Bioreactor and method for converting solid organic wastes by using bioreactor

Abstract

The invention discloses a bioreactor. The bioreactor comprises bases, wherein feed openings are formed in the top wall of a sealed reaction chamber on the bases; a discharge opening is formed in the bottom wall of the sealed reaction chamber; a stirring shaft is horizontally arranged at the lower part of the inner cavity of the sealed reaction chamber; stirring impellers are arranged on the stirring shaft; a fermentation liquid inlet is formed in the top wall of the sealed reaction chamber; a spray head arranged in the sealed reaction chamber is connected with the fermentation liquid inlet through pipelines; a pressure meter, a temperature meter and a moisture meter are mounted on the top wall of the sealed reaction chamber; an air inlet and a steam inlet are respectively formed in the upper position and the lower position of the left end wall of the sealed reaction chamber; an air discharge opening is formed in the upper part of the right end wall of the sealed reaction chamber; an illuminating lamp is arranged in the sealed reaction chamber; an observation window is formed in the side wall. The invention further discloses a method for converting solid organic wastes by using the bioreactor. In the bioreactor with a completely sealed structure, the growth of saprophagous insects and the aerobic solid fermentation technology are reasonably and effectively combined, so that the treatment of the solid organic wastes is thorough, secondary pollution is not generated, and the additional value of obtained microbial fertilizers, and the additional value of obtained insect feeds are increased.

Description

technical field [0001] The invention relates to the technical field of biology and environmental protection, in particular to a fully sealed bioreactor, and also relates to a method for converting solid organic waste by using the bioreactor. Background technique [0002] With the progress of society and economic development, industries such as catering, food processing, fermentation and livestock and poultry breeding produce a large amount of solid organic waste every day, including kitchen waste, livestock and poultry manure, rotten fruits and vegetables, and residues from the fermentation industry Wait. According to statistics, the kitchen waste generated in Beijing is more than 1600 tons every day; it is estimated that 1 ton per 10,000 people will generate 134,000 tons of kitchen waste per month in the country with a population of 1.34 billion. The problem of manure disposal in livestock and poultry farming is even more serious. With the rapid development of China's li...

Problems solved by technology

[0006] Although the existing methods can basically achieve large-scale and rapid treatment of organic waste, there is still a lot of room for innovation in technology. For example, the existing treatment devices are all open systems, and most of the reactions are carried out in shallow tanks or troughs. , not only the temperature and the water content of the material are difficult to control, but also the odor generated by the growth of insects and the fermentation of the material will cause secondary pollution during the treatment process
