A kind of sewage-treating agent for sugar industry wastewater
Technical field
The present invention relates to a kind of sewage-treating agent, especially relate to a kind of sewage-treating agent for sugar industry wastewater.
Background technology
In the production process of sugar enterprise, a lot of waste water can be produced, because organism is more in these waste water, as some disaccharide or polysaccharide, due to organic existence, result in chemical oxygen demand and biological oxygen consumption value in the factory effluent of sugar enterprise all higher, if these pollutents are without suitable process, directly be disposed in environment, easily cause the eutrophication of water body, welding.Therefore before discharging, need to process the factory effluent of sugar enterprise, reduce biology consumption oxygen consumption value wherein and biochemical oxygen demand value.
Effective especially sewage-treating agent for sugar industry wastewater process is still immature at present, how to seek a kind of sewage-treating agent for sugar industry wastewater feature efficiently with low cost, is a problem being worth research.
Summary of the invention
Goal of the invention: bad in order to solve sugar industry wastewater normal treatment process effect existing in prior art, specially the problem of effect treatment agent shortage, the present invention proposes a kind of sewage-treating agent for sugar industry wastewater efficient, with low cost.
Technical scheme: to achieve these objectives, the present invention takes following technical scheme:
A kind of sewage-treating agent for sugar industry wastewater, its working conditions is under anaerobic to use, and comprise following component by weight: 10-20 part coal ash, 15-20 part gac, 10-20 part plant rod fiber, 5-10 part polyacrylamide, 10-20 part titanium dioxide granule, 5-10 part amine bacillus, 5-15 part acidophilic bacteria, 15-20 part discoloring agent, 10-15 part Alteromonad, 10-15 part photosynthetic bacteria group, all containing being not less than 2.0 hundred million active bacteria in monoxenic every gram of substratum.
In order to ensure that gac has good adsorption effect, specific surface area is large, and described gac is grain diameter is 6-12 order.
Further, described plant rod fiber be selected from kaoliang stalk, corn stalk, cotton stem, rice straw one or more, coarse-fibred plant rod fiber is more conducive to the high organic degraded of sugar production wastewater.
Further, described polyacrylamide is powdered polypropylene acid amides or zwitter-ion polyacrylamide.
Further, described discoloring agent is dehydrated alcohol, anhydrous magnesium sulfate, diatomite three mass ratio be the mixture of 1:1:2.
Further, described titanium dioxide granule is loading nano-titania particle.
Further, described photosynthetic bacteria group is purple nonsulfur bacteria.
Beneficial effect: a kind of sewage-treating agent for sugar industry wastewater provided by the invention, according to the characteristic of sugar industry wastewater, under the processing mode of anaerobism, select suitable chemistry and biological treatment agent to be optimized combination, each microorganism in its process of growth, produce useful matter and secretory product forms the matrix and raw material that mutually grow, and by mutual symbiosis, it is complicated that Relationship With Proliferation forms a composition, Stability Analysis of Structures, function has the microflora of varied bacterium widely, be aided with the synergy of chemical treatment medicament again, mutual reciprocity and mutual benefit in the scavenging process of sugar industry wastewater, play the associating advantage that it is maximum, there is efficient treatment effect, make discharged wastewater met the national standard, and it is with low cost, remarkable in economical benefits.
