Soil washing equipment is a soil remediation technology equipment that uses water or other solvents to transfer pollutants in the soil from the solid phase to the liquid phase. It has the advantages of fast, efficient, and economical, and is suitable for treating various types of heavy metals, organic matter, etc. pollutants. Combined with the status quo of soil remediation in China, the application and development of soil washing equipment are analyzed as follows:
The application demand of soil washing equipment will continue to grow
According to the "National Soil Pollution Survey Bulletin", the overall survey site exceeding the standard rate in my country is 16.1%, among which the soil pollution problem of industrial and mining sites is prominent, and the point exceeding standard rate reaches 36.3%. The "14th Five-Year Plan for the Protection of Soil, Groundwater and Rural Ecological Environment" proposes that by 2025, the overall quality of the national soil and groundwater environment will remain stable, and the safe use of polluted farmland and key construction land will be consolidated and improved. In order to achieve this goal, it is necessary to increase the restoration of contaminated sites. As a mature, efficient and economical restoration technology, soil washing equipment will play an important role in the restoration of industrial contaminated sites, and the application demand will continue to grow.
The technical innovation of soil washing equipment will continue to deepen
With the continuous expansion of my country's soil remediation market and the intensification of competition, the technological innovation of soil washing equipment will become a key factor to enhance the core competitiveness and market share of enterprises. Technological innovation mainly includes the following aspects: first, optimize the selection and proportion of washing agents, improve washing efficiency and reduce washing costs; second, improve rinsing methods and processes to adapt to different types and degrees of polluted sites; The third is to improve the recovery and reuse of eluent, or to recycle the pollutants in the eluent to reduce the impact on the environment; the fourth is to develop more low-carbon, intelligent, and efficient washing equipment to improve equipment performance , reduce equipment energy consumption.
The application specification of soil washing equipment will be further improved
In order to standardize and guide the management, control and restoration of soil pollution risks in construction lands, my country has issued a series of management policies and technical guidance documents, such as the Measures for the Administration of Credit Records of Employers and Individuals in the Construction Land Soil Pollution Risk Control and Restoration (Trial) ", "Construction Land Soil Pollution Risk Control and Restoration Directory and Guidelines for Disclosure of Information Related to Restoration Construction", etc. These documents put forward certain requirements and specifications for the application of soil washing equipment in the restoration of construction land, such as the qualification certification of practitioners and individuals, credit record management, and information disclosure. With the continuous development of my country's soil remediation industry, these documents will be further improved and refined to provide clearer guidance and guarantee for the application of soil washing equipment in construction land remediation.
To sum up, soil washing equipment is a soil remediation technology with broad development prospects. With the continuous expansion of my country's soil remediation market and the continuous deepening of technological innovation, the application demand for soil washing equipment will continue to grow, and the technical level It will continue to improve, and the application specification will be further improved.
