Description
Technical field
The present invention relates to a kind of sewage-treatment plant, especially a kind of wheat straw pulping wastewater treatment zero-emission facility.
Background technique
Currently, various sewage disposal technologies, remove the resource in sewage as pollutant.Moreover, pollutant is again
It cannot completely remove, make pollutant continue to pollute environment, restrict economic development, also generate many social contradications.Therefore, research is set
A kind of wheat straw pulping wastewater treatment zero-emission facility is counted, the pollutant in paper waste is regarded into resource, it is raw all of getting up
Output new product, brings benefit to the people, and is the current technical issues that need to address.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of pulping wastewater treatment zero-emission facilities.
The present invention the technical solution to solve the technical problem is that:
Wheat straw pulping wastewater treatment zero-emission facility, by paper machine room, livestock and poultry farm, anaerobic-aerobic integrating device and agriculture
Field and methane phase equipment composition.The waste water of paper machine room discharge, is filtered by the first rotary filter, will be thick in paper waste
Paper pulp is separated from water, and crude pulp is sent into paper machine room papermaking；Waste water is sent into second tin roller filter, by thin paper pulp and silt and water
Separation, thin paper pulp and silt are sent into processing solid waste methane-generating pit, and the biogas that methane-generating pit generates is sent into boiler combustion.Biogas residue applies agriculture
Field.The filtered water of second tin roller filter, is sent into anaerobic-aerobic integrating device, and the biogas that anaerobic-aerobic integrating device generates is sent
Enter boiler combustion.The water of anaerobic-aerobic integrating device discharge is biogas slurry, and biogas slurry is sent into paddy field, crop culture in paddy field, farming
Object root system absorbs pollutant, that is, nutrients in waste water, reaches the purpose to purify water.Meanwhile biogas slurry has nutrition comprehensive, fertilizer
Power is high；Also have and inhibits the movable function of germ worm's ovum.Therefore, biogas slurry is sent into paddy field, and the crop growth in paddy field is vigorous not
Raw calamity.Crops during the growth process, without spraying insecticide, do not have to fertilize, if do not played herbicide, the agricultural product produced are
Organic farm products.Other aquatic animals can also be breeded fish or cultivated in paddy field, and aquatic animal eats up organic matter i.e. pollutant, reaches
The purpose to purify water.The water that paddy field overflows flows to sedimentation basin, and sedimentation basin top is equipped with immersible pump, and immersible pump is precipitating
Pond top clear water sub-fraction is sent into livestock and poultry colony house, rinses livestock and poultry colony house；Most of clear water sends paper machine room back to and rinses screen cloth, makes
Paper cycling utilization of wastewater zero-emission.
As a preferred solution of the present invention, the feces of livestock and poultry water of livestock and poultry farm (2) is sent into third rotary filter
(17), liquid dung separates, and excrement is sent into solid waste methane-generating pit, the biogas that solid waste methane-generating pit generates, and biogas is sent into boiler combustion；Biogas residue applies
Farmland.Filtered water is sent into anaerobic-aerobic integrating device, and the water of anaerobic-aerobic integrating device discharge is biogas slurry, and biogas slurry is sent into water
Field, the water in paddy field overflow to sedimentation basin, sedimentation basin top is equipped with immersible pump, and immersible pump is the small portion of sedimentation basin top clear water one
It is distributed into livestock and poultry colony house, rinses livestock and poultry colony house；Most of clear water sends paper machine room back to and rinses screen cloth, and paper waste recycles zero
Discharge.
As a preferred solution of the present invention, the exhaust gas of paper plant's boiler emission is sent into methane phase equipment, and it is mixed to generate methane
Gas is closed, methane mixed gas is sent into paper plant's boiler combustion, paper plant's boiler emission exhaust gas, and it is mixed that exhaust gas is sent into methane phase equipment generation methane
Gas is closed, paper plant's boiler waste gas recycles zero-emission.Methane phase equipment working principle: methane phase equipment by diffluence room, cathode chamber,
Anode chamber, methane phase room, separation chamber's composition.Exhaust gas and methane strain, that is, sludge water of boiler emission are respectively delivered to diffluence room,
Diffluence room top is equipped with multiple methane phase rooms, and exhaust gas and sludge water rising respectively enter each methane phase room, at this point, opening electricity
Source, the cathode plate in anode plate and cathode chamber in anode chamber are started to work, and cathode plate generates hydrogen ion, the titanium dioxide in exhaust gas
Carbon and hydrogen ion meet with methane backeria.Carbon dioxide and hydrogen ion synthesizing methane, methane and unreacted under the action of methane backeria
Carbon dioxide and sludge water rise, enter separation chamber from methane phase room；The oxygen generated there are also cathode chamber and anode chamber generate
Hydrogen rise also enter separation chamber.Methane, carbon dioxide, hydrogen and oxygen are referred to as are as follows: methane mixed gas.Because of methane blended
Gas, specific gravity is small, rises naturally, is discharged from separation chamber top；And sludge water is discharged than great from separation chamber bottom, to realize
Methane mixed gas and sludge water content from.
Pulping wastewater treatment is and nitrogenous few, the carbon-nitrogen ratio imbalance because wheat straw is carbon containing more in conjunction with livestock and poultry breeding industry, unfavorable
Anaerobic digestion techniques processing；Again because feces of livestock and poultry is nitrogenous more, and carbon containing few, carbon-nitrogen ratio imbalance, also at unfavorable anaerobic digestion techniques
Reason.The two combines, and rationalizes carbon-nitrogen ratio, is conducive to anaerobic digestion techniques and handles, improve methane tank gas production rate, improves paper waste
Processing and feces of livestock and poultry water treatment efficiency.
Compared with prior art, the present invention first can by the pollutant in paper waste regard resource, all of rise
New product is produced, is brought benefit to the people；Second paper waste, livestock and poultry breeding industry excrement water process, can be realized and recycle zero
Discharge.Third paper plant boiler waste gas recycles zero-emission.4th can also produce organic farm products, aquatic products.5th paddy field
It is exactly wetland, wetland can generate Ecology benefit, improve environmental quality；6th paper plant can be realized power self-support, or even to
Social supply energy source.
In short, organic wastewater generates biogas, biogas paper supply through anaerobic-aerobic integrating device because paper plant ceaselessly supplies waste water
Factory's boiler combustion.Biogas is more day by day, and the exhaust gas that paper plant's boiler generates is more day by day, the first that methane phase device generates
Alkane gaseous mixture is more day by day, and when paper plant's boiler cannots be used up methane mixed gas, methane mixed gas must be energized to society.Also
The Ecology benefit in paddy field.Therefore, paper plant is changed into energy supply family, raising environmental quality family by big power consumer, heavy polluter, realizes
The tidemark of the unified development of environment, economy, social harmony.
