Abstract

The invention relates to the technical field of environmental remediation, in particular to a bottom mud repairing agent for a mud-water interface aerobic layer of polluted bottom mud as well as preparation and application thereof. The bottom mud repairing agent comprises a microbial agent, a biological growth promoting agent, a biochemical reaction electron acceptor, a counterweight agent, a binder and an adsorbent, the raw materials are finally prepared into a preparation A and a preparation B, and then the two repairing agent preparations are mixed to obtain the bottom mud repairing agent. Through a direct sowing mode and an aerobic layer covering the surface of the bottom mud SWI, mineralized organic pollutants are effectively degraded, the oxidation-reduction potential of a mud-water interface is rapidly improved, ammonia nitrogen and total phosphorus are inhibited from being released to an overlying water body, the thickness of the bottom mud SWI aerobic layer is improved, dissolved oxygen can be continuously provided for life activities of microorganisms, the thickness of the bottom mud is reduced, the micro-ecological environment of the polluted bottom mud is improved, the lasting self-cleaning capability of the polluted bottom mud is enhanced, and the water quality is kept.

Description

technical field [0001] The invention relates to the technical field of environmental restoration, in particular to a bottom mud restoration agent for an aerobic layer at the mud-water interface of polluted bottom mud and its preparation and application. Background technique [0002] Sediment is an important endogenous pollution of the river. It continuously releases pollutants into the water body, causing water quality to deteriorate. Under anaerobic conditions, denitrification and methanation of the sediment produce a large amount of gas, which directly causes the sediment to float up, and the water body is black and smelly. Therefore, the sediment Restoration is an important part of the ecological restoration of urban rivers and lakes, especially in urban river regulation, after dredging, sewage interception, bank revetment and other engineering measures are completed, sediment restoration is an important part of fundamentally solving river and lake pollution and rapidly im...
