Description
Technical field
The present invention relates to a kind of organic refuse treatment appts for coupling hydrothermal carbonization and biochemical reaction principle and processing work
Skill, belong to the fields such as the innoxious and recycling treatment of the discarded object containing organic carbon.
Background technology
House refuse, kitchen garbage, sewage disposal sludge, Sediments, refuse leachate, wooden waste residue, crops straw
Stalk etc. belongs to " organic waste ", and the general character of these discarded objects is containing organic carbon.By taking common kitchen garbage as an example, it
Amount is big, and moisture content is high, is a problem during China's urban garbage disposal.Anaerobic digestion of kitchen wastes is big at present
It is more using the technology such as ferment, make compost.Exist reaction speed is slow, processing not exclusively, produce the problems such as noxious odor and gas.Again
Such as organic waste and refuse leachate, this is an international headache.Recyclable rubbish etc. is all sorted, finally remaining to fill out
One of Main Ingredients and Appearance buried is organic waste.Organic waste is the very big but problem without solution of refuse landfill amount.It is each
Refuse landfill using land limited and quantity of refuse sustainable growth all because perplexed.Organic waste crop root, it is natural
The components such as high organic that refuse leachate caused by precipitation etc. contains, high ammonia nitrogen make it that biotechnology is helpless.Rubbish oozes
Drinking water and the groundwater resources safety in the city on transparent liquid serious threat refuse landfill periphery.With garbage loading embeading amount not
Disconnected increase, the collection and processing of refuse leachate are increasingly urgent.Therefore, it is badly in need of finding suitable China meal of these organic wastes
The technology path and equipment of kitchen garbage as resource processing.
Cracking and hydrothermal carbonization are existing abiotic treating method for organic refuse.Both of which can reduce organic waste biology
Hydrogen, oxygen content in matter, and change into the carbide rich in carbon.Carbonization is cracked to refer in inert gas container, will be organic
(1-20 DEG C/min) is heated to 350-700 DEG C and stops a few houres to a kind of typical carbonization method of several days discarded object at a slow speed；
Hydrothermal carbonization (Hydro-thermal Carbonization；HTC it is) that abandoned biomass is closed water-soluble at 150-350 DEG C
More than 1h is stopped in liquid, is a kind of acceleration pyrolysis for being dehydrated decarboxylation.Compared with tradition cracks carbonization technology, hydrothermal carbonization
With significant advantage：1st, substantial amounts of pretreatment expense has been saved without drying in the high abandoned biomass of processing water content
With；2nd, it is mainly dehydration to chemically react, and carbon fixed efficiency is high in abandoned biomass；3rd, reaction condition is gentle, simultaneously
The exothermic process of dehydration decarboxylation provides part energy for reaction, therefore the technology energy consumption is low；4th, hydrothermal carbonization remains greatly
Oxygen, nitrogen in amount abandoned biomass, carbide surface contain abundant oxygen-containing, nitrogen-containing functional group, can be applied to a variety of necks
Domain；5th, processing equipment is simple and convenient to operate, is strong using scalable section.But in the industry of conventional hydrothermal carbonization technology
Change in application, the processing of output waste water seriously adds the cost of technology, and limits the promotion and application of HTC technologies.

The pretreated material is sent into hydrothermal carbonization retort 2 by charging system 7, carries out hydrothermal carbonization reaction,
The aqueous solid product of generation through cooling system 14 cooling after deliver to biological coal processing system 3, gas be cooled to 50 DEG C with
Crop nutritive water processing system 5 is delivered to after lower.Hydrothermal carbonization reaction design parameter is as follows：Temperature is 80-400 DEG C, pressure
For 0-30 MPa, pH is that 2-9 (passes through C<5 small molecular organic acid regulation pH value, such as formic acid, acetic acid).
3rd, the production of biological coal
The aqueous solid product generated in hydrothermal carbonization retort 2 carries out separation of solid and liquid through solid-liquid separation system, after separation
Solid material by drying system process biological coal (30-200 DEG C of drying temperature), liquid material be cooled to 70 DEG C with
Enter liquid processing system 4 or crop nutritive water processing system 5 after lower (for liquid material, if necessary to enter hydro-thermal
Carburizing reagent tank reuse, then need to be handled into liquid processing system 4, if work will not can be directly entered if reuse
Thing nutritive water processes system).
4th, liquid handling
The liquid material obtained after step 3 separation of solid and liquid is filtered by membrane filtration system, by the non-solubilised state in liquid
Larger molecular organicses are collected, and deliver to and raw material is used as in hydrothermal carbonization retort 2, and filtrate delivers to the processing of crop nutritive water

Biochemical reaction is carried out in thing nutritive water retort 16, the material obtained after biochemical reaction is crop nutritive water, and gas is through collecting
Discharged after processing.The final gas discharge of whole technological process is substantially carbon dioxide.Biochemical reaction major parameter is as follows：Temperature
20-70 DEG C, pH value 3-9 of degree, and add the mixed bacterial being made up of aerobic flora and oxygen flora and anaerobic bacteria flora.Added
Mixed bacterial can be the sludge of sewage treatment plant or the bed mud etc. in river course.
The ratio of gas and liquid need not be controlled in biochemical reaction process, the simultaneous reactions time also without control, leads to
It is often that can be determined according to product purpose 3-200 hours.
The crop nutritive water organic carbon content 1-30% that the present invention obtains, total nutrient NPK0.1-10%, small molecular organic acid
Class (C<5) microorganism based on, aerobic and oxygen mixes group's 1000-1000000000/ milliliters, with reaction time and storage of producing
Time change.
The core of hydrothermal carbonization technology is its economy.The determinant of economy is the reaction temperature of retort, pressure
The processing of caused liquid and the circulation of wherein organic carbon are reacted again in power and catalyst efficiency and course of reaction.Conventional
Hydrothermal carbonization technology, should so as to seriously restrict the technology commercialization just because of above-mentioned reason causes high cost and non-Economy
With.The present invention fundamentally solves the economy problems of hydrothermal carbonization.Various organic wastes are converted into biology by the present invention
Carbon and the crop nutritive water with notable fertilizer efficiency rich in organic matter and nutrition, and any noxious emission is not produced, it is whole
