| 中文摘要 |
| 本文通过室内及室外实际河流的监测,证明了水合肼的降解符合动力学一级反应。降解速度受水温、微生物、溶解氧、pH等因素影响,水温高,有微生物的存在,富氧及pH在6—8之间的条件下,降解速度快。温度对降解的影响符合KT=K20θ(T-20)公式。利用微机计算出K20与θ,结果pH为6时K20 0.02811/h,θ1.045,pH为8时K20 0.0211/h,θ1.036,计算与实测降解系数平均误差分别为1.17%和-10.7%。在所实验的河流中,水合肼的降解系数为0.3001/h平均误差为-5.87%。 |
| 英文摘要 |
| Labo ratory studies and monitoring practice in a river demonstrate that the degradation of hydrazine hydrate can be described by the first-order reaction dynamics. Its degradation rate was found to be dependent on water temperature, microorganism, concentration of dissolved oxygen, pH and other conditions. The effect of temperature on the degradation rate could be expressed with the formula: KT=K20. θ(T-20) Calculation with computer shows that when pH=6, then K20= 0.028 1/h and θ= 1.045, when pH= 8, then K20= 0.021 1/h, θ= 1.036. The degradation coefficient of hydrazine hydrate measured in the experiment carried out in the river was equal to 0.300 1/h. |
