Embodiment 1

[0028] A method for urban combined sewage overflow and rainwater runoff pollution control, the steps are as follows:

[0029] ⑴ Set the pollution control device for urban combined sewage overflow and rainwater runoff underground, and its surface is covered with green plants;

[0030] ⑵When the rainfall is small and the runoff is small, all the combined sewage or rainwater runoff enters the storage tank through the water inlet device, settles, and then is lifted by the sludge lifting device and transferred to the treatment facility for treatment; the rainfall is large, but the rainfall intensity is not When it is large, the combined sewage or rainwater runoff enters the regulation and storage treatment pool through the water inlet device, and is transferred to the sewage treatment facility for treatment after pretreatment, and the intercepted pollutants are transferred to the sludge treatment facility for treatment in the form of sludge; When the runoff is large and the runoff ...

Abstract

The invention discloses a device and a method for controlling urban combined sewerage overflow and rainwater runoff pollution and application thereof, and the device comprises a storage adjusting treatment pool (1), a water inlet device (2), a storage adjusting water outlet device (3), a pretreatment water outlet device (4) and a sludge lifting device (5), wherein the water inlet device (2) and the storage adjusting water outlet device (3) are communicated with the storage adjusting treatment pool (1) through a water inlet pipe channel (11) and a storage adjusting water outlet pipe (13) respectively; the inlet of the pretreatment water outlet device (4) is communicated with a water outlet weir (9) of the storage adjusting treatment pool (1); the top end of the sludge lifting device (5) is positioned at the mouth of an overhauling well (8) of the storage adjusting pretreatment pool (1); and the lower end of the sludge lifting device (5) is positioned in a slurry bucket (7) of the storage adjusting treatment pool (1). The invention has the advantages that the promotion of storage adjusting capacity and interception ratio of the urban combined sewerage or rainwater runoff are realized by a single set of system; and compared with the traditional storage adjusting pool, the manufacturing cost is increased by only 10%-30%, and the pollutant interception capacity with the intercepting multiple of n0 equal to 1-3 is increased correspondingly, namely the pollutant interception capacity is increased by more than 50%-100% generally.

Description

technical field [0001] The invention relates to the technical field of resources and environment, in particular to a device, method and application for urban confluence sewage overflow and rainwater runoff pollution control. Background technique [0002] Urban non-point source pollution seriously pollutes the water quality of urban drainage receiving water bodies, affects aquatic organisms in receiving water bodies, causes eutrophication of water bodies, destroys the beauty of water body landscapes, and potentially threatens human health. Under the combined drainage system, it manifests itself in the form of combined water overflow; in the divergent system, it manifests itself in the form of rainwater runoff discharge. [0003] Its discharge and pollution process has the following characteristics: [0004] (1) Pollution is mainly affected and dominated by the urban hydrological cycle process (mainly rainfall and the runoff process formed by rainfall), and its occurrence is ...
