An old man widower , unkempt hair , in bed , with head covered , sighing : an infirm dog , athos : aconite , resorted to by increasing doses of grains and scruples as a palliative of recrudescent neuralgia : the face in death of a septuagenarian suicide by poison 一个老鳏夫，头发蓬乱，戴着睡帽，躺在床上唉声叹气一只病狗，阿索斯作为发作性神经痛的镇痛剂，逐渐加量服用的附子一位七十岁上服毒自杀者的遗容。
And if we unite these them , we will get more advantages from them . this experiment made some prime lab research about the unition of the two ~ , processes . it contents : 1 ) jar test of optimized coagulation : to determine the quantity of drug 本试验对强化混凝和粒状活性炭吸附技术联用的处理工艺作了初步试验研究，试验内容包括： 1 )小试：通过杯罐试验来确定对于不同浊度的湘江源水的混凝最佳剂投加量。
While fractal dimensions of floes are 1 . 34 - 2 . 31 during different flocculating condition when the flocculating agents is polyaluminum chloride ( pac ) . moreover , under the best added quantity condition ( when the raw water is 170mg / l , the best added quantity of aluminum sulfate is 3 . 0mg / l and the best added quantity of pac is 2 . 0mg / l ) , no matter 若先投加cac12再投加pac ，混凝效果最好的水样的絮凝体的分形维数为1 . 48 ， cod去除率为93 % ，此时caci :的投加量为1
Through research of automatic dosing system , established by determining automatic dosage in the methods of transmittance pulsation , streaming potential and mathematical model , it can be concluded that the automatic dosing system brought forward in this paper can fulfill requirements of the technics . likely , this system can also be applied for dosing of other chemicals in water plants , chemical dosing of wastewater treatment plants and other similar places 通过对采用透光率脉动、流动电位、数学模型等方法确定混凝剂投加量建立的自动配投系统的研究表明本文提出的自动配投系统能满足工艺的要求：同样该系统也适用于给水处理厂其他药剂的投加，适用于污水处理厂及其他类似场合药剂的投加。
In practice , data acquisition , computing of chemical dosage , chemical mixture and chemical dosing can be integrated organically by utilizing modern automation technology , which enables the difficult manual chemical dosing system to become an integrate equipment and makes dosing automatically realized only if the required chemical dosage is input 在实践中通过应用现代自动化技术将数据的采集、药液投加量的计算、药液的配兑及投加有机地结合在一起：使人工操作比较复杂的药液配投系统变成一套完整的设备，只用输入需要的药液投加量就能自动实现投加。
The in - house system evaluation and field application showed that an excellent oil film for shielding temporary plugging could be formed near borehole wall and both plugging and recovering rates of permeability reached more than 90 % when the added amount of the broad spectrum oil film temporary plugging agent gpj reached 3 % ; skin factor decreased by 7 . 4 to 10 times and production increased by 1 . 82 to 2 . 96 times compared with conventional technology 结果表明，当广谱“油膜”暂堵剂gpj的加量达到3 %时，可在近井壁处形成很好的屏蔽暂堵“油膜”带，渗透率堵塞率和恢复率皆大于90 % ，与常规屏蔽暂堵技术相比，可使油层损害程度降低7 . 4 ~ 10倍，产量提高1 . 82 ~ 2 . 96倍，而且与油层渗透率和温度无关。
The main conclusion are as bwlow : 1 . for microflocilation / uf progress , ferric salts were better than aluminum salts ; the more dose of coagulant , the high removal rate of organic matter . however when dose increased to a certain level ( 6mg / l alo2 ) , fouling was higher instead 主要成果和结论如下: 1 .微絮凝-超滤工艺中,铁盐混凝剂比铝盐要好;随着混凝剂投加量的增加,有机物的去除率也随着增加,但当混凝剂投加量增加到一定量(以al2o3计为6mg / l )时,反而会加剧膜污染;投加pam (聚丙烯酰胺)对提高有机物去除率没有帮助,但可以缓解膜污染。
By designing some static flocculation experiments during different flocculating agent and different flocculating condition , the modal characteristic of floes are observed in experimented process and microscope photo of floes are shot . afterwards fractal dimensions of floes are calculated according to microscope photo of floes . the experimental result suggested that fractal dimensions of flocs are 1 . 31 - 2 . 38 during different flocculating condition when the flocculating agent is aluminum sulfate 当pac投加量为5 . omg / l并采用caci :为助凝剂时，若先投加pac再投加cacb ，混凝效果最好的水样的絮凝体的分形维数为2 . 43 ，化学需氧量去除率94 . 7 % ，此时的cacb投加量为1 . 5m留飞。
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。
According to researching several coagulant metering ways , we make a coagulant addition metering device which is based on fluid mechanics and chemistry . the device which frame work is simple can be used reliably , and we have obtained a patent for the device last year . the mathematical model is used to caculate the addition quantity of coagulant of different raw water quality , and the gravitational coagulant addition device ensure accurate addition quantity 本文通过对混凝剂计几种量方式的研究，尝试性的利用流体力学(伯努利方程)和化学(溶液浓度稀释)的原理，制作一个定量投加装置，对混凝剂加量进行计量，该装置结构简单，但是安全投靠，投资和运行费用低，具有提广价值，这种计量方式已经申请专利。
