Description
Technical field
The present invention relates to technical field of resource environments, combined sewage overflow of a kind of specifically city and rainfall runoff pollute device, method and the purposes of control.
Background technology
The water quality that water body is taken in the urban sewerage and drainage of city surface source pollution severe contamination, influence receiving water body aquatile, cause body eutrophication, destroy water landscape aesthetic feeling and potential threat human health.Under combined system draining system, it shows with the form of interflow water overflow; In segregation system, the form of discharging with rainfall runoff shows.
Its discharging and pollution course have following characteristics:
⑴ pollute influence and the domination that mainly is subjected to city hydrology cyclic process (be mainly rainfall and rainfall and form the runoff process), has randomness;
⑵ the scope that pollute is relevant with urban development situation (soil utilizes mode, the population density etc.) with the geology geographical conditions, and the time variation of pollution load and spatial variations amplitude are greatly;
⑶ the composition of pollutant is quite complicated, and the pollutant of mainly being paid close attention to is pathogen, aerobic substance, nutrients, noxious material, TSS, suspended particulate substance etc.
This overflow and pollute have randomness big, form that mechanism is fuzzy, latency is strong, lag behind and take place and the big characteristics of management control difficulty.
Be to solve the problem of combined drainage system overflow and city surface source pollution discharging, can adopt the measure such as dam, regulate and store that is provided with.
The method of damming is provided with interception ratio n exactly
00, surpassing drought stream flow even cut the disposal ability of the water passing capacity of dirty main pipe and the Wastewater Treatment Plant that is received, the combined sewage of the multiple of excess can be transferred and be handled.This is one of method that extensively adopts, and existing " Code for design of outdoor sewerage engineering " of China also adopts this method.
The rainwater storage pond is used for controlling one of effective measures of polluting with water drainage contradiction as nearly 20 years developed countries, also is suitable for comparatively extensive.It also can eliminate and reduce the obstruction of drainage pipe except cutting down the rainy day peak flow, improves and goes into Sewage Plant water quality (WEF/ASCE, 1992).
Traditional damming is that water passing capacity and sewage treatment capacity by improving main pipe realizes, realizes by storage capacity and regulate and store.
Summary of the invention
The objective of the invention is by traditional storage pond being carried out the change of configuration, Inlet and outlet water form and ancillary facility, realization storage capacity and the preprocessing function unification of regulating and storing, promptly single cover system realize device, method and the purposes of the lifting of the pondage of city combined sewage or rainfall runoff and interception ratio.
Combined sewage overflow of a kind of city and rainfall runoff pollute the method for control, and its step is as follows:
⑴ be arranged at city combined sewage overflow and rainfall runoff pollution control device underground, its surface coverage green plants;
⑵ rainfall is less, run-off more after a little while, combined sewage or rainfall runoff all enter the treatment pond of regulating and storing by water feed apparatus, precipitation promotes to transfer to treatment facility through the mud lifting appliance then and handles; Rainfall is big, but rainfall intensity is when little, and combined sewage or rainfall runoff enter the treatment pond of regulating and storing by water feed apparatus, transfers after preliminary treatment to sewage treatment facility and handles, and its pollutant of holding back transfers to the Treatment of Sludge facility with the form of mud and handles; Rainfall is big, when run-off is big, combined sewage or rainfall runoff enter the treatment pond of regulating and storing by water feed apparatus, part combined sewage or rainfall runoff transfer after by preliminary treatment to sewage treatment facility and handle, remainder is through discharging after by discharging device after the preliminary treatment, and the pollutant of holding back transfers to the Treatment of Sludge facility with the form of mud and handles.
Because of factors such as scale, lands used, can adopt many groups to be arranged in parallel and to move.
When being used for combined sewage, effective storage generally is provided with by design preliminary treatment amount 30min～180min; When being used for rainfall runoff, effective storage generally is provided with by design preliminary treatment amount 15min～120min.
