T/WEA 028-2026 Specification for digital control technology of high-value utilization of manure in large-scale livestock farms

Scope

The resource utilization of manure from large-scale livestock farms is a key link in pollution prevention and control of livestock and poultry breeding and the development of green and low-carbon agriculture. With the expansion of farming scale and the increase in manure production, the collection, storage, treatment, and land application of manure face challenges such as large load fluctuations, complex working conditions, prominent risks of odor and leakage, difficulties in managing utilization destinations and accounting records, and high regulatory compliance requirements. Traditional management methods rely heavily on manual record-keeping and decentralized equipment control, making it difficult to achieve real-time monitoring, process control, and closed-loop traceability of the entire process of manure generation, treatment, transportation, and utilization. This results in unstable resource utilization efficiency, inconsistent product quality, and difficulty in timely identifying and addressing environmental risks, hindering the large-scale promotion of high-value utilization models for manure. High-value utilization of manure refers to transforming manure into products or services with stable quality and measurable value through technologies such as solid-liquid separation, anaerobic fermentation, composting, utilization of digestate and digestion liquid, nutrient recovery, preparation of organic fertilizers/organic-inorganic compound fertilizers, and substrate and energy utilization, under the premise of meeting pollution prevention and biosafety requirements. It places higher demands on process parameter control, raw material characteristics identification, nutrient and water dynamic management, pathogen and impurity risk control, and product quality evaluation. At the same time, it requires precise management of output, utilization destinations, application quantities, application plots, and timing to achieve nutrient balance, emission reduction and effi
