我国每年产生大量的固体废弃物，包括农作物秸秆、畜禽粪污和餐厨垃圾等。厌氧发酵技术在处理固体废弃物的同时还可以得到气体能源。与常见的甲烷发酵相比，两阶段厌氧发酵产氢产甲烷可将固体废弃物污染物转化为更为清洁的氢气与甲烷的混合气，同时还可提升发酵效率以及有机负荷的承受能力。my country produces a large amount of solid waste every year, including crop straw, livestock and poultry manure, and kitchen waste.

In addition, the reactor used is a conventional fully mixed reactor, and the concentration of microorganisms in the reactor is low, resulting in low reaction efficiency and long reaction cycle. Mass transfer in the fermentation reactor with high concentration of solid waste is also a problem currently faced.
