| 3. | For optimal disinfection efficacy , human safety and health of the fish , the system should be installed with an ozone contact tank where ozonation is done inside the tank with sufficient contact time 臭氧消毒系统应设有臭氧接触缸,以容许臭氧有充分时间在接触缸内溶于水中,这样的消毒系统才能发挥最大效用,同时亦不会影响人和鱼类的健康。 |
| 4. | 5 for optimal disinfection efficacy , human safety and health of the fish , the system should be installed with an ozone contact tank where ozonation is done inside the tank with sufficient contact time 5臭氧消毒系统应设有臭氧接触缸,以容许臭氧有充分时间在接触缸内溶于水中,这样的消毒系统才能发挥最大效用,同时亦不会影响人和鱼类的健康。 |
| 5. | An experiment was conducted to examine ozone disinfection of effluents from a municipal secondary sewage treatment plant . affecting factors such as ph , contact time and ozone dose are studied 摘要介绍了臭氧在水中的化学特性和消毒的基本原理,通过试验研究了臭氧在城市污水深度处理消毒中的反应过程,认为臭氧在城市污水处理二级出水中的消毒是可行的。 |
| 6. | With the prolong of contact time , the increment scope of ttms and halogen acetic acid will decrease . d ) comparing to chlorination , chloroamine disinfection is a better way in reducing the mutations of the objects in drinking water D )氯胺消毒方式在减小饮用水的致突变性即降低饮用水的毒副方面明显优于氯消毒,对总aoc的生成具有较好的抑制作用,水体生物稳定性优于氯消毒方式。 |
| 7. | Effect of pre - oxidation on alum coagulation evaluated through the change of turbidity 、 toc and uv254 . the emphasis on some impact factors such as the kind or variety of oxidant and oxidant contact time were studied , with discussing the influence of ph and solution temperature 试验中先投加氧化剂,再投加混凝剂,充分沉淀后,检测出水浊度、 toc和uv254 ,通过这些指标变化来评价预氧化对混凝效果的影响。 |
| 8. | The algae removing rate of four algaecides increased with dose increasing , and the sequence of four algaecides " removing rate on algae from high to low were potassium permanganate , sodium hypochlorite or copper sulfate and hydrogen peroxide . the suitable contact time of four algaecides was also given . the paper compared with the rate of algae removal by any one of three algaecides for two source water 结果表明,实验期间,引黄水中藻类绝大多数为硅藻,优势藻属为硅藻门的直链藻属,占藻类总数的78 94 ;四种杀藻剂的藻类去除率随杀藻剂投加量的增加而提高,实验条件下,四种杀藻剂的藻类去除率由大到小依次为:高锰酸钾次氯酸钠或硫酸铜过氧化氢。 |
| 9. | Analyzing companies with high - level customer contact , as the longest contact time and easy interaction in the delivery process , the paper will point out the advantages and disadvantages of obtaining customers " satisfaction , and design a fuzzy mode in evaluating customer satisfaction . after researching a restaurant in detail as a " real world " example , this paper will explore the entire process of implementing the strategy of customer satisfaction 通过分析高接触型服务企业与顾客接触时间长、顾客较容易参与和评价服务过程等特点,指出了高接触型服务企业在实施顾客满意战略过程中的优、劣条件,并同时给出了此类企业进行顾客满意度模糊测评的模型。 |
| 10. | Three models are proposed as follows by applying the model of " mixed flow " : the stress of increasing fluid on fouling , collision between solid particles and fouling , and solid particles movement velocity ; the effects of operating parameters , properties of particles , and the volume fraction of particles on stress in solid - liquid two phase flow , collision stress between solid particles and fouling , maximal contacting area between solid particles and fouling and maximal contacting time between solid particles and fouling are investigated systematically by calculating and theoretical analysis 利用“混流”模型,建立了两相流体的剪应力模型、固体颗粒与垢层的碰撞模型和固体颗粒的运动速度模型;通过计算和理论分析,系统地考察了操作参数、颗粒物性、颗粒体积分率等对固液两相流剪应力、颗粒对垢层的碰撞力、颗粒与垢层的最大接触时间和最大接触面积的影响。 |
