Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
Refer to Fig. 1, the life refuse processing method of an embodiment comprises the steps:
S110: collect sink rubbish, then pulverize, obtain pretreatment sink rubbish.
When people clean tableware, kitchen tools, fruits and vegetables at sink, inevitably have some rubbish, such as, melon and fruit peel and swill, fall in sink entrance.In addition, people are when performing cleaning operation, and also can discharge large water gaging to sink, namely sink rubbish comprises solid refuse and waste water.
By the solid refuse in sink rubbish is pulverized, and wash away together along with waste water, like this, can avoid pipeline that the problem of blocking occurs.
S120: collect excreta.
Containing a large amount of anaerobic bacterias in excreta, after mixing with the organic solid waste with abundant nutrition material, good anaerobic fermentation effect can be obtained.Like this, in conjunction with other steps, can effectively utilize anaerobic bacterias a large amount of in excreta.
S130: collect washing sewage and washing sewage, store for future use.
Washing sewage and washing sewage, owing to employing different types of washing agent, also contain more rich nutriment.Such as, for rinsing crashing food rubbish or sink rubbish, and for example, food refuse or sink rubbish is rinsed when pulverizing.
S140: collect food refuse, then crashing food rubbish also passes into washing sewage and washing sewage simultaneously, obtains pretreatment food refuse.
Be appreciated that food refuse is relative to sink rubbish, moisture content less, after being pulverized, viscosity is comparatively large, is unfavorable for flowing, after passing into washing sewage and washing sewage, can obtain mobility admirably, effectively can improve conevying efficiency.In addition, while crashing food rubbish, add washing sewage and washing sewage, on the one hand, can crush efficiency be accelerated, meanwhile, be conducive to being partly dissolved the organic principle in food refuse after pulverizing.
S150: after pretreatment sink rubbish, excreta and pretreatment food refuse being uniformly mixed, obtain pretreatment house refuse.
By pretreatment sink rubbish, excreta and pretreatment food refuse are uniformly mixed, on the one hand, pretreatment sink rubbish and pretreatment food refuse can give pretreatment house refuse abundant nutriment, for anaerobic bacteria survival and reproduction provides sound assurance, on the other hand, excreta can give pretreatment house refuse a large amount of anaerobic bacterias, can decompose pretreatment sink rubbish and pretreatment food refuse more up hill and dale sooner.
S160: pretreatment house refuse is heated, then, after carrying out Anaerobic Treatment, obtains biogas and agricultural fertilizer.Such as, after pretreatment house refuse being heated up, under certain temperature conditions, Anaerobic Treatment is carried out.Such as, described temperature conditions is 20 to 40 degrees Celsius.
Usually, anaerobic fermentation reaction needed temperature higher, by carrying out preheat process to pretreatment house refuse, can accelerate the anaerobic fermentation process that pretreatment house refuse is follow-up, thus obtain the higher biogas of concentration more quickly, use as combustion gas.In addition, the liquid state after anaerobic fermentation and solid-state analyte are rich in nitrogen phosphorus substance, have higher fertilizer, can use as Crop fertilizer.
Above-mentioned life refuse processing method utilizes sink rubbish, food refuse, washing sewage and washing sewage to be rich in organic characteristic, simultaneously, add the excreta containing a large amount of anaerobic bacteria, these rubbish and waste water unification are carried out anaerobic fermentation process, the analyte obtained can completely as combustion gas and Fertilizer application, environmental protection.In addition, above-mentioned life refuse processing method is simple and convenient, is adapted at promoting the use of in family or residential quarters.

In order to improve broken shell effect further, such as, refer to Fig. 8, broken shell grid 970b to be arranged in main tank body in 910, and broken shell cone 960b and broken shell grid 970b is perpendicular.Please refer to Fig. 9, broken shell grid 970b offers some broken shell hole 971b, some broken shell hole 971b are array distribution, the head of broken shell cone 960b wears broken shell hole 971b, by floating or the decline of main tank body 910b liquid level self, crust just can be made to be separated by broken shell grid 970b with liquid level, like this, broken shell effect can be improved further.
Above-mentioned marsh gas fermentation pool 900b is by arranging main tank body 910b, fluid-tight pond 920b, blast pipe 930b, pressure chamber 940b, discharging tube 950b, broken shell cone 960b and broken shell grid 970b, compact conformation is simple, can avoid producing encrustation phenomena, simultaneously, the anaerobic fermentation efficiency of above-mentioned marsh gas fermentation pool 900b is higher, and biogas output is higher.
Above-mentioned Domestic garbage treatment equipment 10 utilizes sink rubbish, food refuse, washing sewage and washing sewage to be rich in organic characteristic, simultaneously, add the excreta containing a large amount of anaerobic bacteria, these rubbish and waste water unification are carried out anaerobic fermentation process, the analyte obtained can completely as combustion gas and Fertilizer application, environmental protection.In addition, above-mentioned Domestic garbage treatment equipment is simple and convenient, is adapted at promoting the use of in family or residential quarters.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
