Abstract

The invention discloses a treatment process for biological wastes. The process comprises the following steps of: carrying out dry wet separation of the biological wastes, namely carrying out dry wet separation on household biological wastes to obtain dry wastes and wet wastes; manually sorting the dry wastes, and then sending to recycle; treating the wet wastes, pulverizing, and sending the wet wastes to a pulverizer to pulverize; cooking, namely cooking the pulverized material into a cooking machine so as to achieve the effects of sterilization and fat dissolution; pressing, namely pressing the cooked materials to a presser to obtain residues and oil water; carrying out oil water treatment, namely in an A treatment mode, carrying out anaerobic fermentation on the oil water to obtain methane, and in a B treatment mode, separating oil water by using a separator to obtain oil and water, sending the oil to be used as biological energy sources, such as biodiesel; and carrying out residue treatment, namely adopting the residue as insect feeds, treating the insects obtained by culturing to prepare protein feeds, and utilizing the postbibal feeds of the insects and excrement residues as biofertilizers.

Description

The treatment process of biologic garbage

Technical field

The present invention relates to a kind of processing method of biologic garbage, specifically a kind of treatment process of biologic garbage.

Background technology

House refuse in resident's daily life, its main feature protein and fat content are low, do wet.As house refuse, the treatment process of the kitchen castoff of application just can not be used before the applicant.Because kitchen castoff contains higher protein and fat, its processing method is carried out according to the kitchen castoff characteristics, so be not suitable for the processing of house refuse.Do not have at present a kind of method of good treatment resident's daily life rubbish yet,, solve homology and problem of environment pollution caused simultaneously this kind biologic garbage is handled and utilized.

Summary of the invention

The treatment process that the purpose of this invention is to provide a kind of biologic garbage.

What the present invention will solve is that existing resident's biologic garbage can't effectively be handled and utilize, and solves homology and problem of environment pollution caused.

Treatment process of the present invention is:

One, biologic garbage is done wet the separation

Resident's biologic garbage is done wet the separation, obtains dried rubbish and wet refuse;

Dried rubbish sorts by hand, sends to recycling then;

Wet refuse gets into next step and handles;

Two, wet refuse is handled

1) pulverize, wet refuse is sent into crusher for crushing;

2) boiling, the material that crushes is sent into the precooker boiling, reaches sterilization and grease result of extraction;

3) squeezing, the material after boiling is handled is sent into squeezer and is gone squeezing, obtains slag and profit;

4) profit is handled,

A handles, obtains biogas, and profit carries out anaerobic fermentation, obtains biogas;

B handles, oil-water separator separates, and is separated into You Heshui, and oil is sent to as bioenergy, comprises biodiesel;

5) processing of slag, slag comprise the feed as maggot, earthworm, stratiomyiid insect as the feed conversion of insect, culture the insect that obtains and handle back making protein feed, and food-residue after the insect food and excreta are as the bio-feritlizer utilization.

Advantage of the present invention is: biologic garbage is effectively utilized non-environmental-pollution, energy savings.

Description of drawings

Fig. 1 is a process chart of the present invention.

The specific embodiment

Closed accompanying drawing and specific embodiment below, the present invention is further described.

As shown in the figure, processing step of the present invention is:

One, biologic garbage is done wet the separation

Resident's biologic garbage is done wet the separation, obtains dried rubbish and wet refuse;

Dried rubbish sorts by hand, sends to recycling then;

Wet refuse gets into next step and handles;

Two, wet refuse is handled

1) pulverize, wet refuse is sent into crusher for crushing;

2) boiling, the material that crushes is sent into the precooker boiling, reaches sterilization and grease result of extraction;

3) squeezing, the material after boiling is handled is sent into squeezer and is gone squeezing, obtains slag and profit;

4) profit is handled

A handles, obtains biogas, and profit carries out anaerobic fermentation, obtains biogas;

B handles, oil-water separator separates, and is separated into You Heshui, and oil is sent to as bioenergy, comprises biodiesel;

5) processing of slag, slag comprise the feed as maggot, earthworm, stratiomyiid insect as the feed conversion of insect, culture the insect that obtains and handle back making protein feed, and food-residue after the insect food and excreta are as the bio-feritlizer utilization.
