Abstract
The invention discloses a contaminated soil repair system. The contaminated soil repair system comprises a landfill layer formed by soil to be repaired, wherein the upper part of the landfill layer is a nitration area; atmosphere is fed into the nitration area as an aerobic area; the lower part of the landfill layer is a denitrification area; the denitrification area is sealed as an anoxic area; a water inlet is formed in the bottom of the denitrification area, and is outwards communicated with a water transmission pipeline; the water transmission pipeline is communicated with a water outlet of an adjusting pool; two water inlets are formed in the adjusting pool; one of the water inlets is communicated with a water pump, and the other one of the water inlets is communicated with a leachate collecting pipe; the leachate collecting pipe is communicated with a three-phase separator; the three-phase separator is arranged at one side of the top of the nitration area; and a water outlet pipeline is arranged at the other side of the top of the nitration area. The technical scheme of the invention is adopted; the aerobic nitration area performs the nitration and the oxidation of organic matters; and the anoxic denitrification area performs the denitrification and the anoxic decomposition of the organic matters, so that the treatment efficiency is high.
Description
Technical field
The present invention relates to fire-fighting equipment field, be specifically related to a kind of contaminated soil remediation system adopting recirculating.
Background technology
Soil pollution can be divided into inorganic pollution and Organic Pollution according to pollutant component.Inorganic pollution comprises the pollution that acid, alkali, heavy metal and the nonmetallic compound such as arsenic, selenium cause; Organic Pollution comprises the pollution that agricultural chemicals, phenols, cyanide, oil, synthetic detergent etc. cause.
Soil pollution can be divided into industrial sites pollution, oil gas field pollution, mining area pollution, Farmland contamination according to the type of contaminatedground.Sometimes also the underground water pollution that soil pollution causes is included in soil pollution category.
Industry and the rough formula development of agricultural are the main causes causing soil pollution.From industrial pollution angle, the heavy metal pollution in soil inorganic pollutant mainly comes from the waste discharge of smeltery, industrial plant such as discharge factory, insecticide factory etc.; Nonmetal arsenic and selenium contamination are mainly from agricultural chemicals and electronics industry etc.; Organic pollution mainly comes from petroleum chemical industry and agricultural chemicals.From agricultural soil pollution angle, the excessive use of chemical fertilizer is the main cause causing soil pollution.
For above-mentioned soil pollution kind, there are multiple reparation means, wherein there is a kind of Bioreactor landfill technology, compared with traditional soil-burial field, bioreactor landfill adds leachate recirculation system, transform leachate collection system, landfill gas collecting system, it stores except function except what have a general soil landfill yard, also by there being object control device, for microorganism provides good growing environment, whole landfill yard is become one " reactor ", thus accelerate the degraded of fill soil Organic substance in water, accelerate the stabilization procedures of fill soil, the stabilization procedures of soil is made to foreshorten to 3-5 from 20-30, thus avoid the long-term supervision after closing and maintenance, landfill yard is had simultaneously store, cut off and pollute, multiple function such as biodegradation and resource recovery.
