Abstract
The invention provides a method for spraying a soil remediation agent by using a spraying system. The method comprises the following steps: (1) arranging a fixed point in the center of a contaminated site, arranging a hollow tube provided with a micropore drip irrigation hole and made of a stainless steel or PVC material on the fixed point; (2) driving a drip irrigation device by power to rotate along the fixed shaft at a uniform speed, and setting the rotation speed, flow and operation time of the drip irrigation device in advance; and (3) connecting the bioremediation agent to the drip irrigation device and spraying the bioremediation agent onto the contaminated soil, so as to remediate soil on the contaminated site. The device provided by the invention has the advantages of automation design, convenience for operation, no complex processing equipment, low cost, usage range adjustable according to the size of the contaminated site and wide scope of application.
Description
Technical field
The present invention relates to soil remediation technology, what be specifically related to is a kind of method of utilizing sprinkling system to spray biological prosthetic microbial inoculum.
Background technology
In recent years, along with China's economic development and city layout adjustment, the enterprise of a large amount of discharge such as many chemical fertilizer factories, insecticide factory, chemical plant organic waste moves away from down town, there is a large amount of " palm fibre ground " (abandoned, the front industry and commercial land and the facility that leave unused or do not re-use).Wherein, the concentration of part organic contaminants in soil is very high, and some pollutant even migrates to underground water and diffusion causes wider pollution.These soil organic pollutants mainly comprise petroleum hydrocarbon, Polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbon (PAHs), chlorinated solvents, explosive, agricultural chemicals etc., are all much wherein the materials of " teratogenesis, carcinogenic, mutagenesis ".These pollutants in soil may enter human body by approach such as direct contact, breathing and food chains, have potential human health risk.According to national relevant regulations, these organic polluted soils need to carry out environmental assessment and repair and could again come into operation afterwards according to pollution condition.Therefore, carry out the reparation research of organic polluted soil, the key technology of development organic polluted soil reparation is very urgent in China.
At present, the kind of the soil remediation technology of having developed is in the world a lot, as stable/curing technology, Landfill, hot analytic technique, water-washing technique, biological prosthetic etc.From renovation technique, be mainly divided into original position reparation and showering.The biological prosthetic phytoremediation, microorganism of generally can being divided into repaired and combines the types such as reparation.Compare with other method, bioremediation technology has the advantages such as low, the effective and secondary pollution of cost is few, therefore at home and abroad causes in recent years widely and pays close attention to.
But bioremediation technology also exists some problems in applying at present.For example, also lack the design to biological prosthetic reagent spray appliance at present.
Summary of the invention
For overcoming deficiency of the prior art, the invention provides a kind of method of utilizing sprinkling system to spray biological prosthetic microbial inoculum, solved the difficult problem in existing contaminated soil reparation.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Utilize sprinkling system to spray a method for soil remediation reagent, comprise the following steps:
Step 1) central authorities at contaminated site establish a fixing point, and the hollow tube of stainless steel or PVC material is arranged on fixing point, and hollow tube is provided with the drip irrigation mouth of micropore;
Step 2) drip irrigation appliance at the uniform velocity rotates along fixed axis under the driving of electric power, sets in advance rotating speed, flow, the running time of drip irrigation appliance;
Step 3) biological prosthetic microbial inoculum is connected with drip irrigation appliance, is sprayed onto on contaminated soil, carry out the soil remediation of contaminated site.
Further, biological prosthetic microbial inoculum is for having microbial culture medium or the zymotic fluid of degradation capability to organic pollution.
Compared with prior art, the present invention has following beneficial effect:
1, present device the Automation Design, easy to operate;
2, without complicated treatment facility, cost is low;
3, the scope of application can regulate according to the size of contaminated site, is widely used.
