Garbage Fermentation Broth Of The Impact Of The Growth Of Chinese Cabbage And Soil Characteristics

The nourishment composition density is relatively low , the smell is extraordinarily stench, the suspended substance is very high, the quality is not stable and so on, which are all the character of the biogas fluid from the municipal waste after anaerobic digested. With this poor character, it is inefficientive to made the biogas fluid into liquid fertilizer, attractting mosquito and fly easily, and depositing not easily. So, in this paper, firstly, I put forward to deal the fresh biogas fluid with treatment process of seasoning, stabilize its quality, then use it to plant the cabbage, and at the same time, I study the influence of biogas fluid character, the cabbage growth and the soil characteristic in detail. The study shows:(1) the quality of the biogas fluid will be raised by the treatment process of seasoning, compared to the three condition of the treatment given to the study, the medium is the best , namely the best treatment condition is 15.0mlgas/s.lH2O, six hours every day.(2) Used the original and the treated biogas fluid to handle the vegetable Seeds, both can urge the vegetable seeds to germinate and promote the vegetable bubs to grow, within the scope of certain density. But compared with the two biogas fluid, the vegetable seeds adapt the density of treated biogas fluid is thicker than original one, namely the former thickest is 30% , the later is only 10%.(3) After the irrigation cabbage with different dilution of the two biogas fluid with a certainly period, both can promote the growth of the cabbage, but the best dilution is different: the original biogas fluid is 1:20 , the treated biogas is 1:5, though both can low cabbage's nitrate content, raising the cabbage quality, the treated biogas fluid is better than the original.(4) After Irrigated with the biogas fluid, the soil has the slight accumulation trend of salt alkali and heavy mental, but the soil contents of the wet water, organic quality, total nitrogen and so on have cultivated , expect valid-P has decreased, (6) Irrigated plant with biogas fluid, which can not only eliminate great quantity biogas fluid but also provide a valid exit for processing biogas fluid. used the biogas fluid to the engineering of plant repairing and municipal greening, which is also have a certain engineering foreground and economic benefit.Put together the process and utilization with biogas fluid, since can provide akind of way for processing biogas fluid, also can reuse for the valuable materialwithin the biogas fluid .
