Cyanobacteria integration treatment method and equipment

Abstract

The invention relates to a cyanobacteria integration treatment method and cyanobacteria integration treatment equipment. The method comprises the steps of pressurization, flocculation, dehydration, modification, advanced dehydration, pyrolysis carbonization and the like. The equipment comprises a first cyanobacteria slurry tank, a pressure tank, a second cyanobacteria slurry tank, a dehydrator, acyanobacteria ooze hopper, a cyanobacteria ooze modifying device, an electrodialysis dehydration device, a pyrolysis oven and a controller. A high-pressure sludge pump is arranged between the first cyanobacteria slurry tank and the pressure tank, an adjustable pressure one-way valve is arranged between the pressure tank and the second cyanobacteria slurry tank, and the second cyanobacteria slurrytank communicates with the dehydrator. A flocculant adding opening is formed between the sludge pump and the dehydrator. First spiral conveyors are arranged between the cyanobacteria ooze hopper and the cyanobacteria ooze modifying device, between the cyanobacteria ooze modifying device and the electrodialysis dehydration device and between the electrodialysis dehydration device and the pyrolysisoven respectively. The first spiral conveyors are connected with the controller through wires. Through the method and the equipment, the volume of treated cyanobacteria can be greatly reduced, effectson a surrounding environment are avoided, and secondary pollution is eliminated.

Description

technical field [0001] The invention relates to an integrated treatment method and equipment for cyanobacteria. Specifically, it is an integrated treatment method and equipment for deep dehydration, drying and electrodialysis pyrolysis treatment of algae water salvaged from rivers and lakes. Background technique [0002] With the rapid development of my country's economy in recent years, the pollution and eutrophication of rivers and lakes are becoming more and more serious. All major lakes in the country have produced different degrees of algal blooms. A large number of blue-green algae outbreaks in summer have seriously threatened the residents along the lake. drinking water is safe. In order to solve the problem of water pollution, various scales of water pollution control have been launched in various places to curb the further deterioration of water bodies. Some areas, such as the Taihu Lake area, have carried out large-scale blue-green algae salvage projects to ensure...

AI Technical Summary

Problems solved by technology

Due to the treatment of large-scale sedimentation and concentration tanks, the volume of algae mud after preliminary dehydration is relatively large and is still piled in the yard, so that in the summer when cyanobacteria are produced, the initially dehydrated cyanobacteria are in an open environment, and they are easy to rot and smell. Affect the surrounding air quality

And because in some areas, the salvage amount of blue-green algae is huge during the peak period, there is no suitable place to pile up algae mud, and the situation of stacking everywhere often happens, seriously affecting the environment

In case of heavy rain, these pollutants will return to the water body, causing secondary pollution to the water body
