Abstract

The invention discloses a composite material of marsh gas and a method for preparing the same. The preparation method is characterized in that: manure of livestock and poultry and waste crop stalks, serving as raw materials, are stacked, dried and crushed, added with biological bacteria and an additive and then evenly mixed to obtain the finished product; 70 to 80 percent of manure of livestock and poultry, 15 to 25 percent of crop stalks, 3 to 6 percent of biological bacteria, and 0.001 to 1 percent of additive are mixed; and the manure of livestock and poultry and the crop stalks are stacked, dried and crushed, added with the biological bacteria and the additive, and evenly mixed to obtain the composite material of marsh gas. The stacking time of the crop stalks and the manure of livestock and poultry is 3 to 5 days. The preparation method has the advantages of overcoming the defect of insufficient fermentation materials of marsh gas, providing biological energy with good quality, easily buying raw materials of the manure of livestock and poultry, the crop stalks and the like, and realizing the recycling of wastes, along with low production cost, cleanliness, sanitation and good effect.

Description

Composite material of marsh gas and preparation method
Technical field
The present invention relates to a kind of composite material of marsh gas, particularly relate to a kind of compound material that can be used for methane-generating pit as biogas, also relate to a kind of preparation method of composite material of marsh gas.
Background technology
Biogas be a kind of colourless, have flavor, poisonous, smelly mixed gas arranged, its composition is not only with the kind of fermentation raw material and relative content is different changes, and each is variant because of fermentation condition and fermentation stage.Generally speaking, the main component of biogas is methane, carbonic acid gas and gases such as a spot of hydrogen sulfide, carbon monoxide, hydrogen, nitrogen and ammonia.Biogas is only satisfying just to obtain of fine quality, amount biogas how under microbial growth condition and the methane-generating pit normal running (operation) conditions.Now the fermentation raw material of biogas mainly is to culture livestock and poultry by peasant household to solve, and raw material ratio is more single and not enough, but the trend of culturing is that centralization, mass-producing direction develop, and the rural area labour that goes out is more in addition, and peasant household's breed amount is fewer and feweri.In recent years, country drops into substantial contribution development methane-generating pit for farm household, solve the rural energy problem, owing to culture few, the fermentation raw material wretched insufficiency of peasant household's number, can't satisfy the condition of the normal operation of methane-generating pit, many methane-generating pits are idle, even scrap, the raw material composition is single in addition, gas production rate is not enough, has influenced the development of biogas industry.Therefore, the composite material of marsh gas of research and development scientific formula is the key that addresses this problem.
China's patent on August 6th, 2008 disclosed " anaerobic ferment process of a kind of combined treatment of dejection and stalk " (patent publication No.: CN101235388), earlier ight soil being carried out stack retting handles, mix bait then as vermiculture with the stalk of pulverizing, the earthworm wormcast that produces after the bait of searching for food is added to methane-generating pit anaerobically fermenting output biogas, solve the technical barrier of stalk as the domestic methane tank fermentation raw material, but wormcast is few, and commodity rate is low, is difficult to satisfy large-area application.
Summary of the invention
The objective of the invention is to for overcoming the deficiencies in the prior art, and provide a kind of methane-generating pit that can be used for, solve production and use of marsh gas lack of material, and form merchandise sales, a kind of preparation method of composite material of marsh gas also is provided simultaneously as composite material of marsh gas.
Technical scheme of the present invention is: utilize feces of livestock and poultry, crop waste straw through stack retting, drying, pulverization process, add biological bacteria, additive, mixing becomes product, raw material mixes by following weight part: feces of livestock and poultry 70-80%, crop stalk 15-25%, biological bacteria 3-6%, additive 0.001-1%.
Described biological bacteria is a biogas special bio bacterium.
Described additive is urea or activated carbon powder etc.
A kind of preparation method of composite material of marsh gas follows these steps to carry out:
With feces of livestock and poultry, crop stalk stack retting, carry out drying, pulverizing, add biological bacteria and additive, mixing is mixed thoroughly, makes composite material of marsh gas.
Described crop stalk and feces of livestock and poultry stack retting time are 3-5 days.
The present invention is according to the primary condition of biogas fermentation principle and fermentation, and is through scientific formula, actual in conjunction with producing, the feces of livestock and poultry, crop waste straw that utilize plant add biological bacteria, additive, after fully mixing through stack retting, drying, pulverization process, product is made in the pack of weighing.Add from the methane-generating pit opening for feed during use, add-on is determined according to methane-generating pit size, fermented liquid concentration etc.Extracting 20-30 bucket natural pond liquid from discharge port again after the adding pours from opening for feed.Use this product can solve biogas fermentation lack of material or deficiency, significantly improve the economic benefit of biogas.
The present invention compared with prior art has following effect:
1, solves the biogas fermentation insufficient raw material, the high-quality bioenergy is provided;
2, gas production rate: 〉=0.5m3/kg, factor of created gase improves 30-50%, and is difficult for crust;
3, biological bacteria content 〉=50g/kg;
4, carbon-nitrogen ratio remains on 20-30: 1;
5, raw material such as feces of livestock and poultry, crop stalk is easy to get, and realizes recycling waste;
6, production cost is low, can form commodity, and direct marketing uses for vast biogas peasant household;
7, peasant household uses product of the present invention convenient, and sanitation and hygiene are effective;
Embodiment
Embodiment 1: with feces of livestock and poultry, as chicken manure, cow dung or pig manure etc. 70%, crop stalk 24%, it is long to cut 3-5cm, crop stalk and feces of livestock and poultry stack retting 5 days, carry out drying then, water content is controlled at≤30%, again crushing screening (10-20 order), add biological bacteria 6% (Foshan City gold certain herbaceous plants with big flowers plant nutrition company limited produces) and 0.001% activated carbon powder, mixing is mixed thoroughly, makes composite material of marsh gas, and metering packing becomes commodity.When promoting the use of, suitably add this product according to methane-generating pit size, natural pond liquid concentration, the normal methane-generating pit of aerogenesis can add this product 40-60kg (the 10-15 natural gift add better effects if 2 times at interval); Gas production rate is few, the methane-generating pit of insufficient raw material can add this product 60-100kg (the 7-10 natural gift add for three times at interval).Must add this product and take out 20-30 bucket natural pond liquid from discharge port and pour opening for feed from opening for feed at every turn.
