综述了淀粉和木质素两类天然高分子改性絮凝剂的研究进展，分别指出两类分散剂的研究方向，指出应充分利用这些天然高分子资源，从开发天然改性絮凝剂方面找到一条创新的道路。

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。

Tion sedimentation and air-water backflush filter tank, and the outlet water from the flocculation tank and sedimen-tation tank is collected, stored, adjusted, thickened and dewatered through a centrifuge.

长沙市第八水厂净水工艺采用桥板絮凝反应、平流沉淀和气水反冲滤池，并对絮凝池和沉淀池出水进行了收集、贮存、调节、浓缩、离心机脱水处理。

But do not have the flocculation ability nearly by testifying the amylum not having changed nature comparatively,that amylum obeys the butylene diacid Shan ester is fine flocculant of one kind of effect.

通过比较，证明未改性的淀粉几乎没有絮凝能力，而淀粉顺丁烯二酸单酯是一种效果良好的絮凝剂。

With amylum and amylum, along butylene diacid Shan ester, as flocculant, suspension liquid has carried out the flocculation experiment on kaolin.

以淀粉和淀粉顺丁烯二酸单酯作为絮凝剂对高岭土悬浮液进行了絮凝实验。

It is proposed that the appearance of a new kind of mud additive can not represent the formation of a new mud system . The main influence factors of flow resistance at drill bit nozzle are solid content , particle size distribution and hydrophilicity of solid . It is not suitable to use high shear viscosity of both Casson rheology model and determined to predict drilling efficiency .

全面、系统地论述了处理剂和泥浆体系的关系；聚合物的使用浓度应突破全絮凝点，实现低固相应以发挥聚合物的抑制作用为主，絮凝作用为辅；影响钻头水眼处流动阻力的主要因素是泥浆中的固相含量、粒度分布及固相的亲水性，用η_∞代表钻头水眼粘度是欠妥的；聚合物泥浆处理剂的发展主要是开发新的单体和研究新的复配物。

The lanolin in the flocculent deposit was been extracted by solvent of toluene. A high removal rate of COD can been also got by SPAM only, and raised with the concentration of SPAM. The removal rate of COD reached 94% when the concentration of SPAM was 300mg/L, but the floccules were difficult to deposit and filtrate.

絮凝沉淀物中的羊毛脂以溶剂甲苯提取，单独使用絮凝剂SPAM，COD的除去率也很高，且随SPAM的浓度增大而增大，当SPAM浓度达300mg/L时，COD除去率可达94%，但絮凝物沉降困难，也无法过滤。

At the same time, mass production of wooden lattice door mats and cushions, floc coconut, palm floc, sisal floc, water straw, paper rope, such as hand knitting material and packet edge sisal, straw carpets, car mats foot indoor carpet, cups mats, paper cloth, sisal wallpaper single fiber mesh such as woven fabrics, as well as for the export of all types of small packing rope type, line type of environmentally friendly products.

同时亦大量生产门口垫及木格座垫，椰絮，棕榈絮，剑麻絮，水草绳，纸绳等手工编结物和包边剑麻，草绳地毯，轿车室内垫脚毯，杯垫，纸布，剑麻单纤维墙纸网布等机织物以及各类专供出口的小包装绳类、线类环保产品。

When pH is 8.0, the flocculation rate can reach 91%. The experiment indicates that the evaluation system of kaoline is affected by PO(superscript 3- subscript 4) and Ca(superscript 2+) when the concentration of PO(superscript 3- subscript 4) is high in the substrate. As the real flocculation efficiency cannot be achieved, the evaluation system needs to be modified.

实验表明，培养基中PO(上标 3-下标 4)浓度较高时，现有的微生物絮凝剂高岭土评价体系会受到PO(上标 3-下标 4)与Ca(上标 2+)的影响，不能真实地表示微生物絮凝剂的絮凝效果，需要对现有评价体系进行修改。

And ,i found the tube hair seed fly only at very sunny day, not at rainy or cloudy day, maybe there is something relationship with the hollow structure.

而且我发现只有大晴天的时候，空中才飞杨絮，阴雨天和晚上都不飘杨絮，这可能就与杨絮毛的中空结构有关。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.
