Daxing Sludge Project adopts Germany's advanced mixing technology to change the microstructure, increase air permeability and deep inoculation. The ideal rapid composting can be achieved: 1. The material has air permeability, and the microorganism is evenly distributed in the material. 2. Rapid heating, rapid evaporation of water, dehydration at the same time make the material microporous increase, material specific surface area increase into a virtuous cycle. 3. The material should be static and gently supplied with wind to prevent the spillover of semi-reaction products.
