Description

Micro-integrated domestic sewage treatment device
Technical field
This utility model relates to technical field of sewage treatment equipment, is specifically related to micro-integrated domestic sewage treatment device.
Background technology
In prior art, Chinese patent CN102874925A discloses a kind of sewage biochemical treatment equipment, including casing, the inside of this casing is filled with biological treatment medium (1), being provided with multiple through hole (2) on the diapire of this casing, at least one sidewall of this casing, the inside being provided with described casing communicates and extends to the breather (3) outside casing.This patent also discloses a kind of sewage biochemical treatment equipment group, and it is stacked in the height direction that this sewage biochemical treatment equipment group includes multiple sewage biochemical treatment equipment.In above-mentioned sewage biochemical treatment equipment, sewage enters casing from casing overhead stream, processed by the biochemical treatment medium of box house, in the process processed, extraneous air imports box house by breather, thering is provided the oxygen needed for biochemical treatment medium, sewage is flowed out by the through hole on casing diapire after treatment.But this patent structure is unreasonable, problems with can't be fully solved:
(1) prior art design standard is low
Current Small-scale Sewage Treatment Facilities Effluent criteria is mostly " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level A/B standard and very difficult stably reaching standard.And the ground such as Beijing, Tianjin has started to requirement and reaches provincial standard, water outlet CODcr≤30mg/L, BOD5≤6mg/L, NH4+-N≤1.5 (2.5) mg/L, TN≤15mg/L, TP≤0.3mg/L, SS≤5mg/L effluent quality standard-required is more and more higher, and part region also requires reclaimed wastewater reuse, therefore existing technique can not meet high standard effluent quality requirement gradually;
(2) prior art operating cost is high
The existing conventional miniature main technique of type integrated sewage disposal has: catalytic oxidation, A/O technique, MBR etc., the power consumptions such as stirring, aeration, lifting, backflow, spoil disposal are higher, medicine consumption is also big, so that operating cost is higher, the membrane process of MBR and improvement thereof, cost is also higher, it is impossible to meet energy-saving and emission-reduction requirement;
(3) prior art floor space is big
At present as the ecological treatment method of natural imitation degraded: the technique such as artificial swamp, biological pond, area about 20~30m needed for process ton water2, activated sludge A/O and area about 2~3m needed for improved process process ton water thereof2, catalytic oxidation or area about 1~1.5m needed for SBR PROCESS FOR TREATMENT ton water2, area about 0.5~1.0m needed for MBR PROCESS FOR TREATMENT ton water2;And when land used day by day is nervous, integrated equipment for wastewater treatment also needs further optimization;
(4) prior art device is many and assorted
Existing technological process is general longer, relate to equipment more, submersible sewage pump, agitator, reflux pump, sludge pump, aerator, filter (film), dosing facility, filler etc., add cost of investment, add operation maintenance management difficulty again, the simply scaled down version of Large Sewage Treatment Plant, it is not suitable for management relatively, the regions backward in technique such as rural area, so that a large amount for the treatment of facility leaves unused;
(5) prior art cost of investment is high
At present, integration apparatus ton water cost of investment about 7000 yuan, and scale more subsection cost is more high, main cause is how many by equipment size, equipment, equipment cost taken by themselves causes, and needs reduction production cost badly, seeks the easy device that cost performance is high;
(6) prior art treatment scale is limited
Existing domestic sewage treatment process is by restrictions such as manufacture, transport, occupations of land, disposal ability is relatively low, but also by the restriction of device structure, size, also the impotentia processing of disposal ability too little (scale < 10m3/d), so that the scope of use is limited, the phenomenon ratio of " low load with strong power " is more serious, and some processes (film) is when short-term is without water inlet, system is easily collapsed, and activated sludge need to be tamed again;
(7) poor processing effect during prior art low temperature
In north cold area, during winter, existing integrated equipment for wastewater treatment generally need to take Insulation (external house), thus it cannot be guaranteed that sludge activity, system run all right are poor;
(8) prior art hydraulics is poor;
The hydraulic flow state of existing technique is mostly pulling flow type or is thoroughly mixed formula, comparatively single, but integrated equipment for wastewater treatment is smaller, easily producing short stream or local deposition, sewage can not fully and biological, and reaction rate is low, capacity utilization is also low, and cell body structure, hydraulic flow state need to optimize.
