Help Gaotai County to realize the utilization of livestock and poultry waste resources

With the popularity of the concept of green development, the harmless treatment and resource utilization of livestock and poultry manure has become a common concern of the people. Improper handling of manure in livestock and poultry breeding will cause agricultural non-point source pollution, and if handled properly, it will become a degradable and usable valuable resource.

It is understood that in Gaotai County, Gansu Province, the number of livestock and poultry breeding reached 2.82 million (only), in the face of so much need to deal with livestock and poultry manure, how to effectively use waste into treasure, promote livestock and poultry waste treatment and resource utilization, Gaotai County agricultural department has been a lot of trouble, but also think of a lot of ways.

The agricultural department of Qingdao and the agricultural department of Gaotai County launched a professional technical exchange, jointly discussed and shared the treatment technology of livestock and poultry manure, and the two sides carried out in-depth discussion and demonstration on the practical application and transformation of membrane composting technology in the whole county to promote the utilization of livestock and poultry manure resources. The agricultural department of Gaotai County finally selected Qingdao Zhonghai Environmental Engineering Co., Ltd. as the partner of the project to promote the utilization of livestock and poultry waste resources in Gaotai County after investigating and comparing a number of domestic membrane composting technology enterprises.

How to realize the harmless treatment and resource utilization of livestock and poultry manure

After learning the geographical location and specific conditions of Gaotai, Qingdao Zhonghai environment focuses on the resource utilization of livestock and poultry manure returning to the field, summarizes and promotes the mode of farmers + manure treatment + returning to the field, and explores the establishment of a virtuous cycle chain of "breeding, composting, fermentation and planting". Comprehensively guide enterprises and farmers to adopt aerobic fermentation process for manure in pig, chicken, cattle and sheep livestock and poultry farms, and use NCS membrane compost and ECS environmental protection compost box to convert manure into organic fertilizer and return it to the field for recycling, or manufacture it into commercial organic fertilizer for sale, so as to achieve the purpose of harmless and resource utilization in the whole process of manure treatment.

In order to promote the virtuous cycle of agricultural ecological environment and clean production of animal husbandry, and realize the sustainable development of rural economy and livestock breeding, Gaotai County actively strives for and vigorously implements the whole county project to promote the utilization of livestock and poultry waste resources. With the support and cooperation of various departments of the county government, the county Agriculture and Rural Bureau is responsible for the promotion of the project. According to the treatment path of "source reduction, process control and end utilization", the utilization and treatment mode of manure collection and return to the field, solid manure composting, sewage fertilizer and other utilization and treatment modes are promoted. Construction of livestock and poultry manure collection, storage, treatment, utilization and other links of infrastructure.

NCS and ECS help realize the cycle development of combined cultivation

We have learned that Landao Town is located in the outskirts of the city and is a large town of livestock and poultry breeding. The main livestock and poultry breeding capacity is 101,900 live pigs, 26,800 beef cattle, 159,900 mutton sheep, 278,300 poultry, and the annual manure production capacity is 451,300 tons. The previous natural fermentation and return method is limited by seasons and facilities and equipment, and the fermentation is incomplete. Direct return to the field will pollute the soil of the field.

Combined with the situation of the whole county to promote the project, two forms of NCS membrane compost and ECS environmental compost box were used respectively. Laneway Town animal husbandry and veterinary workstation fully cooperate with the county animal husbandry station and Qingdao Zhonghai Environmental Company technicians to install and debug the NCS membrane stacking machine and ECS environmental compost box.

During the installation and commissioning, the person in charge of the animal husbandry and veterinary workstation in Landao Town and the farm carefully learned the NCS membrane compost fermentation technology. The technology uses the high temperature aerobic fermentation process of NCS membrane compost machine to completely kill harmful eggs and germs, and the one-way permeability of the membrane material can block the spill of odor macromolecules such as ammonia and hydrogen sulfide, so as to achieve environmental protection and odorless treatment, and the operation cost is low, there is no need to turn the pile frequently and save labor. NCS membrane compost and ECS environmental protection compost box technology popularization and application, to achieve the purpose of promoting the typical mode. In the county's first NCS mode compost fermentation composting treatment conducted by Donglian Ruize Breeding professional Cooperative, after 20 days of high-temperature fermentation of livestock and poultry manure returned to the field, it can not only enrich the land, increase crop yield, but also reduce the pollution to the soil and environment, truly realize the transformation of waste into treasure, and promote the town's livestock and poultry breeding waste resource utilization process. At the same time, it will make positive contributions to promoting the green development of animal husbandry, the combined circular development of breeding and breeding, and the revitalization of rural areas.

After a series of transformations, Gaotai County has become an area with the main characteristics of the utilization of livestock and poultry manure resources and the production of organic fertilizers, and at the same time provides a reference and imitation case for agricultural production in other areas. We believe that with the support and cooperation of all localities, we will make more contributions to the green development of agricultural production. As an enterprise committed to promoting the green and environmental protection of environmental agriculture, we will continue to strengthen technical exchanges and cooperation with various places, and strive for the construction of a beautiful green ecological environment!
