结合以下实施例对本发明作进一步描述。The present invention is further described in conjunction with the following examples.
实施例1。Example 1.
一种EDR电渗析净水系统，如图1所示，设置有EDR单元100和监测EDR单元100内的电流的电流监控单元200；A kind of EDR electrodialysis water purification system, as shown in Figure 1, is provided with the current monitoring unit 200 of the electric current in the EDR unit 100 and monitoring EDR unit 100;

TDS(Total dissolved solids)，称为总溶解固体或溶解性固体总量，指的是水中全部溶质的总量，包括无机物和有机物两者的含量，例如：Ca2+、Mg2+、Na+、K+等离子。一般情况下，TDS的值越高，表示水中含有的溶解物越多。具体的，TDS也与电导率存在必要的联系，电导率越高，表示水中的含盐量越高，TDS也就越高。TDS (Total dissolved solids), called total dissolved solids or total dissolved solids, refers to the total amount of all solutes in water, including the content of both inorganic and organic substances, such as: Ca 2+ , Mg 2+ , Na+ , K+ plasma. In general, the higher the TDS value, the more dissolved substances in the water. Specifically, TDS also has a necessary relationship with conductivity. The higher the conductivity, the higher the salt content in the water, and the higher the TDS.
需要说明的是，本发明中的EDR单元100内的含盐量能够影响整体的电阻。当给EDR单元100施加一定的电压时，通过监测EDR单元100内的电流满足目标电流范围时，能够实时判断EDR单元100内纯水的电导率，即含盐量TDS值。It should be noted that the salt content in the EDR unit 100 of the present invention can affect the overall resistance.
