Description
本发明涉及管网水质检测领域,尤其涉及一种针对排水管网水质采样的装置及方法。
定期检测排水管网检查井内的水质,是诊断排水管网是否有地下水渗入的重要手段,为形成较好的对照结果,要求每次能采集到同一位置要求的水样。但随着管网的运行,检查井内部会逐渐的堆积形成沉积物,且检查井内沉积物的深度分布不同,这样在后续对同一位置进行水质采样时,常规市售水质采样器主要采用绳索水质采样器,其工作深度不易控制,无法很好的保证每次所采集到的水样为同一取样深度的水样,进而影响后续检测的结果,导致检测结果出现偏差;具体参见图1,为检查井没有沉积物时的水位高度,此时采用绳索水质采样器所采集的是水位高度为H的水样;具体参见图2,当检查井内有沉积物时,检查井内的水位会增加,此时采用绳索水质采样器所采集的是水位高度为H1的水样,而采用的要求实质上需要采集原有的水位为H的水样,这样就导致了两次采集到的水位并非同一高度水位。此外,在采用过程中常常因搅动沉积物,而使得每次采样都会因不同含量的沉积物而影响到水质数据质量。
例如现有的,CN210322446U,一种排水管网用采样装置,其通过在伸缩杆的末端设置吊桶来进行排水管网的采样,在采样过程中,无法精确控制每次取样的深度。
虽然在CN209356242U,一种污废水水质采样装置,其通过在斜杆段的末端设置采样容器,进而达到采用的效果,但是在采样过程中,同样无法精确控制每次取样的深度。
发明内容
针对上述问题,本发明的目的在于提出一种针对排水管网水质采样的装置及方法,此装置能够很好的适用于管网有不同厚度沉积物的水质采样,保证了在采样过程中,每次都能够采集到设定好的同一深度位置的水样,保证了采样精度,进而保证了后续计算精度和结果。

实施例2:
采用一种针对排水管网水质采样的装置进行水质采样的方法,包括以下步骤:
步骤一,沉积物6的深度检测:
采用市售的沉积物柱状采样器4测定检查井5内沉积物6的深度,将沉积物6的厚度计为h;同时测定检查井5内部水位高度为B;
步骤二,设定采样高度:
预先根据采样要求,设定需要的采样深度A,采样深度A是从检查井5的底部到采样点的高度值;
步骤三,采样桶1安装高度的标定:
取出支撑器2,根据所测定沉积物6的厚度h,在支撑器2的刻度线202上作出标识位置,此标识位置要保证安装采样桶1后,锥形桶体109底端距离圆柱杆201底端的距离D要大于沉积物6的厚度h,进而避免锥形桶体109的底端碰触沉积物6,即D≥h;
步骤四,采样桶1的安装高度确定:
根据步骤二中所设定的采样深度A,此采样深度A以采样桶1的第一进水口101和第二进水口105的顶端作为标记线,将采样桶1在支撑器2上安装高度定为A,并保证A-C≥h,C为采样桶1的高度;
步骤五,采样桶1的安装固定:
根据步骤四中所确定的安装高度,将采样桶1安装在支撑器2的圆柱杆201上,再通过螺母103将采样桶1锁定在支撑器2上;
步骤六,提升机构3的组装:
根据检查井5的深度,组装提升机构3,将多根竖杆301通过螺纹柱303和第二螺母套306之间的螺纹配合,逐节安装至工作高度,再将提升机构3与支撑器2相组装,再安装横杆304,形成提升机构;
步骤七,水质采样:
带采样装置安装完成之后,手握提升机构将采样装置插入检查井内,并使得圆柱杆201插入到检查井5的底端,然后采集固定深度A位置的水样;
步骤八,水样取出:
采样后,将整个采样装置提出检查井,先将采样桶1底部的沉淀体底部的干扰性沉积物排出,再将水样注入储存瓶送实验室检验;
步骤九,采样装置的回收:
完成采样后,将采样装置组件逐个拆解,安放于组件箱内,便于下次使用。
进一步的,当A-C<h时,换用另一型号的采样桶1,选取采样桶1的高度为C1,并保证A-C1≥h。通过上述的布置,以防止采样桶1底端对沉积物产生扰动。
