Description
Technical field
The present invention relates to sewage disposal, the more particularly to processing system and method for confluence of rainwater and sewage sewage.
Background technology
At present, the processing mode of confluence of rainwater and sewage sewage mainly has following two modes:
1. combined sewage is by the way that after grid, high efficiency filter, precipitate and separate treatment, tail water enters water body.Processing mode profit
The units such as Densadeg, Actiflo, Lamella Clarifier are the commercial treatment device of shaping, have applied
In light contamination data analysis.The deficiency of which is:
Core concept is that the classical coagulation in Water purification is theoretical, equipment it is critical only that sewage mix with flocculant and
Mud-water separation process.The method of traditional mixing-flocculation-precipitation, with mixed effect is poor, mud-water separation speed is low, separates effect
Really poor deficiency so that flocculation sediment treatment effect is general, and water outlet is generally kept in secondary effluent standard.Then there is researcher to exist
It is improved on the basis of coagulant, flocculation aid and blending agent, enhanced coagulation, but these methods have cost of investment high, no
Easy to control, dielectric film filter rate is low, but to the poor removal effect of the ammonia nitrogen in water outlet, it is impossible to ensure that Tail water reuse standard carries mark to
The effect of level B.
2. by transforming pipeline, build regulate and store, storage pool, collect sewage directly by gravel bed treatment filter heel row enter water
Body.The deficiency of which is:
Sewage is directly entered gravel bed filtering without precipitation process, and sewage SS contents are high, easily causes gravel bed and blocks, and by
It is relatively low in hydraulic load so that floor space is big, the speciality with construction cost, maintenance management high cost.
The content of the invention
In order to solve the deficiency in above-mentioned prior art, the invention provides a kind of high treating effect, easy care
The processing system of confluence of rainwater and sewage sewage.
The purpose of the present invention is achieved through the following technical solutions:
A kind of processing system of confluence of rainwater and sewage sewage, the processing system of the confluence of rainwater and sewage sewage includes:
Inspection shaft, the inspection shaft receives rainwater, sewage, and inside sets grid;
Processing pond, the processing pond includes:
Mixed zone, the mixed zone bottom is installed by aeration unit;The water of the inspection shaft output send the mixed zone;
Aeration unit is installed in reaction zone, the reaction zone bottom, first is set between the mixed zone and reaction zone and is isolated
Part, the water in mixed zone climbs over first separator and enters in reaction zone;
Dosing unit, the output end of the dosing unit connects the mixed zone;
Settling zone, sets inclined tube in the settling zone;Second separator is set between the reaction zone and settling zone, is mixed
The passage that water in area is climbed between the bottom wall of second separator and processing pond enters in settling zone;What the settling zone was produced
The clear water of the mixed zone, generation is sent to send the artificial swamp in the part of sludge.
The present invention also aims to provide a kind of processing method of confluence of rainwater and sewage sewage, namely above-mentioned processing system
Method of work, the dirty processing method for closing sewage of the rain is comprised the following steps:
(A1) confluence of rainwater and sewage sewage enters in inspection shaft, and part dirt is trapped, and sewage is sent in processing pond;
(A2) sewage, flocculant and sludge enter in the mixed zone of processing pond, mixed zone bottom aeration;
(A3) sewage is crossed separator and is entered in reaction zone, and reaction zone bottom aeration, reacted sewage enters settling zone;
(A4) sewage is upward through the inclined tube in settling zone, and sludge settling, the clear water on upper strata send artificial swamp, the portion of sludge
Send the mixed zone;
(A5) clear water is further purified in artificial swamp, afterwards fed downstream.
Compared with prior art, the device have the advantages that being:
1. use microbubble aeration mode, it is possible to increase mixed effect, solve current Dead Core Problems;
Microbubble aeration can improve dissolved oxygen in water body, be conducive to the lifting of advanced treating effect;
2. under air supporting state, be conducive to the removal of suspension, shorten the sedimentation time, reduce floor space;
3. ecological gravel bed carries out purified treatment under conditions of it need not be aerated to sewage, not only reduces processing cost,
It is easy to maintenance management simultaneously;
Ecological gravel bed alternately plants the plants such as canna, aquatic iris, and intensified denitrification and dephosphorization improves effluent quality and refers to
Mark, mark to one-level B water outlets is carried by traditional secondary effluent.
