Preferably: be provided with 2 flase floors in grating tank, the pitch flow on the direction case screen that sewage flows out by sewage reduces.
Preferably: the oxidation ponds at different levels of drop type oxidation pond prolong water (flow) direction and are disposed with filtering net, biofilm packing, and biofilm packing volume and oxidation pond volume ratio are 1:15.
Preferably: the oxidation ponds at different levels of drop type oxidation pond are provided with aerator, and aerator all is connected with Controlling System.
Preferably: be provided with air-lift device in the spoil disposal pipeline in anoxic pond and second pond, air-lift device is connected with Controlling System.
The beneficial effects of the utility model are: the flush-with-ground type sewage treating device that the utility model provides is to take the A/O biochemical process as main, the collection biological degradation, the sewage sedimentation, the techniques such as sterilization are in the oligodynamic sewage treatment device of one, can be widely used in residential quarters, village, villages and small towns, office building, market, hotel, the industries such as restaurant are carried out the processing of sanitary sewage, this device adopts the drop type oxidation pond to replace the biological tank of traditional A/O technique, replaced traditional pumping source by ladder drop type structure and microkinetic electromagnetic control system, reduce electric energy loss, get rid of for guaranteeing mud the normal operation that the low power air-lift device of smooth and easy employing gets final product assurance device, economic and reliable, compact equipment, floor space is few, can all be arranged at underground, the impact of minimizing on surrounding environment, strong shock resistance, management and maintenance is convenient.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model workflow schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Embodiment 1
A kind of buried oligodynamic sewage treatment device, comprise Controlling System and treatment tank group, the treatment tank group is comprised of a plurality for the treatment of ponds, comprises the grating tank 1, equalizing tank 2, anoxic pond 3, drop type oxidation pond 4, second pond 5, sterilization pool 6 and the sludge sump 7 that connect successively, the bottom of described anoxic pond 3 and second pond 5 arranges all the spoil disposal pipeline, by the spoil disposal pipeline, with sludge sump 7, is connected, described drop type oxidation pond 4 is comprised of the tertiary oxidation pond, it between oxidation ponds at different levels, is step-off construction, flow into by sewage the direction that sewage flows out, at the bottom of the pond of previous stage oxidation pond height after at the bottom of the pond in stair oxidation pond height high, oxidation ponds at different levels connect by pipeline, be provided with magnetic valve in UNICOM's pipeline in previous stage oxidation pond and rear stair oxidation pond, be provided with water level sensor in oxidation ponds at different levels, magnetic valve all is connected with Controlling System with water monitor, be provided with sterilizing unit and flow monitoring device in sterilization pool 6, sterilizing unit is connected with Controlling System with flow monitoring device.
Be provided with 2 flase floors in grating tank, flase floor is formed according to a determining deviation and cross bar cross arrangement by band steel, article two, the distance between band steel is pitch, the pitch flow on the direction case screen that sewage flows out by sewage reduces, the oxidation ponds at different levels of drop type oxidation pond 4 prolong water (flow) direction and are disposed with filtering net, biofilm packing, and biofilm packing volume and oxidation pond volume ratio are 1:15.The oxidation ponds at different levels of drop type oxidation pond 4 are provided with aerator, and aerator all is connected with Controlling System, to oxygen supply in drop type oxidation pond 4.Be provided with air-lift device in spoil disposal pipeline in anoxic pond 3 and second pond 5, air-lift device is connected with Controlling System, is responsible for the extraction of mud in anoxic pond 3 and second pond 5.
During work, sewage first flows into grating tank 1, pitch difference due to flase floor in grating tank 1, the pollutent that during inflow, volume is larger first is trapped, the flase floor that the pollutent of small volume is less by pitch is held back, enter afterwards equalizing tank 2, what guarantee that the average of current all measures enters anoxic pond 3, anoxic pond is that 3 denitrogenation processing arrange, the suspension type 3 D elastic filler is set in pond, as the carrier of denitrifying bacterium, returns nitre state ammonia and inferior sour state oxygen in nitrification liquid under the effect of denitrifying bacterium, be reduced into nitrogen, reach the purpose of denitrogenation.Sewage after anoxic pond 3 is processed enters first step oxidation pond, and the magnetic valve in oxidation pond at different levels UNICOM pipeline is defaulted as closing condition, and when water level reaches the elevation of water surface that Controlling System is set, magnetic valve is open-minded, makes sewage automatically drop into next stage drop type oxidation pond.In third stage oxidation pond, sewage disposal will enter second pond 5 after complete, second pond 5 adopts vertical-flow design, sterilization pool 6 adopts the disinfection way of solid chlorine tablets contact lysis, Controlling System detects the discharge of sewage according to the flow monitoring device in sterilization pool 6, control the sterilizing unit change chemical feeding quantity that can not continue according to the size of aquifer yield, reach multi-effluent and add medicine, the purpose of the few dosing of few water outlet, need other sterilizing unit to prepare separately.
Embodiment 2
As different from Example 1, the drop type oxidation pond is the level Four step-off construction, after the sewage disposal in fourth stage oxidation pond completes, will enter second pond 5.
