摘要：

Manganese-copper　composite(MCC)　algaecide　was　prepared　by　permanganate　and　acid-soluble　copper　chloride.　The　effectiveness　of　MCC　on　microcystis　aeruginosa　removal　and　the　effective　period　of　MCC　were　studied,　pH　influence　on　the　water　sample　was　inspected,　and　the　feasibility　of　MCC　as　a　new　algaecide　was　discussed.　The　results　showed　that　the　optimum　ratio　of　copper　reagent　A　and　manganese　reagent　B　was　0.5~1.5:1.0.　Removal　rate　of　turbidity,　OD420　and　chlorophyll　a　were　67.82%,　77.98%　and　97.04%　respectively　during　10　days　of　MCC　dosing.　Turbidity　and　chlorophyll　a　were　reduced　to　6.16NTU　and　1.048　μg　·　L-1,　with　removal　rate　of　77.4%　and　99.48%　after　MCC　dosing　of　16　days.　pH　value　of　water　sample　was　reduced　with　increasing　ratio　of　copper　reagent　within　MCC,　pH　value　is　7~8　at　the　best　composited　ratio.
