[英翻中]請英文高手幫幫我忙

A combination of primary and secondary treatment (Figure 22-16) removed 95-97% of the suspended solids and oxygen-demanding organic wastes, 70% of most toxic metal compounds and non-persistent synthetic organic chemicals, 70% of the phosphorus (mostly as phosphates), 50% of the nitrogen (mostly as nitrates), and 5% of dissolved salts. But this process removes only a tiny fraction of long-lived radioactive isotopes and persistent organic substances such as some pesticides.

不要翻譯軟體喔~因為就是翻不出來覺得怪怪的才請高手幫忙

    化合主要和次要處理(圖22-16)來分離95-97%的懸浮固體和高需氧有機消耗,70%的最大量有毒金屬化合物和無持久性合成有機化學製品,

    70%的磷(主要是磷酸鹽),50%的氮(主要是硝酸鹽),和5%的分解鹽。

    但是此過程僅能去掉長時間放射性同位素的微小碎片和持久性有機物質,例如一些殺蟲劑。
