A Black and Odor River Treatment Method Based on Target Contribution Degree

Abstract

A treatment method for black and odorous rivers based on target contribution, the treatment method includes the following steps: (1) Collecting water samples: collecting sediment and water samples from black and odorous rivers and placing them in a reactor, and calculating the pollution to be reduced Load; (2) Simulation experiment: set different levels of flocculant and microbial dosage, aeration mode, plant and biological filler types in the reactor to set up parallel experiments, and select the best combination according to the changes in the water quality indicators in the reactor (3) Determine the contribution of different treatment technologies: combine the best plans in one reactor and use the water quality index at this time as a comparison, remove one of the treatment technologies in each experiment, and compare with the control technology To compare the water quality indicators, the ratio of the difference between the two water quality indicators and the control is the contribution of the treatment technology, and the contribution and input cost of each treatment technology are calculated. The ratio of the two is the cost performance of the technology.

Description

technical field [0001] The invention relates to the technical field of river course management, in particular to a black and odorous river course treatment method based on a target contribution degree. Background technique [0002] With the rapid development of industrialization and urbanization in our country, especially the rapid growth of the national economy for many years, the output of domestic sewage and industrial wastewater is increasing day by day. The influx of a large number of pollutants leads to serious eutrophication of urban water bodies, resulting in a sharp consumption of dissolved oxygen in water bodies, resulting in long-term anoxic water bodies that appear black and odorous, and the ecological balance of water bodies is seriously damaged. Black and odorous urban water bodies such as rivers have become a common phenomenon in my country's cities, and this phenomenon has seriously affected the life of residents along the water body and the image of the city...

Problems solved by technology

[0005] At present, there is no one river course treatment plan that can be applied to all river courses, because the pollution situation of each river course is different, and the treatment costs of different treatment methods are different, and the treatment effects are also different, with their own advantages. This is also a major difficulty in current river management
