Embodiment

As shown in figures 1 to 6, a kind of construction method of city Venous Industrial garden system, comprises the following steps：

A), refuse classification

Domestic waste is sorted, the domestic waste includes biomass class rubbish and fossil class rubbish, the life Material class rubbish includes kitchen garbage, garden garbage, stalk, expired food, dead animal, sludge etc.；The fossil class rubbish Including plastic product, metal, glass, building concrete etc.；Building waste and old is sorted out from the domestic waste Household electrical appliances.

B), biomass separating treatment

To by step A) domestic waste after sorting overstocks lower complete by broken bag, in 80Ma-100Mpa high pressures After separating dry space from moist space, dry rubbish and wet refuse are formed.

C), municipal refuse energy conversion

C1), by step B) in wet refuse and sludge pass through anaerobic digestion formed biogas, nitrogenous filtrate and biological carbon soil； The biogas is formed into natural gas by methane purification technology, used for gas-fueled vehicles；The nitrogenous filtrate is passed through nitrogenous Digestive juice purification techniques forms recycled water and biological carbon soil；The recycled water and biological carbon soil educate tree for potted plant.

The anaerobic digestion comprises the following steps：

C111), sludge is entered behind sludge reception storehouse by carrying out pyrohydrolysis hot water used in system solution by conveying device.It is described Contain excrement in sludge, by high-temperature-hot-water solution, the mobility of sludge can be improved, while realize sanitary disinfecting, improve sludge Stability and dehydration property, improve the factor of created gase and capacity utilization of digestion, at the same reduce digestion sulfur content and The yield of scum silica frost.

C112), by step B) in formed wet refuse by conveying device enter wet refuse receive storehouse.

C113), the sludge after wet refuse and pyrohydrolysis is sent into after blending tank mixing in inflow heat exchanger by feed arrangement, Indirect heat exchange is carried out with recirculated water.

C114 the recirculated water after), exchanging heat is back to pyrohydrolysis system, as the hot water that thermal source is the sludge that sludge receives storehouse Solution provides heat, and the wet refuse and sludge fluid-mixing after heat exchange cooling enter anaerobic digestor, carry out anaerobic digestion reaction.

C115), biogas caused by anaerobic digestion reaction enters methane purification system progress methane purification；Anaerobic digestion is reacted The biogas slurry of formation is dehydrated into dewaterer, is carried out drying and other treatment by solar energy desiccation field to the sludge after dehydration, is formed biology Carbon soil；Filtrate is nitrogenous filtrate, and the nitrogenous filtrate enters nitrogenous digestion liquid purification system after entering dehydration filtrate pond.

The methane purification technology comprises the following steps：

C121), step B) in wet refuse and sludge by biogas caused by anaerobic digestion pass through transfer pipeline enter store up Gas holder.

C1221), the biogas of gas storage holder memory storage is pressurized to 1.5-2MPa by non-lubricated compressor, is preferably 1.7Mpa, use non-lubricated compressor, it is possible to reduce pollution of the lubricating oil to biogas.

C1222), the biogas after supercharging is buffered by conveyance conduit into surge tank, sets surge tank to ensure to tie up Hold biogas in subsequent process and maintain stable operating pressure.

C1223), the biogas in surge tank is completed by first filter, the second filter and the 3rd filter successively Filter three times, the first filter filtering accuracy is 3 microns, and the second filter filtering accuracy is 1 micron, the 3rd filter mistake It is 0.01 micron to filter precision, and maximum remaining oil content content is 0.01ppmw/w after filtering.

C1224 the biogas in surge tank), is passed sequentially through into desulfurizer, dehydration device, decarbonization device, nitrogen rejection facility, de- Desulfurization, dehydration, decarburization, denitrogenation, dehalogenation compound, denitrifying oxide formation day are completed after halide device, denitrifying oxide device Right gas；Wherein, desulfurization is in order to avoid etching apparatus and H2S is poisoned, if biogas combustion releases SO2, H can be compared2S causes bigger Harm, SO2Dew point can be reduced, production sulfurous acid is corrosive after being dissolved in water, it is preferred that using DDS desulfurization technologies；Dehydration is Because if having accumulated water can dissolve H in airway tube2S and corrosion pipeline；Decarburization mainly removes CO2, because CO2Reduce natural pond The energy density of gas, if biogas used needs to reach Natural gas standard or is used as motor vehicle fuel, then just must be right CO therein2It is removed；Preferably, dehydrohalogenation device removes halogenated hydrocarbon using the suction-operated of modified activated carbon, from And reach the purification purpose to pernicious gas.

C1225), natural gas enters natural gas storage facility, the natural gas compressor after compressor compresses are pressurized Driven using the low-pressure gas of large area piston and gases at high pressure are produced in small area piston, output pressure can pass through driving gas Press step-less adjustment；When driving gas to act on gas piston, working piston is achieved with larger output flow with gas drive is dynamic；Institute The phenomenon of biogas pressure deficiency can be improved by stating natural gas compressor, make combustion of natural gas more abundant, firepower is bigger；Compressor can Natural pressure is shortened into 1:200, special sled car can deliver 2000-5000m3 natural gases after compression.

C123), by the natural gas transportation in storage facility to aerating post or gas station, used for gas-fueled vehicles.

The nitrogenous digestive juice purification techniques comprises the following steps：

C131), step C1) in nitrogenous filtrate by conveying device into storage pool store.

C132), the nitrogenous filtrate of storage pool storage is entered after sub- digestion reactor carries out denitrogenation by conveying device and entered Anaerobic ammonia oxidation reactor carries out secondary denitrogenation.

C133), the filtrate after denitrogenation enters sedimentation basin progress sludge settling, forms sludge and clear liquid.

C134), the sludge of precipitation enters dehydration machine room, and the sludge after dehydration is by passing through solar energy desiccation field drying and other treatment Biological carbon soil is formed afterwards, and clear liquid after membrane filtration by forming recycled water.

The recycled water and biological carbon soil are used to potted plant educate tree and comprise the following steps：

C141), take the step C1 of 45-55 parts by weight) formed biological carbon soil and crush after cross 0.1-2mm sieve, obtain Biological carbon soil major ingredient.

C142), take 15-25 parts by weight float stone or the zeolite of 15-25 parts by weight and crushing after cross 0.1-1mm sieve；Take 0.1-0.5mm sieve is crossed after the bentonite of 25-40 parts by weight and crushing；By the float stone to pulverize and sieve or zeolite and pulverize and sieve Bentonite mixing is used as auxiliary material.

C143 20-30 parts by weight step C1 is added after), major ingredient is mixed with auxiliary material) recycled water that is formed stir to be formed it is mixed Compound.

C144), with comminutor by step C143) a diameter of 3-6mm particular biological carbon soil is made in the mixture that is formed Soil conditioner.

C145), by step C144) formed particular biological carbon soil soil conditioner add soil in improve soil property, and Impose recycled water shower to pour, progress is potted plant to educate tree.

C2), by step A) in the building waste, old household electrical appliances and the step B that sort out) in dry rubbish by crushing, disassembling, Sorting/separation, obtains the renewable sources of energy and regrown material, the renewable sources of energy are fired by garbage derivatived fuel technology of preparing Material, specifically comprises the following steps：

C151), by step A) in sort out big part metal, plastics, glass after the construction waste crushing that sorts out.
