Abstract
A low-consumption intermediate water treatment device comprises an anaerobic section, a biological filter tower section, and an ultraviolet ray disinfection instrument which are connected in sequence, and is characterized in that sewage is lifted by a sewage pump in a septic tank to enter the anaerobic section from a position above the anaerobic section, flows out of the anaerobic section from a position below the anaerobic section, flows into the top end of the biological filter tower section through a gravity current pipeline, flows out from a position below the biological filter tower section after passing through a biological filtering media, and is discharged after being sterilized by the ultraviolet ray disinfection instrument. Domestic sewage is lifted to the anaerobic section through the sewage pump in the septic tank in one step, reacts for 1 to 2 h, flows into the biological filter tower section, is treated through biological packing, and then flows into the ultraviolet ray disinfection instrument for treatment, and the water quality after the treatment can reach the discharge or recycle standards A of grade I of 'pollutant discharge standards of urban sewage treatment plants'.
Description
Affiliated technical field
The utility model relate to a kind of in water treatment device, be specially adapted to the various WWTs after covil construction use with the building sub-district, handle the standard that water in the back reaches " urban wastewater treatment firm pollutant emission standard " one-level A.
Background technology
At present, middle water treating equipment commonly used mainly are agent set with the biochemical treatment.Most of treatment scheme is that former water discharges through grid, equalizing tank, biological treatment, sterilization at last.The electricity charge account for 60～70% of working cost in its working cost, and main power consumption repeatedly promotes at sewage, equipment such as biological treatment aeration and mud backflow.
Summary of the invention
Energy consumption problem for equipment such as the aeration that repeatedly promotes, carries out a biological disposal upon in the water treatment procedure in overcoming, mud backflows.This practicality patent provides a kind of middle water treatment device.Device is linked in sequence and is formed by anaerobism section, biological filtering tower combined working section, disinfection by ultraviolet light appearance; It is characterized in that: sewage is risen to the inflow of anaerobism section top, below outflow by the cesspool sewage pump; Flow into the top of biological filtering tower combined working through the run by gravity pipeline, after flowing out from the below through biofilter material again through discharging after the sterilization of disinfection by ultraviolet light appearance.
The utility model solves the technical scheme that its technical problem adopted: middle water treating equipment adopt the technology of anaerobism+biological filtering tower combined working, and sewage is handled.
Sewage once rises to anaerobism section cheaply from septic tank, and sewage is carried out Anaerobic Digestion.Remove partial organic substances in the water.The residence time of anaerobism section is 1～2 hour, and volumetric loading is 1～2kgBOD
5/ m
3D.
Flow to the biological filtering tower combined working section through gravity after the sewage process anaerobism section and carry out the aerobic microbiological processing; Effluent stream contacts with the microbial film of its surface attachment through aerobic filler, carries out the solid, liquid exchange; Utilize the interior mikrobe of film with the oxidation operation in the water; Sewage is purified, and simultaneously, mikrobe constantly breeds in the microbial film.In order to keep the activity of aerobe film, the nutritive substance in sewage (organism), also should create a good aerobic condition, promptly must be to the microbial film oxygen supply.This equipment of water runoff can produce internal-external temperature difference, makes device interior produce airflow flowing, reaches the effect of oxygen supply.Need not the auxiliary of other energy.Reach energy-conservation effect.Equipment packing layer thickness is 2m, and volumetric loading is 1.0～2.5kgBOD
5/ m
3D, surface load are 15～35m
3/ m
2D.Guarantee that this section equipment hydraulic detention time is long, the decomposing organic matter amount is big, and unit filter tank area processing power is strong, and floor space is few, and mud does not need to reflux simultaneously.
The effusive water of filter tower section is that the ultraviolet sterilizer of 253.7nm carries out disinfection through wavelength, and ultraviolet irradiation intensity is 1w/m
2Reach effluent standard or the reuse of " urban wastewater treatment firm pollutant emission standard " one-level A at last.
The beneficial effect of the utility model is that the operating energy consumption of water treatment in the reduction reduces floor space.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the schema of the utility model device.
1. septic tanks among Fig. 1,2. anaerobism section, 3. biological filtering tower combined working section, 4. disinfection by ultraviolet light appearance, 5. sewage pump.
Embodiment
The sewage septic tank (1) of flowing through passes through water pump (5) again and rises to anaerobism section (2) to water and carry out anaerobic reaction in Fig. 1, reacts after 1～2 hour, flows to biological filtering tower combined working section (3) through run by gravity, and wherein anaerobism section (2) ground need be higher than the end face of biological filtering tower combined working section.The aerobic filler of this section is handled sewage, removes the partial organic substances in the water, makes in the water organism up to standard, flows to ultraviolet ray again to its disinfecting instrument (4), kills the germ in the water, reaches discharging and reuse at last.
Claims (1)
1. water treatment device in the less energy-consumption; By anaerobism section, biological filtering tower combined working section; The disinfection by ultraviolet light appearance composition that is linked in sequence; It is characterized in that: sewage is risen to by the cesspool sewage pump that anaerobism section top flows into, flow out the below, flows into the top of biological filtering tower combined working through the run by gravity pipeline, after flowing out from the below through biofilter material again through discharging after the sterilization of disinfection by ultraviolet light appearance.
