River channel water quality purification method

Abstract

The invention relates to a riverway water quality purification method. A riverway water quality purification slow-release structure is constructed; stacking gabion boxes on the rammed earth layer; thelower portion of the gabion box is filled with stone to form a stone layer, the water quality purification slow-release agent is packaged through a fiber non-woven fabric plastic package bag and thenfills the remaining space of the gabion box, then the opening is locked and sealed through a spiral iron wire, and the fiber non-woven fabric plastic package bag is replaced regularly. The slow-release agent is sealed and filled into the gabion box, so that the river bank slope can be reinforced and protected, and meanwhile, river water purification in the flood discharge period can be implemented in advance; the continuity and persistence of the purification effect are guaranteed, the water quality purification effect on the river in the flood discharge period is achieved, the engineering difficulty and manpower and material resources are greatly reduced, the influence on the surrounding environment is low, and the positive ecological environment effect is achieved.

Description

technical field [0001] The invention relates to the field of ecological management, in particular to a method for purifying river water. Background technique [0002] During the flood discharge period, rivers often have hydrological characteristics such as rapid water flow, rising water level, and increased flow. In urban areas, rivers play an important role in the safety of flood discharge in cities and are the main flood discharge channels for cities. However, at the same time, Domestic garbage, domestic sewage, industrial wastewater, etc. in the city will also enter the river along with the flowing water, causing the water quality of the river to deteriorate and be polluted during the flooding period, affecting the water environment of the river and the surrounding human life. [0003] At present, there are mainly physical methods, chemical methods and biological methods for river water pollution control, such as water diversion, sediment dredging, chemical algae removal,...
