Description
Technical field
The utility model belongs to water pollution control and sewage treatment field, in particular to one kind reaches in line or reuse standard
Filter pipe formula septic tank up to standard.
Background technique
Septic tank is a kind of important sanitary sewage pretreatment facility, but handles sanitary sewage using septic tank merely,
Related in line or reuse standard cannot be reached, it need to the in line or reuse of ability after advanced treating.And the sanitary sewage dispersed is deep
It spends treatment facility investment and operating cost is higher, therefore build sewage collecting pipe network to build again concentration sewage after the sewage collecting of dispersion
Treatment plant carries out advanced treating.It is raw that here it is " septic tanks+sewage collecting pipe network+centralized wastewater treatment factory " of current extensive utilization
Sewage treatment mode living.
The investment of existing sanitary sewage disposal mode and operating cost include septic tank, sewage collecting pipe network and concentration sewage
Three parts for the treatment of plant.If pretreatment and advanced treatment requirement can be met simultaneously by developing one kind, sanitary sewage disposal is reached
To in line or reuse standard septic tank up to standard, then the investment of septic tank up to standard and operating cost will increase；If up to standardization excrement
Pond increases the Payment control of part within the scope of the investment and operating cost of sewage collecting pipe network and concentration sewage treatment plant, then reaches
Mark septic tank economically has feasibility.
Septic tank up to standard can not only reduce the investment and operating cost of sewage treatment；And present mode dirt can be eliminated
Water harnessing effect is limited to the limitation of pipe network collection efficiency；Simultaneously sanitary sewage handle it is up to standard after can nearby Reuse on Environment,
It flushes the toilet, road-cleaning, field irrigation etc.；In addition enter water body after sewage treatment is up to standard, water body purification ability can be utilized as early as possible, into
One step degradation of contaminant.
About investing.According to related specification requirement, septic tank hydraulic detention time is 12 ~ for 24 hours, when from hydraulic retention
Between see, the residence time that septic tank meets most sewage treatment process requires, that is to say, that using existing septic tank
Volume can also build advanced treatment apparatus, and the bio-contact oxidation that biochemical, precipitating and filtering combine together is used to filter
Sedimentation basin will greatly save volume requirement.In addition if it is extensive, mass production, septic tank up to standard is installed on a large scale,
The investment cost of facility can reduce.
In terms of operating cost, blower needed for septic tank up to standard, the equipment such as water pump are less, the consumption such as water power, medicament expense
Measure it is less, instrument appliance control require it is low, can be higher than existing septic tank in terms of operational management, but also have ready conditions can for increased expense
Within the scope of to control in sewage collecting pipe network and concentrate the operating cost of sewage treatment plant, in addition may be used also if reuse
To generate certain economic value.
The main technique of existing septic tank up to standard uses bio-contact oxidation filtering settling pond, with filter pipe and its mistake
The it is proposed of device is filtered, the treatment effeciency of septic tank up to standard can further improve, therefore propose filter pipe formula septic tank up to standard.
Summary of the invention
For the treatment effeciency for further increasing septic tank up to standard, the utility model proposes filter pipe formula septic tanks up to standard.
Its main units includes excrement slag bath, collecting-tank, clear water reserviors and filter pipe pond；Wherein excrement slag bath is equipped with duct type grid；Collection
