Embodiment 1

[0030] The biogas residue discharged from the anaerobic digestion reactor enters the granulation and fertilizer making part: the exogenous deodorizing strains (Bacillus, Streptomyces, Micropolyspora, Trichoderma and Cellulomonas) are mixed according to the ratio of 1:1:1: The ratio of 1:1 is added to the dehydrated biogas residue, and the mixing amount is 0.5% of the weight of the dehydrated biogas residue. After 4 days of stacking, the odor is determined to be Msl level, that is, the odor can be barely felt, and the deodorization The effect is better. Experimental research shows that after deodorization, the phosphorus-solubilizing and potassium-solubilizing Bacillus (Bacillus.sp) strains isolated and preserved by themselves can be further domesticated and cultivated in biogas residues to obtain phosphorus- and potassium-solubilizing abilities suitable for dehydrated biogas residues. strains. The phosphorus-solubilizing and potassium-solubilizing bacteria obtained through do...

Embodiment 2

[0032] The biogas residue discharged from the anaerobic digestion reactor enters the granulation and fertilizer making part: the exogenous deodorizing strains (Bacillus, Streptomyces, Micropolyspora, Trichoderma and Cellulomonas) are mixed according to the ratio of 3:1:1: The ratio of 1:1 is added to the dehydrated biogas residue, and the mixing amount is 1% of the weight of the dehydrated biogas residue. After 3 days of stacking, it is measured that the odor is MsO level, that is, no odor, so as to achieve odor removal the goal of. Experimental research shows that after deodorization, the phosphorus-solubilizing and potassium-solubilizing Bacillus (Bacillus.sp) strains isolated and preserved by themselves can be further domesticated and cultivated in biogas residues to obtain phosphorus- and potassium-solubilizing abilities suitable for dehydrated biogas residues. strains. The phosphorus-solubilizing and potassium-solubilizing bacteria obtained through domestication were pic...

Abstract

A classifying collecting and treating method for organic refuse and excrement includes: 1) sucking the refuse and excrement into vacuum tubing net; 2) mixing them by vacuum pot and discharging into solid-liquid separated pool, and discharging the solid into anaerobic digesting reactor; 3) concentrating and dewatering the marsh slag discharged, adding deodorized bacterial strain, piling up and deodorizing; 4) adding digesting mud into bacterial strain cultured, culturing, drying and obtaining organic composite bacterial manure; 5) discharging the clear liquid and sewage into anaerobic and oxygen sewage treating unit, and the outlet water discharging into sewage tubing net or water body. Its advantages include lower mud output rate and mud account, and higher mud age.

Description

technical field [0001] The invention belongs to the collection and treatment technology of household garbage or the like. Background technique [0002] The traditional treatment method of urban feces in my country is to collect them from septic tanks and dumping stations through fecal suction trucks, transport them to rural areas on the outskirts of cities, and use fertilizers for farmland and vegetable fields to absorb them. The disadvantage is that parasites are rampant; Pollution to the environment during transportation and loading and unloading. With the rapid increase of urban sewer penetration rate and sewage treatment rate, it has become a main treatment method to discharge feces into sewers together with other sewage and treat them together through sewage treatment plants. The disadvantage is that urban feces are completely treated as waste, and sewage The treatment plant has a large investment and high operating costs; manure is rich in nutrients needed for plant gr...
