In order to strengthen sewage flowing in each pond body and between each pond body, also be provided with a plurality of promotion sewage impeller mobile along annular space in each pond body.Particularly, in the both sides of each partition wall, one group of impeller all is set, the plug-flow opposite direction of two groups of impellers.
(5) settling tank 10 comprises the settling tank body, and wall is provided with and is tilted to down, connects the water entry to bottom within it, and water-in is formed on the top of this water entry.Be provided with the inclined tube layer at the middle part of settling tank body, the clarification water layer is formed at its top, shunting layer is formed at bottom, at the edge of clarification water layer, is provided with water port.Bottom at the settling tank body also is equipped with shore pipe, and an end of this shore pipe extend out to the outside of settling tank body.
In this example, water entry is formed by the sidewall of sidewall, the inclined tube layer of clarification water layer and the dividing plate that is positioned at inclined tube layer bottom.The breach of dividing plate below forms sewage and enters the passage of shunting layer.
During actual the use, in the outer end of shore pipe, connect the circulating sludge pump, mud is pumped to follow-up treatment facility.
(6) sand filter 9 comprises that sand filtration process and washed-out sand process between the ，Ge unit, a plurality of sand filtrations unit be set up in parallel are independent of each other.Each sand filtration unit comprises casing, and the middle part in chamber is provided with sand filter blanket within it.
Also be provided with filtering water out, washed-out sand water inlet, sewage inlet and washed-out sand dewatering outlet on casing, wherein the height of filtering water out and washed-out sand water inlet is greater than the height of sand filter blanket, and the height of sewage inlet and washed-out sand dewatering outlet is less than the height of sand filter blanket.Particularly: the height of filtering water out is greater than the height of washed-out sand water inlet, and the height of sewage inlet is greater than the height of washed-out sand dewatering outlet.For the ease of connecting exterior line, filtering water out, washed-out sand water inlet, sewage inlet and washed-out sand dewatering outlet all are arranged on the same sidewall of casing.
In order to strengthen the effect of washed-out sand, be convenient to the control of washed-out sand operation, this example separately arranges washed-out sand water and carries supervisor, and the washed-out sand water inlet of each sand filtration unit is all carried to be in charge of by washed-out sand water and is connected to washed-out sand water conveying supervisor, at each washed-out sand water, carries to be in charge of also to be respectively equipped with valve.Valve herein can be selected manually-operated gate or electrically operated valve, is elected to while using electrically operated valve, coordinates the Controlling System for the treatment of station can realize automatic washed-out sand.
(7) photochemical catalytic oxidation groove 8 comprises cell body, be provided with water inlet at the one end, the other end is provided with water outlet, in cell body along effluent stream to also being arranged alternately a plurality of perforated plate for catalyst of nano titanic oxide catalyst and irradiation fluorescent tube layers that formed by a plurality of UV ultraviolet lamp tubes that are set up in parallel of being attached with.
In order to strengthen the oxidation effectiveness in cell body, this example also comprises oxygen supplementing device, and this device is for being layed in the pore aeration tube bottom cell body, and source of the gas is gas blower or pressurized air.
The impeller adopted in above-mentioned pretreatment pool 12 and reaction tank 11 can also can adopt pneumatic impeller for electronic impeller.The structure of pneumatic impeller is: the air intake supervisor who comprises straight tube-like, an end the air intake supervisor is provided with many arms that all communicate with it, be equipped with the air outlet tube communicated with it in the outer end of every arm, have the angle that is greater than 90 ° and is less than 180 ° between air outlet tube and air intake supervisor, this angle preferred value is 37 °.
The source of the gas of above-mentioned pneumatic impeller is from the air blast machine room of acoustic booth 1 lower floor.
The mode of connection of each treatment facility is:
Be connected to the sewer line of residential quarter every the sewage inlet of dirty ditch 5, its sewage outlet is connected to the water-in of pump well 4, and it is interior temporary that the sewage after after the dirt processing, having removed agglomerate floater and macrobead solid pollutant enters pump well 4.The rising pipe of pump well 4 is connected on the thrust-augmenting nozzle of pretreatment pool 12, under the control of Controlling System, the sewage in pump well 4 by the first water pump and the second water pump automatic loading water to pretreatment pool 12.Pretreatment pool 12 cross the wall mouth be connected to reaction tank 11 water inlet the wall mouth, the water-in that the wall mouth is connected to settling tank 10 is crossed in the water outlet of reaction tank 11.The water port of settling tank 10 is connected to the sewage inlet of sand filter 9.The primary water outlet of sand filter 9 is connected to the water inlet of photochemical catalytic oxidation groove 8, and the water outlet of photochemical catalytic oxidation groove 8 is connected to the entrance of fine filtering groove 6.Fine filtering groove 6 is arranged in tank 3 inside.
The middle water of middle tank 3 interior storages can direct reuse, when the reuse speed of central water is less than formation speed, need will be unnecessary middle water discharge.Therefore also be provided with upflow tube on middle tank 3, the end of this upflow tube forms the discharge outlet 7 of water in surplus.
In this example, the mud that settling tank 10 bottom settlingss obtain carries out circular treatment, therefore its circulating sludge pump outlet is connected to the thrust-augmenting nozzle of pretreatment pool 12 by pipeline, the sewage connection returned sluge of pumping in pump well 4 is mixed mutually.Adopt the benefit of above-mentioned processing mode to be, the sludge quantity that whole treatment station produces is less, and excess sludge is also less, can regularly transport outward processing.
The working process of this example: the sanitary sewage of being collected by the sewer line of residential quarter is introduced into every the interior removal agglomerate floater of dirty ditch 5 and macrobead solid pollutant.Afterwards, it is interior temporary that sewage enters pump well 4, then by water pump, sump pump is delivered in pretreatment pool 12 and carried out pre-treatment.The treating processes that pretreatment pool 12 completes comprises being mixed and the organism in sewage is carried out to acidification hydrolization etc. of peak regulation, sewage and returned sluge of hydraulic load.Afterwards, sewage enters in reaction tank 11 and carries out aerobic and anaerobic reaction and process, and at sewage, during along tertiary circulation shape spatial flow, successively repeatedly experiences the oxygenolysis of aerobic bacteria, the nitration denitrification reaction process of anerobe.Afterwards, sewage enters in settling tank 10 and carries out solid-liquid separation.The sewage of separating enters in sand filter 9 and carries out sand filtration.Afterwards, the primary water that sand filtration obtains is sent in photochemical catalytic oxidation groove 8 and is carried out degree of depth catalytic oxidation treatment, further removes pollution substance.Finally, sewage enters in fine filtering groove 6 and carries out fine filtering, the solia particle of filtering inside.The middle water obtained enters in middle tank 3 and is stored.
Exhaust fan and exhaust duct are installed in this treatment station, the foul gas in station is imported in reaction tank 11, through the biological treatment of aerobic bacteria and anerobe, eliminate peculiar smell, prevent from disturbing residents.
