Abstract
【解決手段】廃水処理設備における最初沈殿池から発生する初沈汚泥と最終沈殿池から発生する余剰汚泥とを混合して貯留し、この混合汚泥に凝集剤を添加して汚泥粒子を2〜4mmの大きさのフロックとなす1次凝集処理を行い、次に1次凝集処理を終えた混合汚泥をその汚泥濃度が6〜8%となるように濃縮処理し、次いで濃縮処理後の混合汚泥に凝集剤を添加して汚泥粒子を0.5〜3mmの大きさのフロックとなす2次凝集処理を行い、さらに2次凝集処理を行った混合汚泥を脱水処理を施すことを特徴とする汚泥の処理方法。

Description
種類の汚泥が大量に発生することになり、これらの汚泥は最終的に水分濃度が20〜30%(含水率70〜80%)程度の脱水ケーキにいたるまで濃縮、脱水処理が施されて減容化されることになるが、その際にコストを含めていかに効率的に処理するかがこの技術分野における大きな課題のひとつとなっている。
