Description
Technical field
The present invention relates to technical field of sewage, especially a kind of modified domestic sewage treating compound.
Background technique
With the continuous development of industry, the usage amount of water resource also increases as, and these water resources consumed are most
All it is freshwater resources, is not suitable for the demand of industrial development using salt water resources such as seawater；But tellurian freshwater resources are very
Scarcity, 1% of accounting less than all water resources, and wherein can be by freshwater resources that the mankind directly utilize only only about
0.07%, therefore, saving water resource and recycling water resource becomes focus concerned by people, and in the recycling of water resource
In, sewage treatment is the most important thing.
Sanitary sewage is the sewage that specific gravity is increasing in present society, is produced to natural environment and human lives very big
Influence, nitrogen phosphorus, fat content in sanitary sewage higher, traditional physical method and chemical agent, often consumption is larger,
And effect is unobvious, while the addition of a large amount of chemical agent uses, and also can cause to bear to environment.For this purpose, there is researcher
Using the strains such as lactic acid bacteria, actinomyces, saccharomycete, bifidocaterium, photosynthetic bacteria, bacillus are activated respectively, expand training
Support, mixed culture obtains composite bacteria liquid, be centrifugally separating to obtain complex microorganism, complex microorganism be polyacrylamide,
Citric acid, cornstarch, breeze part, active carbon, sodium alginate are mixed into sewage-treating agent, the sewage-treating agent reaction speed
Fastly, reaction process is generated without noxious material, realizes ecology, the recycling of sanitary sewage disposal, and no longer need to set sludge
Processing system, without secondary pollution, wastewater suspended substance removal rate reaches 99.9%, BOD removal rate and reaches 99.0%, COD removal rate
Reach 99.1%, treatment effect is stablized.But due to inappropriate to raw material proportioning therein, lead to the sewage treatment obtained
The treatment effect of agent still be not up to ideal effect so that in suspended matter, BOD, COD removal effect it is undesirable, therefore, this
Researcher combines in use, appropriate adjustment is carried out to the raw material proportioning of sewage-treating agent, so as to sewage treatment
The removal rates such as BOD, COD in journey are greatly improved, and almost in having completely consumed the harmful components in sewage, improve sewage
The quality of processing provides new inorganic agent for sewage treatment field.
Summary of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of modified sanitary sewage disposal
Agent.
It is achieved particular by following technical scheme:
Modified domestic sewage treating compound, material composition are 37-45 parts of polyacrylamide, citric acid 5-8 in parts by weight
Part, 3-7 parts of active carbon, 11-18 parts of sodium alginate, 20-30 parts of Mixed Microbes；
Wherein, Mixed Microbes are by quality than actinomyces: saccharomycete: bifidocaterium: photosynthetic bacteria: bacillus=1:3:5-7:3:
4 mix.
It is preferred that the Mixed Microbes are by quality than actinomyces: saccharomycete: bifidocaterium: photosynthetic bacteria: bacillus=1:3:
6:3:4 is mixed.
It is preferred that the material composition is 41 parts of polyacrylamide, 7 parts of citric acid, 4 parts of active carbon, sea in parts by weight
16 parts of mosanom, 25 parts of Mixed Microbes.
Above-mentioned modified domestic sewage treating compound is for handling sanitary sewage, and by the temperature control of sanitary sewage
200-600mg is added according to every liter of sanitary sewage at 30-40 DEG C, by the modified domestic sewage treating compound in system, in stirring speed
Degree is 200-600r/min stir process 10-30min.
It is preferred that the modified domestic sewage treating compound additional amount is that 400mg is added according to every liter of sanitary sewage.
It is preferred that the mixing speed is 400r/min stir process 20min.
Above-mentioned modified domestic sewage treating compound preparation method, by actinomyces, saccharomycete, bifidocaterium, photosynthetic bacteria, bud
It after spore bacillus cultivates activation respectively, is inoculated on mixed culture medium and carries out mixed culture 36h, be centrifugated, obtain compound bacteria；
Compound bacteria and polyacrylamide, citric acid, active carbon, sodium alginate are cooperated according to parts by weight accounting, uniform mixing to get.
The invention is before preparation, also by mixing polyacrylamide for 1:0.5 according to mass ratio with dicyanodiamine
It is modified and then is prepared.
Compared with prior art, the technical effect of the invention is embodied in:
By choosing to material composition, control the usage amount between each material composition, reduce raw material type, reduce at
The extensive application of this higher starch etc. and coke ground-slag have the addition of pollution raw material, reduce sewage-treating agent at
This, and after the sewage-treating agent is added among sewage, it is gone so that having reached 99.8% or more, BOD to removal efficiency
Reach 99.4% or more except rate has reached 99.7% or more, COD removal rate, treatment effect is stablized, and is suitable for being widely applied.
In this researcher, also by studying the sewage-treating agent process for preparation and use process of preparation,
When sewage temperature control is 30-40 DEG C, wastewater treatment efficiency makes moderate progress, and enables to reach 99.8% to BOD removal rate
More than, COD removal rate reaches 99.6% or more, and the removal rate sack of suspended matter 99.9%.And it was further studying
Journey, the raw material after this researcher is also polluted using polyacrylamide by dicyanodiamine unintentionally is added, after making addition
BOD, COD removal rate for being formulated significantly 99.8% or more.
Specific embodiment
It is limited below with reference to specific embodiment technical solution of the present invention is further, but claimed
Range is not only limited to made description.
The modified domestic sewage treating compound being prepared in the examples below is that the temperature control of sanitary sewage exists
At 30-40 DEG C, which is added 200-600mg according to every liter of sanitary sewage, low whipping speed is
