采用麦饭石和双氧水改善扇贝育苗用水水质的研究

研究了麦饭石和过氧化氢作为水质净化剂对水体中水化因子的调控作用和效果,结果表明:双氧水能有效去除水中有机物,且基本无残留;麦饭石对养殖水体具有双向调节酸碱度的作用,能有效降低水体中的有害物质含量,麦饭石的一次使用量为50 mg/L,一次效应为8天左右。随着使用量的提高,水体中的NH_4~ -N和NO_2~--N的浓度降低的效果更为明显,且效用时间更长,尤其是在水质恶化时其作用更为明显。

Study on the Improvement of Water Quality For the Seed-rearing of Sclailop By Medical Stone and Hydrogen Peroxide

This article studied the function and effect of medical stone and H_2O_2 as water quality dose for hydration factors in water body.The result showed that H_2O_2 solution worked efficiently removing the organic material and without remains;Medical stone could adjust the pH value,reducing the concentration of the harmful material,the concentration of the applying dose was 50 mg/L, and the effective period was about 8 days.The higher the concentration the apparent the effection of decreasing the NH_4~ -N and NO_2~--N,and the longer the effective period.
