Problems solved by technology

This not only delays the construction period, but also causes huge waste to the effective use of manpower and machinery of the project.
In the two major deep-Hong Kong projects in the Bohai Sea currently under construction in my country, the land-making projects in Shanghai and Zhejiang, the Shenzhen-Hong Kong projects in Guangdong and Fujian, the dredging and remediation projects of the Yellow River, Yangtze River, Pearl River, Haihe, and inland lakes, high-concentration sediment water The emission problem of the project has brought huge troubles to the investment and construction period of the project

Abstract

The invention discloses a making method of mud coagulation agent, which comprises the following steps: allocating each component with 0.025-0.100% ferric polysilicate, 0.025-0.100% polyacrylamide and 0.025-0.100%Na2CO3; making solutions; adding each solution into mud sequently; stirring to form turbulence; blending to separate from mud turbulence under flow turbulence condition for 0.5 min.

Description

technical field [0001] The invention relates to a sediment coagulation agent and a sediment coagulation separation method capable of rapidly aggregating, settling and separating high-concentration suspended fine silt particles in the field of river, sea and lake sediment engineering. Background technique [0002] The muddy coast formed by the many rivers flowing into the sea in my country is an important part of the mainland coast of China, with a length of more than 4,000 kilometers, accounting for about 22% of the coast of the mainland of my country. This makes it inevitable to deal with silty sea mud in the economic construction of the country's coastal areas, such as land reclamation, marine engineering bridges, and seaport construction. Among them, the problem of dealing with high-concentration sediment is often one of the bottlenecks affecting project investment, project progress, project quality, and environmental protection. [0003] The rivers and lakes in our coun...
