Abstract

The present invention relates to river purifying system and river waterworks. The city river is divided into rain water course and sewage course, the lower layer course is for sewage and initial rain water, and the upper layer course is for rain water as the water source for waterworks.

Description

River purifying system and river waterworks thereof

The present invention relates to the sewerage treatment of biological pipe well, waters Wastewater Treatment Plant and pollution treatment industry and patented technologies such as urban sewage treatment and waste gas purification thereof, especially urban waters construction are with the river purifying system and the river waterworks thereof of dirty pollution treatment and comprehensive anti-pollution.

Urban river is the natural channel of urban sewerage and drainage, but the dirty shunting of the rain of existing urban sewerage and drainage, go into the river by municipal sewage on the one hand, and be pumped to land Wastewater Treatment Plant with the urban pipe network long distance and purify draining, thereby expend pipe network duration, construction and operating costs in a large number, so that be difficult to effect a radical cure river pollution for a long time; And on the other hand, because the dirty flow of Chang Yuyu is much larger than the dirty flow of drought, its urban pipe network overflows, and rain sewage is enough to the black smelly a few days of direct polluted river water at the beginning of one of the inflow stream.

The purpose of this invention is to provide a kind of river purifying system and river waterworks thereof, and in the dirty shunting of rain, the shunting just of enforcement rain purifies draining with the waters of river waterworks.

The object of the present invention is achieved like this: in city river, the blowdown of effluent stream, shunting water factory, segmentation sluice are purified waste water with interflow water factory and are connected, the lower floor that it is characterized in that double-deck river course is the Xia Shui river course of dry flow sewage and first rain sewage afflux, and the upper strata is the last water river course that upstream dry flow sewage shunting water factory purifies draining or back rain clear water afflux.Simultaneously, shunting water factory is set in the upper river; And make the purification draining of upstream flow purified water source as the river course drought, then the rain clear water then is a river course rain stream natural water source.The segmentation sluice is set in the water river course on the place, and makes purification draining or back rain clear water, all have the waters landscape function of enough river water levels.And interflow water factory is set in the downstream river course of place, and has the waters industry function that waste gas promotes the waters comprehensive purifying of waste water delivery waste residue and reclaims the pollution treatment resource comprehensively.Therefore, in the Xia Shui river course, river waterworks is set, and has the waters value-added functionality of the platform real estate and the investment river purifying system of the compound building foundation of urban waters.In addition, in the river, place or riverbank down or on the river course, pipe well is collaborated in the combined sewage input of effluent stream blowdown, and is connected with aerobic pipe well recirculation water with the denitrogenation of anoxic pipe well; And the shunting pipe well is set, aerobic pipe well is connected with shunting pipe well one end water, the other end of shunting pipe well then purifies drainage water diffluence water with dephosphorization and is connected.And biological pipe well and pipe well air pump are set in the river waterworks of place, and, be the gas water lift power of river waterworks for utilizing burnt gas and the nitrogenous lonely anaerobism stirring and the aerobic aeration of input air.The purification draining of its river waterworks is connected with purification waters water up to standard.Then the rain clear water is connected with edible water area resource water.

Owing to adopt such scheme, need not the long distance urban pipe network, huge sewage pumping station and land thereof purify water factory, the dirty shunting of the rain of its urban sewerage and drainage, rain shunting just and waste gas promote waste water delivery waste residue, need not long distance transport, the landfill soil, burning facility and the waters comprehensive anti-pollution of eliminating secondary pollution, by river diversion, layering and segmentation purify draining, its urban river purification duration is significantly shortened, construction and operating costs reduce in a large number, and clear radical cure city rivers pollution and riverbed mud thereof, the liquid state classification of household garbage and burnt gas is given and being handled and the biochemical processing synchronously of combined sewage, and, reclaim the three wastes (water comprehensively, slag, the valley environment benefit and the value-added economic benefit of sustainable development industry of pollution treatment resource gas) and investment river purifying system.

The present invention is further described below in conjunction with drawings and Examples.

In accompanying drawing 1:

Dry flow sewage (1) input Xia Shui river course (2), the upstream dry flow sewage is promptly imported shunting water factory (3), when fine day, purify water river course (5) in draining (4) input, up to the interflow water factory (7) in downstream shunting sluice (6) backflow Xia Shui river course, the purification draining of its combined sewage conveying up to standard purifies waters (30); Rain stream draining (8) after rainwater sand drain (9) is removed sediment (10), its rain sewage input just Xia Shui river course, back rain clear water (11) is then imported the water river course, and scum (12), until river mouth, downstream sluice (13) overflow in edible waters.

In accompanying drawing 2:

The lower floor in double-deck river course is the Xia Shui river course (2) and the interflow water factory (7) of dry flow sewage (1) and first rain sewage afflux; And the upper strata be the shunting purification draining (4) of water factory or rain stream draining and after the overflow of rainwater sand drain the last water river course (5) of rain clear water (11) afflux.

In accompanying drawing 3:

The river blowdown comprises dry flow sewage (1), just rain sewage or river water transfer (15), riverbed mud (16) and household garbage (17), burnt gas (18) and nitrogenous lonely (19), all change the liquid state classification preliminary treatment and the comprehensive purifying thereof of river waterworks over to and reclaim the platform real estate of the three wastes (water, slag, gas) pollution treatment resource and the compound building foundation of river waterworks thereof comprehensively, the fully invested of its river purifying system that is enough to rise in value.

In accompanying drawing 4:

By dry flow sewage (1) input category pipe well (21), remove its sediment (10) and scum silica frost (12), pipe well (23) is collaborated in input again, and the combined sewage (22) of removing sediment with preceding first rain sewage of the back rain clear water (11) of rain stream draining (8) overflow or river water transfer (15), promptly all import anoxic pipe well (24) and denitrogenation with returned sludge and backflow sewage, its nitrogenous be sick of (19) feed back the interflow pipe well, and carry the lonely stirring and the kinetic hydraulic energy of combined sewage as gas: anoxic sewage is then imported aerobic pipe well (25) and oxygenation, the aerobic sewage that its input air (29) and gas are carried, the anoxic that promptly refluxes pipe well and input shunting pipe well (26) and dephosphorization, its phosphorus containing sludge (20) then refluxes behind anoxic pipe well and the output excess sludge, and shunting it, to purify draining (4) be that qualified discharge is in unedible purification waters (30).

In accompanying drawing 5:

The hydraulic detention time of river blowdown purified treatment is:

Classification pipe well (21): 2 hours;

Interflow pipe well (23): 12 hours;

Anoxic pipe well (24): 5 hours;
