Description
Technical field
The present invention relates to a kind of use in waste water treatment catalyst.
Background technique
In traditional anaerobic-aerobic biological respinse, biology is consumed by metabolism provides the pollution of nutrition in water body
Ingredient.Aerobic condition is with O2As electron donor, anaerobic condition is with reduction-state S or Fe or biomass agent and granulating
Active particle be electron transmission.
In traditional processing method, PH is adjusted, the organism in temperature stirring, granular sludge and biofacies is given birth to
Object redox, equal confined condition is more, and under traditional tupe, in order to inhibit water body to be poisoned, common method is to pass through
Increase the residence time and reinforce power consumption come what is realized, is such as changed using increasing aeration quantity or returning the methods of stream
It is kind, it is also possible to oxygen poisoning or certain pollution factors and load is caused to can not achieve effective processing etc. in some conditions to ask
Topic.
Summary of the invention
The technical problem to be solved by the present invention is to biological respinse in existing sewage treatment, time-consuming, power consumption is big.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: sewage treatment catalyst, the catalyst are served as reasons
Moulding component, catalyst component and adjust component according to the ratio, at a temperature of 1000 DEG C -1400 DEG C be sintered made of catalyst granules；
The moulding component uses the bamboo carbon powder of 60-80 mesh；The catalyst component includes nickel nitrate, manganese, copper, ferric nitrate；The tune
It saves component and uses diatomite or resin particle；The mass ratio of the moulding component, catalyst component and adjusting component is 3 ~ 4: 6 ~ 7:
2~6；Nickel nitrate in the catalyst component, manganese, copper, ferric nitrate mass ratio be 0.02 ~ 0.03: 0.4 ~ 1.1:1.1 ~ 1.3:2 ~
4。
The purposes of moulding component is easy for forming, and the effect of catalyst component is the reaction for increasing antimicrobial surface and forming metabolism
Speed, the effect for adjusting component is the solids specific gravity for adjusting catalyst, different according to sewage quality, it is sometimes necessary to urge
Agent is kept afloat, it is sometimes desirable to be sunk under water, or as water flow is floated, it is however generally that, when need solids specific gravity compared with
When big, using diatomite, when needing solids specific gravity smaller, using resin particle.When handling sewage, with traditional wastewater
Processing method is compared, and after catalyst granules of the invention is added in sewage, 64%-76% is can be improved in aerobic reaction speed, is detested
Oxygen reaction speed improves 55%-83%, substantially reduces the residence time in waste water control, improves the efficiency for administering sewage,
Further, since catalyst granules will not catalyst fines be like that as water flow is flushed away as, not only due to can make repeatedly
With and reduce use cost, nor can as typical catalyst powder to water flow generate secondary pollution.
It further, further include accelerating component particle, the acceleration component particle includes anthraquinone and active carbon particle, passes through work
Property charcoal granular absorption solidify anthraquinone, until active carbon particle adsorption saturation；It is pressed by moulding component, catalyst component and adjusting component
Catalyst granules made of proportion sintering is uniformly mixed with component particle is accelerated；The acceleration component particle and catalyst particles
The mass ratio of grain is 1.2 ~ 3:8 ~ 16.Anthraquinone can further speed up the reaction speed of catalyst granules, but due to anthraquinone itself
Be easy to volatilize decomposition, and is not easy to be firmly combined with catalyst granules made of sintering, and therefore, it is necessary to individually be located with active carbon
Reason, is mixed in proportion the active carbon particle for adhering to enough anthraquinones together with catalyst granules made of sintering by room temperature
It comes into operation.Anthraquinone is neither influenced in this way to play a role, and anthraquinone can be firmly attached to the surface of active carbon particle, Bu Huisui
Water flow is lost, and convenient for reaching primary dispensing, the effect of Reusability, and anthraquinone will not be lost with water flow, avoided and caused anthracene
Secondary pollution of the quinone to water.
The invention has the advantages that biological respinse time-consuming is short, power consumption is small, reusable and effect stability.
