Problems solved by technology

The disadvantage is that formic acid and acetic acid are volatile weak acids, and the amount of secretion is too small. As a result, the hydrolysis reaction time is too long, requiring more than 10 hours, which makes the reaction device huge and increases the invest

specific Embodiment

[0010] Below in conjunction with accompanying drawing and production process flow citing embodiment further illustrate the present invention.

[0011]In this embodiment, livestock and poultry manure, crop straw, leaves, branches, humus, organic domestic garbage, activated sludge from sewage treatment plants, industrial fermentation waste residue, and industrial plant hydrolysis residue can be used. If crop straw is used, it needs to be crushed first. One or more than two of the above-mentioned materials are crushed and screened to remove impurities, mixed in a mixer, and then fed into an anaerobic hydrolysis acidification tank. If thermo-anaerobic fermentation is selected, the control temperature is 60°C, and the fermentation time is 4 hours; if high-temperature anaerobic fermentation is selected, the temperature is controlled at 85°C, the fermentation time is 2 hours, and the carbon-nitrogen ratio is controlled at 1:5. After a large amount of organic acid is produced, the hea...

Abstract

A process for quickly treating the organic solid waste (droppings and dung of fowls and animals, straw, stalk, leaf and twigs of tree, etc) by dual hydrolysis' to obtain organic N-C fertilizer includes such steps as regulating N/C ratio, acidifying hydrolysis by medium- and high-temp anaerobic fermenting to generate a lot of organic acid mixture used as catalyst, catalytic hydrolysis at high temp and pressure for obtain micro-molecular nitride and carbide, and catalytic ammonia fixating.

Description

1. Technical field: [0001] The invention belongs to the field of organic solid waste treatment and comprehensive utilization 2. Background technology: [0002] The traditional organic fertilizer method using organic solid waste (including livestock and poultry manure, crop straw, leaves, twigs, humus, organic domestic waste, activated sludge, industrial fermentation waste residue, industrial plant hydrolysis residue, etc.) is Long-term composting fermentation method. Divided into anaerobic fermentation and aerobic fermentation or a mixed fermentation combining the two. The fermentation time is 20 days to 30 days, and when it reaches stabilization, it is decomposed. This method takes a long time, and the result is a large amount of nutrient loss, which becomes greenhouse gas, especially produces malodorous gas and causes secondary pollution, and environmental sanitation is very poor. Because the volatilization of organic matter during the fermentation process produces a la...
