A Study On The Reduction Of Kitchen Garbage By Sawdust And Corn Stalks As Reaction Matrix

With the development of society. component characteristic of city garbage take place variety,the kitchen garbage take part 50% in city garbage. There are kinds of methods to deal with it, exploiture the garbage processor is the primary means of method right now.The equip we used in this research is s-15 bio-toilet. The main structure is a rectangular box, filling in reaction matrix. The experimental Principle is mainly by running with 40w/h power, with aerobic and anaerobic microorganisms exothermic fermentation, convert the excrement into water, carbon dioxide and with little residue.The garbage we used mainly from Beiyuan restaurant in Northeast Normal University. Use sawdust, corn stalks as research objects, kitchen garbage and matrix with a ratio of 8:1. Experiments were conducted 24d, 18d respectively. The research opened an exhibition to carry on the measurement of parameter, temperature, pH, humidity, Biological degradation, total P.The experiment results show that use sawdust, the garbage reduction rate is 55%, Temperature change from 50℃-56℃, Humidity from 60%-70%, pH from 5.0-7.7, Biological degradation is 25.4%, total P is 4.84%.Use corn stalks as reaction matrix, garbage reduction rate is48.3%, Temperature change from 50℃-55℃.Humidity from62%-63%, pH from5.5-6.6, Biological degradation is 27.3%, total P is 4.04%.At last, we found that for the sawdust as matrix to degradate the garbage the reductions (55%) better than for the corn stalks as matrix (48.3%). Because of making less use of land, spare power, easy to manage and save water, provide another method to deal with kitchen garbage.
