本汙水排放標准一級AB標准是按照《城鎮汙水處理廠汙染物排放標准》GB18918-2002 內容參考，主要監測COD、氨氮、懸浮物、水中油、PH，並雲平台通過GPRS無線實時發布數據到顯示屏提示和報警，達到實時監測和預警目的。

根據城鎮汙水處理廠排入地表水域環境功能和保護目標，以及汙水處理廠的處理工藝，通過汙水監測系統将基本控制項目的常规污染物标准值分为一級標准、二級標准、三級標准。一級標准分为A标准和B 标准。一类重金属污染物和选择控制项目不分级。

1.2.1 一級標准的A 标准是城镇污水处理厂出水作为回用水的基本要求。当污水处理厂出水引入稀释能力较小的河湖作为城镇景观用水和一般回用水等用途时，执行一級標准的A 标准。

1.2.2 城镇污水处理厂出水排入国家和省确定的重点流域及湖泊、水库等封闭、半封闭水域时，执行一級標准的A标准，排入GB 3838地表水III类功能水域（划定的饮用水源保护区和游泳区除外）、GB 3097海水二类功能水域时，执行一級標准的B标准。

1.2.3 城镇污水处理厂出水排入GB 3838 地表水Ⅳ、Ⅴ类功能水域或GB 3097海水三、四类功能海域，执行二級標准。

1.2.4 非重点控制流域和非水源保护区的建制镇的污水处理厂，根据当地经济条件和水污染控制要求，采用一级强化处理工艺时，执行三級標准。但必须预留二级处理设施的位置，分期达到二級標准。

1.3 标准值

1.3.1 城镇污水处理厂水污染物排放基本控制項目，执行表1和表2的规定。

基本控制項目最高允許排放濃度（日均值）單位mg/L表1

采用KNF-400C汙水排放監測系統參考（測量指標：COD、氨氮、懸浮物、水中油、PH）

序號	基本控制項目		一級標准		二級標准	三級標准
序號	基本控制項目		A 标准	B 标准
1	化學需氧量（COD）		50	60	100	120^①
2	生化需氧量（BOD₅）		10	20	30	60^①
3	懸浮物（SS）		10	20	30	50
4	動植物油		1	3	5	20
5	石油類		1	3	5	15
6	陰離子表面活性劑		0.5	1	2	5
7	总氮（以N 计）		15	20	－	－
8	氨氮（以N 计）②		5（8）	8（15）	25（30）	－
9	總磷（以P 计）	2005年12月31日前建設的	1	1.5	3	5
9	總磷（以P 计）	2006年1月1日起建設的	0.5	1	3	5
10	色度（稀釋倍數）		30	30	40	50
11	pH		6－9
12	糞大腸菌群數（個/L）		10³	10⁴	10⁴	－

注：①下列情况下按去除率指标执行：当进水COD 大于350mg/L 时，去除率应大于60%； BOD大于160mg/L 时，去除率应大于50%。

②括号外数值为水温>120℃ 时的控制指标，括号内数值为水温≤120℃时的控制指标。

"The buildings are arranged to enclose an octagonal space, and consequently a visitor finds himself at the starting-point when he has made the rounds. The affair is in the hands of the gentlemen who controlled the Japanese department of the Philadelphia Exhibition in 1876, and many of the features of our Centennial have been reproduced. They have Agricultural Hall, Machinery Hall, Horticultural Hall, and Fine Arts Gallery, as at the Centennial; and then they have Eastern Hall and Western Hall, which the Quaker City did not have. They have restaurants and refreshment booths, and likewise stands for the sale of small articles, such as are most likely to tempt strangers. In many respects the exhibition is quite similar to an affair of the same kind in America; and with a few changes of costume, language, and articles displayed, it might pass for a state or county fair in Maine or Minnesota. "They don't wear any crinoline, such as the ladies do in America; and their clothes fit very tight around them when compared to what we see in New York—that is, I mean, they are tight in the skirts, though loose enough above the waist. They fasten them with strings and bands, and without hooks or buttons or pins. You remember the pocket pin-cushion you made for me? of course you do. Well, one day while we were taking tea in a Japanese tea-house, the attendants stood around looking at us, and examining our watch-chains and the buttons on our coats. I showed them that pin-cushion, and they passed it from one to the other, and wondered what it was; and so I took out a pin, and showed it was for carrying pins. Evidently they did not know what a pin was for, as they looked at it very curiously, and then made signs for me to show them its use. I did so by pinning up the wide sleeve of one of the black-eyed girls. She took the pin out a moment after to return it to me; and when I motioned that she might keep it, she smiled and said 'Arinyato,' which means 'Thank you,' as sweetly and earnestly as though I had given her a diamond ring. Then I gave each one of them a pin, and they all thanked me as though they really thought they had received something of value. Just think of it! half a dozen young women, not one of whom had ever seen a common dressing-pin! "But, Lieutenant, you don't know she loves him; there are signs, I admit; but proofs, no. She's lost color, and her curves are more slender, but, my goodness! a dozen things might account for that." "I would give all I possess in the world to clear it, Lawrence." The next morning at six I was out and about again. I had not been able to get any breakfast, for the people themselves had nothing. The Germans had called at all the hotels and shops requisitioning everything in stock to feed the thousands who had invaded Liège like so many locusts. The inhabitants practically starved during those days, and carefully saved up bits of bread already as hard as bricks. It was a good thing that the night before I had eaten something at the nunnery, for although at a shop I offered first one, and later on two francs for a piece of bread, I could not get any. Such is the mild and conciliatory mode of treatment at first adopted by Plato in dealing with the principal representative of the Sophists—Protagoras. In the Dialogue which bears his name the famous humanist is presented to us as a professor of popular unsystematised morality, proving by a variety of practical arguments and ingenious illustrations that virtue can be taught, and that the preservation of social order depends upon the possibility of teaching it; but unwilling to188 go along with the reasonings by which Socrates shows the applicability of rigorously scientific principles to conduct. Plato has here taken up one side of the Socratic ethics, and developed it into a complete and self-consistent theory. The doctrine inculcated is that form of utilitarianism to which Mr. Sidgwick has given the name of egoistic hedonism. We are brought to admit that virtue is one because the various virtues reduce themselves in the last analysis to prudence. It is assumed that happiness, in the sense of pleasure and the absence of pain, is the sole end of life. Duty is identified with interest. Morality is a calculus for computing quantities of pleasure and pain, and all virtuous action is a means for securing a maximum of the one together with a minimum of the other. Ethical science is constituted; it can be taught like mathematics; and so far the Sophists are right, but they have arrived at the truth by a purely empirical process; while Socrates, who professes to know nothing, by simply following the dialectic impulse strikes out a generalisation which at once confirms and explains their position; yet from self-sufficiency or prejudice they refuse to agree with him in taking their stand on its only logical foundation. today as the newspapers make out. “Guess I’d hide too!” “Well, this may not be the same one—we can easily find out.” "What do you want to know for?" asked the woman, at length. Accordingly, Charles could do nothing but maintain his position for the present in Scotland, and send off a messenger to France to announce his wonderful success, and to urge that now was the moment to hasten over troops and supplies, and secure the Crown and friendship of England for ever. He sent over Mr. Kelly to the French Court and to his father, and for a moment there was a lively disposition at Versailles to strike the blow. The king immediately despatched some supplies of money and arms, some of which were seized by English cruisers, and some of which arrived safely. There was also a talk of sending over Charles's brother, Henry, Duke of York, at the head of the Irish regiments and of others, and active preparations were made for the purpose at Dunkirk. But again this flash of enthusiasm died out, and Charles, three weeks after Kelly, sent over Sir James Stewart to aid him in his solicitations. But all was in vain. The French again seemed to weigh the peril of the expedition, and on their part complained that the Jacobites showed no zeal in England, without which the invasion would be madness. Thus the time went by, till the Dutch and English troops landed in England, and the opportunity was lost. "The best way's to settle him jest as he comes over the hill, half-a-mile away, with an ounce o' cold lead put where he lives. That'll take the pint offen his bayonet mighty certainly." million circuses had suddenly let out over there. The work went on, for Cadnan as well as for the masters. Days passed and he began to improve slightly: he received no further discipline, and he was beginning to settle into a routine. Only thoughts of Dara disturbed him—those, and the presence of Marvor, who was still apparently waiting to make good his incomprehensible threat. The wind puffed gently towards him, bringing him the song and the soft peach-smell of the gorse. Harry was a musician already of note among the farms; he had a beautiful voice, and there was very little he could not do with his fiddle, though of late this had been neglected for the claims of work and love. To-day he was singing an old song Reuben knew well—"The Song of Seth's House": "No, we must stick together." HoME 好白菜让猪霍霍完美性感身材颜值爆表华裔白嫩女神被纹身大洋屌肏抱起来日 ENTER NUMBET 0014tfqkl.com.cn
