Solving the problem of city life garbage disposal in small cities is an urgent issue. The minimum reasonable treatment capacity of a waste incineration power generation is generally 500 to 600 tons per day

but the amount of municipal waste in a small city is about 150 to 300 tons per day. The samll city can not independently build waste incineration power generation project. To solve this problem

it is recommend to increase modest amount of biomass straw to meet minimum reasonable size in the peripheral area of the project. The problem that city garbage has properties of low calorific value

high ash

high moisture and insufficient production could be solved. And the problem of secondary pollution caused by burning straws around small cities in spring and autumn could be solved. Therefore the model "garbage + straw" mixture could be used as a new way of "harmless

minimization

resource-oriented" environmental protection and biomass renewable energy utilization.
