Description

The treatment process of waste after bamboo fiber processing
Technical field
The present invention relates to a kind of treatment process of waste, especially a kind of treatment process of waste after bamboo fiber processing.
Background technology
At present, along with the development of China's economic construction cause, country improves day by day to sewage disposal and requirement on environmental protection, and many technology for treating industrial waste water are increasingly mature, are able to widespread use.Vast rural area to human and animal excreta and agriculture production in the offal treatment, widely popularize methane-generating pit, to solving the deficiency of rural energy, improve the life of farmers level and cut much ice.This technology is ripe day by day, welcome by vast farmers.But also do not see for the waste after bamboo fiber processing treatment technology.
Summary of the invention
The object of the present invention is to provide the treatment process of the high waste after bamboo fiber processing of a kind of methane gas producing rate.
Technical scheme of the present invention is:
A kind of treatment process of waste after bamboo fiber processing, raw material comprises three parts, be respectively the waste after the bamboo fiber processing: dry material: excrement of animals, by 1: 0.01-0.5: the part by weight of 0.01-0.5 feeds intake, and also adds 30% inoculum and certain quantity of additive of raw material weight; Wherein dry material is the straw through pulverizing, and inoculum is natural pond liquid and in the slag of natural pond any one in domestic sludge, the methane-generating pit, and additive is the bicarbonate of ammonia of raw material weight 0.1-0.5% and is the mixture of the zinc sulfate of raw material weight 50-150ppm; Waste after bamboo fiber processing adding dry material, excrement of animals, inoculum, additive are sent into settling tank add water covering waste and dry material, soak, maintain the temperature at 15-50 degree centigrade of stack retting 3-5 days, obtain intermediate material, again with the intermediate material that configures in intermediate material: dry material: water is 1: the ratio of 1-2: 10-15 adds dry material and water dynamically, and keep 1: the ratio of 1-2: 10-15, put into methane-generating pit or fermentation tower ferments.
Remain dynamic intermediate material in the fermenting process of the present invention: dry material: water is 1: the ratio of 1-2: 10-15, and consistent with the principle that methane-generating pit dynamically ferments.
The treatment process of waste after bamboo fiber processing, it is characterized in that: a kind of treatment process of waste after bamboo fiber processing, raw material comprises three parts, be respectively the waste after the bamboo fiber processing: dry material: excrement of animals, part by weight by 1: 0.1: 0.1 feeds intake, and it is characterized in that: the inoculum and the certain quantity of additive that also add the 25-35% of raw material weight; Wherein dry material is the straw through pulverizing, and inoculum is natural pond liquid and in the slag of natural pond any one in domestic sludge, the methane-generating pit, and additive is the bicarbonate of ammonia of raw material weight 0.2% and is the mixture of the zinc sulfate of raw material weight 100ppm; Waste after bamboo fiber processing adding dry material, excrement of animals, inoculum, additive are sent into settling tank add water covering waste and dry material, soak, maintain the temperature at 15-50 degree centigrade of stack retting 3-5 days, obtain intermediate material, again with the intermediate material that configures in intermediate material: dry material: water is that 1: 1: 12 ratio adds dry material and water dynamically, and keep 1: 1: 12 ratio, put into methane-generating pit or fermentation tower ferments.
The treatment process of waste after bamboo fiber processing, waste after bamboo fiber processing comprise waste liquid, the waste residue behind the bamboo fibers of adding calcium hydroxide or sodium-hydroxide treatment; Scrape the waste of the blue or green bamboo epidermis that produces, the broken leaf of bamboo, broken bamboo shell, the bamboo internal layer that scrapes, mao bamboon branch through pulverizing.
Raw material comprises three parts.The different ratios that changes above-mentioned three class materials in the experiment carries out the anaerobically fermenting test.Experimental temperature remains on 35 ℃, and the time is 10 days, and the inoculation raw material is with liquid natural pond, a kind of natural pond slag, and the inoculation material is 1/3 of raw material.It is as shown in the table that the experiment gas production rate of surveying is converted into factor of created gase.
Waste: dry material: excrement of animals Factor of created gase (m 3/m 3Day)
1∶0.1∶0.05 1.4
1∶0.1∶0.1 1.5
1∶0.1∶0.15 1.5
1∶0.05∶0.1 1.41
1∶0.15∶0.1 1.501
1∶0∶0 1.01
Find out from experimental data: with the increasing of ight soil amount, factor of created gase increases, and be to be to increase DeGrain more than 0.1 when the ratio of reaching, so the optimum proportion that ight soil adds is 0.1.Find out also that from last table along with the increase factor of created gase increasing of dry material, but the degree that strengthens does not have the increasing of ight soil big to the influence of factor of created gase.So the best input ratio of dry material is 0.1.
One) simultaneous test of different vaccination thing
Change different inoculums in the test and test, experiment is under certain material situation, and inoculum is a charging capacity 30%, and fermentation time is 10 days, and leavening temperature is 35 ℃, and it is as shown in the table that measured gas production rate is converted into factor of created gase.
Inoculum Factor of created gase (m 3/m 3Day)
Domestic sludge 0.07
The manure pit muck 1.2
Natural pond liquid, natural pond slag 1.4
The methane spirillum 1.41
Annotate: the methanobacteria inoculum size is 3mmL, and every mmL bacterium number is 1.15 * 10 6
Find out from experimental data: best inoculum is a methanobacteria, but methanobacteria needs laboratory culture, is supplied with difficulty in a large number.So adopt natural pond liquid, the most economical also most convenient of natural pond slag.
Two) inoculum size contrast experiment
Selecting liquid natural pond, natural pond slag in the experiment for use is inoculum, and experiment condition is the same.The experimental result of different vaccination amount is as shown in the table.
Inoculum size Factor of created gase (m 3/m 3Day)
20% 1.30
30% 1.41
40% 1.41
Find out from experimental result: selecting inoculum size for use is 30% to be advisable.
Three) contrast experiment of additive
Additive Additive account for raw material ratio Factor of created gase (m 3/m 3Day)
Bicarbonate of ammonia 0.15% 1.7
Bicarbonate of ammonia 0.18% 1.8
Zinc sulfate 80ppm 1.6
Zinc sulfate 100ppm 1.75
Bicarbonate of ammonia zinc sulfate 0.18% 80ppm 1.9
Bicarbonate of ammonia zinc sulfate 0.18% 100ppm 2.05
Found out that by last table experimental data the best fit of additive is the mixing of bicarbonate of ammonia and zinc sulfate, addition is, bicarbonate of ammonia is 0.20% of raw material, and zinc sulfate is 100ppm.
Comprehensive above-mentioned experiment draws, and optimum process scheme is: raw material ratio is 1: 0.1: 0.1, and best inoculum is: natural pond liquid and natural pond slag, optimum inoculation amount is: 30%, optimum addn is: bicarbonate of ammonia is 0.20% of raw material, and zinc sulfate is 100ppm, and this moment, factor of created gase was 2.05 ((m 3/ m 3Day).
The invention has the advantages that: with the waste after the bamboo fiber processing: dry material: the weight proportion of excrement of animals is reasonable, and has added an amount of additive, has the high characteristics of methane gas producing rate.Another important meaning of the present invention is that the offal treatment after the bamboo fiber processing is clean, has reduced environmental pollution, makes bamboo fiber processing be without fear of an attack from the rear.
