Abstract

The invention discloses an in-situ anaerobic fermentation integrated device and an urban and rural river and lake water surface algae pollution prevention and control planning method, belongs to the technical field of algae treatment devices, and aims to solve the problems of high construction cost, large occupied area, incapability of moving and unscientific fishing prevention and control planning of a fishing and treatment device in a water algae fishing technology. The device comprises a top film, a bottom film, a feeding pipe, an air guide pipe, a liquid discharging pipe, a slag discharging opening, a floating anti-collision protection device and a traction device; the top film and the bottom film are flexible films; the lower surface of the top film and the upper surface of the bottom film are arranged to form an enclosed flexible air bag, the edges are pressed into a whole, and the air bags are used for accommodating biogas residues, biogas slurry and biogas which are generated by algae fermentation; one end of the feeding pipe is arranged in the air bag, and the other end is outside the air bag; one end of the air guide pipe is arranged at the center in the air bag close to the vertex position and is positioned above the biogas slurry level, and the other end is arranged outside the air bag and is connected with a biogas collecting device; one end of the liquid discharging pipe is arranged inside the air bag, and the other end is arranged outside the air bag; a closed flange is arranged at the slag discharging opening; and the traction device is movably connected with the air bag. According to the scheme of the invention, the device is small in occupied area, low in cost, capable of being moved and folded for storage and scientific in fishing route planning.

Description

technical field [0001] The invention relates to the technical field of algae processing devices, in particular to a mobile algae fermentation device. Background technique [0002] In recent years, with the rapid development of the industrial level, especially under the background of climate warming, serious environmental problems have been highlighted, followed by eutrophication in a large number of waters, and a large number of eutrophic water bodies have grown Algae blooms multiply rapidly, consume a large amount of dissolved oxygen, and reduce the transparency of the water. It is difficult for sunlight to penetrate the water layer, further reducing the dissolved oxygen in the water body, causing fish and shrimp to die, causing serious pollution to the water body and serious damage to aquatic organisms. hazards and pose a serious threat to human health. Recently, the threat of algae blooms to the environment has spawned a variety of coping methods. The main treatment tech...
