Regeneration Reuse
In the first scenario a fraction of the total wastewater with lower contaminant concentrations produced by a water utilization system is regenerated for reuse with the remaining wastewater with higher contaminant concentrations treated for discharge. Because the required degree of treatment is different for regeneration of wastewater for reuse and end-of-pipe treatment of wastewater for discharge, two separate on-site treatment systems are envisaged. The whole water system can be broken down into three subsystems: water utilization system, wastewater regeneration system and wastewater treatment system, as shown in Figure 1.Wastewater produced by the water utilization system is split into two streams. Both streams undergo treatment to different degree in the wastewater regeneration system and wastewater treatment system. The regenerated water which meets the water quality requirements of the water utilization system is reused while the treated effluent which meets the discharge limit is disposed of.
再生再利用
在这第一种情况中,用水系统中产生出来的全部废水经过再生处理后,产生出一部分污染物含量较低的废水,和另一部分水污染物含量较高的废水,其中污染物含量较低的可以被再利用,而污染物含量较高的废水则经过处置后排出.由于再生处理过程中,对于废水再利用和废水最终排出的处理程度的不同,因此需要两个相互分立的现场处置系统.整个的水系统可以分成三个子系统：用水系统、废水再生系统、废水处置系统,如图1所示.用水系统产生出来的废水被分成两个水流,这两个水流分别流经废水再生系统和废水处置系统,接受不同程度的处理.满足用水系统要求的再生水可以被再利用,而满足排放标准的经过处置的水则被排出.
Figure 1…………………………….. 图1
The total cost of the whole water system includes the freshwater cost, regenerated water cost, and wastewater treatment and disposal cost:整个水系统的成本包括新水成本、再生水成本、废水处置和排放成本.
公式（1）
Where C is cost per unit time and the subscripts TW,F,R and D denote total water, freshwater, regenerated water and treated water for disposal, respectively. The cost of each type of water is given by the product of its flow rate and unit cost: 这里C是每单位时间的成本,下面的TW、F、R、D分别代表全部水量（TW）、新水（F）、再生水（R）、经过处置要排出的废水（D）.每种水的成本是它们的水流量和单位成本的乘积：
公式（2）
Where c is the unit cost of each type of water and F is the corresponding flow rate. The unit cost of freshwater CF can be taken as constant, but the unit cost of the regenerated water CR and the unit cost of the treated water for disposal CD are both changeable, depending on the selected treatment processes, quality and volume of wastewater for regeneration and treatment for disposal,
and effluent disposal fees. 这里的C是每种水单位成本,F是相应的水流量.新水的单位成本CF可以认为是常量,但再生水的单位成本CR和经过处置要排出的废水的单位成本CD则是变量,它们和处理方法、质量以及再生水和处置水的总量,还有排污费等有关.
A major parameter governing the total cost of an industrial wastewater reuse system is the post-regeneration contaminant concentration XPR. When xPR is small, the regenerated water is of high quality and it can be reused in many water-using activities, resulting in reduced freshwater demand and reduced volume of wastewater to be treated for discharge. Therefore, a small xPR will cause CR to increase due to a higher degree of treatment in the wastewater regeneration system and CF and CD to decrease due to reduced volumes of freshwater consumption and effluent for disposal. There might be an optimum xPR at which the total cost of the whole water system Ctw is minimized..影响工业废水再利用系统的一个主要参数是后期再生污染物xPR.当xPR较少的时候,再生水的质量较高,可以被再利用到各种生产活动中,可以减少新水的需求和使用,也可以降低废水排出的量.因此,较少的xPR会导致CR上升,因为这需要有较高处理能力的废水再生系统；较少的xPR也会导致CF和CD降低,因为需要较少的新水以及产生出来的废水也较少.因此,有可能存在一个最优的xPR,这个时候整个水系统的成本Ctw最小.
问题补充：Treatment Reuse 处理再利用
In the second scenario the total wastewater produced by a water utilization system is treated in a single on-site treatment system to meet the water quality requirement of the utilization system as well as the discharge limit, as shown in Figure 2. The wastewater treatment system treats the wastewater produced by the water utilization system to two different levels , one at a relatively high level for reuse in the water utilization system and the other at a level that meets the discharge limit for disposal.
The cost equations for this case are similar to those described above for the case of wastewater regeneration reuse: 在这第二种情况中,用水系统中产生出来的全部废水经由一个现场处理系统的处理,产生出满足用水系统要求的、可以再利用的水,以及满足排放标准的排出废水,如图2.这种废水处理系统将用水系统中产生出来的废水处理到两个程度：一个是相对较高的程度,可以满足用水系统的用水标准；另一个相对较低的程度,是满足排放标准的程度.这种情况的成本计算公式和上面描述的废水“再生再利用”的情况中的公式是类似的.

问题的意思是,能被30整除的数,而且小于等于360,这些数有多少可以被12整除,比例是多少?
可以被30整除的,30,60,90,120,150,180,210,240,270,300,330,360
其中可以被12整除的,60,120,180,240,300,360
比例是6/12,也就是50%
简便的算法：360/30,也就是说360内,12个整数被30整除
30和12的公倍数,60,360内,6个整数被60整除
6/12=0.5

“零头按比例分配”是指：在计算任何带美分的金额或计算装卸时间（受载期）的天数时,零头部分应按照相应的单位四舍五入计算.
上述是我的理解,但是我的表述可能不严谨.就是比如 0.6美分是1美分,1天半的受载期,算两天,反之,0.4美分算0美分,没有到半天的受载期,则不计入受载期的时间内.
给你以1句拆分的话：
a) A fraction of a cent in any calculation shall be rounded up to the nearest cent if such fraction is one half of a cent or more,and shall be rounded down when otherwise.
a)货币单位 “分”以下的单位,按四舍五入计算.
至于受载期lay time,单位应该是天,但是具体如何象上面这句话表述,我不确定.
希望能给你一些帮助.
