In the MAP reaction column 2, an al

In the MAP reaction column 2, an alkali such as NaOH is introduced in such a way as to set the preferred pH conditions of from pH 8 to 10, and most desirably of from pH 8 to 9, for MAP, along with, in those cases where there is insufficient magnesium to precipitate MAP, the addition of a magnesium compound such as M g C l2 or M g ( 0 H ) 2, for example, (this should contain a magnesium compound and may be sea water), and the phosphorus and ammonia in the liquid react with the magnesium to form MAP which forms a precipitate, and the phosphorus in the liquid is removed in this way. In particular, the phosphorus in the solubilized sludge is in the form of orthophosphoric acid which is convenient for the formation of MAP as a result of the biological treatment, and the MAP formation reaction efficiency in the MAP reaction column 2 is high and so the removal of phosphorus is carried out efficiently.
The liquid which flows out of the MAP reaction column 2 is generally a liquid which has a phosphorus concentration of some 10 mg/1 and this discharged liquid is then introduced into the denitrification tank 3. In the denitrification tank 3, the B O D in the waste-w ater is utilized and the N 0 3 and N 0 2 in the nitrification cycle liquid provide for nitrogen removal.

地图反应列 2，碱，如氢氧化钠中介绍了一种设置首选的 pH 条件的从 ph 值为 8 到 10，和最刻意的从 ph 值 8 到 9，地图，相处，在这些情况下那里有不足镁沉淀地图，另外的镁化合物如 M g C l2 或 M g (0 H) 2例如，(这应该包含镁化合物，可能是海水)，与镁形成地图形成沉淀反应的磷和氨液中的和液中的磷去除以这种方式。尤其是，溶解污泥中的磷是磷酸对生物治疗，形成图方便的形式和地图反应列 2 中的地图形成反应效率较高，所以除磷有效地进行。液体的流出地图反应柱 2 通常是液体，有一些 10 毫克磷浓度/1 和此排出的液体然后引入反硝化罐 3。在反硝化罐 3，利用中浪费 w 亚特的 B O D 和 N 0 3 和 N 0 2 在循环液体中硝化脱氮为提供。

在地图的反应柱2，碱如NaOH中引入了一个从pH值8至10套首选的pH条件下，最理想的pH从8到9，地图，以及，在这些情况下，没有足够的镁沉淀的地图，一个镁化合物如M G C语言或m g加入2（0小时），例如，（这应该包含一个镁化合物，可能是海水），磷和氨的液体反应与镁形成地图，形成沉淀，和磷在液体中被删除，以这种方式。特别地，在溶解污泥磷以磷酸便于地图的形成是由于生物治疗的形式，和地图生成反应效率的地图反应柱2那么高，磷的去除是
高效进行。流动的图反应柱2的液体一般是一个液体，其中有一个磷浓度约10毫克/ 1和这个排出的液体，然后引入到反硝化池3。在反硝化池3，B O D在waste-w水是用来和N 3和N 0 0 2在硝化循环液为氮的去除。
