Description

Mobile off-line SDI measuring device

Technical Field

The utility model relates to a SDI surveys technical field, is a portable off-line SDI survey device.

Background

The water pollution index (SDI) is an important parameter of water quality index, and represents the content of particles such as particles, colloids and the like in water, and is generally used for evaluating or measuring the degree of water pollution. By measuring SDI values of different stages of the water treatment system such as raw water, before and after sand filtration, before and after activated carbon, before and after ion exchange, before and after reverse osmosis or a precision filter and the like, the effective operation of the water treatment system can be effectively monitored, and whether each process step is normal or not can be judged. Generally, the lower the SDI value, the better the water quality. The SDI value is measured in the production running process, so that the reason of the abnormal water treatment system can be correctly judged, and a method for solving the problem can be found.

Particularly, in the reverse osmosis water treatment process, SDI is one of important indexes for determining the water inflow of a reverse osmosis system, is a main means for detecting whether the water outlet of a pretreatment system meets the requirements of reverse osmosis water inflow, and is of great importance to the service life of the reverse osmosis system.

In general, when a water quality SDI value is measured, a medium needs to be kept at a certain pressure and flow rate for a period of time, and when the pressure and the flow rate of the medium do not meet the measurement condition requirements, SDI measurement cannot be performed, so that common water quality sampling detection points are all arranged at a design stage, the positions are basically fixed, and analysis points are limited. When the water treatment system is abnormal in the production operation process, the sampling site cannot be flexibly selected to carry out sectional detection and analysis on the water quality of the system, and the process step which is abnormal cannot be quickly judged, so that the stable high-quality operation of the production system is not facilitated.
