Abstract

The invention relates to a circulation reoxygenation biological decomposition-reinforced riverway water purification system and an implementing method thereof. The system is suitable for water-qualitylong-acting treatment on a still water riverway or an organic pollutant-enriched black and odorous water riverway. The system consists of a muddy sand sedimentation area, a multi-stage water fall reoxygenation unit, a primary sedimentation pool and a riverway biological settling bed treatment unit. The riverway biological settling bed treatment unit consists of multiple groups of biological settling beds which are arranged on the bottom surface of a river bed at intervals along the water flowing direction. After the upstream river is settled and purified by the muddy sand sedimentation area,the riverway water is further decomposed and purified on the biological settling bed treatment unit by biological flora attached to biological fillers; meanwhile, the riverway water returns to the primary sedimentation pool through a water-collecting and water-returning pipe network on the bottom layer, the riverway water is lifted to the multi-stage water fall reoxygenation unit by a water pump,is subjected to biological purification and reoxygenation treatment again and then flows back to the riverway, and so one and so forth, the riverway water is gradually purified, the ecological chain of the riverway is recovered, and the aim of reinforcing the ecological self-cleaning ability of the riverway water is finally fulfilled.

Description

technical field

[0001] The invention relates to a river water quality purification system and its realization method, that is, a river with circulating reoxygenation and enhanced biological decomposition.

[0002] Dao water purification system and implementation method, referred to as "Circulation Reoxygenation Biological Natural purification system (CirculationReoxygenation Biological Natural purification)" or "CRBN system".

[0003] It is suitable for long-term treatment of urban still water channels or black and odorous water bodies rich in organic pollutants. Background technique

[0004] The pollution problem of small and medium-sized rivers in cities and villages is becoming more and more serious. Most of the rivers have poor fluidity, the dissolved oxygen content in the water cannot be effectively supplemented, the self-purification ability of the water body is insufficient, the eutrophication is serious, and even black odor is formed, which affects people's quality o...
