Description
Technical field
The present invention relates to municipal sludge, ight soil and changing food waste and merge treatment process, particularly nervous at government fund, municipal sludge, ight soil and changing food waste under need requiring than low investment, less floor space, less working cost merge treatment process.
Background technology
The pollution of municipal sludge, urban night soil and changing food waste is the problem of domestic each city headache always.Municipal sludge has characteristics such as organic content is many, smell big, difficult stacking.Mainly contain multiple treatment processs such as mummification method, half-driedization, compost, anaerobic digestion now.Urban night soil has that water cut is big, organic content is many, controls characteristics such as pathogenic bacteria is many, mainly contains now and municipal wastewater treatment plant combination treatment, methods such as Anaerobic Digestion separately.Changing food waste has big, the characteristics such as the organism fat content is many, complicated component of water cut.The main now technologies such as compost, biological system feed, sanitary landfill, pyrogenic silica, burning disposal that adopt.The traditional technology of above-mentioned Pollutant Treatment all can satisfy the requirement of national environmental protection predetermined process, but there are high, the limitation such as working cost is high, complex management, poor effect, secondary pollution of investment in the individual curing method.
Summary of the invention
The present invention all has the high characteristics of organic content according to municipal sludge, ight soil and changing food waste; Adoption of innovation merges anaerobic treatment process; Simplify processing technological flow; Solve the problem that above-mentioned Pollutant Treatment investment is higher, running cost is too high, the novel process that provides a kind of comprehensive merging to handle, promptly municipal sludge, ight soil and changing food waste merge treatment process.
Treatment process of the present invention is important to be divided into following six unit, pretreatment unit, merges modified unit, anaeration in normal temperature digestion process unit, Digestive system processed unit, marsh gas purifying processing unit, natural pond liquid processing unit.
Described pretreatment unit is divided into three groups of different process according to the pollutent different properties.First group of municipal sludge pretreatment technology adopts the dilution stirring technique, and municipal sludge is carried out the initial adjustment homogeneous.Second group of ight soil pretreatment technology adopts solid-liquid separation, modulation to stir the organic impurity in the ight soil removed, and carry out homogeneous.The 3rd group of kitchen waste preprocessing technology adopts refuse breaking, rubbish filtering, rubbish screw press technology, with inorganic in the rubbish and organic the separation.
In the modified unit of described merging: municipal sludge, ight soil and changing food waste get into the modified unit of merging through after the pre-treatment according to 6: 1: 2 ratios.Preheat through high-temperature steam at the modified unit internal contamination thing of merging, be heated to 40 degrees centigrade, the solid content of pollutent further is adjusted to about 10% simultaneously, satisfies the requirement of follow-up anaerobic treatment.
In described anaeration in normal temperature digestion process unit: after municipal sludge, ight soil and the changing food waste of allotment homogeneous (solid content 10%) preheats; Be delivered in the anaeration in normal temperature slaking apparatus through spiral pump; Various different conditions according to pollutent; Anaerobic environment in the automatic control and adjustment anaeration in normal temperature slaking apparatus makes anaerobically fermenting effect optimization.
Carry out in order to guarantee that anaeration in normal temperature digestion is stable, with the temperature maintenance of the inner mud of anaeration in normal temperature slaking apparatus about 35 ℃ ± 1 ℃.The outside employing of anaeration in normal temperature slaking apparatus hot water is mixed thermic devices it is incubated, and inner machinery and the water-jet of adopting stirs dual mode, and pollutent is stirred.
Anaeration in normal temperature slaking apparatus top is that the biogas that anaerobic reaction produces leaves certain space, and the biogas in the anaeration in normal temperature slaking apparatus is extracted out through the therefrom warm anaerobic digestion device of biogas gas blower top, after purifying, gets into gas holder.Digestive system is discharged by anaeration in normal temperature slaking apparatus top.
In described Digestive system processed unit: municipal sludge, ight soil and the changing food waste anaeration in normal temperature digestion process about through 22 days, Digestive system need carry out solid-liquid separation.Digestive system is through after the centrifuge dehydration, and the solid of generation is that natural pond slag water ratio is about 70%, and liquid is natural pond liquid.
Contain in the slag of natural pond and more comprehensively support part and abundant organism, be mainly polymkeric substance---the humic acid of ring compound, can be used as fertilizer.
COD content is at 2000mg/l～3000mg/l in the liquid of natural pond, NH
4-N content is at 100mg/l～2000mg/l, and total phosphorous is at 1000mg/l～1500mg/l.Can be used as liquid fertilizer is used.
At described marsh gas purifying processing unit: it is biogas that municipal sludge, ight soil and changing food waste merge another important products that anaeration in normal temperature digestion produces; Pressurization gets into desulfurizer to biogas through the air blast machine room; Desulfurization is handled a back part and is supplied with the methane boiler room; Personal as pollutent preheating, the insulation of anaeration in normal temperature slaking apparatus, marsh gas purifying parsing and plant area's heating in winter; A part gets into the marsh gas purifying purification system, and biogas gets into pipeline network of fuel gas in city through purifying the back of purifying, and replenishes source of the gas as the city and uses.
The liquid processing unit in described natural pond: natural pond liquid at first gets into the Anammox integration apparatus and carries out denitrogenation processing.Get into the magnesium salts reaction tank of phosphorus then, in the pond, add Natural manganese dioxide, make phosphorus and magnesium and ammonium radical ion form magnesium ammonium phosphate (MgNH
4PO
4), i.e. struvite.In the magnesium salts settling tank of phosphorus, struvite deposition (well fertilizer).Get into the further dephosphorization of molysite reaction tank of phosphorus at last; In reactor drum, add iron trichloride; Formation tertiary iron phosphate deposition, deposition after the separation and struvite mixing as fertilizer sources are sold (medicine of required Natural manganese dioxide and iron trichloride takes and can reclaim most through magnesium ammonium phosphate and the tertiary iron phosphate of selling).Reach the water drain emission standard through treat effluent.
In a word, minimizing reaches 60% through above-mentioned processing after stain thing, handles back water quality and is superior to national comprehensive wastewater emission standard, goes out clarification of water, and stable, working cost is lower than similar waste water treatment process.
The invention has the beneficial effects as follows:
1. propose first municipal sludge, ight soil and changing food waste are merged processing.Save construction investment, floor space and reduced working cost.
2. anaeration in normal temperature is handled organism is well degraded, and produces a large amount of biogas, not only can produce economic benefit, can also reduce greenhouse gas emission.
3. technical process is simple, level of automation is high, is convenient to the engineering operation management.
4. natural pond slag and natural pond liquid contain a large amount of nitrogen, phosphorus, are suitable as organic fertilizer and are used.
5. merge and handle, make the Pollutant Treatment centralization, be convenient to the environmental exposure management.
