Abstract
The invention discloses a kind of using chitosan as the environment protection biological compound sewage inorganic agent of key component, contain chitosan, organic flocculant and flocculation aid.Environment protection biological compound sewage inorganic agent disclosed by the invention handles Lu Yuan sewage, ocean sewage and marine culture wastewater and works well, and can remove various pollutants, water body is made to obtain high-efficient purification, and will not generate secondary pollution.
Description
Technical field
It is more particularly to a kind of compound using chitosan as the environment protection biological of key component the invention belongs to sewage treatment field
Sewage-treating agent.
Background technology
China Lu Yuan sewage, ocean sewage and marine culture wastewater pollution are very serious at present, such as China's coastal areas pollution
Seriously, many immediate offshore areas are inferior to national IV classes sea water quality standard substantially, belong to serious pollution marine site, seriously affect periphery residence
People's quality of life and city coastline landscape；And for breeding water body self-pollution is on the rise, disease takes place frequently, simultaneously because outside
The influence of source contact scar object, breeding environment quality increasingly decline.This not only directly damages to breed variety, but also bad water
Prime factor is also the main inducement that explosive disease frequently occurs.
But it is unsatisfactory that the presently disclosed sewage-treating agent in China handles above-mentioned sewage effect.As Lu Yuan sewage flocculants are more
Using polyacrylamide, polyaluminium sulfate etc., there is certain treatment effect, but be present with certain secondary pollution；Offshore
The flocculant that marine site sewage disposal uses contains some bio-toxicities and and can cause secondary pollution；Marine culture wastewater is due to one
As the technology of used physico-chemical method control water quality have a variety of drawbacks, therefore, BIOLOGICAL CONTROL is just paid attention to.But current state
Inside and outside general mutually adjusted using algae is mutually adjusted with bacterium, wherein, it is one of current most technology used for aquiculture that bacterium, which is mutually adjusted,
But it, which is operated, has comparable complexity and difficulty to control, and effectively reduces harmful substance since these preparations are unable to reach
Effect can cause most of high density shrimp ponds to lie dormant the crisis of infectiousness prawn disease or prawn harmful substance nosotoxicosis, and meeting
Cause secondary pollution.
Sewage-treating agent is often with flocculant, the research to flocculant, with efficient, cheap, environmentally friendly for target at present.Environmental protection is
Nontoxic or less toxic efficient flocculant is pointedly developed, makes it in drinking water and other use water process related with physical activity
It reduces bio-toxicity and residual quantity no longer causes secondary pollution, be an important directions of flocculant research and development from now on.Flocculation
Agent developing direction from low molecule to macromolecule, by it is inorganic to organic and microorganism, by single type to composite flocculant.It is inorganic and
Organic polymer composite flocculant has also at home and abroad obtained extensive development because combining the advantages of inorganic and organic, into
For the hot spot of current flocculant research, the trend of safe and nontoxic, the efficient more substituted traditional flocculant of microbial flocculant.
But still do not develop at present a kind of can not only handle Lu Yuan sewage, ocean sewage and sea-farming and give up simultaneously
Water, and the sewage-treating agent of secondary pollution will not be caused.
The content of the invention
To overcome above-mentioned technological deficiency, the invention discloses it is a kind of efficiently, environmental protection can be used for simultaneously handle Lu Yuan dirt
The environment protection biological compound sewage inorganic agent of water, ocean sewage and marine culture wastewater.
Environment protection biological compound sewage inorganic agent disclosed by the invention, key component are chitosans, also containing organic wadding
Solidifying agent and flocculation aid.
The organic flocculant is bodied ferric sulfate, and the flocculation aid is oyster shell powder.
By the use of distilled water as solvent, by weight, contain 1~20 part of chitosan, 5~10 parts of bodied ferric sulfate, oyster shell powder
10~200 parts, 100~120 parts of distilled water.
Preferably, by weight, containing 5~20 parts of chitosan, 5~10 parts of bodied ferric sulfate, 50~100 parts of oyster shell powder,
100~120 parts of distilled water.
Environment protection biological compound sewage inorganic agent disclosed by the invention using chitosan as key component can be handled simultaneously
Lu Yuan sewage, ocean sewage and marine culture wastewater, treatment effect well to the removal rate of SS and turbidity up to 85%, wherein strengthening
Removal rate of the removal rate more than 75%, COD is 72.5%, wherein the removal rate that reinforcing removal rate is 63.8%, BOD5 is
56.4%, wherein it is 43.5% to strengthen removal rate, strengthen with obvious effects.The COD of flocculation treatment dyeing waste water also has higher go
Except rate, 95% is more than to the COD removal rates of anionic dyes, to the COD removal rates of other waste water from dyestuff also up to more than 92%.
And the oyster shell powder in composite flocculation agent has porosity, while there is bactericidal effect.
Specific embodiment
It below will the present invention is described in detail by specific embodiment.
Embodiment 1：
5 parts of chitosan, 10 parts of bodied ferric sulfate, 50 parts of oyster shell powder, 120 parts of distilled water.
Embodiment 2：
20 parts of chitosan, 10 parts of bodied ferric sulfate, 200 parts of oyster shell powder, 120 parts of distilled water.
Embodiment 3：
10 parts of chitosan, 8 parts of bodied ferric sulfate, 50 parts of oyster shell powder, 100 parts of distilled water.
Implement 4：
5 parts of chitosan, 10 parts of bodied ferric sulfate, 50 parts of oyster shell powder, 100 parts of distilled water.
Embodiment 5：
Sewage is carried out to Shenzhen great Chan gulfs sewage water body to environment protection biological compound sewage inorganic agent prepared by embodiment 1-4
It administers, specific method is：Pick up from the black foul sewage water before 10-11 months big shovel gulf flood tide.Water intaking adds in multiple to 50kg drums on the spot
Flocculant is closed, injected volume can be 0.5ppm-1000ppm.In the present embodiment injected volume be respectively 0.5ppm, 10ppm, 50ppm,
