Problems solved by technology

[0002] With the rapid development of China's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. Usually, pig farms first discharge the pig manure into the cesspit around the pig farm. , and then after a certain period of time, a special person will take it away and sell it, but this will cause the surrounding air to be stinky during the backlog period, which not only affects the lives of people around, but also is very unfavorable to the pigs themselves. It is extremely easy to cause the occurrence of infectious diseases; if a large amount of pig manure and urine wastewater is not handled properly, the first is to affect the water quality, because the pig manure and urine contain a large amount of organic matter and organisms, which consume dissolved oxygen in the water when decomposed, and then destroy the ecological balance, such as tap water When the water source is polluted by pig feces and urine wastewater, the water will have a foul smell, which will affect people's drinking; second, it will hinder environmental sanitation, because pig feces and urine will emit a pungent smell, and it is easy to breed mosquitoes and flies, seriously affecting the environment. The quality of the living environment in neighboring communities is harmful to health. Third, it is easy to cause disease transmission. Since pig manure and urine often contain a large number of pathogenic bacteria, if they are not treated and directly used for crop irrigation or directly discharged into rivers, there will be extreme dangers. major disease transmission hazard

Embodiment 1

[0016] A method for recycling pig manure in pig farms, comprising the following steps:

[0017] (1) Collect the pig manure and urine in the pig pen and discharge them into the sedimentation tank, and let them settle freely for 2 days; at the same time, add clean water through the clean water delivery pipeline to dilute to a fixed pig manure content of 18-20%, add sulfuric acid to maintain the pH 5.5-6;

[0018] (2) Extract the pig urine in the sedimentation tank into the fermentation tank, fully ferment for 12 days, add plant ash and ammonia water during the fermentation process to keep the pH at 6.8-7.6, and the fermented pool water can be used for farmland irrigation;

[0019] (3) The pig manure in the sedimentation tank is cleared out on time, dry-wet separation is carried out, and the fixed pig manure is carried out to an odorless fermentation treatment, and the treatment agent used is composed of the following raw materials in weight percentage: 75% chitin, 12% cloves, 5...

Embodiment 2

[0024] A method for recycling pig manure in pig farms, comprising the following steps:

[0025] (1) Collect the pig manure and urine in the pig pen and discharge them into the sedimentation tank, and let them settle freely for 1-2 days; at the same time, add clean water through the clean water delivery pipeline to dilute to a fixed pig manure content of 18-20%, add sulfuric acid Keep the pH at 5.5-6;

[0026] (2) Extract the pig urine in the sedimentation tank into the fermentation tank, fully ferment for 10 days, add plant ash and ammonia water during the fermentation process to keep the pH at 6.8-7.6, and the fermented pool water can be used for farmland irrigation;

[0027] (3) The pig manure in the sedimentation tank is cleared out on time, dry-wet separation is carried out, and the fixed pig manure is carried out to an odorless fermentation treatment. The treatment agent used is composed of the following raw materials in weight percentage: 80% chitin, 10% cloves, 4% mint...

Abstract

The invention discloses a method for recycling pig manure in a pig farm. The pig manure and urine in the pig pen are collected and discharged into a sedimentation tank, and the pig urine is extracted and discharged into a fermentation tank for full fermentation, and the pig manure is timely Clear out, separate dry and wet, and carry out odorless fermentation treatment on the fixed pig manure. The invention can effectively make the collected pig manure into fertilizer suitable for the growth of crops, and at the same time use the separated liquid for irrigation of farmland, which is not only effective It can prevent the random discharge of pig manure and cause environmental pollution, and also improve the economic benefits of pig farms.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment, in particular to a method for recycling pig manure in a pig farm. Background technique [0002] With the rapid development of China's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. Usually, pig farms first discharge the pig manure into the cesspit around the pig farm. , and then after a certain period of time, a special person will take it away and sell it, but this will cause the surrounding air to be stinky during the backlog period, which not only affects the lives of people around, but also is very unfavorable to the pigs themselves. It is extremely easy to cause the occurrence of infectious diseases; if a large amount of pig manure and urine wastewater is not handled properly, the first is to affect the water quality, because the pig manure and urine contain a large amount o...
