Integrated treatment process and equipment for river sediment dredging and residual water

Abstract

The invention belongs to the fields of environmental protection, water treatment technology and equipment, and in particular relates to an integrated treatment process and equipment for river dredging bottom sludge and residual water. The residual water of the dredged sediment is pumped into the sedimentation tank by the pump for preliminary sedimentation and separation. The residual water in the upper layer continues to flow to the stirring device through the lifting pump, and the flocculant, coagulant and residual water are fully mixed to form flocs. The remaining water further flows into the centrifugal device, and after rapid centrifugation, the flocs and remaining water are fully separated, and the separated remaining water is discharged. The rapid and integrated treatment equipment for dredged sediment and residual water proposed by the present invention is composed of dredged residual water inlet pump, sedimentation tank, sludge discharge pump, dosing device, stirring device, centrifugal device, water outlet pump and various pipelines. The whole set of equipment has simple process , not only found the optimal dosage and dosage ratio of flocculant and coagulant aid, but also the device has a high degree of integration, quick movement and easy operation. It is suitable for rapid treatment of residual water in large-scale dredging sites. Handling equipment.

AI Technical Summary

Benefits of technology

This patented method improves the efficiency at removing harmful materials from waters while reducing environmental impact. By introducing strong flocculating steps or combining different techniques like polymeric iron chlorides into the settling processes, these methods help stabilized heavy metals such as lead and radium out of solution without affecting their removal capabilities. Additionally, this new technique allows for efficient use of resources within small facilities. Overall, this innovative technical results improve wastewater purification systems' performance and provide better control over contamination levels.

Problems solved by technology

Technological Problem: Different methods such as mechanical or chemically treated resin rods with strong binding properties like cohesion force, hydrophobicity, and surface activity, may lead to poor removal efficiency when treating contaminating waters containing various types of solubilized matter. To address this issue, there was proposed combining both sewage and waste material disposals through biodegradable filtrations systems called activate membranemory coprecipitator polysulfonamides (APM). These agents help break down harmful components found in drained sediments while allowing effective cleanup without leaving behind any impurities.
