在这项研究中，我们评估了硝酸钙试剂可能应用于改善海洋沉积物，这是通过长期珍珠养殖产生的有机物的污染物。利用简单的实验室实验仪器，对硝酸钙试剂进行了初步研究。结果表明：（1）降低了沉积物中AVS的浓度，（2）阻止了H2S从沉积物中的产生，（3）观察到了可能的磷化合物从沉积物中的洗脱控制。在有机污染的海洋沉积物中添加硝酸钙可以增强其絮凝活性。
In this study, we assessed the calcium nitrate reagent for possible application to the improvement of marine sediments, which are pollutants from organic matter produced through long-term pearl culture. A preliminary study was carried out using the calcium nitrate reagent with a simple laboratory experimental instrument. As the results, 1) the AVS concentration in sediments was reduced, 2) the production of hydrogen sulfide from bottom sediments was prevented, and 3) the possible elution control of phosphorous compounds from bottom sediments was observed. The addition of calcium nitrate to the organically polluted marine sediments could enhance the denitrifying activities.
