Description

Suppression system and suppression method
Technical Field
The invention relates to the technical field of polluted site environment restoration engineering, in particular to a suppression system and a suppression method.
Background
At present, the pollution of polluted sites is serious, and the main pollutants are zinc, mercury, lead, chromium, arsenic and polycyclic aromatic hydrocarbon. The most direct method for solving the problem of the polluted site is to repair the site. The contaminated site remediation technology can be divided into an in-situ remediation technology and an ex-situ remediation technology according to remediation modes. Compared with the ex-situ repair technology, the in-situ technology does not need to build expensive ground environmental engineering facilities and carry out remote transportation on pollutants, and is simple to operate and maintain. However, the in-situ remediation technology is greatly limited by the characteristics of the site, and is difficult to implement on the soil with low permeability and complex geological structure. In addition, the in-situ repair period is long, and the repair effect is difficult to reach an ideal state. In contrast, although the ectopic repair technology has high cost in aspects of excavation, equipment use and maintenance and the like, the repair period is short, and the repair effect is good. The method is matched with the requirement that the polluted site needs to be repaired and developed as soon as possible, and the existing repair technology adopted in the polluted site repair engineering is mostly heterotopic repair.
However, the problems of peculiar smell, dust and the like caused by ex-situ remediation construction are more and more concerned by all parties, and the smooth progress of the remediation engineering of the polluted site and the healthy life of surrounding residents are seriously affected, wherein the problems of peculiar smell volatilization and dust diffusion generated by the procedures of screening and crushing the polluted soil, uniformly mixing the added remediation agent and the like are the most serious.
The closed micro-negative pressure repair workshop is built in the repair field aiming at the more and more field repair engineering with the problems, the contaminated soil is dug and transported to the repair workshop and then is screened, crushed, mixed with the added repair agent and the like, and the influence of peculiar smell volatilization and dust diffusion on the surrounding environment of the field is relieved to a certain extent. However, there are problems with this repair shop during use:
(1) although the influence of peculiar smell and dust on the surrounding environment is relieved by using the repairing workshop, the peculiar smell and dust in the workshop are worse during repairing operation because the repairing workshop is in a closed state during operation. The body health and the working state of repair operators are seriously influenced, the working efficiency of construction machinery is reduced, and the failure rate is greatly increased;
(2) when construction machinery (transport vehicle, excavator and the like) and personnel enter and exit the repair workshop, the corresponding inlet and outlet channels need to be opened. At this time, peculiar smell and a large amount of dust accumulated in the repair shop inevitably escape from the opened channel. Engineering experience shows that short-time and strong peculiar smell and dust diffusion cause adverse effects on the surrounding environment, are not negligible, and easily bring discomfort to surrounding residents, even cause environmental group events.
Therefore, it is urgently needed to develop a suppression system and a suppression method for suppressing the peculiar smell and dust in the repair workshop of the polluted site.
