含氧化铁炉渣、锰矿粉及漂白粉对虾池底质的净化作用

The Purification of the Residues of Shrimp Ponds by Iron Ore Sediments, Manganese Powder and Bleaching Powder

研究同安丙州、厦门高崎虾池底质添加炉渣、锰矿粉及漂白粉氧化性物质,通过缺氧培养、测定了虾池沉积物间隙水Fe(Ⅱ)、Mn(Ⅱ)的变化速率,结果表明:漂白粉有很强的氧化作用,能迅速净化虾池底质,但容易失效,炉渣、锰矿粉中Fe_2O_3、MnO_2的氧化性较漂白粉弱,但具有反复循环净化虾池底质的作用,且能较长时间抑制虾池老化、净化消毒水质,同时,护渣是工厂废料,价格低廉,作为虾池底质净化剂可变废为利。

This paper is on a test of residues of the shrimps ponds in Bingzhou,Tongan and Gaoqi,Xiamen,in which oxides such as iron ore sediment,manganese powder and bleaching powder were added. The rate of variation at which the shrimps ponds residues release Fe2+ and Mn2+ was determined through oxygen deficit cultivation. The result shows:first,bleaching powder has a strong oxidation. It can rapidly purify shrimp ponds residues, but the period it affects is relatively short and it easily loses its effect. Second,the Fe2+ and Mn2+ in iron ore sediments and maganese powder have a weaker oxidation than bleaching powder ,but they can circulate cleaning the shrimps ponds residues, restrain the ageing of the shrimps ponds in a relatively long period since purify and disinfect the water quality. And also,since iron ore sediments and maganese powder are factory wastes,haveing cheap price and a great practicality,they can be used as the disinfectant of shrimps ponds residues.
