Description
Technical field
The present invention relates to environmental projects, refer in particular to municipal domestic sewage processing method.
Background technique
Water is Source of life, and all things on earth, which is grown, be unable to do without water.Water is both the primary condition of human survival and the preciousness of the mankind
Resource is the spring of life.Water has pushed the economic development of the mankind, and the history of the mankind is exactly the littoral hair in major river, ocean
What exhibition was got up.One mentions water, this is often again familiar with the mankind a kind of substance only.
General usual 5 to 7 tons of domestic water in January of three-person household, wash water accounts for the 1/3 of whole household waters, water closet
With the 1/3 of water spot household water, have a bath, washing one's face accounts for nearly the 1/3 of household, water for kitchen use with water and account for about the 1/10 of household water.
Existing pumping equipment is that closestool draining (Heisui River) and washing draining (buck) share a pipeline, by sewage discharge to cell
Septic tank, kitchen drainage are then exhausted directly to municipal drainage pipe network.What small region sewage treatment was most difficult to is usage on black water, to technique and is set
It is standby more demanding, and then various impurity contents are less easy to handle for urban life cell buck, a large amount of Heisui River and buck at this stage
The difficulty and cost of sewage treatment are considerably increased after mixing.Although there is dealer to propose the scheme of various small region sewage treatments,
But it is most of to mostly use Heisui River and buck mixed processing, or again by Yu Shuiyu after being first separated by solid-liquid separation in Heisui River in cell
It is handled after buck mixing.All need as treatment process through sewage → conditioning tank → primary sedimentation pond → biological contact oxidation pond →
Secondary sedimentation tank water outlet, since Heisui River needs to be handled in cell, so septic tank is still built, and multiple processing ponds, meeting
Biggish space is occupied, in addition septic tank and blast pool can more or less generate foul smell, influence cell environment health.
General usual 5 to 7 tons of domestic water in January of three-person household, wash water accounts for the 1/3 of whole household waters, draws water
Closestool is had a bath, washing one's face accounts for nearly the 1/3 of household, water for kitchen use with water and account for about the 1/ of household water with the 1/3 of water spot household water
10.Existing pumping equipment is that closestool draining (Heisui River) and washing draining (buck) share a pipeline, and sewage discharge is arrived
Cell septic tank, kitchen drainage are then exhausted directly to municipal drainage pipe network.What small region sewage treatment was most difficult to is usage on black water, to technique
It is higher with equipment requirement, and then various impurity contents are less easy to handle for urban life cell buck, at this stage a large amount of Heisui River and
The difficulty and cost of sewage treatment are considerably increased after buck mixing.Although there is dealer to propose the side of various small region sewage treatments
Case, but it is most of mostly use Heisui River and buck mixed processing, or again will be remaining after being first separated by solid-liquid separation in Heisui River in cell
Water is handled after mixing with buck.It is all needed as treatment process through sewage → conditioning tank → primary sedimentation pond → bio-contact oxidation
Pond → secondary sedimentation tank water outlet, since Heisui River needs to be handled in cell, so septic tank is still built, multiple processing
Pond can occupy biggish space, and in addition septic tank and blast pool can more or less generate foul smell, influence cell environment health.
Chinese patent 104291520A discloses a kind of sanitary sewage disposal and reuse method, and sanitary sewage is carried out classification row
It puts, the Heisui River of high concentration and the buck of low concentration is divided into according to the difference of sewage property and source, after Heisui River is discharged from, is passed sequentially through
Anaerobic treatment pool, aeration contact-oxidation pool, the high resistant ecological pool of aeration, the low resistant ecological pool of aeration and ecological precipitation process pond,
Treated enters conditioning tank after Heisui River merges with buck, and the processing of underground percolating device, the ground are sent into after conditioning tank is adjusted
The water of lower percolating device processing is back to after disinfection flushes the toilet or qualified discharge.This method is also required to Heisui River in cell
It is handled, the Heisui River then handled obtains middle water after mixing progress secondary treatment with buck again, and middle water can be used to rinse
Lavatory, although Heisui River and buck separately discharge, Heisui River is directly handled in cell, and treated, and Heisui River is mixed with buck again
Secondary treatment again treatment process and equipment cost increase to be not appropriate for promoting.
Chinese patent 109110963A discloses a kind of kitchen and bath's sewage water treatment method, includes the following steps: 1) to arrange kitchen
Sewage out, is filtered immediately after the exit, realizes the separation of solid and liquid；2) for separation after liquid sewage, according to
By oil and water difference of specific gravity, water-oil separating is realized by liquid level overflow；3) to toilet discharge sewage, after the exit immediately into
Row disinfection, is then filtered, and carries out the separation of solid and liquid；4) step 2) is carried out by oil, water waste water obtained after separation
Then disinfection treatment converges by the sewage being separated by solid-liquid separation with step 3), and carries out further filtration treatment；5) step 4) is passed through
Waste water after crossing further filtration treatment, after carrying out advanced treating, qualified discharge or reuse.Although the program is dirty by kitchen and bath
Water is separately handled, but its by Heisui River sewage and solid portion solid-liquid separation treatment is carried out directly in cell is unrealistic
, secondly, the sewage in Heisui River is also required to be handled in cell, finally, the program will be direct after all sewage treatments
It is discharged, the effect of saving is not achieved.
Summary of the invention
Do not need to handle Heisui River in cell the purpose of the present invention is to provide one kind, only need to lower cost and compared with
Housing estate wastewater processing method simple device processing buck and recycled.
To reach above-mentioned purpose, a kind of municipal wastewater processing method of the present invention, by the draining of each family life closestool, washing
Draining, kitchen drainage are discharged with independent sewer pipe respectively, in which:
1), closestool draining is uniformly discharged into independence after being set to the micromill of each residential quarters user and intercepting grid
The municipal Heisui River pipe network of setting, the usage on black water factory for being transported to concentration through multistage delivery pump carry out extensive use of chemical fertilizer processing；
2), washing draining is filtered after this residential quarters is concentrated, forms water in primary after disinfection and sterilization, and primary middle water is passed through pump
It is sent in the primary middle water tank of this residential quarters roof, is supplied water by pipeline to the closestool of each household, which can also do
To rinse road surface water；
3), kitchen drainage is filtered after this residential quarters is concentrated, precipitates mud, is passed through under conditions of flow velocity < 0.005m/s
Oil strain and biomembrane oil strain are adsorbed, no grease is obtained, will be accessed without this residential quarters of grease in washing drainpipe and carry out the 2) step
Processing；
4), second step generate primary middle water through biological removal of nitrogen, dephosphorization, disinfection and sterilization, PH adjust, active carbon filter to be formed it is secondary
Middle water is directly used in this residential quarters slurry；
5), secondary middle water and tap water are formed straight after PP cotton, active carbon, UFO ultrafiltration membrane, reverse osmosis (RO) film, active carbon processing
Drinking-water can cross stainless steel pipes and be transported in each user family in this residential quarters.
After above scheme, since Heisui River (closestool discharge sewage) is not needed through cell septic tank or Heisui River no longer
Handled in cell, remaining urban life buck only has a small amount of silt, and existing cleaning product mostly use it is low-phosphorous
Formula, so only handle less pollution buck, greatly reduce the equipment requirement and technology difficulty of sewage treatment；In addition it removes
Outside the direct emission of Heisui River, other drainings are secondary or utilize three times, and Heisui River, which can recycle, makees fertilizer, so fully achieving
Zero-emission；Again, only Heisui River accounts for the 1/3 of Water usage, cook and drink point ratio it is smaller, it is possible to save use
Water nearly 2/3 presses whole nation You2.5Yi Hu urban households, and by water-saving 10,000,000,000 tons or more, this will mitigate to ground water significantly within 1 year
Exploitation, also pressure force-summing device lesser to water factory and water supply line and capital investment.
Detailed description of the invention
Fig. 1 is flow diagram of the present invention.
Specific embodiment
In order to describe the technical content, the structural feature, the achieved object and the effect of this invention in detail, below in conjunction with embodiment
And attached drawing is cooperated to be explained in detail.
Referring to Fig. 1, housing estate wastewater processing method of the present invention, closestool draining, washing draining, kitchen drainage are distinguished
It is discharged with independent sewer pipe, is respectively provided with independent closestool water discharge spout road, all closestool water rows in each resident
It puts pipeline and accesses unified municipal Heisui River pipe network.Micromill is arranged in the closestool water discharge spout road of each household will be in closestool water
Solids smash, to prevent pulverizer damage from the fixture leaked through being made to block pipeline, set in the closestool water discharge spout road of each household
There is interception grid, entire pipe network will not in this way blocked, is transported to collection through multistage delivery pump into the Heisui River of municipal Heisui River pipe network
In usage on black water factory carry out extensive use of chemical fertilizer processing.
Due to urban life relative clean, and existing cleaning product is more low-phosphorous, more ring what, so wash water is opposite
Cleaning, the washing draining of cell form water in primary after being filtered (silt, hair, other solids), disinfection and sterilization after concentrating,
The boosted pump promotion of water is sent in the primary middle water tank of roof in primary, is supplied water by pipeline to the closestool of each household, daily life
Middle buck and kitchen water consumption are significantly larger than closestool water consumption, so closestool is no longer needed from running water pipe water receiving, extra one
Secondary middle water can also road surface etc. is lower to water quality requirement to use water as rinsing.Since the water source of primary middle water is more clean
Cell buck does not reprocess Heisui River, and primary middle water is used only to rinse closestool or road surface, it is desirable that lower, it is possible to most
Row is handled when simple technique and equipment, is greatly reduced cost, is not also needed too big space.
Kitchen drainage is filtered after concentrating, precipitates mud, passes through absorption oil strain and life under conditions of flow velocity < 0.005m/s
Object membrane filtration oil, obtains no grease, the relatively smaller mud of the dish even clean vegetables of present cell life, the oil content in kitchen drainage also compared with
It is low, so filtering is deoiled namely is easily realized.It will be accessed without grease in washing drainpipe and carry out water in primary together with washing draining
Processing.The Heisui River for having handled about 1/3 less in the treatment process of primary middle water is measured, so the amount of water is about that water applies flexibly water in primary
2/3.
Water applies flexibly the 1/3 of water less than water for rushing closestool or washing the outer residue of road sections in primary, this part once in water
It is adjusted by biological removal of nitrogen, dephosphorization, disinfection and sterilization, PH, active carbon filters and to form secondary middle water and be directly used in slurry, this mistake
Journey mainly by membrane technology handle, mainly using hollow-fibre membrane (in this technique use 8 Φ 200 hollow-fibre membrane, into
Water flow maintains 12 m3/h, and water outlet maintains 10 m3/h or so, backwash per hour 10 minutes, protects hollow-fibre membrane), with
The water designed afterwards in design early period will will not be such that film blocks, keep the normal operation of system in this way by very fine filtering.
Its operating pressure is 0.1-0.3MPa, and activated carbon adsorption passes through activated carbon adsorption by the water that film comes out, and deodorizing is de-tasted and can also be inhaled
(1 kilogram of active carbon handles water 8-12 to colloidal substance in attached water if activated carbon adsorption system is preposition before membranous system
Ton, the service life of active carbon can be very short, replaces active carbon quickly, and its postposition is then preposition 20 times or so, improves active carbon
Service life, 1 kilogram of active carbon of active carbon postposition dechlorination handle 30 tons of water or so) this process activity canister is designed as daily
Backwash is primary, and 10 minutes every time, tank design was Φ 1600, and effective height 2000, clear height 2800, practical loadings are 75%.
Since this part only handles the cleaner primary middle water less than domestic consumption 1/3, thus the requirement of the treating capacity of equipment and
Technical difficulty requires to substantially reduce, and is suitble to the inexpensive demand of residence district.
To part higher gears cell, water process three times can be carried out again so that on the basis of secondary middle water (tap water can be filled into) and connect
Direct drinking is obtained, through stainless steel pipeline into user family, water process surpasses water through PP cotton, active carbon, UFO three times
Direct drinking is formed after filter membrane, reverse osmosis (RO) film, active carbon processing.
All water treatment technologies are all made of existing public technology, the not reinflated explanation in this place in the present invention.
Compared with prior art, the present invention no longer maximum Heisui River of processing difficulty in residence district, while reducing 1/3
Usage on black water amount, as long as a simplest technology of sewerage disposing can be realized, secondary sewerage disposing amount be less than daily life
The cleaner primary middle water of water 1/3 is applied flexibly, thus it is all lower to processing setting standard requirements and treating capacity requirement, lower
It can be realized under cost.All sewage of the present invention can recycle, and the usage amount of complete hoop structure, tap water also subtracts
It is few to original 1/3, therefore low cost of the invention, zero-emission, the scheme of more piece about are worthy to be popularized.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
