1, source reduction.
Treatment mode 1: pig manure treatment is mainly based on reduction. Taking a farm with 3000 pigs as an example, a pig manure dehydrator was installed in the concentrated area of pig manure to separate water from pig manure. According to the calculation that a pig produces 5 kilograms of pig manure a day, 7.5 tons of thin pig manure is produced a day, and about 3 tons of pig manure with 50% water content is dehydrated by a dehydrator. These dry pig manure produced every day are pile together with a forklift, and that strains are sprinkled, and the compost is turned once every four day, and then turned once every day, and the fermentation is finished in about 10- 15 days, thus producing the organic fertilizer raw material. This raw organic fertilizer can be directly put into the land and is the most commonly used source pig manure treatment method.
Advantages: simple treatment method, small investment and good effect.
Disadvantages: there is odor discharged during treatment, and it is more troublesome to dump pig manure with a forklift.
Treatment method 2: pig manure treatment is mainly based on reduction. Taking a farm with 3000 pigs as an example, a pig manure dehydrator was installed in the concentrated area of pig manure to separate water from pig manure. According to the calculation that a pig produces 5 kilograms of pig manure a day, 7.5 tons of thin pig manure is produced a day, and about 3 tons of pig manure with 50% water content is dehydrated by a dehydrator. These dry pig manure produced every day are piled together with a forklift, sprinkled with strains, and turned over once a day with an automatic dumper. After fermentation is completed in about 10 ~ 15 days, the organic fertilizer raw material is produced. This raw organic fertilizer can be directly put into the land, which is also the most commonly used source pig manure treatment method.
Advantages: the treatment method is simple, the investment is small, and the effect is quite good.
Disadvantages: odor is discharged during treatment.
Treatment method 3: pig manure treatment is mainly resource-based. Take a farm with 3000 pigs as an example: a probiotic is sprayed in pig feed every day, so that pigs can eat this microbial agent, and the feces excreted every day have no odor. Install a pig manure dehydrator in the place where pig manure is concentrated that day to separate water from pig manure. According to the calculation that a pig produces 5 kilograms of pig manure a day, 7.5 tons of thin pig manure is produced a day, and about 3 tons of pig manure with 50% water content is dehydrated by a dehydrator. The dry pig manure produce every day is mixed and stac with another organic raw material according to that ratio of 3:1with a forklift, and special small materials and strains are adde with the forklift to be evenly mixed, so that the dry pig manure can be piled into strips for fermentation. It can also be fermented automatically with 10 ton of organic waste by Kaiyang daily processing equipment. Using Kaiyang automatic fermentation equipment, pig manure produced nutritious organic fertilizer on the same day. This is the most advanced pig manure treatment method developed by absorbing the advanced technology of the United States, South Korea and Japan and combining with the actual situation in China.
Advantages: the treatment method is rapid, no peculiar smell is discharged during the treatment process, and the fertilizer yield increase effect is very good.
Disadvantages: large one-time investment.
