Description
Technical field
The present invention relates to the processing methods of black and odorous water, and in particular to a kind of to choke water compound bio catalytic oxidation using multistage
The method and facility of emergency processing black and odorous water are arranged.
Background technique
In recent years, with China's Ecological Civilization Construction, sponge urban construction,《Water prevention and cure of pollution action plan》(ten, water)
Deepen continuously,《City black and odorous water renovation guide》" dirty, endogenous improvement is cut in control source；Running water circulation, clear water supply；
Purification of water quality, restoration of the ecosystem " comprehensive treatment scheme is gradually promoted.To carry out《Water prevention and cure of pollution action plan》, change
Kind urban ecological environment, people's governments at all levels accelerate city black and odorous water renovation.It is black for city inland river is effectively treated
Smelly water body, various physics, chemical, biological and combined sewage disposal technologies come into being.But due to city inland river
Intersection is often in city proper with river mainstream, vulnerable to the influence of city inland river rain flood, river flood position, can be used in
The land used of black foul sewage water process is very in short supply, and land used, electricity consumption, processing structures and supplementing facility equipment are vulnerable to flood inundation on tracks shadow
It rings, it is more difficult in two side of inland river or mainstream embankment construction conventional sewage treatment facility.It can therefore, it is necessary to provide one kind
Emergency and the method that black and odorous water can be effectively treated again.
Summary of the invention
Compound bio catalytic oxidation emergency processing is choked water using multistage the technical problem to be solved in the present invention is to provide a kind of
The method and facility of black and odorous water arrange that the black and odorous water in city inland river can be effectively treated in this method, improve urban ecology
Environment.
The method of the present invention for choking water compound bio catalytic oxidation emergency processing black and odorous water using multistage, including with
Lower step：
