Description
この発明の汚泥処理方法は、下水処理場で発生する難脱水汚泥の汚泥処理方法において、下水処理場に流入する汚水中の固形物から所定性状の繊維分を選択的に回収し、回収した繊維分を難脱水汚泥に添加して脱水することを特徴とする汚泥処理方法で、回収する繊維分を脱水助材に最適な性状のものとすることで、脱水性を大幅に向上させることができる。 Sludge treatment method of the present invention is a sludge treatment method of the flame dewatered sludge from sewage treatment plants, and selectively recovering fiber content of a predetermined property from the solids in the wastewater flowing into the sewage treatment plant, the recovered fibers The sludge treatment method is characterized by adding water to difficult-to-dehydrate sludge and dewatering. By making the recovered fiber content optimal for dewatering aids, dewaterability can be greatly improved. .
前記汚水中に含まれる所定性状の繊維分は、前記固形物を調製する調製工程と、前記固形物から所定性状の繊維分を分離する分離工程によって回収され、
前記調製工程は、易分解性有機物と難分解性有機物である繊維分を分離可能な性状へ調製する。前記固形物に希釈水を添加する、もしくは前記固形物を微細化することで分離が容易となる。
前記分離工程は、調整した前記固形分を洗浄水で洗浄して所定性状の繊維分を回収することで、下水処理場に流入する汚水の中から確実に所定性状の繊維分のみを回収することができる。
The fiber content of a predetermined nature contained in wastewater, the preparation step of preparing the solid is recovered by separation step of separating the fiber fraction qualitative shape away from the solids,
The said preparation process prepares the property which can isolate | separate the fiber part which is an easily decomposable organic substance and a hardly decomposable organic substance. Separation is facilitated by adding dilution water to the solid or by refining the solid.
In the separation step, the adjusted solid content is washed with washing water to collect a fiber having a predetermined property, thereby reliably collecting only the fiber having a predetermined property from the sewage flowing into the sewage treatment plant. Can do.
前記調製工程の前段に、所定性状の繊維分より大きい夾雑物を除去してもよく、調製工程及び分離工程の妨げになるものを除去する。 In front of the preparation process, it may be removed from the larger contaminants fiber content of predetermined characteristics, to remove those that impede 及 beauty separation step as prepared Engineering.
Claims (2)
前記固形物を調製する調製工程（３２）と、前記固形物から所定性状の繊維分を分離する分離工程（３３）によって回収されることを特徴とする請求項１に記載の汚泥処理方法。 The fiber component of the predetermined property contained in the sewage is
A preparation step of preparing the solid (32), sludge treatment method according to claim 1, characterized in that it is recovered by the separation step (33) for separating the fiber fraction qualitative shape away from the solid.
