Description
Technical field
The present invention relates to technical field of sewage, be specifically related to a kind of middle water recycling processing system.
Background technology
Middle water refers to various drainings after treatment, reaches the water quality standard of regulation, can be in the scopes such as life, municipal administration, environment reusable undrinkable water.It is exactly a kind of important method of sewage recycling that middle water is recycled, it both can reduce the pollution to environment, can increase again the quantity of available water resources, the comparatively hand basin of cleaning in daily life or the office block particularly, shower drainage, the waste water such as water of condensation, all directly enter behind the water drain mix with other sewage after unified the processing, rather than carry out targetedly individual curing, so not only increase sewage load and treatment time, and these sewage that clean there is no need to carry out comparatively complicated processing originally, carrying out complicated processing has not only wasted the time and has increased processing cost, has also delayed the water circuit utilization.And traditional intermediate water reuse system all is to process reuse for the sewage of enterprise, relatively pay attention to the sewage disposal of enterprise, unit, the processing of the waste water such as routine office work building is paid attention to not, because composition is not identical with the waste water in routine office work building in the waste water of business unit, difference is larger, therefore can not indiscriminately imitate the intermediate water reuse system of enterprise, unit, and traditional Sewage treatment systems is processed thorough not, cause discharging not up to standard, do not carry out the system of middle water Treatment for Reuse for sewage such as office blocks.
The shortcoming of prior art is: existing intermediate water reuse system, be applicable to enterprise, factory, and comparatively the processing of the waste water of cleaning is inapplicable to office block etc., and and existing intermediate water reuse system level of automation low, processing to sewage is not thorough, and management is inconvenient, and hand labor intensity is larger.
Summary of the invention
The object of the present invention is to provide a kind of middle water recycling processing system, be applicable to the Treatment for Reuse of more clear sanitary wastewater, and sewage disposal is thorough, reuse water satisfies the reuse requirement.
For achieving the above object, technical scheme of the present invention is as follows: a kind of middle water recycling processing system, comprise by wastewater streams to frame trough, equalizing tank, biological contact oxidation pond, settling tank, water collecting basin, sand-bed filter, charcoal filter, the disinfection by ultraviolet light pond by pipeline communication successively, described frame trough is communicated with the wastewater drainage pipe road, and the water outlet in described disinfection by ultraviolet light pond is communicated with middle water reuse pipe network.
The sanitary wastewater that this system is applicable to clean is processed, in office building, hand basin in the residential quarter, shower drainage, water of condensation etc., because what the source wet concentration was selected is clear great sanitary wastewater, pollutent in the waste water is mainly with tiny foreign material, suspended substance, organic pollutant is main, therefore mainly remove foreign material with the grid interception, organism is removed in the bio-contact oxidation degraded, precipitation is removed suspended substance, and further by filtering, activated carbon adsorption is carried out advanced treatment, more thoroughly remove the suspended substance in the waste water, organism, and by sterilization removal pathogenic bacterium, satisfy the reuse requirement thereby guarantee to process water.
Adopt said structure, the water outlet of upper level device is communicated with the water-in of next stage device, waste water is in the wastewater drainage pipe road flows into frame trough, owing to containing some tiny foreign material in the waste water, enter follow-up structures, meeting damage equipment, blocking pipe are established mechanical grille with its most of removal in the frame trough, the grid gap is little, can be 2mm.Mechanical grille adopts the rotary machine grid sewage-removing machine, carries out the machine automatization scarfing cinder.
