A screening method for the application of sediment remediation technology

Abstract

The invention discloses a screening method for sediment remediation technology application. According to the invention, integrated analysis and parsing are carried out on years of data of lakes, oceans, rivers, reservoirs and the like to formulate key parameters required by sediment remediation technology screening, with the data including total nitrogen, total phosphorus and organic matters, active phosphorus, active nitrogen, phosphorus adsorption parameters, an electron transfer system, nitrogen and phosphorus release rates and the like; according to the method, before a sediment remediation technology application scheme is formulated, the pollutant distribution situation, the pollutant main form, the pollutant release potential and capacity and the like of the sediment can be fully known, meanwhile, the relevance between each index and the sediment pollution degree and the remediation technology are quantified, and accordingly a set of sediment remediation technology selection method is constructed. The method is simple, reliable and strong in practicability, improves the accuracy and scientificity of sediment remediation technology selection, and is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of sediment restoration, in particular to a screening method for the application of sediment restoration technology. Background technique [0002] There are many types of sediment remediation technologies for lakes, oceans, rivers, reservoirs and other water bodies, and each remediation technology has advantages, disadvantages and scope of application. Sediment remediation technologies mainly include environmental protection dredging, oxidation, passivation, masking and biology, etc. At present, environmental protection dredging technology is widely used. However, environmental protection dredging technology is not suitable for any type of polluted sediment remediation, and the cost of environmental protection dredging Expensive, environmentally friendly treatment and storage of dredged sediment has seriously affected the application effect of this technology. Generally, environmental protection dredging te...

Problems solved by technology

[0003] However, there is no uniform quantitative standard or method for the selection of the above-mentioned technical applications, and it relies more on subjective judgments. Therefore, it is urgent to establish a set of quantitative methods for the screening of sediment restoration technologies. Restoration technology of sediment characteristics, which is of great significance to planners, designers and managers of sediment restoration
