Description
Technical field
The utility model relates to a kind of opel oxidation ditch internal reflux system for sewage disposal, especially a kind of opel oxidation ditch internal reflux system residual sea water pump locating mechanism.
Background technology
The opel oxidation ditch system is a kind of Sewage treatment systems, and it is used for implementing Orbal oxidation ditch process, belongs to the extended aeration process in the activated sludge process.The ditch body of opel oxidation ditch is comprised of three concentration ellipsis shape raceway grooves usually, and sewage is entered by outer raceway groove with after returned sluge mixes, and enters successively middle ditch and septal fossula, and tens of to hundreds of times at each raceway groove internal recycle, final outflow water is to second pond.The rotary disk aerator that quantity does not wait is installed, to carry out oxygenation and plug-flow stirring action in each raceway groove.
Compare with common oxidation ditch, the opel oxidation ditch can be regarded a kind of multi-stage oxidizing ditch by outer fissure, middle ditch and septal fossula series connection as.The function of outer raceway groove mainly is efficiently to finish carbon source oxidation, denitrification and most of nitrated, volume accounts for 50%～55% of oxidation ditch volume usually, can remove the organism about 80%, dissolved oxygen concentration is generally between 0mg/l～0.5mg/l, in raceway groove, form alternately oxygen consumption and large regional anaerobic environment, but higher degree ground carries out " nitrification and denitrification " simultaneously, and denitrification effect is obvious, and the clearance of ammonia nitrogen can be up to 90%; Simultaneously, because most of regional dissolved oxygen is between 0mg/l～0.5mg/l in the raceway groove, the oxygen transfer function carries out under the oxygen deficit condition, and the transfer rate of oxygen increases, and energy-saving effect is obvious.Middle raceway groove is the transition section of contact outer fissure and septal fossula, carrying out complementation regulates, further remove remaining organism and continue to finish Ammonia Nitrification, and can give full play to the strengthening effect of outer raceway groove or interior raceway groove, be conducive to guarantee system's reliability of operation, middle raceway groove volume generally accounts for 25%～30%, and Dissolved Oxygen concentration Control is about 1.0mg/l.Interior raceway groove mainly is in order to ensure the oxidation ditch effluent quality, and dissolved oxygen concentration to guarantee organism and the higher clearance of ammonia nitrogen, guarantees that simultaneously water outlet enters second pond with enough dissolved oxygens about about 2.0mg/l, suppress phosphate releasing.Interior raceway groove volume accounts for 15%～20% of oxidation ditch cubic capacity.
The sewage disposal company at applicant place has namely adopted the opel oxidation ditch system to carry out sewage disposal.But the applicant in use finds, during cold operation, the nitration reaction effect is relatively poor in the outer fissure, has affected COD, TN and NH in the winter time
3-N removal effect causes effluent quality unstable.If increase aerator to improve the outer fissure dissolved oxygen amount at outer fissure, then easily destroy existing layout, and can increase higher equipment cost.
In order to address the above problem, the applicant considers a kind of opel oxidation ditch internal reflux system can be set, adopt residual sea water pump and pipeline with the sewage backflow of septal fossula in outer fissure, can improve outer fissure nitration reaction effect, to address the above problem.But this system is when arranging, how to make things convenient for residual sea water pump in septal fossula maintenance examination and avoid residual sea water pump to be washed away by current, becoming needs to consider the problem that solves.
The utility model content
For the deficiencies in the prior art, technical problem to be solved in the utility model is how to provide a kind of simple in structure, the opel oxidation ditch internal reflux system residual sea water pump locating mechanism that can make things convenient for the residual sea water pump maintenance examination and avoid these current of residual sea water pump to wash away.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of opel oxidation ditch internal reflux system residual sea water pump locating mechanism, it is characterized in that, the residual sea water pump locating mechanism comprises and lifts guide rail, lifts support and rope, the described guide rail that lifts vertically is arranged on the septal fossula furrow bank, described residual sea water pump can slide up and down to be socketed in and lift on the guide rail, lifting support is fixedly installed on the septal fossula ditch that lifts guide rail top and is provided with fixed pulley on the bank and lifting support, described rope one end is fixed on the residual sea water pump, and the other end is upwards walked around the fixed pulley that lifts on the support and is fixed to the septal fossula ditch on the bank under backward.
Mainly by lifting guide rail, lifting support and rope consists of, simple in structure, implementation cost is cheap for the utility model, is convenient to realize.After having adopted this locating mechanism, when residual sea water pump needs repairing when checking, can spur rope, residual sea water pump successfully can be risen to the water surface and carries out maintenance examination along lifting guide rail.After finishing, maintenance examination send to lift guide rail and residual sea water pump is put back in the water get final product, and very convenient fast with laborsaving.Lift simultaneously guide rail and can realize location to residual sea water pump, guarantee that residual sea water pump can not washed away by current.
Therefore, the utlity model has simple in structurely, be convenient to implement the advantage that can make things convenient for the residual sea water pump maintenance examination and avoid these current of residual sea water pump to wash away.
