Abstract

The invention relates to the field of mariculture wastewater treatment and discloses a mariculture wastewater treatment system which comprises a water inlet area, a pollution reduction area and a water outlet area. Iron-carbon filler is added into the whole treatment system; the filler not only can be used as a micro electrode to improve the current density and conductivity, but also can be used as a carrier for attachment of microorganisms; meanwhile, iron in the iron-carbon filler accelerates reduction in the wastewater; Fe < 2 + > and Fe < 3 + > generated by the reaction react with complexation in the wastewater to form precipitates, so that dephosphorization is realized. That is, the physical, chemical and biological combined method is adopted, so that the wastewater treatment effect is improved; meanwhile, the hydrogen ions are generated on the surface of the cathode of the electrolysis device, a part of natural alkalinity in the mariculture wastewater can be neutralized, the alkalinity can be controlled within a proper range, and the operation cost is saved; in addition, the cathode of the electrolysis device reacts to generate HClO which has a certain effect of killing pathogenic bacteria, and the HClO oxidizes the nitrides in the wastewater to generate nitrogen, so that denitrification is realized.

Description

technical field [0001] The invention relates to the field of mariculture wastewater treatment, in particular to a treatment system and method for mariculture wastewater. Background technique [0002] At present, with the continuous development of the economy, people's demand for seafood is increasing day by day. In order to meet this supply and demand, the marine aquaculture along the coast of our country mostly increases the breeding density to increase the production, which leads to a large amount of residual bait and feces. Discharge into the water body will lead to a sharp increase in the nitrogen and phosphorus content in the aquaculture pond water, resulting in eutrophication of seawater. This not only deteriorates the aquaculture environment, but also produces aquaculture tail water that will have a bad impact on the water quality of the coastal waters and the marine ecological environment, and even cause frequent red tides. Therefore, mariculture wastewater must be ...
