摘要

PPROBLEM TO BE SOLVED: To provide a water path and a member for removing nitrogen/phosphorus contained in waste water which permits concurrent cleaning (removal) of nitrogen/phosphorus in the water path and a closed water region, allows phosphorus adsorption ability of a phosphorus adsorbent to continue, facilitates the recovery of the phosphorus adsorbent and prevents the clogging of the water path. PSOLUTION: The water path is formed by fixing the phosphorus adsorbent capable of producing apatite hydroxide through the contact with phosphorus in waste water to a water path body via a nitrogen cleaning agent liquefied by heating. The phosphorus adsorbent is granular material which comprises coal ash, volcanic ash or molten steel slag each containing calcium in plenty, waste molten slag or artificial zeolite originating from coal ash and produces the insoluble apatite hydroxide. The nitrogen cleaning agent is an organic carbonaceous water cleaning agent which has a melting point higher than the water temperature of waste water to be treated, is decomposed by microorganisms to produce hydrogen and an organic acid or an biologically utilizable organic substance and promote denitrification.

要解决的问题：提供一种水路径和一种用于去除废水中所含氮/磷的构件，以允许同时清洁（去除）水路径和封闭水域中的氮/磷，并具有吸附磷的能力磷吸附剂的连续吸收，有利于磷吸附剂的回收并防止水路堵塞。

解决方案：通过将能与废水中的磷接触而生成磷灰石的磷吸附剂经加热液化的氮气净化剂固定在水通道体中，从而形成水通道。磷吸附剂是粒状材料，其包括煤灰，火山灰或钢渣，每一种都含有大量的钙，废熔渣或源自煤灰的人造沸石，并产生不溶性的磷灰石氢氧化物。氮清洁剂是有机碳质水清洁剂，其熔点高于待处理废水的水温，被微生物分解以产生氢和有机酸或可生物利用的有机物质并促进反硝化作用。
