Abstract
The invention discloses a kind of carbon source sustained release agent for Biological Treatment of Wastewater, the mass percent proportioning of its constituent is：Molasses 10 50%；Starch 15 50%；Sustained release agent 10 35%；Releasing agent 2 10%.The present invention need to be only put into waste water, easy to use, while can be used according to actual conditions, can flexibly grasp the speed of carbon source release, and product stability and long shelf-life of the invention, required raw material sources are extensive, and cost is cheap, be adapted to industrialized production.
Description
Technical field
The invention belongs to technical field of waste water processing, specifically, more particularly to it is a kind of for Biological Treatment of Wastewater
Carbon source sustained release agent.
Background technology
During Biological Treatment of Wastewater, due to the influence of shortage and the noxious material accumulation of nutriment so that raw
Micro organism quantity in thing method processing waste water system is reduced, and performance degradation, influences water treatment effect.It therefore meets these bacterium
The growth of group needs, and the vigor for improving or keeping them is very important measure.
Chinese invention patent CN104386829B discloses a kind of microbial nutrition synergy suitable for treatment of dyeing wastewater
Agent, its shortcoming one be nutritional ingredient based on glucose, cost is higher；Second, the synergist is water base, if for largely useless
Water treatment stage, easily cause nutrition and be quickly lost in failure and waste.Chinese patent CN103641202B discloses a kind of for seeking
Support the suspending type biological degraded adsorption tower of unbalance organic wastewater with difficult degradation thereby processing, its shortcoming be by sorbent material slow-release nitrogen and
Phosphorus, though improving nutrient imbalance, waste water is the increase in nitrogen and the processing load of phosphorus, once processing release is not good at, is added
Water eutrophication risk.
The content of the invention
The technical problem to be solved in the present invention is to overcome drawbacks described above, there is provided a kind of carbon for Biological Treatment of Wastewater
Source sustained release agent, the sustained release agent is easy to use, and cost is cheap, and microorganism can be directly high using carbon source content, and long-acting can slowly release
Carbon source grows for system microorganism and maintains vigor, suitable for promoting.
To solve the above problems, the technical solution adopted in the present invention is：
A kind of carbon source sustained release agent for Biological Treatment of Wastewater, it is characterised in that：The mass percent of its constituent
Match and be：
Molasses 10-50%；
Starch 15-50%；
Sustained release agent 10-35%；
Releasing agent 2-10%.
Meanwhile present invention also offers another carbon source sustained release agent for being used for Biological Treatment of Wastewater, it is characterised in that：Its
The mass percent of constituent matches：
Molasses 40-50%；
Starch 30-40%；
Sustained release agent 5-15%；
Releasing agent 5-10%.
As a kind of technical scheme of optimization, the molasses be in cane molasses, beet molasses and grape molasses at least
It is a kind of.
As a kind of technical scheme of optimization, the starch be in porous-starch, gelatinized starch and common starch at least
It is a kind of.
As a kind of technical scheme of optimization, the sustained release agent is polyalkylene glycol monoalkyl ether and fatty acid ethylene glycol ether fat
At least one of.
As a kind of technical scheme of optimization, the releasing agent is stearate, microcrystalline cellulose and hydroxyethyl cellulose
At least one of.
By adopting the above-described technical solution, compared with prior art, the present invention need to be only put into waste water, easy to use,
It can be used simultaneously according to actual conditions, can flexibly grasp the speed of carbon source release, product stability of the invention and shelf-life
Long, required raw material sources are extensive, and cost is cheap, are adapted to industrialized production.
Embodiment
Embodiment：
A kind of carbon source sustained release agent for Biological Treatment of Wastewater, the mass percent proportioning of its constituent are：40%
Molasses, 35% starch, 15% sustained release agent, releasing agent 10%.
Wherein, the molasses are beet molasses, the sugar content highest in current molasses, and more based on sucrose.The shallow lake
Powder is the mixture that 50% porous-starch and 50% gelatinized starch form, and the better of bonding is realized in such ratio mixing, main
It is used to adsorb molasses and granulation.The sustained release agent is 50% polyalkylene glycol monoalkyl ether and 50% fatty acid ethylene glycol ether fat group
Into mixture, be mainly used in carbon source sustained release.The releasing agent is stearate, is mainly used in threshing.
The sustained release agent of the present invention is mainly characterized in that required raw material sources are extensive, and cost is cheap, is adapted to industrialized production.And
It is easy to use, product stability and long shelf-life.Suitable for the sewage disposal that all kinds of nutrient imbalances, particularly carbon source are unbalance, together
When in terms of soil remediation also huge applications potentiality.
The present invention is not limited to above-mentioned preferred embodiment, and anyone should learn that what is made under the enlightenment of the present invention
Structure change, it is every with it is of the invention have it is same or similar as technical scheme, belong to protection scope of the present invention.
