摘要:
污泥厌氧消化、干化焚烧、热解气化焚烧等污泥处理工艺和技术，是进入高质量发展阶段以及践行“双碳”政策的重要技术选择。郑州新区污水处理厂一期污泥采用厌氧消化干化工艺，二期污泥采用热解气化焚烧工艺，并在一、二期基础上实现污泥厌氧消化和污泥热解气化焚烧耦合，最终实现污泥处置的减量化、无害化、稳定化、资源化。该污水处理厂1 000 t/d污泥消化和100 t/d污泥气化焚烧实际运行数据表明，污泥厌氧消化和污泥焚烧不是必须二选一，相反，从全过程能量平衡角度，污泥厌氧消化和污泥热解气化焚烧耦合技术是实现能量利用最大化的优选工艺组合。
Abstract:
Sludge treatment processes and technologies such as anaerobic digestion, drying and incineration, and pyrolysis gasification and incineration must be considered at the stage of high?quality development and implementing “carbon emission reduction and carbon neutrality” policy. Phase Ⅰ sludge of Zhengzhou New Area wastewater treatment plant (WWTP) adopts sludge anaerobic digestion and drying process, and phase Ⅱ sludge adopts pyrolysis gasification and incineration process. On the basis of phase Ⅰ and phase Ⅱ, the coupling of sludge anaerobic digestion, pyrolysis gasification and incineration is realized, and finally the reduction, harmlessness, stabilization and resource utilization are realized. The actual operation data of 1 000 t/d sludge anaerobic digestion and 100 t/d sludge gasification and incineration project of Zhengzhou New Area WWTP show that sludge anaerobic digestion and sludge incineration are not either one or the other. On the contrary, from the perspective of energy balance in the whole process, the coupling technology of sludge anaerobic digestion and sludge pyrolysis gasification is the optimal process combination to maximize energy utilization.
