wholesale Biodiesel Production Line Processing of soil contamination of it is reported planned to had arrived to develop thorn level finally, after afterwards air and plan of water pollution prevention and cure are carried out, 10 ” regard “ earth as “ environment main component gets attention fully in ” of 3 big battle. Green of a kind of environmental protection that biology alcohol can make a car not only “ but ” of second birth fuel, fuel alcohol industry still can defy land heavy metal is polluted.
Circumstance of pollution of our country land nots allow hopeful
Our country still has the contaminative land of nearly 30 million hectare at least, include to be close to farmland of 20 million hectare to get heavy metal pollution, land of 5 million hectare suffers oil to pollute, land of 2 million hectare gets mining area pollution, land of 50 thousand hectare suffers solid to discard pile up pollution.
See not hard, problem of pollution of edaphic heavy metal is serious with each passing day, factory area and state of its periphery pollution are relatively outstanding. Differ with the pollution of other organic compound, heavy metal has rich collect sex and very difficult natural degradation, if the heavy metal such as lead and cadmium enters edaphic environment, can long-term save up destroys edaphic ego to purify ability, the “ that makes soil becomes contaminant stores library ” .
Crop is planted on this kind of land, heavy metal can be absorbed by plant root system, cause crop reduction in production, yield the ” of “ poisonous commissariat that contains heavy metal, be like ” of most typical “ cadmium rice. The food that gets heavy metal pollution every year according to estimation has 12 million tons, if these commissariat cannot find an outlet, can have the possibility that flows to table.
Be in China, severe soil contamination case gets for a long time however oversight. In line of business of service of our country environment, the zoology repair company that involves edaphic processing is occupied merely 3.7% , the proportion that the country holds domestic GDP to the investment of this one domain is less than 0.01% , far under Euramerican market the development level of 0.3% .
Industry of biology fuel alcohol but repair heavy metal pollutes land
Why can the plant absorb heavy metal?
To grow and finish whole lifecycle, the plant must be obtained not only a large number of elements (nitrogen, phosphor, Potassium, sulfur, calcic, with manganese) , but material of nutrition of indispensible also minim is like iron, zinc, manganese, nickel, copper and molybdenum. The plant has formed special absorption stage by stage mechanism, assimilate these nutrient substance and store.
But ” of poisonous commissariat of “ digestive ”“
Fuel alcohol is produced brought good news. Use a future life of ” of “ poisonous commissariat to produce fuel alcohol, solve Chen Hua like the past grain question is same. Food alcohol technology is very at present mature, if let new energy company buy “ poison,commissariat ” is used at producing fuel alcohol, solved the outlet of ” of “ poisonous commissariat not only, still produce the fuel alcohol the sources of energy that gave cleanness, it is a favour to farmer, enterprise and whole society. #p#·ÖÒ³±êÌâ#e#
The rehabilitate that heavy metal of alcohol raw material pollutes person
Yuan Longping of academician of Chinese Academy of Engineering thinks, in heavy metal pollution serious area grows super cross rice, apply raw material to be able to transform new gain of science and technology next, its transmit is alcohol of industrial product fuel, this with new thinking it is feasible. It not only drop off stands ground of can low cost the heavy metal content that pollutes land, still can ensure the paddy that is polluted and straw to be digested through industry will produce benefit of enormous economic benefits, society and beneficial result of zoology environmental protection.
Relative to water and air pollution, the case that earth pollutes is more complex, processing difficulty is greater, cost is higher, plant rehabilitate technology of soil because its are safe, cheap and the heat that becomes the world to go up to this domain studies and be developed. If can be transformed further to super cross paddy, breeding goes the metal that suits to be cultivated in contaminative land to exceed tired seeper paddy, on one hand the raw material that efficient production gives fuel alcohol, achieved repair heavy metal to pollute the purpose of land again on the other hand, implementation double be filled with, it is a kind of mode that is worth to be popularized extensively in the whole nation.
Care of can of state of biology fuel alcohol needs more policy to give aid to
Management situation of production of industry of biology fuel alcohol is not at present ideal. As international oil price occurrence bluff type drops, with gas factory price the price of biology fuel alcohol of direct link up with also appeared to dive, and house of price of domestic raw material does not fall high, company of production of biology fuel ethanol is standing unprecedented operation pressure.
Development bottleneck basically has two: It is raw material safeguard, 2 it is market size.
Raw material ensures a respect, at present our country Chen Hua grain uses up almost to use up already, and as commissariat storage level rise ceaselessly, grain of new student Chen Hua is less and less, raw material grain is dried up with each passing day. In the meantime, on grain and the raw material way that are not grain, at present blame food line is held windward, raw material source is so main channel is cassava, sweet broomcorn, straw, and aricultural treatment lave is qualitative. But cassava distance dimensions is cultivated still apart is very far; And sweet broomcorn is in aptly commonly coastal beach besmear is cultivated, although can use resource a lot of, but because district is very dispersive, it is quite difficult still that at present concentration is used. Accordingly, if cannot obtain cheap and effective raw material safeguard, fuel alcohol is just as cook a meal without rice.
Market size respect, after put into production of 4 first domestic fuel alcohol project, the country closes in succession in the province such as Heilongjiang, Jilin, Henan, Anhui promotion uses the alcohol gas that joins alcohol of 10% scale fuel, liaoning, Guangxi expands to visit an area completely further again after, and area of part of Hubei, Heibei, Shandong, Jiangsu, Inner Mongolia. But look on the whole, the zone that alcohol benzine promotion uses popularizes a face narrower, using up gross to go up finite, compare with photograph of motor gasoline gross, solid belong to a drop in the sea. Apparent, alcohol benzine gets policy interpose is stronger, the market is remote not open. #p#·ÖÒ³±êÌâ#e#
Because this is,make the dimensions on domestic fuel alcohol, into the industry, must want construction of form a complete set and the raw material that the industry matchs to supply base; Want to increase alcohol petrolic to popularize strength at the same time, increase demand.
And ” of these “ poisonous land whether use effectively, become useless to be treasure, achieve alcohol of manufacturing organisms fuel and improvement land double winning objective, still need national policy give aid to. Very expect 10 ” can give “ earth biology fuel alcohol bring new policy give aid to.
