Description
Technical field
The utility model relates to the small-sized water quality on-line monitoring device of integrated form, is applicable to fields such as environmental protection, water quality monitoring, water analysis, pollution source monitoring.
Background technology
In recent years, along with the deepening continuously of reform and opening-up, city size constantly enlarges, the water consumption sustainable growth of various places infrastructure rebuilding, factory construction, the waste water that is discharged to rivers,lakes and seas increases gradually, environment and ecology destruction in various degree, the serious variation of the quality of water have been caused.Along with the raising of people's living standard, people are more and more higher to the requirement of quality of life, and national environmental pollution situation is also more and more paid attention to, and to environmental monitoring system, especially the control of water quality monitoring system, management and management are also strengthening.
Water quality automatic monitoring device is that a cover is a core with the on-line automatic analyzer device, the comprehensive online auto monitoring system that utilization modern sensor technology, automatic measurement technology, automatic control technology, Computer Applied Technology and relevant dedicated analysis software and communication network are formed.
Existing field water monitoring device can be divided into by use-pattern: portable quick water quality detection instrument and online water quality monitoring system.
Portable field water quality monitoring instrument is easy to carry, make things convenient for field operation, when Sudden Pollution Accident takes place when, can reach the spot rapidly, carry out water quality monitoring targetedly and analysis in the specific region, for example: the portable field water measuring instrument of 85 types of the 6600V2 type multi-parameter water quality monitor of U.S. YSI Inc., the 556MPS type multi-parameter water quality measuring instrument of U.S. YSI Inc. and U.S. YSI Inc., its shortcoming is to be operated by the professional, can't realize long-term on-line measurement.
For addressing the above problem, realize long-term on-line monitoring to open-air water head site, cross section of river, pollution source etc., need set up online water quality monitoring system (also claiming the automatic water quality monitoring station).
Online water quality monitoring system generally can be divided into: probe type, small-sized and medium-sized automatic water quality monitoring station according to what of the difference of monitoring instrument and index.
Probe type monitoring station volume is less, only monitors the conventional Wucan number of water quality usually, for example: the SC1000 multiparameter general purpose controller of U.S. Hash company, can monitor parameters such as dissolved oxygen DO, PH, ORP, conductivity, turbidity, suspended solid, nitre nitrogen.These probes can directly be thrown in and carry out in site measurement in the water body, and system constitutes flexible, can be used for measuring the water quality of the different depth of waters, grasp the real conditions of water body at any time.But probe type water quality monitoring station is not high to the measuring accuracy of water-quality guideline such as COD, ammonia nitrogen, TP, TN, and is not suitable for the bigger water quality of pollution level, therefore is used as early warning more and uses, and water quality data accurately can't be provided.
Parameters such as conventional five parameters (water temperature, pH value, conductivity, turbidity, dissolved oxygen DO) of water quality, ammonia nitrogen are only monitored at small-sized automatic water quality monitoring station usually, for example: the green chest of the YSI of U.S. YSI Inc., and small-sized automatic water quality monitoring station only is applicable to surface water, be not suitable for the bigger water quality of pollution level, important water-quality guideline such as COD, total phosphorus, total nitrogen, heavy metal can't be monitored in this small-sized automatic water quality monitoring station.
Medium-sized automatic water quality monitoring station adopts on-the-spot all kinds of probe types and the cabinet type water quality analytical instrument of industrial computer control to carry out sample detecting usually, possess the complete unit such as water distribution, pipeline back flush, water quality monitoring of adopting, can measure all kinds of important water-quality guideline such as conventional Wucan number, COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metal exactly.But, this common floor area in class automatic water quality monitoring station big (more than 8 square metres), the cost height (1,800,000 yuan/more than standing), need build fixing station, generally can only the monitoring point be set at the several crucial section of trunk river, can't layout on a large scale in two sides, small-sized river, and just can't move once more after the one-step installation, operating cost is also higher.
