Problems solved by technology

However, if fresh pig manure is directly applied, it will inevitably have negative effects such as crop root damage, disease, and weed damage.
According to statistics, pig farms with an annual slaughter of about 10,000 pigs produce about 12 tons of pig manure every year. If the natural fermentation treatment in the past is used, the storage time will be long and the effect will be poor. pollution

Embodiment Construction

[0017] A kind of harmless treatment process of pig manure, the specific steps are as follows:

[0018] a. Use special drying equipment for dehydration and drying, and make the pig house ventilated smoothly;

[0019] b. Squeeze with an extruder to expand and loosen the pig manure;

[0020] c. Put the pig manure that has been pre-dried to a moisture content of 20% into the pressure window. After 15 minutes of low and medium pressure steam thermal spraying treatment, and then decompressed to normal pressure spraying;

[0021] d. Add chemical agents for treatment, mix evenly, and preserve nutrients;

[0022] e. Add superphosphate, adjust the pH value to about 7.5, and stack for 8-12 days;

[0023] f. Using aerobic fermentation technology, increase the temperature to 70-80°C, and turn over once a day in the morning and afternoon under the action of the turning machine;

[0024] g. The fermentation time is controlled within 20-30 days, and then after about 15 days of stacking in...

Abstract

The invention discloses an innocent treatment technology of pig excrement. The innocent treatment technology of the pig excrement comprises the following steps of dewatering and drying the pig excrement by using special-purpose drying equipment; puffing and loosening the pig excrement; performing heat spraying treatment and pressure reduction spraying on the pig excrement; adding chemical agents in the pig excrement; uniformly mixing the chemical agents and the pig excrement; storing nutrients; adding calcium superphosphate in the mixture; adjusting the PH (potential of hydrogen) value to 7.5 or so; standing for 8-12 days; and performing fermentation treatment by using an aerobic fermentation technology. The innocent treatment technology of the pig excrement is scientific and environment-friendly, is a systematized treatment mode on the pig excrement in batches, creates a considerable economic benefit for enterprises and plays an important role in improvement of a breeding environment and promotion of healthful growth of live pigs.

Description

technical field [0001] The invention relates to the field of manure treatment, in particular to a harmless treatment process for pig manure. Background technique [0002] Pig manure is a good farmyard manure and a high-quality organic fertilizer resource for soil improvement. However, if fresh pig manure is directly applied, it will inevitably have negative effects such as crop root damage, disease, and weed damage. According to statistics, pig farms with an annual slaughter of about 10,000 pigs produce about 12 tons of pig manure every year. If the natural fermentation treatment in the past is used, the storage time will be long and the effect will be poor. polluted. Contents of the invention [0003] The purpose of the present invention is to provide a harmless treatment process of pig manure, which is a scientific and environmentally friendly manure treatment process, and realizes the resource utilization of manure by utilizing limited resources. [0004] Technical ...
