The oil sewage disposed process is a complex disposal technique. The disposal process is more difficult for the change of PH Flux temperature of raw water and the other polluted quality. At present the disposed water by the system of oil of sewage is unstable and high cost. Now the method for the oil of sewage have physics chemistry physical chemistry and biology etc. In the every disposed method has its own specially, Basis of the oil sewage condition of power plant. The text use chemic method. Another word is method of Flocculation-deposition. Injecting Dosage into sewage. Making small suspends grain and the electrophorus colloid gather into bigger colloid and deposit. Separated it from water and purify the oil sewage. Make disposed oil water up to grade.

The first part discusses about the effects of the five factors:temperature,relative air moisture,rate of frass sifting,density of larvae,fodder water percentage to growth speed and survival rate of older mealworm (Tenebrio molitor L.) larvae through rotational composite design of quadratic regression. Two models were established to describe the effects of the five factors. The models showed that percentage of fodder water is the major factor that has effect on the growing speed of T. molitor larvae,and fodder water is the major factor on death rate. The models also show that temperature on growth speed,temperature and fodder have important effects on death rate,and the significant test showed they have significant difference on 1% or 5% level. From the two models,by frequency analysis,we can get the optimizing rearing condition,in which the mealworm larvae overweight 10% per day,temperature is 25-26 ,frass sifting rate is once 2-4 days,density of larvae is 0.61-0.79 g/cm2,fodder water is 33.27%-39.71%. And the rearing condition,in which total death rate of T.
第一部分:采用五因素二次正交旋转组合设计,以黄粉虫幼虫饲养过程中饲养温度(X_1)相对湿度(X_2)、虫粪筛除频率(X_3)、饲养密度(X_4)以及饲料含水量(X_5)五因素为参试因素,考查它们对黄粉虫高龄幼虫的生长及存活的影响,建立了以黄粉虫幼虫增重率及死亡率为目标函数的回归模型,并进行了简化: Y_增=127.5079+18.6559x_5+2.7894x_3x_4-2.3854x_3x_5-3.0594x_1~2+1.8241x_3~2-3.8559x_5~2 Y_死=1.7459+0.4108x_1+0.0975x_2+0.9025x_4+0.3442x_5+0.0834x_1~2+0.3060x_4~2-0.2623x_5~2 分析结果表明:影响黄粉虫幼虫生长后期增重及死亡的主要因素分别为饲料含水量和饲养密度;饲料含水量和温度对黄粉虫增重有着重要的影响,饲养密度、温度、饲料含水量对黄粉虫的死亡有着重要的影响,其影响均达1%或5%显著水平;黄粉虫幼虫后期日增重率大于10%的饲养条件为:温度26~27℃、筛粪频率2~4天/次、饲养密度0.61~0.79g/cm~2、饲料含水量33.27~39.71%。

Thermal conductivity is measured by the transient hot-wire method, which shows that the thermal conductivity increases with the increase of nanofluid particle volume fraction and temperature. The thermal conductivity of 0.3vol% SiO2-water nanofluid increases by 11.5% at 25℃, while it increases by 46.5% at 50℃ when compared with water at the same temperatures.
