What is in situ soil remediation

In situ soil remediation refers to the soil remediation technology that does not move contaminated soil, and directly repairs or processes the contaminated soil in the site,
it has the characteristics of low investment and little influence on the surrounding environment.

In situ soil remediation technology mainly in situ leaching, vapor extraction (SVE) and multi phase extraction (MPVE), gas injection (IAS), biological degradation, in situ chemical oxidation (ISCO), in situ chemical pollutants reduction, fixation, phytoremediation and so on. In situ soil remediation requires local conditions, flexible combination of time, pollution, geological conditions, ground facilities, summed up the most economical and practical methods of repair, and improve technology in more research, making the in situ remediation technology more economical and effective.

In situ soil remediation techniques include in situ physical remediation, in situ chemical remediation and in situ bioremediation.

In situ soil physical method include soil vapor extraction technology, electric separation technology, modified method and heat treatment method.

Chemical remediation method of in-situ soil remediation method mainly includes in situ soil leaching, in situ chemical oxidation, in situ chemical reduction method and in situ chemical solidification / stabilization technology.

In situ bioremediation includes microbial remediation and phytoremediation.

Treatment of soft soil foundation by high pressure injection method

图片
The method is to use a drilling machine to inject a nozzle pipe into the soil layer. The slurry or water is ejected from the nozzle at high pressure to form a jet stream to destroy the soil layer. When the energy of high speed jet fluctuation was shaped, the dynamic pressure is greater than the strength of soil structure, soil particles stripping down from soil, part of the particles spread out with slurry or water, other soil particles mixed with slurry under the jet impact force, centrifugal force and gravity force, re arrange regularly according to the size of a certain percentage of soil and quality. After the slurry solidified, forming a solidified body in soil, can improve the bearing capacity of the foundation, reduce the settlement, can also improve the effecf of supporting and anti-seepage. It is suitable for foundations of silt, cohesive soil, loess, sandy soil, artificial fill and crushed stone soil. PARFECT soil stabilization equipment can transfer the soil binder t

What is soil remediation

Contaminated soil remediation refers to physically, chemically and biologically transfer, absorb, degrade and transform pollutants in soil, which concentration can be reduced to acceptable levels, or turn toxic and harmful pollutants into harmless substances. Fundamentally, the technical principles for contaminated soil remediation may include: 1.Change the existing form or the mode of combining with the soil of pollutants in soil, reduce the mobility and bioavailability in the environment. 2.Reduce the concentration of harmful substances in the soil. The United States invested nearly $100 billion in contaminated soil restoration in 1990s. The theory and technology of contaminated soil remediation have become the frontiers of environmental science and technology research. The process of soil restoration is quite long, the need to solve the problem of soil pollution, it needs scientists of different disciplines, such as soil science, agronomy, ecology, biogeochemistry, marine scien

Traditional sludge disposal methods

图片
Most of the mud from the small ponds or river in the countryside is directly backfilled to farmlands nearby, which is the most common sludge disposal method used in rural areas in the past few decades. This sludge disposal method has many disadvantages: Some of the sludge has heavy metal pollution, or contains a lot of household waste and construction waste, and farmers refuse to accept it; After returning to the fields, it takes several years to dry. After airing, it needs second treatments. During this period, the fields can not be planted, and the government should pay farmers 1 ~ 2 years’ compensation fees in the form of rent. Cleaned out sludge of coastal rivers, lakes, ponds, and a considerable part of ithave been dumped at sea. In this way, the freight is expensive and tidal, and mud may be washed back inland. In Ningbo, China, the sludge being cleared will be dumped into sea which cost 176 RMB per cubic meter. The river silt in urban areas are often polluted, will usually
