某煤矿矿井水深度处理项目采用预处理、深度处理、浓盐水零排放处理三段工艺，工艺分别如下：

1、预处理工艺：采用混凝+沉淀+过滤+消毒；

2、矿井水深度处理工艺：采用超滤+反渗透；

3、浓盐水零排放处理工艺：采用浓缩+蒸发+结晶处理工艺，其中水处理系统为三段，即一段软化除硬工艺段、二段膜浓缩减量段、三段蒸发结晶段。

TCSON-SDI-FA6120全自动在线SDI分析仪应用于RO反渗透装置母管，用于监测RO反渗透装置进水SDI（污染指数）指标。

仪表采用全自动在线运行方式，具备连续自动测量、自动调压、自动更换膜片等功能，实现了现场SDI（污染指数）连续精准测量和无人化值守。

The advanced treatment project of mine water in a certain coal mine adopts a three-stage process of pretreatment, advanced treatment and zero discharge treatment of concentrated brine. The processes are as follows:

1. Pretreatment process: Coagulation + sedimentation + filtration + disinfection are adopted;

2. Advanced treatment process for mine water: Ultrafiltration + reverse osmosis is adopted;

3. Zero-discharge treatment process for concentrated brine: A treatment process of concentration + evaporation + crystallization is adopted. The water treatment system consists of three sections: the first section is the softening and hardening process section, the second section is the membrane concentration and reduction section, and the third section is the evaporation and crystallization section.

The TCSON-SDI-FA6120 Automatic online SDI analyzer is applied to the main pipe of the RO reverse osmosis device and is used to monitor the SDI (Contamination Index) index of the feed water of the RO reverse osmosis device.

The instrument adopts a Automatic online operation mode and is equipped with functions such as continuous automatic measurement, automatic pressure regulation, and automatic diaphragm replacement, achieving continuous and precise SDI (Pollution Index) measurement on-site and unmanned operation.
