Silt, a long-neglected environmental problem, has become increasingly prominent with the acceleration of urbanization in China. Whether the sludge is polluted or not and the types of pollutants it contains are different, and the corresponding treatment methods are also different. When choosing a sludge treatment technology, we also need to consider the use after treatment, which involves the selection and application of sludge treatment technology.
First of all, we need to be clear that the choice of sludge treatment technology is determined based on the nature of the sludge and the degree of contamination. For example, for sludge with high nitrogen and phosphorus nutrient content, if the treated sludge is intended to be used as an embankment or ordinary fill, and it is far away from the water source, then nitrogen and phosphorus cannot re-enter the water source to cause pollution, and the pollution of nitrogen and phosphorus is generally no longer considered. This is because, in this case, the nitrogen and phosphorus pollution has been effectively controlled, and it is redundant to treat it again.
Secondly, the treatment of sludge should also follow the principles of reduction, harmlessness and resource utilization of solid waste treatment. This means that we should use the silt as much as possible. However, when the sludge contains some special pollutants such as heavy metals or some polymer refractory organic pollutants that cannot be removed, resource utilization will cause secondary pollution. In this case, we need to dispose of it in one step, that is, take measures to reduce its biological toxicity and use it safely.
In this case, the advanced JWC-DWS dredging and sludge dewatering harmless treatment system is particularly important. This high-tech equipment system is specially designed to solve the sludge problem and has advanced slurry separation technology. With this system, the salvaged sludge can be treated quickly and efficiently, so that the water in the sludge can be fully removed, thus greatly reducing the risk of contamination during the treatment process.
The application of JWC-DWS dredging and sludge dewatering harmless treatment system can not only realize the cleanliness of rivers, lakes and other waters, but also carry out dewatering treatment on the cleaned sludge, so as to achieve the purpose of harmlessness and recycling. Let's take a closer look at the benefits and application scenarios of this system.
In terms of sludge dewatering, the JWC-DWS system has significant advantages. Through the use of high-pressure jet technology, the water in the sludge is quickly removed, so that the sludge reaches the highest degree. On this basis, the dewatered sludge is harmlessly treated to eliminate its harm to the environment and human body. At the same time, the dewatered sludge has a high resource utilization value. It can be used to make building materials, backfill, etc., to realize resource recycling and reduce the cost of environmental pollution control.
In general, the selection and application of sludge treatment technology need to comprehensively consider the nature of sludge, the degree of pollution, the use of the treated sludge and other factors. Only in this way can we ensure the effect of sludge treatment, avoid secondary pollution, and realize the rational use of resources. This is of great significance to China's current environmental protection work, and it is also an inevitable choice for us to practice the concept of green development.
