Biological-ecological purification system for hard river channel

Abstract

The invention discloses a biological-ecological purification system for a hard river channel. The biological-ecological purification system comprises a microporous aeration system and a biological-ecological bed system. The microporous aeration system comprises a microporous aerator, an aeration main pipe and a plurality of aeration branch pipes which are arranged at the bottom of the river channel at intervals; the biological-ecological bed system comprises a plurality of wooden frames, and biological combined fillers and aquatic plants which are mounted on each wooden frame; the multiple wooden frames are arranged in a river channel at intervals in the water flow direction of the river channel. The biological combined filler comprises a plurality of flocculent biological ropes and a plurality of groups of biological balls; a plurality of flocculent biological ropes are connected between the vertical rods on the two sides of the wooden frame at intervals; the plurality of groups of biological balls are vertically arranged between the adjacent flocculent biological ropes in a staggered manner; aquatic plants grow by attaching to the planting barrels, and the planting barrels are hung on the bottom cross rods of the wooden frame through lifting ropes at intervals. According to the invention, organic matters and nitrogen and phosphorus pollutants in water can be effectively removed, and the transparency of water is improved.

Description

technical field [0001] The invention relates to a biological-ecological purification system for hard river channels. Background technique [0002] With the rapid development of the economy, people often ignore the environmental pollution problems brought about by economic development. Many domestic sewage and industrial wastewater are directly discharged into the river, which reduces biodiversity, destroys the ecosystem, and leads to eutrophication of the river water. The problems of pollution and black odor are becoming more and more serious. In recent years, environmental protection issues have gradually received attention, and many scholars, scientific research institutes, and enterprises are studying river improvement technologies. [0003] Common river regulation technologies mainly include physical restoration, chemical restoration, biological restoration and ecological restoration. Among them, physical restoration mainly includes artificial aeration, sediment dredgi...

AI Technical Summary

Problems solved by technology

Among them, physical restoration and chemical restoration can only treat the symptoms but not the root cause. It is difficult to maintain the treatment effect continuously, and the cost is high. At the same time, chemical restoration is likely to cause secondary environmental pollution.
