Abstract
The invention discloses a co-production method of biogas by utilizing waste molasses and straw. The method comprises steps as follows: pretreating the straw, proportioning the pretreated straw and the waste molasses, and feeding the materials into a biogas digester for anaerobic fermentation. The invention provides one comprehensive utilization method of the waste molasses and the straw.
Description
Technical field
The present invention relates to a kind of production of biogas, the method for especially a kind of waste molasses and stalk coproduction biogas.
Background technology
Molasses are the by products producing sucrose, if molasses are applied to fermentation industry, greatly will reduce the usage quantitys such as corn, can be cost-saving, and decrease the difficulty of molasses process and reduce Pollution risk.
China is grain big country, and annual stalk is more than 800,000,000 tons, and have and incinerated greatly, not only contaminate environment, also causes huge waste.The principle of biogas fermentation is, by anaerobic bacteria flora, agricultural organic waste is under anaerobic fermented into natural pond liquid and biogas, and biogas main component is methane.Through biogas fermentation, above-mentioned waste is become efficient fertilizer, the efficiency that its nitrogen be rich in, phosphorus, potassium etc. are absorbed by farm crop is up to more than 90%.COMPREHENSIVE CALCULATING, 1 cubic metre of biogas calorific value is equivalent to 2.5 kilograms of timber.Biogas 400-600 cube produced per year by the methane-generating pit of 1 mouthful 8 cubic metres, can save fuel wood 1000-2000 kilogram.Therefore, development biogas technology to the environment protection in rural area and can improve life of farmers quality, and developing agricultural economy all has positive effect.
Summary of the invention
The object of this invention is to provide a kind of method of waste molasses and stalk coproduction biogas.
The method realizing the object of the invention production biogas comprises the following steps:
(1) first stalk is crushed to 1-2cm length by pulverizer, then with dilute hydrochloric acid process 5-10 hour, is then neutralized to neutrality with sodium hydroxide;
(2) will through pretreated stalk and waste molasses mixing, wherein stalk proportion is 20-70%;
(3) mixing stalk and waste molasses are transferred to fermentation vat, 40-50 degree anaerobically fermenting 20-30 days.
The concentration of dilute hydrochloric acid described in stalk pre-treatment is 1-10%.
Described stalk includes but not limited to the crop material such as wheat, corn, soybean, Chinese sorghum, cotton.
Realizing the present invention's molasses used is the tankage that sugar refinery produces sucrose.
Embodiment
Embodiment 1
(1) stalk pre-treatment, is crushed to 1-2cm length by 200kg stalk by pulverizer, then with dilute hydrochloric acid process 5-10 hour, is then neutralized to neutrality with sodium hydroxide;
