Abstract

The invention belongs to the technical field of water treatment, and particularly relates to a black and odorous water bottom mud passivation system. The system comprises a feed pipe, a pipe mixer, a reactor and a discharge pipe which are sequentially communicated, the pipe mixer is provided with a feeding pipeline for supplying first multifunctional nano-composite materials, the feeding pipeline is provided with a water supply pipeline, a stirrer is arranged in the reactor, a bottom mud layer is arranged at the bottom of the reactor and internally filled with second multifunctional nano-composite materials, the first multifunctional nano-composite materials include 10-20 parts of COD (chemical oxygen demand) removing materials and 80-90 parts of heavy metal removing materials, and the second multifunctional nano-composite materials include 10-20 parts of COD (chemical oxygen demand) removing materials and 80-90 parts of heavy metal removing materials. The black and odorous water bottom mud passivation system is mainly used for performing heterotopic reinforcement treatment for endogenous pollutants in black and odorous water treatment and performing in-situ passivation for the pollutants, passivated bottom mud can serve as fertilizers to be applied, and economic benefits are generated.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a sediment passivation system for black and odorous water bodies. Background technique [0002] In recent years, with the rapid development of my country's urbanization and industrialization process, some urban water bodies, especially small and medium-sized urban water bodies, have directly become industrial, agricultural and domestic sewage due to the lag of water pollution control and treatment measures, or limited capacity or low level. The main discharge channels and places of the city lead to large-scale pollution of urban water bodies, causing eutrophication of water bodies, and eventually forming black and odorous water bodies, which have serious adverse effects on urban ecological and cultural landscapes, and have attracted more and more attention. [0003] Currently, the treatment and restoration technologies for black and odorous water bodies mainly ...
