Water ecological restoration method of black and odorous river containing high ammonia nitrogen

Abstract

The invention discloses a water ecological restoration method of a black and odorous river containing high ammonia nitrogen. The water ecological restoration method comprises the following specific steps: a, constructing an aeration system; b, erecting a submerged plant growth bed; c, equipping a cage culture type benthos net cage. According to the water ecological restoration method of the blackand odorous river containing the high ammonia nitrogen, disclosed by the invention, by adopting a microorganism-plant-aquatic animal combined restoration method, the self-cleaning ability of the blackand odorous river can be strengthened, the effluent quality of the black and odorous river can be increased, and an ecological effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of river management, in particular to a water ecological restoration method for high-ammonia-nitrogen black-smelly river courses. Background technique [0002] Landscape water bodies such as lakes and rivers in cities are an important part of urban human settlements, but they can easily become sinks for residents' domestic sewage, rainwater and garbage, resulting in a large consumption of dissolved oxygen in the water body, resulting in the lack of oxygen in the water body and turning it black. Odor state, in which nitrogen pollutants are one of the main odor-causing substances. Domestic sewage is the most common and main source of pollution that causes black and odorous urban rivers. Other sources of pollution include: domestic garbage, organic industrial wastewater, overflow sewage from combined pipe networks, tail water from sewage plants, fecal sewage from livestock and poultry farms, etc. Eliminating ...
