Abstract

The present invention relates to a method for treating sewage in urban water areas and purifying waste gas, which utilizes a liquid classification pretreatment method of using waste gas (4) to impel sewage (1) to carry waste slag (2) and a biochemical synchronous treatment method of the confluent sewage of the sewage in urban water areas, such as rivers, channels, lakes, oceans, etc. The present invention can comprehensively recover the pollutant treatment resources of three wastes (waste water, waste slag and waste gas) in water areas for treating pollutants by using the three wastes and comprehensively treating pollutants. The pollutant treatment resources comprise building filling materials (7), regenerated raw materials (9), chemical raw materials (6), industrial materials (22), agricultural fertilizers (27), purified water bodies (30), and the basis materials of landed estates and the combined environmental buildings of the landed estates in water areas.

Description

The method of urban sewage treatment and waste-gas cleaning

(1) technical field:

The present invention relates to waters sewage work and pollution treatment industry thereof, especially waste gas promotes the method that waste water delivery waste residue changes liquid pretreated urban sewage treatment of classification and waste-gas cleaning over to.

(2) background technology:

Existing municipal sewage treatment, solid waste disposal such as water bed mud and domestic refuse, industry and life chimney and various car, the moving combustion exhaust that discharges of the flow of ship are all dealt with separately on land, and cause urban waters simultaneously, soil and topsoil or its secondary pollution.

(3) summary of the invention:

The method that the purpose of this invention is to provide a kind of urban sewage treatment and waste-gas cleaning not only can make the municipal effluent need not the long distance blowdown and the processing of founding the factory on land; And, in urban waters.Utilize combustion exhaust potential to promote the pulverizing waste residue of municipal effluent delivery solid waste, change the biochemical synchronous processing of combined sewage of liquid classification over to, and reclaim it and reach with the pollution treatment resource of dirty pollution treatment and comprehensive anti-pollution and cause the system purification that urban sustainable development is polluted.

The object of the present invention is achieved like this: in urban waters, utilize municipal effluent delivery to pulverize the slag inclusion waste water of waste residue, be mixed into hold concurrently gas lift well and double gas of input with combustion exhaust and fall well: it is characterized in that the double gas lift well that seals and double gas fall well air operated circulation water lift is set in well, promote the double gasoloid of circulation, and shunt the double gas of gasoloid input of holding concurrently and divide well, double gas divides well to get rid of acid-containing solution and sinking melt cinder in the shaft bottom; Jing Ding gets rid of surplus air and come-up stream slag; Double gas divides the combined sewage that is removed acid solution, sediment, air and scum silica frost of well output, and biochemical synchronous processing is implemented in series connection.Simultaneously, in urban waters, utilize municipal effluent delivery to pulverize the slag inclusion waste water of waste residue, be mixed into hold concurrently gas lift well and double gas of input with input air and fall the well circulation gasoloid of holding concurrently, and the shunting gasoloid input gas of holding concurrently of holding concurrently divides well; And independent waste water and combustion exhaust are mixed into circulation that well falls in input waste gas gug and the waste gas gasoloid of holding concurrently, i.e. the shunting gasoloid input gas-liquid of holding concurrently is divided well; It is characterized in that: double gas divides the liquid state of well and the gas-liquid Fen Jing two ends output pretreated combined sewage of classifying, and in parallelly implements biochemical synchronous processing.In addition, supply water as various cars, the moving exhaust of the flow of ship by independent, the liquid state classification water that independent waste-gas cleaning is handled, be in row's gas-liquid pipe and molten gas-liquid pipe of sealing, be in charge of the surplus air of emission abatement and chemical industry processing of periodically exporting acid-containing solution and independently water supply by double gasoloid of combustion exhaust promotion circulation and gas-liquid thereof.The waters pollution treatment resource that reclaims comprises the building filler of sinking melt cinder; The regenerative raw materials of come-up stream slag; The industrial chemicals of materialization acid-containing solution; The biochemical nitrogenous lonely industrial material and the agricultural fertilizer of phosphorus containing sludge; Purify urban water-body and the waters real estate and the compound environmental architecture basis thereof of draining.

Owing to adopt such scheme, can not only be with radical cure urban waters, soil and topsoil, and, reclaim the three wastes comprehensively, comprise waste water, waste residue and waste gas, the purification system of urban sustainable development integrated environment.

(5) embodiment:

In Fig. 1:

The slag inclusion waste water 3 of waste residue 2 is pulverized in municipal effluent 1 delivery, falls the liquid classification of well 12 internal recycle with the double gasoloid 5 that its combustion exhaust 4 promotes at double gas lift well 11 and double gas; Wherein, be partially soluble in the sulfurous gas of water and carbonic acid gas and all be recycled pressurization or add agent and be generated as acid solution, and divide well 13 sinking backflow acid-containing solutions 6 through the gas of holding concurrently, circulation concentrates or crystallization, is promptly handled by liquid state sinking melt cinder 7 shunting output melt cinders; And the liquid surplus air 8 of removing acid anhydrides and flue dust then is water insoluble purifying air of liquid come-up stream slag 9 shunting outputs thereupon.The liquid combined sewage 10 of removing acid solution, sediment, air and scum silica frost is its biochemical synchronous processing of input, wherein, fall in anaerobism gug 14 and anaerobism and to promote the nitrogenous of circulation anaerobic solution 21 in the well 15 and be sick of 22, then for divide the denitrogenation waste gas of well 16 from anoxic, and aerobic gug 17 and aerobic fall in the well 18 be promote by input air 24 the aerobic solution 25 of circulation and aerobic minute well 19 reflux aerobic time mud 26, remove phosphorus containing sludge 27 and surplus air 28 after, purify drainings 30 through 29 outputs of sterilization solvent again.

In Fig. 2:

Combined sewage 10 is to catchment from parallel connection after slag inclusion waste water 3 and the liquid respectively classification pre-treatment of independent waste water 31; The former promotes the double gasoloid 5 of circulation by input air 24 for it, reclaims purer sinking melt cinder 7 and come-up stream slag 9; The latter then falls in the well 33 the independent loops gasoloid of holding concurrently with combustion exhaust 4 at waste gas gug 32 and waste gas, and in gas-liquid is divided well 34 purer acid-containing solution 6 and the deacidification sewage 35 of shunting.

In Fig. 3:

Independent water supply 36 is to move the independently liquid state classification water of waste-gas cleaning processing of exhaust as various cars, the flow of ship, and in row gas-liquid pipe 37 and molten gas-liquid pipe 38, be in charge of the chemical industry that 39 shuntings purify surplus airs 8 and periodically export acid-containing solution 6 and handle and independent water supply by combustion exhaust 4 promote to hold concurrently gasoloid 5 and gas-liquid thereof.
