Bottleneck analysis of petroleum contaminated soil remediation technology

The selection and treatment effects of petroleum contaminated soil remediationtechnology are closely related to the composition and properties and changes of petroleum pollutants in soil, and the soil environment. In the past 30 years, foreign study on bioremediation of petroleum contaminated soils showed rising trend, from the laboratory to the in situ remediation, from the isolation of degrading bacteria to the application of genetic engineering technology. In situ remediation technology is relatively simple, low cost, but there are environmental impact, time-consuming, slow and easy to make the proliferation of pollutants and other shortcomings. Ectopic remediation technology can improve the treatment efficiency by strengthening the degradation conditions, but need to transport the contaminated soil, and using a certain site and installation of ventilation equipment will increase the processing costs. The kind and residue of residual oil largely determine the technical difficulty, method selection, cost and duration of the remediation of petroleum contaminated soil.

PARFECT soil stabilization equipment can transfer the soil binder through the air compressor to the mixing head which is mounted on the excavator, and mix with the soil to improve the strength of the foundation.

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

图片
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
