Treatment Status of Kitchen Waste and its Enzymolysis Properties

Abstract

Three dining rooms located in east and south campus of Zhengzhou Institute of Aeronautical Industry Management were selected as the sampling points for the research. The kitchen waste disposal in Zhengzhou city was in a disorder state, and there was great space for the policy and social demand of the concentrating recycling of kitchen waste. The kitchen waste contained 19.52% of crude protein, 4.08% of crude fiber, 21.19% of fat, and 29.67% of total starch. After enzymolysis of the organic matter in the kitchen waste, the crude protein was degraded 61.17%, the crude fiber was degraded 50.90%, the crude fat was degraded 27.42%, the total starch was degraded 71.22%. The next stage of important research problems for the kitchen waste treatment were desalination and degrease technology, secondary pollution control technology, and the technology of reducing the inputs of auxiliary material.
