Method for treating cyanobacteria green plant sewage plant and kitchen waste through photoelectricity and heat synergism

Abstract

The invention discloses a method for treating cyanobacteria green plant sewage plant and kitchen waste through cooperation of photoelectricity and heat, and belongs to the technical field of environmental protection and renewable energy source treatment. After high-temperature pyrohydrolysis / high-temperature disinfection and sterilization, municipal sewage plant organic sludge, municipal organic kitchen waste, municipal other organic matter waste, blue algae and other waste are subjected to high-temperature anaerobic digestion, biogas residue dehydration, high-pressure squeezing and solar drying, finally, resource utilization is carried out, biogas is generated during high-temperature anaerobic digestion treatment, and the biogas is conveyed into a biogas storage cabinet and is collected.Resourceful treatment and the comprehensive treatment process of direct squeezing of a biogas residue dehydrator dehydration high-pressure filter press and solar drying are fully realized, stabilization, harmlessness and reduction of blue-green algae (blue-green algae and blue bacteria), urban green plant waste, sewage plant sludge and kitchen waste can be achieved, meanwhile, waste is turned intowealth, and available biogas and fertilizer are produced.

Description

technical field [0001] The invention relates to the technical field of environmental protection and renewable energy treatment, in particular to a photoelectric-thermal collaborative treatment method for cyanobacteria green plant sewage plants and kitchen waste. Background technique [0002] Blue-green algae (blue-green algae, cyanobacteria), urban green plant waste, sewage plant sludge and food waste collaborative treatment method As organic waste in large lakes and cities, its composition is complex and easily rotten, which is harmful to the environment and human body It is extremely harmful. Therefore, whether blue-green algae (blue-green algae, cyanobacteria), urban green plant waste, sewage plant sludge and food waste can be properly disposed of is directly related to the environmental safety of the Great Lakes and cities and the health of the people. With the rapid development of my country's great lakes and cities, the amount of cyanobacteria (blue-green algae, cyano...

AI Technical Summary

Problems solved by technology

At present, there are only more than 10 anaerobic digestion processes in my country, which are less than 2% of the national cities. Anaerobic digestion can remove blue-green algae (blue-green algae, cyanobacteria), urban green plant waste, sewage plant sludge and low-quality food waste. The organic matter is converted into high-quality energy, but the traditional anaerobic digestion has problems due to the low process level and poor biochemical performance of cyanobacteria (blue-green algae, cyanobacteria), urban green plant waste, sewage sludge and kitchen waste. The problem of low biogas production

[0004] The title is a comprehensive waste treatment process and many other patents. The above-mentioned documents report cyanobacteria (blue-green algae, cyanobacteria), urban green plant waste, sewage plant sludge and kitchen waste treatment processes and equipment, and report cyanobacteria (blue-green algae, cyanobacteria), urban green plant waste, sewage plant sludge and food waste collection, transportation and disposal information platform, reported on cyanobacteria (blue-green algae, cyanobacteria), urban green plant waste, sewage plant Sludge and kitchen waste disposal processes include pretreatment, sorting, anaerobic fermentation, pressure filtration and other processes. The above-mentioned documents all mention different treatment processes, but the specific treatment processes are not appropriate, not only easy The secondary pollution of air has a large amount of emissions and high treatment costs. Therefore, we propose a photoelectric-thermal co-processing method for cyanobacteria green plant sewage plants and kitchen waste
