Abstract

一种初步净化海水的方法,包括以下步骤:①将风化煤粉碎至60目以上;②取一份99.5%的浓硫酸与十份水混合均匀,稀释后的硫酸加入至上述风化煤中混合,所述加入比例为一份风化煤加一份稀释后的硫酸,在封闭状态下放置5~7天后,烘干至含水30~35%;③将上述处理烘干后的风化煤按五百份海水加一份风化煤的比例加入至海水中,在10~60℃的条件下,放置五天,前三天每天搅拌二次,后两天静置;④最后将海水中出现的沉淀物过滤后即可。利用本发明初步净化海水的方法处理后的海水,可以直接用作工业用水,也可经过海水淡化设备淡化后用于生活用水,其方法简单易行,成本低,不需特殊设备,大大降低了淡化时堵塞过滤膜的机率。

Description

初步净化海水的方法
技术领域
本发明涉及一种海水处理方法,特别是涉及一种初步净化海水的方法。
背景技术
目前,地球表面的水其中97.5%是含有盐分的海水,只有少量2.5%是淡水,而淡水中之98%是存在于南北极及冰岛的冰,且由于人口增加的生活废水、工业化后所制造出来的大量污水、原始雨林被大量不当的砍伐,使地球生态环境破坏无遗,温室效应日渐严重,水资源日益减少,海水的开发利用是迫在眉睫的事情,但是为了开发利用海水,人类还面对着许多困难,困难之一是海水组成十分复杂;困难之二是海上运作困难,海水淡化费用昂贵,特别是现有的海水淡化设备处理海水量有限,且因为主要是采用过滤的方法净化海水,其过滤膜极易被海水中的杂质堵塞,不能长时使用。
发明内容
本发明所解决的技术问题是提供一种初步处理净化海水、使海水淡化时不易堵塞设备的初步净化海水的方法。
一种初步净化海水的方法,包括以下步骤:
①将风化煤粉碎至60目以上;
②取一份99.5%的浓硫酸与十份水混合均匀,稀释后的硫酸加入至上述风化煤中混合,所述加入比例为一份风化煤加一份稀释后的硫酸,在封闭状态下放置5~7天后,烘干至含水30~35%;
③将上述处理烘干后的风化煤按五百份海水加一份风化煤的比例加入至海水中,在10~60℃的条件下,放置五天,前三天每天搅拌二次,后两天静置;
④最后将海水中出现的沉淀物过滤后即可。
其中所用的风化煤含腐植酸20%以上,最好在30%以上。
利用本发明初步净化海水的方法处理后的海水,可以直接用作工业用水,也可经过海水淡化设备淡化后用于生活用水,其方法简单易行,成本低,不需特殊设备,所用的风化煤可回收再次利用,处理过的海水pH值为7.1,基本为中性,海水中的重金属杂质均可沉淀下来,大大降低了淡化时堵塞过滤膜的机率。
具体实施方式
采用河北省唐山地区采集到的风化煤,经检测其含腐植酸20.24%,含有机质31.12%,将所述风化煤粉碎至60目以上;将一份99.5%的浓硫酸与十份水混合均匀,稀释后的硫酸加入至上述风化煤中混合,所述加入比例为一份风化煤加一份稀释后的硫酸,在封闭状态下放置5~7天后,烘干至含水30~35%;接着将上述处理烘干后的风化煤按五百份海水加一份风化煤的比例加入至海水中,在20℃的条件下,放置五天,前三天每天搅拌二次,后两天静置;最后将海水中出现的沉淀物过滤后即可。
将此海水中的提取物送样化验,依据HBS001.16-2005标准,采用PGS-2二米光栅光谱仪在24℃,湿度50%的条件下,测其结果见表1:

从测量结果可以看出,本方法可以将海水中的杂质元素基本提取出来,共提取出了26种元素,其中包括一些稀有金属元素和重金属元素,处理后的海水pH值降至7.1,已符合工业用水的需要,其盐分基本没有去除,故经淡化处理后即可作为生活用水使用。
以上所述的实施例仅仅是对本发明的优选实施方式进行描述,并非对本发明的构思和范围进行限定,在不脱离本发明涉及方案前提下,本领域技术人员对本发明的技术方案作出的各种显而易见的变型和改进,均应落入本发明的保护范围,本发明请求保护的技术内容,已经全部记载在权利要求书中。
