Description
Technical field
The invention belongs to technical field of sewage, relate to a kind of black smelly water tackling method.
Background technology
The landscape water bodies such as river are ingredients important in human settlement environment in city, but owing to its easily pollution, water environment are held
Measure the features such as little, water body self-purification ability is poor, it is easy to become the receptor of resident living sewage, rainwater and rubbish, thus cause
A large amount of consumption of Dissolved Oxygen in Water, cause water hypoxia and the most smelly state, make whole ecosystem crisis occur.River, city
Flow out existing black smelly, it has also become the pollution problem that the big or middle city of China's many exists jointly, the network of waterways, Hei Choushi China city, river
One universal phenomenon, has a strong impact on resident living, city image and ecological environment.
During many institutes weeks, the black smelly mainly excess of city river is received dirt and is caused oxygen supply of water body and the unbalance result of oxygen consumption, water body
Under anoxia or even anaerobic condition, pollutant convert and produce odorant and ferrum, the manganese such as ammonia nitrogen, hydrogen sulfide, VFA
The atraments such as sulfide.Sanitary sewage is to cause the black the most universal and topmost smelly polluter of city river.Other pollute
Source also has: house refuse, organic industrial sewage, combined system pipe network overflow sewage, Sewage Plant tail water, livestock and poultry farm fecal sewage
Deng.Eliminate city river black smelly, improve urban water environmental quality, to ensureing city people's health in residential environment, promoting social harmony with economical
Sustainable development has extremely important realistic meaning.
And existing processing method is usually Physical, chemical method and bioanalysis, but Physical cost of investment is high, takes effect
Slowly, it is high to there is use cost in chemistry rule, and the problem easily causing secondary pollution of water, biological method is in river black-odor control
Application quite varied, mainly have artificial wetland treatment, hydrophyte restoration, a biological restoration etc., but bioanalysis existence process
Slow-footed problem.
