Abstract
The invention discloses a process for the online monitoring and the sampling of waste water, which comprises the online monitoring without needing pretreatment of a water sample, the online monitoringwith necessary pretreatment of the water sample, and back washing before sampling. The process for the online monitoring and the sampling of the waste water is simple to operate, not only can accurately collect a representative water sample in the monitored waste water in real time and embody the authenticity and the representativeness of over-standard waste water, but also sets the back washingbefore sampling, thereby avoiding the probability of secondary pollution and the caused problems of pipeline blockages, and ensuring the real-time property and the accuracy of online monitoring data.
Description
Technical field
The present invention relates to a kind of process for online monitoring and sampling of waste water, belong to the effluent monitoring technical field.
Background technology
Enforcement along with national energy-saving and emission-reduction policy, on-line monitoring to industrial waste water water quality seems important day by day, and to key one step that industrial waste water water quality is carried out on-line monitoring be exactly to want to collect representational waste water water sample accurately, in real time, and guarantee that water sample physicochemical property in the pipeline of transmission do not change.
It is too complicated that at present existing sampling flow processs have, be not easy to operation, what have can't gather water sample in real time, the mistiming of sampling is caused the water quality situation that can't truly reflect monitored waste water, what also have can't clean pipeline, causes online monitoring data not have real-time and accuracy.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly can accurately collect the process for online monitoring and sampling of waste water that representative water sample in the monitored waste water and online monitoring data have real-time and accuracy in real time, to overcome above-mentioned existing in prior technology defective.
For achieving the above object, the technical solution used in the present invention is as follows:
Process for online monitoring and sampling of waste water of the present invention, comprise and do not need water sample is carried out pretreated on-line monitoring and need carry out pretreated on-line monitoring to water sample, it is characterized in that: also comprise the back flush before the sampling, promptly on sample lines and connect tap water counter-flushing pipeline and compressed air rinsing pipeline.
Described the needs carried out pretreated on-line monitoring to water sample, is that water sample is at first pumped among the sample reserving groove a by sampling water pump a, then automatically assay determination instrument a by carrying out synchronous The real time measure with monitoring probe that the monitoring interface of sample reserving groove a is contacted mutually; The number of the monitoring probe that monitoring interface that sample reserving groove a is upward set and automatic assay determination instrument a are comprised is complementary; Automatically assay determination instrument a is meant that pH (potential of hydrogen) instrument, conventional Wucan count one or more in analyser, ammonia nitrogen and total blood urea/nitrogen analyzer, chlorine ammonia analyser, ammonium ion analyser, permanganate analyser, total phosphorus analyser, fluoride analyser, chloride analyzer, nitrate analyser, UV organism analyser, copper analyser, basicity analyser and the turbidity analyser.
Describedly need carry out pretreated on-line monitoring to water sample, be that water sample is at first pumped into by sampling water pump b and carries out pre-service in the water sample pretreatment unit, pretreated water sample one road flows among the automatic assay determination instrument b carries out synchronous The real time measure, and another road flows into simultaneously among the sample reserving groove b and keeps sample; The number of the injection port that set monitoring interface and assay determination instrument b are automatically comprised on the water sample pretreatment unit is complementary; Automatically assay determination instrument b is meant one or both in COD analyser and the TOC analyser.
Described sample lines is made up of the UPVC plastic tube.
Compare with existing similar technology, process for online monitoring and sampling of waste water of the present invention is simple to operate, can not only accurately collect representative water sample and instant authenticity and the representativeness that embodies overstandard waste water in the monitored waste water in real time, and set up back flush before the sampling, avoid the possibility of secondary pollution and the line clogging problem that causes, guaranteed the real-time and the accuracy of online monitoring data.
