And its operation method.
Background technique
Currently, the initial rainwater pollution of the pollution load of overflow and separate system of combined flow system is to cause urban water-body environmental degradation
Major influence factors, it is therefore desirable to water body is emitted into after handling initial rainwater again, due to initial rainwater have the time
Short, such as processing unit directly is arranged in draining end in the big feature of flow, then the scale of processing unit will be very big, often at present
The solution of rule is that storage pond is arranged in drainage system end, stores initial rainwater at rainfall initial stage, then with mentioning
It rises pump to be uniformly delivered to the initial rainwater stored in storage pond in processing unit, water body is emitted into after processing, though this kind of scheme
It so can reduce the scale of processing unit, but since storage pond and processing unit is respectively set, investment is high, takes up a large area, and
The limitation of processing unit processing capacity, often storage pond emptying time is longer, comes temporarily to next rainfall, storage pond is not put also
Sky has seriously affected the service efficiency of storage pond.
Meanwhile it is higher and higher with requiring water environment this year, the processing to initial rainwater is no longer simple removal SS,
TP and a small amount of organic matter more focus on the nutriments such as removal ammonia nitrogen, and accordingly, treatment process cannot be using simple mixed
Solidifying depositing technology, need to use biological treatment.And conventional activated sludge process is used, initial rainwater intermitten service can not be adapted to
Requirement be unable to maintain that microbial activity, and since the microorganism in activated sludge process is outstanding when there is no initial rainwater in dry season
