Effect of Water-soluble Organic Carbon Content of Initial Mixture on Composting Process for Tomato Stalk
摘要
Abstract
High-temperature aerobic composting technology is one of the important ways to cyclic reuse of organic waste.In China,the compost factories often take the ratio of total carbon to total nitrogen(C/N) of raw material to guide the compost production.But owing to the differences existing in the organic components of raw material,effective carbon source easily utilized by microorganisms should be selected to promote the composting process.This experiment took tomato stalk as main raw material,and wheat straw,corn starch and urea as attendant agents.The C/N ratio of initial mixed material was adjusted to 25,and moisture was controlled to 60%.The water-soluble organic carbon content(WOC)of initial mixture was regulated to 4%,8% and 12%,respectively.The paper studied the effect of WOC differences in initial mixed material on composting process.The results showed when WOC of initial mixed material was increased,the higher initial emission rate and higher accumulation amount of CO2could risebe,and the higher material loss rate would be.The shorter composting process was,better compost maturity might be,and easier compost would be started.When the WOC of initial mixed material was over 8%,the composting treatment of organic waste could be speeded up. While the differences between WOC of initial material would not affect the thorough decomposed and product nature.Therefore,increse WOC in the mixted initial material could be used as a method to speed up the compost procedure and a key index to guide compost production.关键词
