Problems solved by technology

The current cleaning method mainly uses dredge pumps to transfer and stack the sediment. However, due to the large enrichment of microorganisms and harmful elements in the sediment, simple stacking is likely to cause secondary pollution of the dumping site. Therefore, the treatment of the extracted material becomes especially critical
Conventional sterilization and adsorption treatment are out of touch with the extraction process, so it is easy to cause problems of long treatment cycle and high treatment cost

Abstract

The invention relates to a sediment treatment device for an urban river water conservancy project, which comprises a crushing chamber, a separation chamber, a sewage treatment device, a sediment storage box and a primary sundries storage box. Primary filter is carried out in the separation process, so that harmful microorganisms and harmful elements, which are transferred from sediment to water are filtered out primarily; by a specific separation mode, sundries, silt and water can be separated efficiently; and by specific arrangement of the sewage treatment device, specific water can be treated in an efficient, rapid and inexpensive way.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and in particular relates to a sediment treatment device for urban river water conservancy engineering. Background technique [0002] As a very important factor for the existence and development of urban economic, social, and humanistic systems, the water environment of urban rivers has ecological functions such as providing people with green space, water sources, protecting the surrounding environment, and developing tourism. The pollution of urban rivers has its unique characteristics, in which silt and sand coexist, and a large number of microorganisms are enriched in the silt, and the long-term existence of such microorganisms will cause irreversible biological pollution to the water body of urban rivers, and in the silt will Accumulate harmful elements such as heavy metals in the water body, so it is necessary to periodically clean up the sediment (silt and sand) at the bottom of...
