We are the first class engineering company that apply the ims technology to the pure water industrial waste water reclamation projects in electric led power pcb steel petrochemical industry successfully . we are inviting risk investment to this technology and carry out in bot mode 应用全膜法进行工业废水、中水的深度处理和回用技术成功应用于石化、电子、 pcb板、钢铁、印染等行业，应用bot运作模式能带来巨大经济和环境效益。
Based on 28 months pilot test data , some treatment units ’ ( including pre - treatment , enhanced coagulation , enhanced flotation , enhanced filtration , advanced treatment and sequeutial chlorinatio disinfection ) efficiency is evaluated to seek optimal running parameters . the results show that pre - treatment technology could reduce coagulation dosing rate , enhance the traditional treatment ( coagulation + daf + filtration ) effluent quality , accelerate destab . ilization of organic matter , increase water quality guarantee ratio of traditional treatment 在为期28个月的中试试验研究中,通过对预处理技术、强化混凝技术、强化气浮技术、强化过滤技术、深度处理技术、安全消毒技术等单元工艺技术的处理效能进行了系统评价,确定了各单元工艺的最佳运行参数。
For settling the contradictions among gradually polluted yellow river water , falling behind technology of water factory and desired improvement of water quality , for renewing baotou water factories and rebuilding new water factory , this experiment research provides the best process choice and design basis , which can be used as an example by person of the same profession , therefore creates fine condition for carrying out deeply water treatment and ensuring the safety of drinking water , and which has broad social returns and market applying prospect 本文的试验研究为解决黄河水源日渐污染、水厂工艺落后与出水水质不断提高之间的矛盾、为包头市各水厂的更新改造和今后建新水厂提供了最佳的工艺选择和设计依据，并可为广大同行所借鉴，从而为实施水质深度处理、保证饮用水安全提供了行之有效的途径，具有广泛的社会效益和广阔的市场应用前景。
The purpose of this study is to improve the efficiency of algae removal by enhancing coagulation and filtration and analyze the efficiency of all kinds algae removal in the every phase of the processing and remove remained algae from disposed water . test of enhanced coagulation with polysilicon ferric sulfate , polysilicon ferric chloride , ferric sulfate , polyalumoferrochloride , polysilicon aluminum sulfate , polyaluminium chloride and polysilicon aluminum chloride upon algae removal are described 本文主要是为强化常规水厂的“混凝?过滤”工艺的除藻效率而进行的实验室研究，包括对湖泊水中的藻类生物进行强化混凝和过滤，分析了各种藻在“混凝?过滤”工艺各阶段的去除率，并对水中的残存藻进行了深度处理的研究。
Under the permitted conditions , the all - scale plant was made to pre - ozonation . the results showed : ( l ) the optimal advanced purification drinking water process should be " regular treatment + ozonation + biological activated carbon " . though pre - ozonation had no effects on ammonia nitrogen in the water of micro - pollution water source , instead the turbidity of pre - oxidation finished water was raised , it had effects on killing bacteria and removing algae , and controlling the growth of micro - organism 得出如下结论： ( 1 )最优化的深度处理饮用水的工艺应该是“常规处理+臭氧化+生物活性炭” ，如果投加预臭氧，对微污染水源水中的氨氮没有效果，反而引起预氧化出水的浊度升高，但是对灭菌除藻，控制微生物的生长有一定的作用。
Water pollution was becoming intensified , while with the improvement of human ' s living standard , more attention was increasingly paid to the sanitation and safety of drinking water . so adopting advanced drinking water purification to obtain high quality water was necessary . by changing the different combination of drinking water ' s regular treatment process , ozonation , activated carbon and biological activated carbon , the paper chose the optimal treatment process , also the parameters of the process were analyzed through experiments , then the economic , reasonable process parameters were determined 水污染不断在加剧，而随着人们生活水平的提高，饮用水的卫生和安全越来越被关注，因此有必要采用先进的饮用水深度处理技术来获得优质饮用水，本文通过改变饮用水常规处理工艺、臭氧化、活性炭与生物活性炭的不同组合的中试试验研究，选择出了最佳处理工艺，又对最佳处理工艺的各个参数进行试验分析，确定出经济合理的工艺参数，在现有的条件下，对预臭氧化进行了生产试验。
