Embodiment 1

[0032] Example 1, see Figure 2, which shows a method for preparing organic fertilizer using garbage and excrement as raw materials, and the organic fertilizer has not been fermented:

[0033] First, use a closed vehicle to transport garbage and feces to the garbage disposal site, and spray air fresheners when dumping. It is best to use plant-derived air purification fresheners, such as: air purification fresheners developed and sold by Shanghai Weilan Microbiology Research Institute ; and through the suction port, the odorous air is transported to the air purification device to purify and disinfect the air. On the one hand, it is used to reduce dust floating, and on the other hand, through chemical reactions such as polymerization, decomposition, substitution and replacement between plant-sourced air purifiers and some odorous substances, the odorous molecules are improved to lose the odor and become harmless molecules.

[0034] Second, (1). Add polymer flocculant to feces: poly...

Embodiment 2

[0042] Embodiment two, a kind of organic fertilizer preparation method that takes rubbish, feces as raw material:

[0043] The first, the same as the previous embodiment;

[0044] Second, (1) add inorganic coagulant to feces: polyferric sulfate and coagulant spirulina, adding amount: 5 / 10,000 flocculant, 2 / 10,000 coagulant, so that the solids sink and the water It meets the discharge standards and is discharged into the sewage treatment plant for unified treatment, and the solids are press-filtered, and the fecal solids are press-filtered into dung sludge;

[0045] (2) same as last embodiment;

[0046] Thirdly, the manure sludge and the sorted organic waste that can be used for fertilizer are mixed evenly through a horizontal mixer, and the water is properly controlled to make the water content reach 25%, and the pH value is adjusted to 5.

[0047] Fourth, enter the above mixture into the treatment tank through the bucket elevator, and sterilize the garbage and sludge mixtur...

Embodiment 3

[0052] Embodiment three, it is a kind of organic fertilizer preparation method that takes rubbish, excrement as raw material:

[0053] The first, this step is with embodiment one;

[0054] Second, (1) add polymer flocculant to feces: polyacrylamide, the addition amount is 5 / 10,000; add coagulant aid: spirulina, the addition amount is 2 / 10,000, so that the solids sink, and the water conforms to According to discharge standards, it is discharged into the sewage treatment plant for unified treatment, and the solids are press-filtered, and the fecal solids are press-filtered into dung sludge;

[0055] (2) This step is with embodiment one;

[0056] Thirdly, the manure sludge and the sorted organic waste that can be used for fertilizer are mixed evenly through a horizontal mixer, and the water is properly controlled to make the water content reach 28%, and the pH value is adjusted to 2.

[0057] Fourth, input the above mixture into the treatment tank through the bucket elevator, a...

Abstract

A process for preparing organic fertilizer from garbage, excrement and urine includes such steps as flocculating the excrement and urine, press filtering, mixing it with organic garbage, high-temp sterilizing at 120-150 deg.C, adding acidic SiO2 sol at 25-60 deg.C, and stirring.

Description

technical field [0001] The invention relates to a method for preparing an organic fertilizer using garbage and excrement as raw materials. Background technique [0002] At present, the use of garbage and manure to make organic fertilizers has been widely used. People are using garbage, human, poultry and livestock manure to prepare organic fertilizer, often in the form of compost, and let it ferment naturally. The time will be as long as 1-4 months, and there will inevitably be unkilled pathogenic microorganisms in the compost. These pathogenic microorganisms will cause disease-causing disasters and cause serious secondary pollution. [0003] For the selection of garbage, according to some patent documents and domestic garbage sorting applications, bag breaking, crushing, magnetic separation and double-layer cylinder screening are basically used, and because many places in our country are still in the initial stage of garbage sorting, Almost unsatisfactory, some kitchen sw...
