实验研究

Wastewater containing titanium pigment was treated by microfiltration membrane, Nanometer titanium can be purified and concentrated by use of microfiltration. Operational conditions were optimized and the model was built. Finally, the amount of wash water was reduced. Based on the above research, the whole set equipment was designed, which can meet the needs in a titanium industry with a capability of 500 ton per year. Backflush and automatic control were used in the equipment, which has been steadily run two years, has been widely adopted in titanium industry. The technology has been widely adopted in titanium industry.In the recent years, whole set equipment of ceramic membrane was increasingly used in the recovery of desired production from fermentation broth in China. A new membrane process integrated with pretreatment of flocculation or coagulation was exploited to recover Inosine. ZrO2 ceramic membrane was used in the work, and the average permeation flux could reach 150L/m2.h under pH value of 3, transmembrane pressure 0.1MPa, CFV 3m/s, and temperature higher than 70C. The recovery ratio of inosine is higher than traditional recovery method, although inosine degraded under acidic and high temperature condition.

实验表明，ZrO_2膜处理肌苷发酵液的合适条件为pH=3、操作压力为0.1MPa、膜面流速3m／s、温度大于70度，此时可以获得平均渗透通量150L／m~2h，但由于酸性条件、高温下肌苷降解，导致肌苷收率有所降低，但仍高于传统肌苷提取方法得到的收率；为进一步提高肌苷得率，缩短提取工序，实验研究了絮凝剂预处理发酵液，解决碱性条件下由于蛋白析出导致膜污染加重的问题，研究表明采用CaCl_2絮凝并调节pH=11，可以获得平均渗透通量为180L／m~2h，肌苷得率大于95％；比较了三种肌苷提取工艺得到的产品质量，采用预处理与陶瓷南京工业大学博士学位论文膜分离结合的除杂工艺得到的粗昔质量与陶瓷膜分离、离子交换及活性炭吸附工艺生产的粗普质量相当，均优于传统的提取工艺；设计了每小时处理12一巧吨肌普发酵液的陶瓷膜成套装置，采用部分内循环的方式降低设备的能耗，简化了肌昔提取方式，提高了产品的收率和得率，由于减少离子交换和活性炭吸附，使得工厂废水排放量降低30一40%，降低酸、碱用量，有利于环境保护。

The supermolecule system building on the weak interactions between molecules has always been the focus on chemistry , bionomy , material science and informatics theoretically and experimentally . However , because the experiments fail to provide varied information in detail .

The research results show:(1) we combine time series method with the dispersed Markov Chains theory of stochastic process, and present a Markov Model based the time series analysis for predicting the precipitation for groundwater resources evaluation. Results show that the time series-Markov Model is efficient, and it has higher accuracy than that of the single model of time series;(2) started from the systematic point of view, we analyze the metabolic process of groundwater, establish the ultimate metabolic equation of groundwater for protecting the water resources, and discuss the value of reducing evaporation for making full use of the water resources;(3) Through a theoretical analysis of the results of the experiments, we draw a conclusion: the critical depth on evaporation of groundwater is in step with the height of the maximal capillary rise of media.

The results indicate that the heat transfer coefficient increase about fourteen percent between the bed and the wall and the one between the gas and horizontal tube increase about twenty two percent, it means pulsating promote heat transfer, Desulfurizing Characters Experimental Research on Pulsating Fluidized Bed With different initial SO_2 density, mean diametric of the calcium oxide and combustion temperature, the experimental results of desulfurization with pulsating or not indicate that the desulfurizing characters of the Rijke type self-exciting pulsating fluidized bed are the same with the conventional fluidized bed combustor, it is that the utilization ratio of the calcium oxide increasing with the initial SO_2 density, the desulfurizing combustion temperature has the best value and the utilization ratio of the calcium oxide reducing with the mean diametric of the calcium oxide.

脉动流化床脱硫特性实验研究对不同初始SO_2浓度、不同初始脱硫剂颗粒平均直径、不同燃烧区温度条件下脉动与非脉动状态下流化床内的脱硫实验研究表明，Rijke型自激式脉动流化床具有类似于常规流化床燃烧器的脱硫特性：固硫剂的CaO利用率随初始SO_2浓度的增加而增加，脱硫燃烧温度存在最佳值，以及CaO利用率随脱硫剂颗粒平均直径的增加而减小。
