一所西班牙大學(xué)開發(fā)了一個廢水處理站的有機處理微污染物的系統(tǒng)。這個系統(tǒng)使用木素降解酶和納米過濾陶瓷膜來保持系統(tǒng)的酵素。能夠用于處理藥物制造、農(nóng)藥、化妝品、焚燒阻滯劑、激素以及其他化工產(chǎn)品的微污染物。該大學(xué)希望與工業(yè)廢水處理公司達(dá)成許可證協(xié)議合作。
Summary:
A Spanish university developed a micropollutant removal system for waste-water treatment plants. It consists in using lignolytic enzymes combined with nanofiltration/ultrafiltration ceramic membrane to retain the enzyme in the system. It’s aimed to be used in plants treating pharmaceuticals, pesticides, cosmetics, flame retardants, hormones or other industrial chemicals. The university is interested in a license agreement with waste-water treatment companies specialized in industrial chemicals.
Details:
The discharge into the aquatic environment of organic micropollutants from wastewater treatment plants is a major environmental problem due to the possible adverse effects that these chemicals have on animals, plants and people. Among these micropollutants a group of substances of natural and anthropogenic sources (e.g pharmaceuticals, pesticides, cosmetics and personal care products, flame retardants, hormones and other industrial chemicals) have the ability to alter the functions of endocrine system and, therefore, adverse effects on an organism or its progeny. Conventional systems for wastewater treatment are not designed to remove these compounds, or their removal is only partial, causing a continuous release of such chemicals to the environment.
This new technology is adapted to remove these kind of microprollutants in wastewater treatments plants thanks to the use of lignolytic enzymes combined with the use of a nanofiltration or ultrafiltration ceramic membrane that retain the enzymes in the system.
The experiments carried out in bench scale reactors have shown very good results as more than 80 % of bisphenol A (BPA) and more than 97 % of nonylphenol (NP) present in the influent were removed.
Type and Role of Partners Sought:
The university would like to find an industrial partner dedicated to the treatment of wastewater containing industrial chemicals that would be interested in license the technology.
