The invention provides data for disclosing an underground migration and transformation rule of the volatile organic pollutants and provides technical support for monitoring the soil environment and controlling and treating the pollution.
Description
Technical field
The invention discloses a kind of underground volatile organic matter in-situ test system, belong to the resource and environment technical field.
Background technology
The land pollution of China especially plough pollute more and more serious.The not treated river and the face of land of directly being discharged into of a large amount of industry and sanitary wastewater, waste residue, bring great pollution to soil, national contaminated arable land has 1.5 hundred million mu approximately at present, sewage irrigation is polluted and is ploughed 3,250 ten thousand mu, solid waste is stored up occupation of land and is ruined 2,000,000 mu in field, add up to account for more than 1/10 of the Chinese arable land total area, and increasing with fast speeds every year.
According to " for the first time national pollution source generaI investigation communique ", 2092.81 hundred million tons of national all kinds of sources wastewater emission amounts, toxic emission total amount 637203.69 billion cubic meters.Between the coming years, country strengthens the reduction of discharging and the improvement work of above pollutant with emphasis, preserves the ecological environment, particularly soil environment safety.
Along with China's economy and the society flourish, in the urbanization process that continues, the planning again of strategic layout is carried out in each big city, and a large amount of factories move, enterprise leaves over down many contaminated places, and the area of China " poison ground " is equivalent to 12 Beijing according to statistics.When these soils are developed again, if it is not done environmental impact assessment and exploration, and take the means of repairing accordingly, can stay the serious environmental risk, Wuhan at the beginning of 2007 " poison ground " incident has just caused serious casualties and huge property loss.
Volatile organic contaminant is as the important source of soil pollution, have adsorbability, unevenness, disguise and hysteresis quality, have only by pedotheque is tested and to find its harm, the organism that is adsorbed in soil surface is difficult to detect, must could accurately test its concentration and kind by means such as heating, therefore organic pollution of soil generally gets the brush-off, simultaneously, often needed a quite long process from polluteing generation " disastrous effect ", its health hazard to human body is very big.Strengthen soil environment monitoring, improve the precision of test, formulate corresponding effective measures according to test result and carry out soil remediation, this is extremely urgent for the protection people's life safety present situation in short supply with alleviating land resource! Therefore, provide a kind of easy to use, powerful volatile organic contaminant test macro, not only help preserving the ecological environment and people's life safety, and can provide data and technical support for the research and the reparation of pollutant soil transmission rule.At present, more or less there are the problem of the following aspects in domestic and international dependence test system that researches and develops and equipment:
(1) the underground system itself is the integral body of a balance, and the dystopy test will change its correlation parameter, the data deficiency authenticity.
(2) underground pollution thing transmission is a dynamic changing process, and is bigger with change in depth, the too little impact analysis of MTD comprehensive.
(3) Xi Fu volatile organic matter has the character of meeting the heat volatilization, and with variation of temperature volatile quantity difference, normal temperature is tested its precision and be cannot say for sure to demonstrate,prove.
(4) most of devices fail to realize that data sync gathers automatically, temperature control and flow rate test function, and this will influence test period and interpretation of result.
Along with country grows with each passing day to the demand of environmental information, need a large amount of relevant environment monitoring equipments, the enforcement performance that emphasis need have independent intellectual property right is good, automaticity is high and the pollutant proving installation and the system of perfect function.For organic pollution of soil, then need one to overlap original position, the testing apparatus that integrates heating, temperature control and synchronous data sampling or the system of the accurate test contaminant kind of energy, concentration and flow etc. under different depth and temperature change.
