Abstract
The invention is a compound microbial inoculant that processes human and animal excreta effectively composed of bacillus subtilis, bacillus licheniformis, geobacillus stearothermophilus, streptococcusthermophilus, geotrichum candidum, aspergillus niger and thermal amylase streptomycete. The microbial inoculum uses metabolism to decompose human and animal excreta effectively in short period of tim e effectively without secondary pollution during process, which extremely reduces environmental pollution brought by human and animal excreta. Meanwhile, the method is sample, low in cost, and saves resources, which can be widely applied to fixed or movable rest rooms, matching the policies of sustainable development.
Description
Technical field
The invention belongs to the ecological, environmental protective field, relate to a kind of effectively compound microbial of handling human and animal excreta.
Background technology
The lavatory plays an important role in daily life, and its admittance every day, accumulation are also got rid of excretory overwhelming majority pollutent in the human daily physiological activity.These excrement dirts have become the main source of pollutent in the sanitary sewage after entering municipal sewage system, also are the important component parts of municipal effluent pollutent.
Along with development of science and technology, many recycling processing methods and the artificial culture microorganism that is applied to wherein of being absorbed in human and animal excreta are all arranged at present both at home and abroad, exist or too single or problems such as complexity, cost height too but these microbial strainss, treatment effect is undesirable can't be promoted the use of thereby cause.
Summary of the invention
The purpose of this invention is to provide a kind of obvious processing effect, do not cause secondary pollution, can overcome the shortcoming of prior art, can be widely used in the processing of fixed or wheeled lavatory.
The present invention is a kind of effectively compound microbial inoculant of handling human and animal excreta, it is characterized in that being made up of subtilis, Bacillus licheniformis, stearothermophilus ground bacillus, thermophilus streptococcus, geotrichum candidum, aspergillus niger and hot streptomyces diastaticus, it is 3: 2: 5 that this seven kinds of bacterial strains bacterium in every gram microbial inoculum is counted the scope ratio: 3: 3: 3: 4.
In the present invention, its using method is: with the biologic packing material thorough mixing, as the treatment agent of ight soil.
In the present invention, the method of spawn culture is: at first subtilis, Bacillus licheniformis, stearothermophilus ground bacillus, thermophilus streptococcus, geotrichum candidum, aspergillus niger, hot streptomyces diastaticus are made successively primary inclined plane cultivation, one-level shake-flask culture, secondary shake-flask culture respectively, thalline is transplanted in solid medium under 35 ℃ of room temperatures cultivated then.
The used bacterial classification of the present invention comes from the contriver from the various avirulent strains that the Chinese Academy of Sciences biological preservation center is bought and process monitoring at different levels department identifies, transferred species rejuvenation regularly and evaluation.
Advantage of the present invention is: the processing efficiency height, used meet microorganism and can utilize multiple organism in the ight soil to ferment and breathe the metabolism that has concurrently, growth temperature has been taken into account the low middle high-temperature stage, realized removing fast of moisture and stink in the ight soil, simultaneously waste can be used as the high-quality fertilizer and uses, and method is simple, realized the resource circulation utilization.
