Description
Technical field
The invention belongs to technical field of sewage more particularly to a kind of domestic sewage treatment process.
Background technology
As water pollution problems and water resource lack, problem is increasingly serious, and the processing that people increasingly pay attention to sanitary sewage is asked
Topic.Large quantities of town dweller's community domestic wastewater treatment facilities are completed at present, such facility is mainly using buried
Biological Contact Oxidation Process form.Facts have proved the technology, there are many defects：First, the facility for being embedded in underground is more difficult
It manages and there are monitoring blind areas；Secondly, buried facility service life is short, and repair and maintenance is difficult；Furthermore such treatment process
Treatment effect can only meet the requirement of qualified discharge, it is impossible to by sewage disposal into Treated sewage reusing, this equally causes water resource
Loss.
Invention content
The present invention provides a kind of high treating effect to solve technical problem present in known technology, ultimately forms middle water
Reuse is to save the domestic sewage treatment process of water resource.
The present invention is adopted the technical scheme that solve technical problem present in known technology：At a kind of sanitary sewage
Science and engineering skill includes the following steps that (1), sanitary sewage are flowed into every in dirty ditch, remove floating material and bulky grain solid pollutant；(2)、
Sewage that step (1) obtains is flowed into pretreatment pool, is diluted and is mixed and the acidifying water under the action of anaerobic bacteria with Chi Rongshui
Solution；(3), the sewage that step (2) obtains is flowed into reaction tank, and biological oxidation is repeated under the action of aerobic bacteria and anaerobic bacteria
It is reacted with nitration denitrification；(4), the sewage that step (3) obtains flows into sedimentation basin and carries out separation of solid and liquid；(5), step (4) obtains
To sewage flow into sand filter in carry out sand filtration filtering；(6), the sewage that step (5) obtains is flowed into photochemical catalytic oxidation slot and is carried out
Depth photochemical catalytic oxidation；(7), the sewage that step (6) obtains flows into fine filtering slot and carries out fine filtering, filters out not tolerant；
(8), water is stored and reuse in being used as in sink during step (7) obtains sewage flows into.
The advantages and positive effects of the present invention are：The present invention provides a kind of domestic sewage treatment process, present treatment techniques
Compared with existing process form, technological process is more reasonable, and sewage is after each step process, floating material therein, big
Grain solid pollutant, larger molecular organics, small organic molecule etc. are filtered out successively and reaction treatment, degree for the treatment of are deeper
Change, pollutant removal is more thorough, and finally formed middle water meets the standard of reuse, has saved water resource.
Preferably：The step of further including sludge pumping to the pretreatment pool that will be deposited in sedimentation basin bottom.
Preferably：It further includes and passes back into the washed-out sand water of sand filter every the dirty ditch the step of.
Preferably：It is further included between step (1) and step (2) and sewage is subjected to temporary step in sump, every
The sewage natural that dirty ditch obtains is flowed into sump, and the sewage in sump is pumped into pretreatment pool.
Preferably：Further include the step of water in residue is subjected to overflow discharge.
Preferably：It is described every dirty ditch, pretreatment pool, reaction tank, sedimentation basin, sand filter, photochemical catalytic oxidation slot, fine filtering
Slot and middle sink are respectively positioned on the ground, form enclosed sewage treating stations.
Description of the drawings
Fig. 1 is the flow diagram of the present invention.
Specific embodiment
It is described in detail such as in order to further understand the content, features and effects of the present invention, the following examples are hereby given
Under：
Fig. 1 is referred to, domestic sewage treatment process of the invention includes the following steps：(1), sanitary sewage is flowed into every dirty ditch
In, remove floating material and bulky grain solid pollutant；(2), the sewage that step (1) obtains is flowed into pretreatment pool, with Chi Rongshui
It is diluted mixing and the acidification hydrolization under the action of anaerobic bacteria；(3), the sewage that step (2) obtains is flowed into reaction tank, good
Biological oxidation and nitration denitrification reaction are repeated under the action of oxygen bacterium and anaerobic bacteria；(4), the sewage stream that step (3) obtains
Enter and separation of solid and liquid is carried out in sedimentation basin；(5), the sewage that step (4) obtains, which flows into, carries out sand filtration filtering in sand filter；(6), step
(5) sewage obtained, which flows into, carries out depth photochemical catalytic oxidation in photochemical catalytic oxidation slot；(7), the sewage that step (6) obtains flows into essence
Fine filtering is carried out in thin lautertuns, filters out not tolerant；(8), in being used as in sink during step (7) obtains sewage flows into water into
Row storage and reuse.
It may still contain not sufficiently reactive pollutant in the sludge that sedimentation basin bottom generates, therefore will be deposited in this example
Circular treatment is participated in the sludge pumping to pretreatment pool of sedimentation basin bottom.
Sand filter needs periodically to carry out washed-out sand, and the solid grain contamination retained in sand filter blanket is washed out.Solid particle is dirty
Dye object is mixed in washed-out sand water, therefore washed-out sand water can not be discharged arbitrarily.The washed-out sand water of sand filter is passed back into every dirty ditch in this example
Solid grain contamination is retained, salvaged by the facility that filters out every dirty ditch by middle carry out circular treatment.
It more swimmingly carries out for the ease of entire technological process, is also set up in this example between dirty ditch and pretreatment pool
It is additionally provided between sump, i.e. step (1) and step (2) and sewage is subjected to temporary step in sump, every in dirty ditch
Sewage natural out is flowed into sump, and the sewage in sump is pumped into pretreatment pool.
