Problems solved by technology
However, it has the disadvantage of being easy to pollute. At present, in the process of seawater treatment, membrane fouling mainly comes from organic, inorganic and particulate matter. The main ways to solve membrane fouling include membrane cleaning, innovation of membrane materials and optimization of membrane treatment process.

Abstract
The invention relates to a treatment device and process for marine aquaculture wastewater. According to the technical problems of membrane pollution in the membrane treatment process of marine aquaculture wastewater, starting from two aspects of process and membrane material, primary filtration is used to remove wastewater before membrane treatment The particulate matter in the waste water is then sent to the coupling device of compressed air and electrochemical reaction device to remove most of the nitrogen-containing compounds and organic volatile substances in the waste water, reducing the growth of bacteria and the formation of organic colloids in the waste water. inhibition of membrane fouling. In addition, by blending 3-aminopropyltriethoxysilane-modified nano-titanium dioxide in the polysulfone membrane, the polysulfone membrane layer is modified with a dialdehyde acid solution to form a grafted intermediate layer, and then a hydrophilic and The bactericidal polyethylenimine complexed with copper not only increases the antibacterial properties of the membrane but also improves the treatment flux of the membrane. The marine aquaculture wastewater treatment process in the present invention can reach the standard after the marine wastewater is treated, and is a long-lasting process with good treatment effect.
Description
technical field [0001] The invention relates to a process for treating marine aquaculture wastewater, in particular to a process for treating marine aquaculture wastewater with a membrane method. Background technique [0002] In recent years, people's living standards have been greatly improved, and the demand for nutrients is also increasing. Mariculture has developed rapidly, but more and more aquaculture wastewater has been produced. Mariculture wastewater mainly contains pollutants such as suspended particles, organic matter, ammonia nitrogen, nitrite, nitrate, and phosphate. Improper treatment will aggravate the degree of eutrophication in coastal waters, and mariculture wastewater has high salinity effects. There are many problems such as large displacement, few special technologies, and inability to directly use freshwater aquaculture wastewater treatment technology. Therefore, reasonable and efficient treatment of mariculture wastewater is one of the current research...
