Abstract
Description
本出願は、参照により詳細に、および全体として組み入れられる、2007年2月16日に出願された「Process for Treating Sludge and Manufacturing Bioorganically−Augmented High Nitrogen−Containing Inorganic Fertilizer」と題するUnited Status Provisional Application No.60/890,422に対する優先権を主張する。
図3は、固体12%から40%の範囲内、およびより一般的には固体18%から30%の範囲内でAM工場へ送達されるバイオソリッドを示している。この送達は、下水処理場(「WWTP」)からのコンベヤーもしくはパイプを通して、またはトラック、電車もしくは荷船を用いる伝統的輸送のいずれかによってでよい。工場に到着すると、脱水汚泥(301)は、プロセス内のポンプもしくは他の装置を損傷または破壊する可能性がある大きな異物を除去するために集塊破壊機もしくはふるい選別器具を通過させられる。汚泥は、加工処理されるまでは、蓄積および保管のために、サージタンクもしくは貯蔵タンクもしくはサイロまたは現場の底部収納庫(bottom bin)内に配置される。好ましくは送達される固体は、保持タンクもしくはサイロ内に配置され、次に状態調節のために第1混合装置へ搬送されてよい。
Claims (46)
- (a)汚泥を状態調節する工程、
(b)状態調節された汚泥を圧力容器へ加える工程、
(c)反応性混合物を加える工程、
(d)保持期間にわたってストレス条件下で混合物を維持する工程
を含み、工程(a)は汚泥をポンプ搬送可能にさせることを含む、汚泥を処理するための方法。 - 反応性混合物は、アンモニウムスルフェート、アンモニウムホスフェートおよびこれらの組み合わせから本質的になる群から選択される物質の高温塩を含む、請求項1に記載の方法。
- 反応性混合物は、アンモニウムスルフェート、アンモニウムホスフェートおよびこれらの組み合わせからなる群から本質的に選択される物質の高温溶解液を含む、請求項1に記載の方法。
- 反応性混合物は、濃酸および塩基の別個の添加を含む、請求項1に記載の方法。
- 反応性混合物は、濃酸および塩基を用いて事前に処理された汚泥の別個の添加を含む、請求項1に記載の方法。
- 反応性混合物は、事前にアンモニア処理されて状態調節された汚泥および濃酸の別個の添加を含む、請求項1に記載の方法。
