In this embodiment, it is desirable

In this embodiment, it is desirable to enforce the anaerobicity in the anaerobic tank and promote the release of phosphorus. Consequently, it is desirable to introduce the sludge which has been solubilized in the solubilizing means into the anaerobic tank after it has been subjected to a fermentation treatment.
In the immediately aforementioned apparatus for the biological removal of phosphorus, the aforementioned solubilized sludge returning means may supply only some of the sludge which has been solubilized in the aforementioned solubilizing means to the aforementioned fermentation tank, and there may be provided a means by which the remainder sludge which has been solubilized in said solubilizing means is supplied to the aforementioned second solid/liquid separating means.
With the aforementioned apparatus for the biological removal of phosphorus, the phosphorus dissolved out from the sludge by solubilization can be transferred into the separated liquid in the second solid/liquid separating means, and so the phosphorus removal efficiency is increased.
In any of the aforementioned apparati for the biological removal of phosphorus, there may be provided a means which supplies some of the sludge which has been subjected to a fermentation treatment in the aforementioned fermentation tank to the aforementioned second solid/liquid separating means.

在此体现，它是需要执行 anaerobicity 在厌氧池和促进磷的释放。因此，它值得介绍已被溶解中的增溶的手段进入厌氧池受到发酵处理后的污泥。在生物除磷立即上述装置，返回意味着上述溶解的污泥可供只有一些污泥已被溶解在上述的增溶手段对上述发酵罐中，并那里可能提供的剩余污泥，已被溶解在说增溶手段提供给上述二固液分离手段的一种手段。与上述仪生物除磷，磷溶出从污泥的增溶作用可以转入第二固液分离手段，分离液体和那么磷的去除效果也会增多。在任何的生物除磷的上述仪器中，那里可能提供提供一些污泥它遭受到在上述第二个固液分离手段对上述发酵罐的发酵处理的一种手段。

在该实施例中，它是理想的执行anaerobicity在厌氧池和促进磷的释放。因此，需要引入污泥已溶解在溶手段进入厌氧池后已进行了发酵处理。对生物除磷的
立即上述装置，上述溶解污泥回流装置可以只提供部分污泥已溶解在上述溶解意味着上述发酵罐，并有可能提供一种手段，剩余污泥已溶解在说增溶方法提供上述第二固/液分离的手段。
对生物除磷的上述装置，磷溶出污泥的溶解可以转移到分离液第二固/液分离装置，使磷的去除效率提高。对生物除磷在上述装置
，可以提供一种装置，该装置提供上述发酵罐中所经过发酵处理的污泥，以上述二次固液分离装置。
