Sludge treatment in trenches is imperative, and DS mobile washing and restoration station is here to help!
The pipeline sediment removed during pipeline maintenance and dredging is also called trench sludge. Its source is the particles and impurities that enter the drainage pipe system from domestic sewage and industrial wastewater, as well as large particles that enter the drainage pipe network. Garbage
The pipeline sediment removed during pipeline maintenance and dredging is also called trench sludge. Its source is the particles and impurities that enter the drainage pipe system from domestic sewage and industrial wastewater, as well as large particles that enter the drainage pipe network. Garbage, construction waste, construction site mud, etc. are produced at many points, in a wide area, scattered, irregular and in small quantities.
Since the sources of sewage sludge are complex, and the composition fluctuates greatly depending on the city, land type and pipeline type, it is necessary to improve the understanding of the properties of sewage sludge in order to provide appropriate technical paths and treatment methods for its treatment and disposal. plan.
There are also great differences in the properties of trench sludge in different pipe network types. The sewage sludge in the diversion sewage pipe network contains a lot of inorganic substances such as mud, sand, and stone. The sewage sludge in the sewage pipe network or the combined pipe network often contains a higher proportion of organic matter and even domestic garbage. The sludge may have a higher moisture content, COD and odor concentration than the combined sludge.
Different land use types will also affect the properties of trench sludge. The sludge near urban main roads usually contains more sand and gravel, while the sludge in residential areas usually has higher organic matter content and more domestic waste. In commercial areas with intensive catering, the sludge contains high organic matter content, which requires higher requirements for gravel cleaning and organic matter removal.
When trench sludge overflows in pipelines, it will cause pollution to the receiving water body. Therefore, the type and concentration of pollutants contained should also be paid attention to. In addition to the content of carbon, nitrogen, phosphorus and other pollutants, the content of heavy metals in trench sludge cannot be ignored. In addition to the possible environmental pollution caused by heavy metals, there are often strict requirements on the heavy metal content in trench sludge treatment products or resource utilization products. The heavy metal content in trench sludge is also closely related to the type of pipe network. The heavy metal content in the channel sludge of the combined pipe network or the pipe network in residential areas and industrial areas is relatively high. To be more precise, it is closely related to human activities.
In recent years, the country has intensively promulgated a number of policies and regulations related to the treatment and disposal of urban sludge and solid waste, the core of which is to achieve the reduction, resource utilization and harmlessness of sludge. Ditch sludge has low organic matter content, high ash content, low calorific value, and unstable nutrient content. It is not suitable for agricultural use, soil improvement, landscaping, and incineration. It can be used as building materials after certain treatment. Therefore, appropriate treatment is required before final disposal of trench sludge.
Desen Environment recommends a high-efficiency trench sludge treatment equipment called a mobile washing repair vehicle. It is a soil washing equipment that integrates many advantages. It has outstanding advantages such as flexible transition, quick installation, low consumption and high efficiency, and small size. The mobile modular design is not subject to geographical restrictions and is suitable for operations in a variety of situations. The equipment can enter and exit freely and flexibly; the integrated design and integrated multi-stage screening unit combination enable rapid installation of equipment and save a lot of time and cost; integrated multi-stage The combination of screening units saves project material transportation and labor costs, and the overall system operates efficiently; the equipment layout is compact, and the integrated design PLC overall module intelligent control system is suitable for various construction conditions.
