Description
Technical field
The invention belongs to technical field of sludge treatment, in particular, belong to food garbage and mixed the equipment that rear anaerobically fermenting generates methane gas with mud.
Background technology
Food garbage is the most general refuse produced in the daily life service of city, it is one of main source of domestic waste, its main component is the organism such as starch food, vegetable fibre, animal proteinum and fats, there is the high and grease of water ratio, salt content is high, easily corrupt smelly, be unfavorable for the characteristics such as common dumper transportation.This class rubbish is as caused great harm without classification special treatment meeting to environment.
Food garbage is processed the mode that roughly is divided into mechanical disintegration, compost, biological feed processed and anaerobically fermenting.The mode of Anaerobic Digestion food garbage be take as main in European Union member countries especially Germany, in Japan, similar application is also arranged.Food garbage is after all kinds of impurity is removed in pre-treatment, and the residue organic matter mixes other biodegradable organic waste merging such as municipal sludge, feces of livestock and poultry and carries out anaerobic digestion, and the biogas of generation is implemented the generating online and used as resources circulation.
Summary of the invention
The present invention, in order overcoming the above problems, to have provided a kind of food garbage and mud mixing anaerobic and has processed the skill system.
The system for anaerobic treatment that a kind of food garbage mixes with mud, it is characterized in that: native system comprises food garbage preprocessing part and anaerobic digestion part;
The food garbage preprocessing part comprises food garbage storage tank, material conveyor, broken apart device, slurries storage tank, slurries lift pump;
Anaerobic digestion partly comprises that sewage sludge feed pipe, food garbage feed-pipe, anaerobic jar, agitator, companion's hot charging are put, the gas storage cryopreservation device;
The food garbage storage tank is arranged on above material conveyor, and broken apart device is arranged on below material conveyor, and the slurries storage tank is arranged on below broken apart device, and the slurries lift pump is arranged between slurries storage tank and food garbage feed-pipe;
The sewage sludge feed pipe is connected with anaerobic jar jointly with the food garbage feed-pipe; The gas storage cryopreservation device is arranged on the top of anaerobic jar; Companion's hot charging is put the side that is arranged on anaerobic jar; Agitator is arranged on the bottom of anaerobic jar.
The present invention is usingd food garbage and municipal sludge as producing the hydrogen substrate, and food garbage and municipal sludge ratio are 1:3-4, and municipal sludge proportion in substrate is higher, has greatly improved the utilization ratio of municipal sludge.The present invention can bring up to 40-80% by degradation effect of organic compound, so just can obtain treatment effect preferably.After food garbage and municipal sludge are mixed, can obtain better biogas fermentation effect.The natural pond slag that food garbage and municipal sludge mixing secondary fermentation produce can be for making biomass fertilizer.
Final residue (being the natural pond slag) directly as fertilizer sources returns farmland or grassland use, or makes organic fertilizer after aerobic compost.Being mixed with of food garbage and municipal sludge is beneficial to the unfavorable factor that balance and stability digests the nutritive ingredient of medium and eliminates single material, can promote the process of anaerobic digestion.Food garbage and mud Mixed fermentation can effectively overcome the impact of food garbage basicity and nutrition deficiency after processing; Can effectively overcome the impact of grease; But the impact of active balance salt.By the composition analysis before and after fermentation, can find out the ammonia nitrogen substances content in fermentation secondary fermentation liquid.Food garbage (30%) organic part of water ratio (8-9.6%), the butt of mud (6-8.4%) that be mixed before fermentation; Be mixed water ratio (9-5.3%), the butt of mud organic part of (5-0.3%), ammonia nitrogen (1749mg/L), total nitrogen (1953mg/L) of food garbage (30%) after fermentation.
The present invention is compared with prior art: have energy-conserving and environment-protective, energy utilization rate high, can develop the advantage such as biomass energy, effectively solved the difficult problem that food garbage is processed.
The accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the system for anaerobic treatment that mixes with mud of food garbage.
Embodiment
Be the structural representation of the system for anaerobic treatment that mixes with mud of food garbage of the present invention as shown in Figure 1, the system for anaerobic treatment that food garbage of the present invention mixes with mud comprises that food garbage storage tank 1, material conveyor 2, broken apart device 3, slurries storage tank 4, slurries lift pump 5, sewage sludge feed pipe 6, food garbage feed-pipe 7, anaerobic jar 8, agitator 9, companion's hot charging put 10, gas storage cryopreservation device 11.
Food garbage and municipal sludge are transported to treatment plant by carrier vehicle, food garbage enters food garbage storage tank 1 after discharging, opening cutter type gate valve is transported to millerator 3 by the material in the rubbish storage tank by material conveyor 2 and carries out fragmentation and expression separation, impurity and food garbage are separated, slurries after processing partly enter slurries storage tank 4, impurity partly enters material slag chute car, slurries enter anaerobic jar 6 through slurries lift pump 5, municipal sludge enters anaerobic jar 6 by sewage sludge feed pipe 6, and slurries mix with municipal sludge and carry out Anaerobic Digestion.Food garbage and mud are after the mesophilic digestion about 20 days, and the biogas of generation is made fuel and used; The base-material that the food garbage of digestion and mud can be done Nutrition Soil or fertilizer uses.
The separation efficiency of broken apart device 3 of the present invention is very large on the working efficiency impact of system, separates the bad direct organism rate of recovery and the mass transport of affecting.
Anaerobic jar 8 of the present invention can be processed the food garbage of solid content 10 ~ 12% and the material that municipal sludge mixes, and utilizes its unique agitator 9 and companion's hot charging to put 10 and makes the reaction mass homogeneous, eliminates the impact of grease in food garbage, the production capacity maximizing efficiency.The present invention can use two agitators 9 to be symmetricly set on the bottom of anaerobic jar 8, two agitators are worked simultaneously, the mud feed liquid of anaerobic jar 8 tank base is rotatablely moved along the certain orientation hoop, the feed liquid of anaerobic jar 8 tank base can drive the feed liquid of tank body middle and upper part along same direction rotation simultaneously, realized that mud feed liquid integral loop stirs to solid, feed liquid is mixed more even, improved the container utilization ratio of anaerobic jar 8 tank bodies; Can also be equipped with the assisting agitating apparatus such as water-jet pump, can obtain better mixing effect simultaneously.Such overall flow is conducive to the removing of the mud feed liquid in tank body, and guarantee the homogeneity of mud in tank body (as slaking apparatus levels temperature inequality fermented liquid can thoroughly not be with frowziness because of degraded).The feed liquid that makes tank base when the common work of two agitators 9 to sluggish flow, can allow water-jet pump 3 to make up water in tank body according to certain directional ring simultaneously, so just more is conducive to the mobile of feed liquid in tank body.
