Abstract
A simulation reactor for bioremediation of organic contaminated soil in extreme environments is particularly used for bioremediation of soil contaminated with high-temperature petroleum. The reactor mainly consists of a heating system and a reactor body, the heating system adopts heat conducting oil to transfer heat, and simultaneously the reactor utilizes step gradient temperature control to simulate high-temperature drought soil environments so that each step is provided with one independent heat conducting oil heating system. The simulation reactor can not only simulate a single extreme soil environment but simulate various extreme soil environments so as to reflect actual conditions of longitudinal distribution of soil and vividly simulate actual field bioremediation conditions, thereby obtaining excellent bioremediation process parameters.

Technical field
The utility model relates to the analogue reactor of soil organic contamination biological restoration under a kind of extreme environment, belongs to the organic contamination biological restoration device, the particularly biological restoration of high temperature oil-polluted soils of simulating extreme soil actual conditions.The reactor of this device mainly is made up of heating system and reactor body two large divisions, wherein heating system adopts conduction oil to conduct heat, simultaneously carried out the segmentation gradient temperature control in order to simulate the high temperature and drought soil environment, every section all has the relatively independent conduction oil heating system of a cover;
Background technology
In organic polluted soil, oil pollution accounts for significant proportion.China breaks through 1 * 10 from crude output in 1978
8T high point and having become since one of the world ten big oil-producing countries, oil-polluted soils nearly 1 * 10 is produced in existing more than 400 of the oil gas field of exploration and development and oil-gas reservoir per year
5T, the accumulative total stacking measures nearly 5 * 10
5T.With the oil field is example, and every mouthful of oil well contaminated land area is 200-500m
2, the total oil well 2 * 10 in the whole nation
5The t mouth, the soil pollution that causes thus can reach 8 * 107m
2, this digital every year is also in growth.1998, national oil, Petrochemical Enterprises were produced oil-containing solids refuse amount and are reached 4.29 * 10
6T, utilization rate is lower than 50%, causes soil pollution can reach 3.3 * 10 thus
6Hm
2There is 6 * 10 every year in China
5The t oil enters environment through approach such as run, drip, leak, causes soil pollution.Along with the development of petroleum industry, the soil oil pollution constantly enlarges.Oil-polluted soils being handled, made the edaphon recovery technique under its standard that reaches recycling in the short period of time, particularly high temperature and drought environment, is problem demanding prompt solution in the contaminated soil governance process.The index of correlation that edaphon is repaired under the different high temperature and drought environment has bigger difference, and the simulation that therefore needs chamber by experiment to carry out extreme conditions such as high temperature and drought obtains relevant basic data, for field repair provides technical guarantee.
At present, the research that the organic pollution simulation is repaired under the relevant both at home and abroad extreme environment is carried out seldom, particularly at the technological parameter Study on Conditions of the biological restoration of petroleum hydrocarbon class pollutant matter in high temperature, arid or high saline environment.Welander, people such as U repair the microorganism simulation of organic polluted soil under the low temperature environment and have carried out relevant research, crude oil pollution soil is used group technology: add the biological restoration experiment that fertilizer and ventilation oxygen supply have been carried out 6 months by a definite date, to the physicochemical property of soil, micro organism quantity and petroleum hydrocarbon content have carried out corresponding mensuration; And the research work of laboratory simulation reparation is carried out at present and not under high temperature and drought or the high saline environment, and the subject matter of existence is can't the real simulation soil environment, causes the simulation process parameter can't directly apply to field experiment.
Summary of the invention
The analogue reactor that the purpose of this utility model provides soil organic contamination biological restoration under a kind of extreme environment with regard to being to avoid above-mentioned the deficiencies in the prior art part.For the extreme soil environment of real simulation, remedy simulation and repair the deficiency that reaction acquisition technological parameter can't directly apply to field experiment, analogue reactor described in the utility model mainly is made up of heating system and reactor body two large divisions, wherein heating system adopts conduction oil to conduct heat, simultaneously carried out the segmentation gradient temperature control in order to simulate the high temperature and drought soil environment, every section all has the relatively independent conduction oil heating system of a cover; This analogue reactor is to be made of top cover, reactor and bottom gas distribution filter layer three parts, its major technology characteristics are that top cover (9) places the top of reactor, gas distribution filter layer (13) places the bottom of reactor, reactor itself is again to be in series up and down by reactor I section (10), reactor II section (11) and reactor III section (12), thereby makes five parts form closed system.
In order to embody design philosophy of the present utility model better, the inventor is provided with air inlet (3), water inlet (2) and exhaust outlet (1) on top cover top; Every section reactor is provided with conduction oil inlet (4), conduction oil outlet (5) and sample tap (8), and every section conduction oil inlet (4) and conduction oil outlet (5) have heating control system all relatively independently; The gas distribution filter layer that is positioned at the bottom also is provided with inflation inlet (6) and percolate floss hole (7).
