Brief description of the drawings
Fig. 1 is the oil refining sewerage biological treatment device schematic flow sheet of invention.
Specific embodiment
Structural principle of the invention and operation principle are described in detail below in conjunction with the accompanying drawings:
Can realize that Biodegradability of Wastewater is higher, COD clearances are high it is an object of the invention to provide one kind,
Sewage can qualified discharge oil refining sewerage biological treatment device.
The oil refining sewerage biological treatment device, the device includes the hydrolysis acidification unit, the aeration list that are sequentially connected
Unit, primary deposition unit, LINPOR units and final precipitation unit.
Hydrolysis acidification unit in the oil refining sewerage biological treatment device is a hydrolysis acidification reaction tank, hydrolysis
Acidizing Process Technique is to be subject to a kind of improved sewage disinfection treatment technology on the basis of anaerobic technology, of the invention
The treatment water of hydrolysis acidification pool is 300m3/ h, the size of hydrolysis acidification pool is 31.5m × 10m × 5.5m,
Effective liquid level of hydrolysis acidification pool is 5.1m, and the dischargeable capacity of hydrolysis acidification pool is 1530m3, sewage exists
The hydrolysis acidification pool residence time is 5.1h.Due to hydrolysis acidification reaction tank, to be belonging to upflow anaerobic sludge blanket process anti-
The technology category of device is answered, multiple injection well downhole flow regulators are provided with hydrolysis acidification reaction tank, a diameter of 1m of injection well downhole flow regulator matches somebody with somebody
Hydrophone quantity is 15, and water distribution uses pressure type water dispensing apparatus.Sewage by hydrolysis acidification reaction tank bottom
Into by Sludge Bed, the particulate matter and colloidal substance in water inlet are retained rapidly and inhaled by a large amount of microorganisms
Attached, this is a fast reaction for physical process, general only to need to complete within several seconds to tens seconds, is cut
The material for leaving is adsorbed on the surface of Sludge Bed, because these materials are attracted to Sludge Bed surface, so
Residence time in device is greater than hydraulic detention time, and be decomposed metabolism at leisure.Largely hydrolyzing micro- life
By insoluble hydrolysis of organic matter into solable matter in the presence of thing, while under the synergy of acid-producing bacteria
By macromolecular substances, it is difficult to degradable chemical and is converted into the small-molecule substance that is readily biodegradable, releases again
It is put into liquid, enters in postorder handling process with sewage.Because microorganism is while degradation of organic substances,
Increase breeding with organic matter as what substrate carried out itself, can make the sludge quantity of hydrolysis unit increases, thus will
This amount of activated sludge enters sludge condensation and dewatering unit.In this course, dissolubility BOD, CO
Although the clearance of D is anecdotally very low, hydrolysis acid is increased because particulate organic matter occurs hydrolysis
Change the concentration of dissolved organic matter in cell arrangement, therefore, dissolubility BOD, COD clearance is actually
It is very high.Hydrolysis acidification method of the invention be it is a kind of between method aerobic and between Anaerobic Treatment method, it is and straight
Anaerobic Treatment is connect to compare, it is short with hydraulic detention time, the advantages of floor space is small;With direct Aerobic Process for Treatment
Compare, have the advantages that Biodegradability of Wastewater energy, strong shock resistance can be improved.Hydrolysis acidification reaction tank collection
, in one, organic matter is in hydrolysis acidification reaction tank for precipitation, absorption, bioflocculation, biological degradation function
Removal includes physics, chemical and biochemical combined reaction process, i.e., using hydrolysis and acid-producing microorganisms,
By the solid in sewage, macromolecular and to be difficult biodegradable organic matter degradation be readily biodegradable small point
Sub- organic matter so that sewage is obtained with less energy consumption and under the shorter residence time in follow-up aerobic unit
Treatment.
Aeration unit in the oil refining sewerage biological treatment device, aeration unit is a pure oxygen aeration pond, and this is pure

Sludge, because the partial pressure of oxygen in pure oxygen aeration is big, the rate of transform is high, makes that high concentration can be kept in aeration tank
Dissolved oxygen and high sludge concentration, therefore pure oxygen aeration pool volume is small, and floor space is small.And pure oxygen aeration
The oxygen for being used is air separation unit accessory substance, if do not utilized, is then processed by emptying, wastes the energy, and
Energy consumption and operating cost for can then reduce purified water herein.Meanwhile, from pure oxygen aeration petrochemical industry at home
From the point of view of the practical situations of enterprise, its treatment effeciency is high, impact resistance is good, it is stable the characteristics of
Confirmed.The treatment water in pure oxygen aeration pond is 600m3/ h, each closed pond pond body size is
15.6m × 15.6m × 6m, effective liquid level in each closed pond is 4.4m, three total effective appearances in closed pond
Product is 3210m3, sewage is 6h in the aeration unit residence time, and the activated sludge of unit mass is in unit
It is 0.3kgBOD/ [kgMLVSSd] for volumetric loading is that the amount of interior removed pollutant is sludge loading
1.8kgBOD/m3.d, concentration of suspension is 6000mg/L, and sludge is 5.3h in the aeration unit residence time,
Oxygen demand is 1.45kgO2/ kgBOD, sludge output is the dry mud/kgBOD of 0.4kg, return sludge ratio:100%.
LINPOR units in the oil refining sewerage biological treatment device, LINPOR units are a LINPOR
Oxidation pond, LINPOR oxidation ponds use a kind of technology similar with contact oxidation technology, and the technique is
Based on the principle of original sewage-treatment plant aerator active microorganism, by special porous polyurethane filler
Insert in aeration tank, porous polyurethane filler is stopped by the filter of particular design in pond.LINPOR oxidation ponds
Bottom is provided with aerator, and air is provided for it by air blower, activated sludge on porous polyurethane filler surface and
Growth inside, and grown in the form of suspension flco, the activated sludge of fixed growth and suspension growth is always dense
Degree is about the twice of traditional activated sludge process sludge concentration, and organic loading also increases about 34%, so that complete
Into biological denitrificaion and carbonization treatment.The LINPOR oxidation ponds are using the life being attached on porous polyurethane filler
Thing film processes pollutant.The porous polyurethane filler is spongy block, and size is
1.5cm × 1.5cm × 1.2cm, with very big specific surface area, make can be kept in LINPOR oxidation ponds compared with
Biomass high and abundant microbial population, are particularly conducive to breed the life of generation time microorganism long
It is long, such as remove the nitrifier of ammonia nitrogen and the flora of decomposition hardly degraded organic substance.LINPOR oxidation ponds also have
It is not easily blocked, the characteristics of without backwashing, and is provided with extruding demoulding pump, porous polyurethane filler is through squeezing
After the extruding of pressure-off membrane pump, the renewal of biomembrane is accelerated, and improves bioactivity.LINPOR oxidation technologies exist
