Scope

Scope: This document specifies the terms and definitions, site selection and requirements, raw material selection, vegetable waste treatment, compounding, and application aspects of the resource utilization of vegetable waste. This document is applicable to the resource utilization of vegetable waste; Main technical content: 6. Vegetable waste treatment 6.1 Raw material fermentation 6.1.1 Raw material pretreatment Select a clear and windless day to clean the fermentation site and lay a plastic tarpaulin on its bottom. Use a wet material crusher to crush the vegetable waste, with the diameter of the waste stems controlled between 1.00 cm and 5.00 cm. Use a dry material crusher to crush the crop straws, with the diameter of the stems controlled between 0.50 cm and 1.00 cm. 6.1.2 Formulation Evenly add 400.00 kg to 500.00 kg of crop straws, 100.00 kg to 150.00 kg of sheep manure, 1.00 kg to 1.50 kg of urea, and 1.00 kg to 1.50 kg of microbial fermentation agents to 1,000.00 kg of vegetable waste raw materials. Then mix them thoroughly, adjust the moisture content of the fermentation pile to 60% to 65%, and ensure that the technical indicators of the microbial fermentation agents comply with GB 20287. 6.1.3 Pile construction Stack the mixed vegetable waste into a terraced pile 2.00 m to 4.00 m wide, 1.00 m to 1.50 m high, and 10.00 m to 50.00 m long. Cover the surface of the pile with a plastic tarpaulin, secure it against the wind on all sides, and leave 20 ventilation holes with a diameter of 1 cm per square meter on the sides.
