Description

The anticipation of a kind of heavy metal industrial effluent discharge beyond standards and sample-leaving system
Technical field
The invention belongs to environmental monitoring field, relate to a kind of monitoring water quality on line and sample-leaving system, especially a kind of for online anticipation and sample-leaving system containing heavy metal industrial effluent discharge beyond standards.
Background technology
Industrial waste water is because pollutant levels are wherein high, if discharge will very easily cause serious harm to ecologic environment in violation of rules and regulations, each state all strictly formulates industrial waste water for this reason emission standard and punishment regulations exercise supervision to industrial pollution source and manage, and most important as the environmental monitoring monitoring technology of supervision and management technical support, continuous, automatic, Real-Time Monitoring that the waste water of industrial pollution source emission is carried out will provide strong law enforcement foundation for supervision and management.
Heavy metal pollution directly has influence on human health and living environment, and the heavy metal ion in water body can cause significant damage to biosome under low concentration, and heavy metal ion monitoring is the important content of water quality monitoring.In the waste water that heavy metal industrial pollution source produces, its concentration of heavy metal ion is high, need after strict processing is up to standard, can discharge.And current monitoring water quality on line technology also mainly concentrates on the monitoring indexes such as COD, TOC, ammonia nitrogen, total phosphorus, very few for the on-line monitoring of heavy metal, this also makes part source steal row to put steathily the lawless person of heavy metal wastewater thereby and be at large.
Due to complicacy and the uncertainty of industrial waste water, industrial waste water on-line monitoring generally need to be sampled automatically to the industrial waste water exceeding standard, and does the analysis that keeps sample.Waste water on-line monitoring is generally comprised of automatic analysis analyzer, automatic sampler and computer controlling center at present, system is arranged near discharge of wastewater mouth, the data of measuring are used Long-distance Transmission Technologies to transfer in time Surveillance center, realize unmanned automatic operation, but there is following problem in these monitoring systems:
One, the sense cycle of analysis analyzer of the overwhelming majority is longer, analyze analyzer measure need to be longer time, when computer controlling center is sent while keeping sample instruction, the water sample of collection has not been to have accepted the identical water sample analyzed, sample distortion causes keeping sample;
Two, all monitoring indexes are to be all taken to for water sampler the water sample of analyzing analyzer at present, and this water sample is generally the sample of sampler (sampling pump) acquisition within a short period of time, its monitor value also can only represent instantaneous discharge value, and cannot represent the general status of discharge in certain period;
Three, the instrument and equipment of existing on-line monitoring is expensive, be difficult to install at the sewage draining exit of each enterprise a set of advanced person's on-line monitoring equipment, cause Some Enterprises supervision not in place, the disappearance of especially medium and small sized enterprises being supervised, if can develop a set of cheap simple and easy on-line monitoring equipment, can greatly improve the coverage rate of sewage draining exit monitoring, guarantee each enterprise's legal discharge;
Four, existing on-line monitoring equipment is strongly professional, and the main technician by environmental monitoring station controls at present, but China environmental monitoring professional and technical personnel wretched insufficiency, non-professional law enforcement for environmental protection personnel cannot get involved professional monitor procedure; If law enfrocement official can monitor the emission status of its local sewage draining exit at any time, first its discharge beyond standards of anticipation, the retention sample that may exceed standard is again delivered to specialized laboratory's batch detection, can greatly promote monitoring and law enforcement dynamics, greatly alleviates environmental monitoring professional's working strength simultaneously.
The industrial waste water composition of its generation of specific factory is relatively stable, the waste water composition discharging after qualified wastewater treatment and relative concentration are stable, concentration of heavy metal ion is wherein also relatively stable, and whether it discharges in violation of rules and regulations therefore can to carry out by the total ion concentration of its waste discharge of monitor full time anticipation.
Conductivity indices is usually used in detecting total concentration or the salt content of water intermediate ion, by conductivity, detect the overall ionic strength that can judge certain solution, conductance measurement technology has quick, stable feature, if be conducive to judge fast the total concentration of waste water intermediate ion for measuring useless electrical conductivity of water.Heavy metal ion is charged ion in solution, large to the ionic strength affect of solution, if discharge in violation of rules and regulations heavy metal wastewater thereby, its conductivity will larger sudden change occur.Therefore,, by detecting the stable Industry Waste electrical conductivity of water of composition and relative concentration, can monitor to a certain extent the emission level of heavy metal wastewater thereby.
Summary of the invention
For above present situation, heavy metal industrial effluent discharge beyond standards on-line monitoring, anticipation and sample-leaving system that the present invention aims to provide a kind of Automatic continuous, analyzes and keeps sample and synchronizes, for discharge of industrial wastes mouth violation exhausting control and the pre-judgement of discharge in violation of rules and regulations, the sample that keeps sample of making to exceed standard has more representativeness, makes heavy metal wastewater thereby exhausting control process more efficient, economical, convenient.
To achieve these goals, solution of the present invention is:
