Embodiment 1

[0022] Referring to accompanying drawing 1, use central rope 5 to pass through the center of wing plate type packing 3 and combined packing 4, connect them in series, be fixed on the framework 2 of box body 1, form a kind of box-type biofilm self-purifying landscape water body device. The shape and size of the box body can be designed as rectangle, square, circle, etc. according to the actual water body landscape, and the material of the box body skeleton can be engineering plastics or other corrosion-resistant hard materials. The wing plate packing is a cylindrical packing with a wing plate, its diameter and height are 15-20cm, a piece of combined packing with a diameter of 9-15cm is fixed at the lower part of each wing plate packing, and the upper and lower distances of each wing plate packing It is 8-16cm. The central rope is fixed on the fixed frame at the bottom and upper part of the box, and each string of adjacent fillers is staggered.

Abstract

The invention provides a biomembrane reinforced landscape water body self-purification method and the device, belonging to the technical field of water treatment, which is characterized in that a box biomembrane self-purification landscape water body device formed by a plurality of serial swing plate typed fillers and combined fillers is arranged in channels or landscape water body, and then is enclosed with the plastic membranes, forming an independent little water body without water body changing, a mixed-agent of comamonas testosterone A3 and pseudomonas putida is added, and the dose of the mixed-agent is 2 to 5g, the wet weight is /m<3>; after three or five days, the plastic membranes are moved, and when a biomembrane is formed on the filler, the epistrate feeders and zoobenthos are thrown in the device. The invention has the advantages of improving the adhesive animals luxuriantly growth and suspension-feeding with picoplankton through the biomembrane reinforced landscape water body self-purification, reducing the quantity of planktons, increasing the water transparency[s4], and having wide potential application.

Description

technical field [0001] The invention relates to a method and a device for self-purification of landscape water bodies, belonging to the technical field of water treatment. Background technique [0002] The unpolluted water body in the wild environment has a complete water body ecosystem, and each organism plays its own role in the self-purification of the water body. The biofilm attached to solid surfaces such as mud, sand, and pebbles on natural river beds and water banks plays a huge role in the self-purification of water bodies. The biofilm formed on it can quickly degrade organic matter in water and absorb nitrogen and phosphorus. Or the aging and shedding biofilm is the bait of scraping animals and benthic animals, and plays the role of organic matter degrader and transmitter in the aquatic ecosystem. [0003] Urban landscape water body is an integral part of urban landscape diversity, and has become an important place for urban public entertainment, leisure, sightseei...
