Description
Technical field
The present invention relates to provide biological treatment to the dirty waste water of load organic substance.
International classification number of the present invention is: C12F3/10, C121/00, C02F3/30, C02F11/04, C02C1/04, C02F3/28.
Background technology
Selected anaerobic treatment is the method for implementing under the cool condition having a liking for.This method also is not used in the conventional processing station.This processing can be purified liquid waste, and does not use any electric energy, heat energy or other energy.
The structure of this equipment can optionally be realized the different residence times according to the solid sediment, fat, colloid and the soluble material that are derived from waste water.The speed of these times and its anaerobically fermenting is proportional.In addition, also have a kind of being used under the condition that does not almost have hydraulic pressure, implement the solution of biofiltration, this solution can more easily be removed the gas as the bacterial activity byproduct.
Of the present invention open
Generally, three kinds of methods are arranged in sewage and Industrial Wastewater Treatment:
1. in pulp digester and methane-generating pit, carry out anaerobic treatment.This method is more blunt, and many shortcomings are arranged.It can carry out the purification of low degree, has the long residence time, and this time has surpassed 28 days.In addition, fund input is huge.
2. based on the mode of oxygen dissolution in water, aerobic system is divided into several types.We think following several system known per:
A) carry out surface aeration by turbine and brush.
B) have deep aeration big and little bubble, wherein adopted compressor and gas blower etc.
C) the anti-stream natural aeration of use filler.
3. aerobic-anaerobism facultative or round-robin handle, this realizes by disk.These all methods have a common characteristic: oxidation in aerobic method, in the anaerobism method, reduce.In both cases, the decomposition of organic materials (refuse material) realizes that by bacterium this has just formed microbial film on solid platform.
Mass transfer launches at this microbial film in water from bacterium or the bacterial metabolism.In microbial film formation, the aerobic or anaerobic digestion of organic substance has been arranged.These microbial films form on fixing or buoyant is surperficial.
The anaerobism method realizes in pulp digester or methane-generating pit, the development of very importantly floating surface (biological activity sludge), if it does not reach best concentration, then this method is invalid.
The maintenance of the constant density of sludge is quite long and complicated process in substratum.
On the other hand, because the variation of different parameters, these methods are highstrung, and described parameter is: organic loading, pH, temperature, redox potential, anaerobism degree, CO
2The existence of concentration, inhibitor, the hydraulic pressure of substratum and air pressure and normal atmosphere thereof.
Anaerobically fermenting is to the dependency of such multiparameter, makes that it is very expensive, efficient is lower and longer duration.
The outward appearance of the system of tool fixed biofilm (French Patent No.8102266/1981 and No.8024427/1980) is for realizing that anaerobically fermenting presents metabolism condition preferably.Yet preliminary examination shows on its textural and function and lacks greatly, though this idea is a progressive.
A kind of anaerobic biological reactor that has little hydraulic pressure and air pressure and have fixed biofilm has been described in my patent No.44552 (Belgrade 1990).On this bio-reactor, make great efforts to have obtained success, more better than the bio-reactor of routine.(residence time, from 3,5 to 6 hours, the generation of biogas was up to 11m
3/ m
3Every day, degree of purification surpasses 95%).
In this described invention, the real meaning of active surface has been proposed first, as the zone of realizing biological respinse, and dissidently with other people be: the volume of bio-reactor, they think that this is a crucial factor of bio-reactor validity.
These suppositions will be used to purify the basis of the new treatment station of dirty waste water with organic loading and other waste water as structure.
Explanation of the present invention
See from accompanying drawing that as us a treatment station that is used for sewage is arranged, be made up of two portions: anaerobism settler (I) and anaerobe strainer (II), they have constituted an entity.The anaerobism settler is made up of a columnar lidded container, has conical bottom, the retainer (3) of floating substance vertical shifting is guided and made to the fluid of inlet pipe (1) and (2), elementary anaerobe strainer has big settler (7), based on the end with holes (6), the funnel (8) that is used for emptied of water, the extension tube (9) that is connected with secondary biofilter (II).
Secondary biofilter (II) is made up of round shape container and bottom with cover, wherein based on several pallets (10), fills up with filter material.This pallet has annular fence (barrier) (15) and overflow port (11), (12).Biofilter has import (9), outlet (12) and is used for the outlet of biogas (14).
The function at anaerobic treatment station
Take settler through the preliminary waste water that obtains that filters of coarse and meticulous mechanical impurity to by pipe (1) and (2).Sedimentable matter falls, and is deposited on this conical bottom; It is removed once in two to three weeks by pipe (4) and (5).
Contain the liter waterborne of floating substance (fat, Mierocrystalline cellulose, colloid and soluble material), and reach elementary biofilter (7).Conical fence (3) has just been held back floating substance, and has distributed water equably, by the whole surface of settler.
In elementary biofilter, floating substance is trapped, and realizes hydrophilization.The water that has passed through this biofilter just contains soluble and the colloidal organic substance so that in secondary biofilter (II) by germ attack.
This biofilter of creating has little hydraulic pressure (140mmH when work
2O) and air pressure (normal atmosphere), its objective is the byproduct of removing biological respinse, biological example biogas.
In the anaerobism settler, and in secondary biofilter, water moves freely.Translational speed by filter material must be in forming biomembranous speed limit scope.Water by dropping on the lower pallet down after the filter material, and carries out same moving with annular movement (referring to cross section a-a), but in the opposite direction, all pallets on by biofilter.
The volume of selected material and its active surface are proportional, and depend on the organic loading of water.
According to COD (chemical oxygen demand (COD)), the resolution of organic materials can reach 75 to 95% value.
Embodiment: have the anaerobic treatment station of 150P.E. ability, have following characteristics:
-hydraulic load----------22.5m
3/ day
-organic materials load---------9kg BOD 5/ day
-size:
-diameter--------------3000mm
---------------3060mm highly
This settler, primary and secondary biofilter are arranged in a cylindrical vessel
The degree of purification of-expectation---------be higher than 95% (according to COD)
------------is lower than 30mg/l to-suspended matter
-this treatment station is adjusted to and is used for dirty wastewater treatment.Need the hydraulic pressure drop to be higher than 1mH
2O.This treatment station is closed and places underground.On the next door of this treatment station, there is a pond to be used for stablizing sludge, this pond was drained once in per 6 months.And the water that enters treatment station must filter from the fence of coarse (25mm) and meticulous (10mm).
The industry using method
This treatment station can be used to the to load sewage and the Industrial Wastewater Treatment of organic substance.Before entering treatment station, by using the fence of 16mm and 10mm, water has to filter from mechanical impurity.
A large amount of inhibitor is microbiotic, phenol, solid metal etc. for example, and treatment station is constituted a threat to.
For concentration, suggestion is not higher than 2000mg/l according to COD (chemical oxygen demand (COD)).
Note observing the temperature of water inlet, and be stabilized in the scope of having a liking for cold or middle temperature (mezophilic).
This treatment station is made by ordinary steel, and this ordinary steel must protectedly not weather.
This treatment station preferably is located at underground, but still can build on the ground, if build on the ground then need to carry out heat insulation processing.
