Abstract
The invention provides a design method and an operating process for an unpowered buoyancy-type decanter for a sequencing batch reactor activated sludge process (SBR) biological treatment system. The decanter consists of a float, a connecting rib plate, a water decanting barrel, a rotatable link 1, a flow guiding pipe, a rotatable water decanting pipe, a rotatable link 2, a wall drain pipe, a sewer valve, a drain valve, and a support. The water decanting operation comprises two steps of sludge discharge and water discharge. Through the adjustment and change of the operating process and the design method for the conventional buoyancy-type decanter, the disadvantage of necessarily lifting the conventional buoyancy-type decanter over the water surface during the aeration is overcome; moreover, through the improvement on the appearance design of the parts of the buoyancy-type decanter, such as the float, the water decanting barrel and the like, the stability of the device is improved and the manufacturing and maintenance costs of the device are reduced.
Description
Technical field
The present invention relates to a kind of SBR biological treatment system with design and the operating procedure thereof of straining hydrophone, relate in particular to a kind of unpowered buoyancy-type and strain hydrophone design and its operating procedure.
Background technology
(Sequencing Batch Reactor Activated Sludge Process SBR) is a kind of active sludge sewage disposal technology that moves by the intermittent aeration mode to the sequence intermittent activated sludge process.Different with traditional waste water treatment process, the operating method of the alternative space segmentation of operating method that the SBR technology employing time is cut apart, astable biochemical reaction substitutes the stable state biochemical reaction, leaves standstill desirable precipitation and substitutes traditional dynamic precipitation.The sbr reactor pond collects homogenizing, heavy, biological degradation just, two functions such as heavy in a pond, no mud return-flow system.SBR handle have that the biochemical reaction impellent is big, efficient is high, anaerobism, the aerobic alternating state that is in the pond, good purification, operating performance are stable, anti impulsion load, flexible operation, simple structure, be convenient to advantage such as operation and maintenance management, can also effectively control activated sludge bulking, be the preferred treatment process of Industrial Wastewater Treatment of middle small town sewage and industrial enterprise.
Because SBR treating pond design feature, its water-freeing arrangement and other wastewater treatment forms have very big difference, and according to domestic and international report, SBR handles draining and mainly is divided into submersible pump formula, multiple spot drainage type and strains the hydrophone formula.Wherein straining hydrophone is present most widely used drainage pattern.Straining hydrophone can be divided into rotary-type water decanter, cover skeleton symbol on the type and strain hydrophone, siphonic decant device, floating skeleton symbol and strain hydrophone, pump formula and strain hydrophone, membrane type and strain hydrophone, can regulate flexible tubular and strain hydrophone etc.
Summary of the invention
The present invention handles in conjunction with SBR and strains the hydrophone work characteristics, change operating procedure and the method for design that the conventional pontoon formula is strained hydrophone by adjusting, overcoming traditional floatage-type strains hydrophone and needs lifting leave water surface shortcoming during aeration, simultaneously by floatage-type being strained the improvement of member profile designs such as hydrophone floating drum, receipts water drum, be intended to improve stabilization of equipment performance, reduce device fabrication and maintenance cost.
The present invention strains hydrophone and is made up of floating drum, connection gusset, receipts bucket, rotatable connection 1, thrust-augmenting nozzle, rotatable receipts water pipe, rotatable connection 2, water shoot through walls, wash water valve, water discharge valve, support, strains the water operation and comprises blowdown mud, two steps of draining.The floating drum that the present invention uses is annular floating drum, and annular floating drum helps to stablize, and the buoyancy unanimity that annular floating drum all directions provide phenomenon can not occur laying particular stress on, so more stable.Floating drum part submerged, a part surfaces, and self is provided and receives bucket buoyancy, and water outlet enters the receipts bucket through upper reaches, floating drum bottom when straining water, and floating drum can play the scum silica frost effect of blocking again simultaneously.Receive bucket all the time below the water surface, be installed in the floating drum in the ring, floating drum links to each other by connecting gusset with receiving between the bucket, and evenly perforate on the gusset connects by changing different holes, can regulate the entry of receipts bucket highly, thereby can regulate receipts (straining) water speed.Receiving bucket links to each other with thrust-augmenting nozzle by rotatable connection 1, rotatable connection 1 can be rotated when bucket height and position change with floating drum receiving, regulate the angle of receiving between bucket and the thrust-augmenting nozzle, make the receipts bucket be in horizontality all the time, to guarantee to receive the homogeneity of water.The thrust-augmenting nozzle the other end is by flange or be solder-connected on the rotatable receipts water pipe, and drives rotatable receipts water pipe turn to correct position when float-level height and change in location.For improving drainability and stability, thrust-augmenting nozzle is generally two, and comes rotatable receipts water pipe vertical direction.Rotatable receipts water pipe and water shoot through walls combine by rotatable connection 2, and the water shoot the other end through walls pond outside part is equipped with water discharge valve and wash water valve.Support is used for supporting and stablizing rotatable receipts water pipe.
Straining the water operation is divided into spoil disposal, strains two steps of water.The spoil disposal purpose is to discharge non-bleeding stage to enter the mud of receiving in water drum, thrust-augmenting nozzle, rotatable receipts water pipe and the water shoot through walls, and any workshop section all could before the mud of discharge entered the SBR processing by curb.After going out clarification of water, close sewage draining valve, open water discharging valve and strain water operation, strain water and finish to close flowing water Valve, can regulate and strain water speed by regulating the water discharge valve switch size.The Long-distance Control drainage procedure can use internally piloted valve with wash water valve and water discharge valve.
The present invention strains hydrophone can be applied widely according to water displacement, strains outlet capacity at 25-500m
3Engineering between the/h uses the single hydrophone of straining just can satisfy and strain the water needs.Drainage speed surpasses 500m
3Can strain the hydrophone number by increase during/h realizes.The present invention strains hydrophone and strains the water operation applicable to various SBR processing.
Beneficial effect of the present invention and remarkable advantage:
The characteristics of straining the hydrophone maximum that the present invention is designed are in operating process such as aeration, water inlet, strain hydrophone receipts bucket and need not hang the water surface, realized real unpowered, in operating process such as water inlet, aeration, enter the materials of straining in the waterpipe such as mud and straining in the water process, can not influence and strain quality by the emptying of spoil disposal process.In addition, the employed floating drum of the design is annular floating drum, and buoyancy is good, though floating at the water surface in aeration process, because phenomenon can not appear overturning in annular floating drum satisfactory stability.Strain water speed and can regulate flexible operation by the water discharging valve size.Strain water operation by change in addition, saved the power set that the conventional pontoon formula is strained hydrophone, so the design greatly reduces cost and maintenance, cost of use.
