Online detection method and device for building reclaimed water

Abstract

The invention discloses an online detection method and device for building reclaimed water. The device is mounted in a reclaimed water recycling system and comprises an online residual chlorine detector and an online turbidity detector which are mounted in the same shell; the water inlets of the online residual chlorine detector and the online turbidity detector are communicated with a reclaimed water supply pipe respectively; the water outlets of the online residual chlorine detector and the online turbidity detector are communicated with a reclaimed water recycling pool through return pipes; a bypass pipe is connected between the water inlets of the online residual chlorine detector and the online turbidity detector and the reclaimed water supply pipe connected to the reclaimed water users; the online residual chlorine detector comprises a residual chlorine control chip the control signal output terminal of which is connected with the dosing pump of a chlorination disinfection device through a control signal wire; and the online turbidity detector comprises a turbidity control chip the control signal output terminal of which is connected with an alarm through a control signal wire. Through the invention, the problem that online detection equipment is currently unavailable for the building reclaimed water is solved, and the safe and stable reclaimed water supply can be ensured, thus the method and device provided by the invention are applicable to the reclaimed water systems of buildings and residential areas.

Description

technical field [0001] The invention relates to the on-line detection technology of reclaimed water, in particular to an on-line detection device and method for reclaimed water in buildings. Background technique [0002] The conventional water quality detection method is mature, the detection result is accurate, and the data is relatively stable. It is the most basic water quality detection method at present. However, with the development of the water treatment system, the limitations of this detection method have gradually emerged, mainly in the following aspects: 1) The sampling interval is long, the data analysis and summary are slow, the transmission is not timely, and it is difficult to check the current situation of the reuse water quality Accurately and timely carry out the overall grasp. 2) The dynamic data of changing water quality cannot be obtained timely and accurately. 3) It is difficult for the testing organization to carry out on-site sampling and testing, a...

However, with the development of the water treatment system, the limitations of this detection method have gradually emerged, mainly in the following aspects: 1) The sampling interval is long, the data analysis and summary are slow, the transmission is not timely, and it is difficult to check the current situation of the reuse water quality Accurate and timely overall grasp

2) The dynamic data of changing water quality cannot be obtained timely and accurately

3) It is difficult for the testing organization to realize on-site sampling and testing, only for incoming samples, and cannot guarantee the credibility of water samples

At present, many reclaimed water systems are not in good condition. One of the important reasons is the lack of online testing equipment, poor system supervision, and lack of monitoring of the treatment process, so the normal operation of the water treatment system and the water quality of reclaimed water cannot be guaranteed.

Therefore, it is very important to establish an online water quality detection system for building reclaimed water, which can overcome the shortcomings of poor operation caused by chaotic supervision of reclaimed water in buildings, improve the reclaimed water system in buildings, and promote its application
