Abstract
The invention discloses an environment-friendly biological composite wastewater treatment agent with chitosan as a primary constituent. The environment-friendly biological composite wastewater treatment agent contains the chitosan, an organic flocculant and a flocculation assistant. The environment-friendly biological composite wastewater treatment agent disclosed by the invention has a good effect in treatment of terrigenous sewage, marine sewage and mariculture wastewater, can remove various pollutants so as to purify a water body efficiently, and does not cause secondary pollution.
Description
Technical field
The invention belongs to sewage treatment area, particularly a kind of environment protection biological compound sewage treatment agent take chitosan as main ingredient.
Background technology
China Lu Yuan sewage, ocean sewage and marine culture wastewater pollute very serious at present, serious such as China's coastal areas pollution, a lot of immediate offshore areas are inferior to national IV class Seawater Quality Standards substantially, belong to the severe contamination marine site, have a strong impact on peripheral quality of residents'life and shoreline, city view; And for the aquaculture water self-pollution be on the rise, disease takes place frequently, simultaneously because the impact of exogenous pollution thing, the breeding environment quality descends day by day.This not only directly works the mischief to breed variety, and the undesired water factor also is the main inducement of explosive disease frequent occurrence.
But it is unsatisfactory that the present disclosed sewage-treating agent of China is processed above-mentioned sewage effect.Adopt polyacrylamide, polyaluminium sulfate etc. such as the Lu Yuan sewage flocculant more, certain treatment effect is arranged, but certain secondary pollution but can occur; The flocculation agent that the immediate offshore area sewage disposal is adopted contain some bio-toxicities and and can cause secondary pollution; Marine culture wastewater is because the technology of the general physico-chemical method control water quality that adopts has all drawbacks, and therefore, biological control just obtains paying attention to.But generally adopting at present algae to regulate mutually with bacterium both at home and abroad regulates mutually; wherein; it is one of maximum technology of current used for aquiculture that bacterium is regulated mutually; but its operation has suitable complicacy and difficulty to control; and because these preparations can't reach the effect of effective reduction objectionable impurities; the crisis of infectivity prawn disease or prawn objectionable impurities toxinosis that lies dormant of most of high-density shrimp pond can be caused, and secondary pollution can be caused.
Sewage-treating agent is commonly used flocculation agent at present, to the research of flocculation agent, take efficient, cheapness, environmental protection as target.Environmental protection is to develop pointedly nontoxic or the low toxicity efficient flocculant, make its tap water and other relevant with physical activity with water treatment in reduce bio-toxicity and residual quantity no longer causes secondary pollution, be an important directions of from now on flocculation agent researchdevelopment.The flocculation development direction from low molecule to polymer, by inorganic to organic and microorganism, by single type to composite flocculant.Inorganic and organic polymer composite flocculant has also at home and abroad obtained carrying out widely because combining inorganic and organic advantage, become the focus of present flocculation agent research, safe, nontoxic, efficient microbial flocculant more has the trend that replaces traditional flocculant.
But still do not develop at present and a kind ofly not only can process simultaneously Lu Yuan sewage, ocean sewage and marine culture wastewater, and can not cause the sewage-treating agent of secondary pollution.
Summary of the invention
For overcoming above-mentioned technological deficiency, the invention discloses a kind of efficient, environmental protection can be simultaneously for the treatment of the environment protection biological compound sewage treatment agent of Lu Yuan sewage, ocean sewage and marine culture wastewater.
Environment protection biological compound sewage treatment agent disclosed by the invention, its main ingredient is chitosan, also contains organic floculant and flocculation auxiliary.
Described organic floculant is bodied ferric sulfate, and described flocculation auxiliary is oyster shell powder.
As solvent, by weight, contain 1～20 part of chitosan with distilled water, 5～10 parts of bodied ferric sulfates, 10～200 parts of oyster shell powders, 100～120 parts of distilled water.
Preferably, by weight, contain 5～20 parts of chitosans, 5～10 parts of bodied ferric sulfates, 50～100 parts of oyster shell powders, 100～120 parts of distilled water.
Environment protection biological compound sewage treatment agent take chitosan as main ingredient disclosed by the invention can be processed Lu Yuan sewage, ocean sewage and marine culture wastewater simultaneously, treatment effect well reaches 85% to the clearance of SS and turbidity, wherein strengthen clearance and surpass 75%, the clearance of COD is 72.5%, wherein strengthening clearance is 63.8%, the clearance of BOD5 is 56.4%, and wherein strengthening clearance is 43.5%, and strengthening effect is obvious.The COD of flocculation treatment dyeing waste water also has higher clearance, and the COD clearance of anionic dyestuff greater than 95%, is also reached more than 92% the COD clearance of other waste water from dyestuff.And the oyster shell powder in the composite flocculation agent has porousness, has simultaneously germicidal action.
