Description

A kind of purging system for the contaminated building clinker of contaminated site
Technical field
The utility model relates to contaminated soil remediation technical field, particularly relates to a kind of purging system for the contaminated building clinker of contaminated site.Particularly relate to contaminated particle diameter builds clinker cleaning disposal at 5 more than cm.The building clinker that in contaminated site repair process, place is original to be built, structures are residual after removing can adhere to contaminated sites thing, as organic pollution and heavy metal contaminants etc.Namely the utility model pollutes clinker for this type of, proposes a purging system, is cleaned up by pollution clinker, again for backfill soil etc., can realize waste resource regeneration.
Background technology
Only have by the slag-soil truck cleaning controlled for the purpose of airborne dust in municipal at present, adopt giant or car washer to rinse the vehicle of transport dregs and dregs, there is no specially for the technology of contaminated site dregs cleaning.
Administer recovery project due to contaminated site to need to remove the original surface buildings of on-site, underground structure and equipment factory building etc. before going into operation, and complete levelling of the land work, inevitably produce a large amount of contaminated Large stone building waste and clinker in this process.In addition, need in later stage project implementing process to carry out screening pretreatment to contaminated soil, a certain amount of clinker can be produced equally.For this part Large stone building waste or clinker, backfill inside after clinker simply being rinsed after engineering mostly is completion to be repaired in the past; Or the roadbed material carried out as place road construction after break process; Or bank up in ward, after utilizing high-pressure washing equipment simply to rinse, carry out outward transport landfill.But above-mentioned process means all exist and cause secondary pollution or pollution range to expand, dispose lack of standardization, the sewage produced in flushing process lacks necessary collection, processes and recycle, and causes the defects such as the wasting of resources.
