Abstract
Employing S-15 - bio-toilet as the testing device and pulverized bean stalk particles as the conditioner, an experimental study is made on the aerobic reduction and changes of nutrient content of human feces. The index changes of PH value, organic matter, total nitrogen (TN), total phosphorus (TP) and total potassium (TK) etc. are measured. The results show that using bean stalks as the bio-toilet conditioner has a good treatment effect. The average decomposition rate of the dry weight of the mixture per week is 37.49% ,and the cumulative decomposition rate reaches 95.23%. In the resulting products, the PH value is 7.2, the total amount of organic matter is 71.02% and the content of TN, TP and TK is 3.72%, 1.53% and 4.71%, respectively. The resulting products can be recycled as an efficient organic fertilizer.
