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.

含油污水处理工艺是一个复杂的处理过程，在处理过程中由于受到原水浊度、PH值、配水流量、原水温度和其他水质污染等因素的影响，处理难度相当大，现时的含油污水处理系统普遍存在处理后的水质不稳定和处理成本高等问题，国内外含油污水处理采用的方法有物理法、化学法、物理化学法和生物法等，每种处理方法都有自己的特点，结合电厂含油污水的情况，本文主要采用化学法，具体来说是采用絮凝沉淀的方法，通过向废水中投加混凝剂，使细小的悬浮颗粒和带电胶体微粒聚集成较大颗粒而沉淀，使其与水分离，使含油污水得到净化，使处理后的废水各项指标达到排放标准。

Many industrial multiversities and specialist colleges have been established, strengthening some incomplete subjects and establishing new specialties, e.g., automation , atomic energy , energy resources , oceanography , nuclear physics , computer science , polymer chemistry , polymer physics , radiochemistry , physical chemistry and biophysics . A project for creating 100 world class universities began in 1993, which has merged 708 schools of higher learning into 302 universities.

同时，中国的高校还开设了许多新的学科，比如自动控制，原子能，能源，海洋学，核物理，计算机科学，高分子化学，高能物理，放射能化学，物理化学和生物物理学。1993年，中国的高等教育主管部门开始了一项名为创造100所世界级的中国大学的工程，把原有的708所大学合并为现在的302所综合性大学。

By systemic researching and simulating experiment, the text gains such results as follows,1. On the base of sufficiency research on the oil-gas hydrocarbon systemic chemistry composing and the physical chemistry characters, we traverse the mechanism of the paraffin's deposition. Then we consider that paraffin deposition is a complex process ofphysical chemistry, which includes more than one single mechanism.2. Traversing and comparing the literature in detail on different factors that has effect on paraffin deposition, the available experimental methods on paraffin deposition, prevention of paraffin deposition, and removing of the deposited paraffin on the spot.3. Ameliorated the laser equipment of solid particle inspecting system and the corresponding test methods. Determine WCT of dead oil and live oil from KS101 well under different pressure with this system. The result implies that dead oil has opposite regulation on paraffin deposition temperature to live oil.4. A vapor-liquid-solid envelop is drawn by superposition regular vapor-liquid envelop and WCT curve thereby explained that the departure and quick raising of the curve in the low temperature zone is caused by the appearance of paraffin in solid phase.5. Estimation is made to determine the depth of paraffin deposition in the well.

通过系统的研究和实验模拟，本文取得了以下研究成果：(1)在充分调研油气烃类体系的化学组成及其物理化学特征的基础上，详细研究了石蜡沉降的机理，认为石蜡沉积是一个复杂的物理化学过程，是多种机理共同作用的结果；(2)深入调研并综合阐述了影响石蜡固相沉积的各种主要因素，对目前国内外常用的有机固相沉积实验研究方法和现场清防蜡措施也做出详尽的描述，并加以对比评价；(3)改进了油气藏开发重点实验室自行研制组装的高温高压下测定固相沉积的激光装置和测试方法，并用该套设备测定出柯深101井的井口脱气油样和凝析气平衡油样不同压力下的析蜡点，实验结果表明，脱气油和平衡油析蜡规律相反；(4)将常规气-液两相相图和析蜡曲线叠加得到了气—液—固三相相图，从而解释了气-液两相等液量线在低温区域偏离正常并快速上翘是由于体系有石蜡固相出现；(5)利用实验测试的析蜡温度预测析蜡位置，表明只有在距井口465m油管以上会有蜡析出。
