In the fermentation material properties, loose 24-48 hours, days, 15 days of deodorization into fat, not only speed than the planimetric fermentation, and still more effectively prevents the fermentation of hydrogen sulphide, amine such harmful gas and bio-degradability of odorous gases, accord with environmental protection requirement, namely, and can produce good biological fertilizer.
发酵物料在这种松散物料性状下，24-48小时升温、三天除臭、15天左右成肥，不仅比深槽发酵速度快的多，还有效防止了发酵过程中硫化氢、胺气、吲哚等有害、恶臭气体的产生，即符合环保要求，又能生产上好的生物有机肥。
The result of characterization of amphoteric starch indicated that the change was occured in the amorphism portion of the starch configuration, whole crystal framework was not destroyed, its biological degradability was the same to nature starch and no second pollution to environment.
对其结构的表征结果表明：此种两性淀粉仅使淀粉结构中的无定型区发生改变，并未改变整体结晶结构，因此，其生物降解性同天然高分子淀粉一样，可完全降解且无二次污染。
The influences of the polymers on specific methanogenic activities and anaerobic biological degradability are assessed by methods of anaerobic toxicity assay (ATA) and the biochemical methane potential (BMP) test.
