant...

AI Technical Summary

Problems solved by technology

At the same time, nitrogen and phosphorus pollutants in urban sewage have not been effectively removed, which has become an important cause of eutrophication in urban water bodies, resulting in the decline or even loss of ecological functions of water bodies. The destruction of aquatic ecological environment has become a major obstacle to the construction of urban ecological civilization. "Water is polluted" and "river is black and smelly" have become environmental problems that many cities are facing urgently to be solved

At present, the river ecological restoration technology is mainly focused on ecological floating islands, constructed wetland heterotopic restoration, bypass interception and filter bed technology, etc. The traditional ecological floating islands have limited water purification effects, are greatly affected by the climate, and the side channels are dislocated. Restoration requires a certain area on both sides of the river, and the promotion and use are limited
