基于壳聚糖净水剂的净水设备 技术领域
本发明涉及净水设备领域，特别是涉及基于壳聚糖净水剂的净水设备。
背景技术
保护生态环境，因而越来越受到人们的重视，虽然再生造纸废水的污染负荷相对较轻，但仍远远超过排放标准，若直接排放，将对环境带来污染和危害，随着再生造纸利用比例的不断提高，其废水这一污染源已引起了人们的重视，目前对这类废水常用的处理方法是絮凝法，使用的混凝剂主要有两大类：一类是无机盐类，如铝盐及其共聚物，单独使用无机混凝剂，剂量大，处理费用高；另一类是有机高分子类，如聚丙烯酰胺及其衍生物，净水效果好，但存在降解难、残留单体有毒等问题。
壳聚糖是甲壳素脱乙酰基化的产物，它具有很多特性，如可生物降解、具有广泛的来源、价格低廉等。由于壳聚糖的结构特征使其具备优异的吸附性能，特别适合作为絮凝剂及螯合吸附剂，广泛应用于水处理领域力，壳聚糖还能抑制水中微生物的繁殖和生长，具有一定的杀菌作用·壳聚糖无毒，对动、植物无害，用其作为絮凝剂的污泥可作肥料，在环境保护方面具有广阔的应用前景。
在公开号“CN104879851A”公开的“杀菌空气净化器”，在公开号“CN107540173A”公开的“一种废水自动脱色装置”，包括过滤池， 所述过滤池与第一沉淀池相连通，所述第一沉淀池与一脱色池连通，所述脱色池通过第三控制阀与脱色剂发生装置连通；所述脱色剂发生装置包括甲醛滴入装置、反应器、尿素滴入装置、催化剂滴入装置、加热器和总控制器；所述甲醛滴入装置、尿素滴入装置、催化剂滴入装置和加热器均受控于所述总控制器。本发明能够实现脱色剂的自动化制备，从而与废水处理的其它工艺一起实现废水处理的全程自动化。
在进行净水过程中，废水在进入净水设备的时候，现有技术通常使用弯管进行输入，减小水流速度，但是在弯管的弯曲段承受压力较大，且水流也在弯曲段进行转向，弯曲段则承受更大的压力，而且壳聚糖对于不同废水的处理难以对症下药，导致废水处理效率低下，且捕集水中污染物质的能力较差。

本发明具有以下有益效果：
1、本发明通过分流部设置在进水管的弯曲段，弯曲段是进水管中水流进行转向的起始段，而弯曲段也是受力最大的管体，分流部的各个分流板之间具有间隙，且可以旋转，在进行分流的过程中，水流使分流板旋转到面对水流的方向，而且水流从分流板的间隙流出，减小了水流速度，且在水流变向时，提供朝弯曲方向的力，使水流更轻松变向，减小弯曲段的压力，保护弯曲段，且进水管的多个弯曲，也能增加水流的时间，使废水较慢到达净水箱中，保护废水中的物质不 会溅射出箱外，保证周围环境的安全。
2、本发明通过设置壳聚糖与NaOH及CS2混合制作而成絮凝剂，改变其反应温度，得到三种不同的絮凝剂，三种絮凝剂分别对不同废水产生不同的净化作用，一号絮凝剂，除油率高达98％，除悬率54％处于中等水平，适用于油性废水，其中的悬浮物较少，可达到优秀的除油水平，良好的去除悬浮物的水平，二号絮凝剂，除油率81％以及除悬率83％均处于优良水平，适用于油以及悬浮物都较多的废水，可达到优良的除油水平以及优良的去除悬浮物的水平，三号絮凝剂，除悬率高达99％，除油率58％处于中等水平，适用于悬浮物较多的废水，其中的油脂较少，可达到优秀的去除悬浮物水平，良好的去除油脂的水平，改善了捕集水中污染物质的能力。
当然，实施本发明的任一产品并不一定需要同时达到以上所述的所有优点。
