Description
Technical field
The utility model relates to a kind of field of environment pollution control, particularly a kind of device based on seawater cell technology, nutrient discovery in marine culture wastewater being become magnesium ammonium phosphate.
Background technology
In recent years, China's mariculture industry development rapidly, cultured output occupies first place in the world for years, also make marine culture wastewater total emission volumn more than Lu Yuan total amount of sewage discharge simultaneously, refuse main in marine culture wastewater has residual bait, movement, chemical substance and curative drug remain, the dead volume of aquaculture organism and pathogenic agent are also parts for refuse, thus after breeding wastewater discharges in a large number, make nitrogen in ocean water body, the nutritive substances such as phosphorus sharply increase, cause aquaculture water and vicinity waters eutrophication or water quality deterioration, Aquaculture ecosystem can be caused time serious unbalance, disorderly and even collapse completely.When this water body has suitable biology, the hydrology and meteorological conditions, even red tide may be produced.
Marine culture wastewater is compared with sanitary sewage with trade effluent, marine culture wastewater has two obvious features, namely the content of potential pollutant is low large with the water yield, due to the effect of salinity of seawater and the singularity of marine culture wastewater pollution structure, adds the intractability of breeding wastewater.At present, domestic and international marine culture wastewater mainly contains several classes such as physics, chemistry, biology.Physical method filters with settling tank precipitation, sand filter and with zeolite powder absorption, the impurity in water and dirt removed, but not good to the removal effect of dissolved organic matter, inorganics and total N, P etc.; The marine culture wastewater chemical treatment method comparatively early used, as although the improver of water quality such as copper sulfate, chlorinated lime, malachite green also can carry out certain process to the waste water after cultivation, but because these methods can produce secondary pollution to environment, and some methods also can damage human body, prohibit the use now; Applying more in current marine culture wastewater biochemical treatment is the techniques such as bio-contact oxidation, blodisc, biological fluidized bed, have compared with materialization technology invest low, not easily produce the advantages such as secondary pollution, but due to the effect of salinity of breeding wastewater, make the biophase overall metabolic selectivity in these techniques and effective microbe ratio lower, the unit volume processing load of system is not high, and treatment cycle is longer.
Seawater cell is that general reference is using seawater as electrolytical battery.Generally refer in ocean environment using seawater as electrolytical chemical power source.It relies on anode metal material corrosion dissolution in the seawater to provide anode discharge electric current, negative electrode then mainly relies on dissolved oxygen of seawater on noble electrode, carry out reduction reaction and provides cathodic current, the anode material of successful Application in high-power seawater cell concentrates on magnesium alloy and aluminium alloy, this mainly has due to magnesium, aluminium the anode performance being better than other metals, as electropotential is negative, density is little, specific storage is high.Marine culture wastewater belongs to high concentration salt solutions, both containing the Na that seawater component is main
