Description

钙离子失衡水质改良方法
技术领域:
本发明涉及盐碱水质的改良方法,尤其是利用化学方法对钙离子失衡型水质进行改良的方法。
背景技术
盐碱水质的改良是盐碱地水产养殖的关键技术。由于盐碱水质的多样性和复杂性,在整个养殖周期中每15天需测定一次水样,只有摸清盐碱水质的属性,针对盐碱水质采取相应的水质改良措施,调整水质才能用于水产养殖业。我国绝大多数盐碱水域的水质中存在钙离子失衡导致pH值、碳酸盐碱度偏高,影响着水产养殖生物,尤其是对虾类的养殖在盐碱水域中的养殖效果,使得这些盐碱水域不能得以很好的利用。国内外目前只有针对养殖水质中的氨氮、硝酸盐、亚硝酸盐、生物耗氧量、化学耗氧量进行改良调控,调控的方法主要是通过换水或投放微生态制剂来降低养殖水质中的氨氮、硝酸盐、亚硝酸盐、生物耗氧量、化学耗氧量,而对水质中钙离子失衡型水质缺乏合适的改良技术手段。盐碱水质中的钙离子是水质中重要水化学因子,除了对水生生物渗透压、虾蟹脱壳有明显影响外,还与盐碱水质中碳酸盐碱度有明显的相关性。目前,一种国产(河北省沧州市方兴化工有限公司生产)赛蓝牌水质改良剂2号,其主要成分是含钙的化学混合物,可用于钙离子失衡水质,但还需要配套的实施方法。
发明内容
本发明需要解决的技术问题是为减轻水质中钙离子的失衡程度,提供一种便于操作的实施方法。
本发明的技术方案包括水样的采取、保存、水质检测和采用以钙为主要成分的水质改良剂,其特征是采取的水样在低于25℃温度下密闭保存;水质中钙离子测定采用络合滴定法,碳酸盐碱度测定采用酸直接滴定法,pH值用酸度计检测,用测定水质中钙离子含量占总含盐量的百分比,确定钙离子失衡程度的级别;并依据钙离子失衡的级别和总含盐量确定水质改良剂的用量;水质改良剂的用量(克/立方米)=[3.68×(级别-1)2-3×级别×(级别-4)]×总含盐量;该用量的水质改良剂溶于水,均匀泼洒在养殖水体中。
本发明通过测定钙离子质量百分比来确定钙离子失衡的级别,并以该级别与总含盐量对应的用量投放改良剂,具有减轻钙离子失衡的程度,控制水质中的碳酸盐碱度,减少碳酸盐碱度对养殖生物的毒性,把钙离子失衡对生物生存生长的影响减少至最低程度的技术效果。
具体实施方式
水样的采取,应根据以下不同条件,分别按相应的要求进行:
水深在1米以下的地表水,水样取自水面下30公分;
水深1米以上的地表水,分别对表层和底层水进行取样;
地下水和井水经充分曝气后取样;
新挖地下水或井水长期不用,必须等水流出5分钟后取样。
水样保存,室温低于25℃时,水样常温密闭保存;
室温高于25℃时,水样放入冰箱冷藏室中密闭保存;
水样保存时间不宜超过48小时。
水质检测的方式:用保存时间不超过48小时的水样进行检测,水质中钙离子测定采用络合滴定法(国标GB7467-87EDTA滴定法),碳酸盐碱度测定采用酸直接滴定法,水质中pH值用酸度计检测,总含盐量测定采用一定量过滤水样在105-110℃加热烘干称量;钙离子质量百分比是指水质中钙离子含量占总含盐量的百分数;
钙离子失衡级别的确定按钙离子质量百分比低于1%,为钙离子失衡水质,根据钙离子质量百分比的高低,钙离子失衡水质分为:
钙离子质量百分比低于1%,高于或等于0.7%,为I级失衡;
钙离子质量百分比低于0.7%,高于或等于0.3%,为II级失衡;
钙离子质量百分比低于0.3%,高于或等于0.1%,为III级失衡;
钙离子质量百分比低于0.1%,为IV级失衡。
对于pH值低于8.6的水质,根据水质中钙离子失衡程度,通过计算确定每立方米水体应投放水质改良剂的用量;
水质改良剂的用量(克/立方米)=[3.68×(级别-1)2-3×级别×(级别-4)]×总含盐量
以钙为主要成分的水质改良剂适用上述计算式得出的用量,将该用量改良剂用水溶解,均匀泼洒在养殖水体中,并开启增氧机搅拌,使改良剂均匀分布在水体中。
由于改良措施受池塘土壤、地质因素影响,因此,采取改良措施24小时后,再检测钙离子浓度和pH值,若碳酸盐碱度高于8,可根据所测钙离子浓度,重新确定钙离子失衡程度,再次对水质进行改良。
本发明适用于pH值低于8.6,钙离子失衡的水质改良,对于pH值高于8.6的钙离子失衡水质,先实施降pH水质的改良技术。对于同时存在其他离子失衡型水质,按其他水质改良相关技术处理。
