摘要： Proposed is a process for collecting and removing microplastics in wastewater. The process includes coagulating microplastics in wastewater and adding an enzyme to the coagulated microplastics. Also, a method for collecting and removing microplastics is provided, the process comprising: pulverizing polyethylene terephthalate (PET) bottles into microplastics; dispersing the microplastics into a water system; coagulating the microplastics to produce coagulated microplastics; and adding an enzyme to the coagulated microplastics whereby the coagulated microplastics are decomposed by the enzyme into their monomer constituents. According to this process and method, the microplastics in wastewater can be removed with high efficiency.

摘要： The invention relates to the methods for sewage treatment contaminated by mechanical impurities, fats, proteins and other organic and inorganic compounds, and can be used for purification and water disinfection contaminated by heavy and radioactive metals, saturated or unsaturated fats, filtrate from landfills, meat processing plants, and/or oil and petroleum. The method includes flotation, electrocoagulation and filtration, and provides: mixing water with carbon-based sorbent; filtration of water and carbon sorbent on rubber-based hydrophobic sorbent; decomposition of organic substances accumulated on carbon and rubber sorbents; floatation with hydrogen peroxide; recovery active substance in hydrogen peroxide; reuse thereof; electrocoagulation with water saturation with oxygen and hydrogen, formed on indispensable carbon or metal electrodes based on the of aluminum, titanium, sodium, tin, copper, and other metals; water disinfection by electro-cavitation; generation of active substance based on the iron and titanium atoms; water filtration on the precoat filter; and filtering on activated carbon filter.
