Embodiment 1

[0022] See attached figure 1 , use the center rope 5 to pass through the center of the wing-type packing 3 and the combined packing 4, connect them in series, and fix them on the frame 2 of the box body 1 to form a box-type biofilm self-purifying device for landscape water. 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 relates to a method and a device for enhancing the self-purification of landscape water body by using biofilm, and belongs to the technical field of water treatment. It puts the box-type biofilm self-purifying landscape water body device composed of multiple strings of wing plate packing and combined packing in the river or landscape water body, and uses a plastic film to enclose the device to form an independent small water body without water body exchange. Throw in a mixed bacterial agent of Comamonas testosteroni A3 and Pseudomonas putida, the dosage of the mixed bacterial agent is 2-5g wet weight / m3; remove the plastic film after 3-5 days, and wait for the biofilm to form on the filler Finally, put scraping animals and benthic animals in the device. In the present invention, while using biofilm to strengthen the self-purification of landscape water, by adding bacteria with strong film-forming ability, the large growth of attached organisms will compete with plankton for nutrients, thereby reducing the number of plankton and increasing the transparency of water bodies. Protecting the environment has broad application prospects.

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, sightsee...
