Biomass carbon source release combination type ecological floating bed water purifying device

Abstract

A biomass carbon source release combination type ecological floating bed water purifying device comprises an ecological floating bed comprising a floating frame and a basket for planting an emergent aquatic plant, a packing groove comprising a groove body and a groove bottom board, and a bottom groove used for planting a submerged plant and internally provided with the packing groove, wherein each of the four corners in a groove body of the bottom groove for planting the submerged plant is provided with a bottom groove suspending ring at the upper end of a bottom groove suspending rod extending out of an upper port of the bottom groove body, each of the four corners in the groove body of the packing groove is provided with a groove body suspending rod extending out of an upper port of the packing groove, a groove body suspending ring at the upper end and the opposite part of the floating frame are respectively bonded by the two ends of an inner cable and an outer cable, the bottom groove used for planting the submerged plant and the packing groove are both made of a board uniformly provided with holes, an artificial water plant or/and a cob is/are suspended at the bottom part of a basket body of the basket for planting the emergent aquatic plant, a zeolite layer, a cob layer, a wheat straw layer and a coal cinder layer are respectively paved between vertical partition boards in the packing groove, and a rope provided with an anchor at the other end is bonded on a vertical floating tube on each of the two sides of the floating frame. The biomass carbon source release combination type ecological floating bed water purifying plant is applicable to open riverways, lakes or landscape water bodies.

Description

technical field [0001] The invention relates to an ecological floating bed water purification device, in particular to a biomass carbon source release combined ecological floating bed water purification device. Background technique [0002] Due to the increase of human activities, the overload of domestic and industrial waste water flows into the river, and the hard revetment and hard bottom also affect the ecological environment of the water area. The problem of eutrophication of water body has been highly valued by people. [0003] At present, the ecological floating beds for the ecological restoration of sewage bodies mainly include floating green island devices, modular floating beds, continuously adjustable floating beds, continuous subsidence floating beds, and combined floating beds. The floating green island device on the water simply uses the floating bed structure to plant aquatic plants on the water surface to directly absorb nutrients and pollutants in the water ...

AI Technical Summary

Problems solved by technology

However, the water body space is not used as a whole, and it is also a purification method that uses aquatic plants to absorb nutrients and pollutants in the water body. The water purification method is single, and only improves some indicators of water quality.

[0004] The most in need of solution and the most difficult problem in water environment governance is the reduction and control of total nitrogen, especially the control of total nitrogen in lakes and urban rivers is very important for improving water quality. Pollution is difficult to solve the eutrophication problem caused by the high total nitrogen in the water environment

[0005] Denitrification and denitrification technology and biofilm technology are mostly used in sewage treatment plants, and it is difficult to extend them to open rivers, lakes or landscape water bodies

[0006] Traditional denitrification technology usually adds liquid nutrients such as methanol to supplement carbon sources, which is too expensive for river treatment, and the effluent is likely to cause secondary pollution, and there is a risk of pollution
