As a effective pretreatment of excess sludge treatment, thermochemical hydrolysis method was not only good at cells disintegration, but also enhancing the treatment results of subsequent process. This experiment improving the traditional thermochemical method by separated the thermal process and the alkaline process. Examined SCOD value, SOCD remove rate of sludge and biogas production of anaerobic...
Liposoluable tea polyphenols(LTP) were synthesized by chemically modifying tea polyphenols(TP) with stearyl chloride. FTIR analysis indicated that carbonyl and long carbon chain were introduced into the tea polyphenols. The optimal process parameters were given as follows: n(TP)/n(stearyl chloride)/n(Na2CO2) = 1/1.5/1.5, and the experimental conditions were controlled at 80°C for 4 h. The applications...
The germinating capacity of wheat was investigated in the presence of butyhted hydroxy toluene (BHT) with ultraviolet (UV) radiation. The influence of UV and BHT on the growth of wheat was evaluated by means of variability of chromosome of germinating root tip cell mitosis and activity of superoxide distamuse (SOD) of malt. The results show that the germinating capacity of wheat reaches 87% when the...
