The remediation system includes soil pretreatment system, medicament mixing system and seepage control system. 1.Pretreatment system. Crushing, screening or adding soil amendments to the excavated contaminated soil. The system equipment includes crushing screen, bucket, excavator, bulldozer and so on. Pretreatment system 2.Medicament mixing system. The medicament mixing system of contaminated soil and chemicals can be divided into two types according to the mixing methods of the equipment: Adopt internal mixing equipment, that is, inner mixing cavity, mixing contaminated soil and chemicals evenly in the equipment; Adopt external mixing equipment, that is, excavator mixing head, which need to set up reaction pool or reaction field, contaminated soil and chemicals are evenly mixed in a reactor or reaction chamber by mixing equipment. The system equipment includes walking type soil conditioner, shallow soil mixer and so on. Medicament mixing system 3.The impervious system is ...

The soil is originally a natural shelter and purification site for various wastes, and the soil receiving pollutants did not mean that the soil was contaminated. Only when all kinds of pollutants in the soil are too much, exceeding the self purification capacity of the soil, and thus harmful effects on hygiene and epidemiology, indicate that the soil has been polluted. There are many reasons for soil pollution, such as industrial sludge, garbage, agriculture, sewage irrigation, settlement of pollutants in the atmosphere, heavy use of mineral fertilizers and pesticides containing heavy metals and so on. China existing cultivated land has nearly 1/5 pollution of varying degrees. Pollution of soil will lead to crop reduction, and may even cause excessive pollutants in the agricultural products, thus endangering human health. In addition, with the acceleration of economic development and urbanization, site pollution caused by industrial and mining enterprises is also very serious. As the i...

The reclamation area provide a broader space for the future development of the city. The successful coastal reclamation experience of Zhenhai District fly ash emissions of Beilun power plant of can be used for reference. It is understood that the Zhenhai District has already been reclaimed 60 thousand acres coastal area, of which more than 30 thousand acres have been used as industrial land to Zhenhai District government recycling. Through reclamation, not only the pollution of fly ash has been solved, but also good ecological benefits and good economic benefits have been obtained. The reclaimed shoal as treatment site for construction waste and river silt, blow up the mud and mud ashore, after technical treatment in the short term can form large tracts of land, so as to save a lot of land costs, and reduce the pollution of water environment. PARFECT soil stabilization equipment can transfer the soil binder through the air compressor to the mixing head which is mounted on the excavat...

1.It is reasonable that the polluters pay for it. However it is not easy to find the polluters, some factories and mines have been closed down after many restructuring, and these polluted area can only rely on the government. Local governments have become helpless polluters, but there is no financial soil remediation funds, and many abandoned lands have been asleep for a long time. The pattern that the polluters pay for soil remediation is quite few. 2.It is also possible for beneficiaries to pay for the soil remediation. Through the soil stabilization projects , the land users has benefited, and they should pay for it. This is mainly for the remediation of the those borderlands, but the government could not afford the payment, and we can only find land users to pay for it, while real estate company is the main object. This pattern that beneficiary pay for the soil remediation is also quite few because it is not directly involved by the government. 3.The government pays for soil rem...

The material of soil binder is the dominant factor affecting soil stabilization effect, it is divided into solidified material and stabilized material. Solidified materials are mainly cement and fly ash (blast furnace slag and fly ash) gel material. Blast furnace slag and fly ash must be caused by evocating agent such as cement and lime to produce hydration condensation.The combination of initiator and gel material mainly has: cement + fly ash cement, cement + blast furnace slag, cement + kiln ash; lime + fly ash, lime + blast furnace slag, lime + kiln dust; cement + lime + fly ash, cement + lime + blast furnace slag, cement + lime + kiln ash. Contaminated by heavy metal such as lead, zinc, cadmium, copper and other heavy metals cation or cationic composite in soil and sediment, can be directly used gel material for solidification, the general effect is very good, you can also add clay or zeolite to enhance. Soil contaminated by arsenic and mercury and sediment solidification are ...

How big is the market for soil remediation ? The market is divided into three categories: the first is agricultural land, which is said to have 390 million acres to be remediated; the second is the site of the abandoned or relocated factories; the third is abandoned mines and oil wells. Some experts believe that the country’s remediated arable land market of nearly 4 million (there are scholars think that 10 trillion), and the market of the factory and mine can be remediated is also more than 600 billion. Such a large market capacity, there must be a lot of profit margins, the key is the profit model. In order to earn money on contaminated soil remediation , there are generally two kinds of ways, one is to earn wages, like BT, BOT, EPC project. Whether the government or social capital to pay, the remediation construction itself is profitable, it also includes elements of capital, equipment and technology profit. Another is to earn land fee, and this is big, soil restoration is equiva...

Powder jet pile method, with special equipment, the reinforcing binder powder materials (cement or lime) through transmission of compressed air, and mix with soil, to produce physical and chemical reactions after full forming a certain strength pile. This method is a kind of soft soil foundation reinforcement method for improving soil quality and foundation strength. It can be widely applied to foundation reinforcement such as soft soil, sludge, miscellaneous fill and soft clay. Powder jet pile is a deep mixing method in soft foundation treatment, which is using compressed air to transport lime and cement and other powder material in soft soil, in situ mixing, compaction, exchange, coagulation. Through a series of physical and chemical functions, such as ion exchange, agglomeration and chemical interaction between reinforcing material and soft soil, forms a column reinforced soil with integrity, water stability and a certain strength, and make up a composite foundation with in-situ so...
