Problems solved by technology

At present, nearly 80% of the sludge in the country has not been stabilized and harmlessly treated, and most of it is still sent to urban landfills for simple landfill. Every ton of wet sludge with a moisture content of 80% is buried. It will produce a total emission of 0.5 tons of carbon dioxide and emit a large amount of methane to the environment. Its greenhouse effect is dozens of times that of carbon dioxide, so the secondary pollution is serious
The composition of municipal sludge is relatively complex, the water conte

Example Embodiment

[0049] Example 1

[0050] The sediment produced by urban residents, agencies, schools, units, etc. in their daily life from the municipal pipe network discharged from the sewage treatment process and the floating residue on the surface of the sewage are mechanically dehydrated to a moisture content of 45% , 50%, 55%, 60%, 65% of municipal sludge;

[0051] The waste produced during corn harvesting is crushed, fermented at a high temperature, deodorized, sterilized, dried, ground, and sieved into corn stalk powder with a particle size of -0.18mm;

[0052] A kind of rice bran separated in the process of mechanical processing is heated by steam, and the by-products produced in the process of extracting oil by mechanical pressing method are fermented at high temperature, dried, ground, and sieved to produce a particle size of -0.18mm Rice bran dry cake powder;

[0053] Various animal bones and animal bones separated from food and kitchen waste in the canteens of large hotels, institutions...

Example Embodiment

[0055] Example 2

[0056] Take Example 1 to prepare 70kg of municipal sludge with a moisture content of 50%, 20kg of -0.18mm quicklime powder, 8kg of ferrous sulfate, and 15kg of magnesium sulfate to mix for deodorization, disinfection and sterilization, drying, crushing, and 25kg of corn stalk powder. Bio-organic fertilizer is quickly fermented with 0.6kg of bacterial inoculum, 0.6kg of organic material decomposing agent, 0.3kg of lysine and 25kg of rice bran cake powder. After mixing, it is dynamically fermented in a mechanical container at a high temperature. The fermentation temperature is 80℃. The latter sludge clinker is dried and sieved into a mixed powder with a particle size of -0.18mm for use. Then the mixed powder and bone powder are 18kg, ammonium nitrate 6kg, monoammonium phosphate 8kg, sulfuric acid Potassium 6kg, triacontanol 0.03kg, sodium nitrophenolate 0.03kg and organic activator 0.6kg are mixed evenly with a double-shaft paddle mixing mixer, and then dried int...

Example Embodiment

[0057] Example 3

[0058] Take Example 1 to prepare 65kg of municipal sludge with a moisture content of 55%, 15kg of -0.18mm quicklime powder, 6kg of ferrous sulfate, and 11kg of magnesium sulfate to mix for deodorization, disinfection, drying, crushing, and 18kg of corn stalk powder. Bio-organic fertilizer rapid fermentation strain 0.3kg, organic material decomposing agent 0.3kg, lysine 0.2kg, and rice bran cake powder 18kg are mixed uniformly and fermented at a high temperature in a fermentation tank. The fermentation temperature is 65℃. The sludge clinker is dried and sieved into a mixed powder with a particle size of -0.18mm for use. Then the mixed powder and bone powder 13kg, ammonium nitrate 4kg, monoammonium phosphate 6.5kg, potassium sulfate 4kg, Triacontanol 0.02kg, sodium nitrophenolate 0.02kg and organic activator 0.3kg are mixed evenly with a double-shaft blade mixing mixer to make a bio-organic fertilizer powder product. The nitrogen content of the product is 3.16%. ...

Abstract

The invention relates to a bio-organic fertilizer produced by the use of municipal sludge and a production method thereof. The production method is characterized by comprising the following steps of: using municipal sludge, a quicklime powder, ferrous sulphate, magnesium sulfate, corn straw, a rapid fermentative strain inoculant for bio-organic fertilizers, a decomposing agent for organic materials, lysine, rice bran dry cake, bone meal, ammonium nitrate, monoammonium phosphate, potassium sulfate, triacontanol, compound sodium nitrophenolate, an organic activator and the like as raw materials, uniformly mixing by a twin-shaft paddle mixer, preparing a powder or particles, and packaging to prepare the municipal sludge bio-organic fertilizer product. The product has complete nutrient components, and contains nitrogen, phosphor, potassium and a plurality of trace elements as well as various nutrients such as organic acid which help the growth of crops. The production method has no pollution, requires low cost, has good benefits, and is used to solve the secondary pollution of municipal sludge, protect the environment and save lands. .

Description

technical field [0001] The invention relates to a bio-organic fertilizer produced from municipal sludge. Specifically, it uses municipal sludge and adopts mechanical dehydration to carry out high-temperature fermentation, sterilization, drying, crushing and screening of powder and corn stalks. , rice bran dry cake and bone meal as the main raw materials for the production of bio-organic fertilizers, belonging to the field of waste treatment. [0002] The invention also relates to a manufacturing method of the municipal sludge bio-organic fertilizer. Background technique [0003] Municipal sludge is domestic sewage generated by urban residents, institutions, schools, units, etc. in daily life and mixed sewage generated when it rains. The sewage is discharged to the sewage treatment plant through the municipal pipe network, and the sewage treatment plant adopts physical or chemical methods. Methods The sedimentary substances produced during the sewage treatment process and th...
