Abstract

The utility model provides a dirty utilization of resources system of excrement, including solid -liquid separation drying device, equalizing basin, high -efficient anaerobism purifying column and concentrated recovery unit, solid -liquid separation drying device carries out solid -liquid separation from the excrement dirt of plant in the future to drying the solid -state residue of after -separating and discharging, the liquid excrement dirt of isolating is passed through to congeal the wadding and is precipitated back row income equalizing basin regulation, link to each other through the pipeline between equalizing basin and the high -efficient anaerobism purifying column, high -efficient anaerobism purifying column ferments liquid excrement dirt and generates marsh gas, the heating evaporation concentration is carried out in the liquid excrement dirt that concentrated recovery unit will pass through after the fermentation, liquid excrement is dirty to form the fertilizer through congealing to wad a quilt with cotton to precipitate. The utility model discloses with hierarchical cow bed bedding and padding, fertilizer, marsh gas, the liquid fertilizer of progressively handling into of excrement dirt, to handle the fertilizer and the liquid fertilizer that produce and can be used to farming, the marsh gas accessible of production is purifyd and is become the natural gas or directly generate electricity through marsh gas, and the dirty high -usage of excrement is little to the environmental impact.

Description

A kind of excrement dirt utilization of resources system

Technical field

The utility model is related to treatment for cow manure system, and in particular to a kind of excrement dirt utilization of resources system.

Background technology

With the progressively expansion of farming industry structure, the animal excreta dirt that cultivation is produced becomes one and puts the axe in the helve greatly, livestock and poultry Excrement dirt anaerobic fermentation can produce a large amount of biogas slurries, belong to high pollution thing, it is impossible to be directly discharged in environment, be set by building later stage treatment Apply carry out it is up to standard treatment and cause Construction and operation expense to greatly increase, therefore there are problems that it is serious dissolve, in fact, in biogas slurry Contain abundant nitrogen, phosphorus, potassium, amino acid, abundant trace element, B family vitamin, various hydrolases, organic acid and humic acid It is good organic fertilizer Deng bioactivator, stimulates plant growth, enhancing crop anti-adversity and improvement product quality.Natural pond Liquid can use the secondary utilization for being capable of achieving resource as organic fertilizer.But often there is neighbouring farmland digestion capability deficiency, winter The utilization spatial and temporal distributions inequality such as utilization is small, long distance transportation high cost and economy problems, while having with chemical fertilizer or commodity Machine fertilizer is compared, and every nutrient concentration is relatively low in biogas slurry, and the enthusiasm that peasant utilizes is not high, limits to a certain extent The feasibility biogas slurries that agricultural is dissolved are dissolved the difficult popularization that also directly limit biogas engineering and the operation of long-term efficient stable.Cause This, how by the dirty rationally treatment of excrement, it is a problem anxious to be resolved to turn waste into wealth.

Utility model content

Based on above mentioned problem, the utility model purpose is to provide a kind of excrement dirt utilization of resources system, can be by excrement dirt point Level is progressively processed into ox bed padding, organic fertilizer, biogas, liquid fertilizer, final qualified discharge.

For problem above, there is provided following technical scheme：A kind of excrement dirt utilization of resources system, including separation of solid and liquid is dried Equipment for drying, regulating reservoir, efficient anaerobic purifying column and concentrating recovery device；The separation of solid and liquid drying unit is connected with regulating reservoir, Excrement dirt from plant is carried out separation of solid and liquid by the separation of solid and liquid drying unit, and the solid residue after separation is dried into row Go out, the liquid excrement isolated is dirty to be adjusted by entering regulating reservoir after flocculation precipitation；The regulating reservoir and efficient anaerobic purifying column it Between by pipeline be connected, the dirt of liquid excrement is carried out fermentation and formed methane by the efficient anaerobic purifying column；The concentrating recovery device It is connected with efficient anaerobic purifying column, the liquid excrement dirt after by fermentation is carried out heating evaporation concentration by the concentrating recovery device.

In said structure, separation of solid and liquid drying unit is arranged to regulating reservoir liquid excrement dirt after excrement dirt is separated, and is isolated Solid-state excrement is dirty to turn into ox bed padding by drying；The concentrating recovery device is heated the excrement dirt of completion of fermenting by heating Evaporation, makes its concentration form liquid fertilizer, evaporates the moisture for producing by that can meet emission compliance after the treatment of biological bacteria facture It is required that.

The utility model is further arranged to, and also including air accumulator, the air accumulator is mutually used in conjunction with efficient anaerobic purifying column In the biogas for collecting generation in efficient anaerobic purifying column.

In said structure, liquid excrement is dirty fermented in efficient anaerobic purifying column after storage is collected by air accumulator, conveniently after Biogas is used to purify by the phase turns into natural gas or for marsh gas power generation.

The utility model is further arranged to, and flocculation precipitation is provided between the separation of solid and liquid drying unit and regulating reservoir Pond, the liquid excrement dirt forms organic fertilizer by flocculation precipitation.

In said structure, because there is more impurity in the liquid excrement dirt after separation of solid and liquid, it is therefore desirable to by flocculation precipitation Pond flocculation precipitation precipitates solid content, and the liquid excrement soiled ends after precipitation produces biogas after being reconciled by regulating reservoir for fermenting, Fixture after precipitation can work as organic fertilizer and use.

The beneficial effects of the utility model：Excrement dirt can be turned waste into wealth, classification be progressively processed into ox bed padding, organic fertilizer, Biogas, liquid fertilizer, final qualified discharge, the organic fertilizer and liquid fertilizer for processing generation can be used for agricultural planting, efficient anaerobic Purifying column, three days fermentation periods, the biogas of generation can be by the way that purification is as natural gas or is directly generated electricity by biogas, excrement Dirty utilization rate is high, and effect on environment is small, and every section of recycling simultaneously, all in the concentration of reduction sewage, then is fermented with biological bacteria The cost for the treatment of is lower, and equipment investment is less, this set system equipment overall cost of ownership than it is existing it is few invest 1/3, income 5 times with On.
