Title (EN) PROCESS FOR TREATING MEDIUM-CONCENTRATION ORGANIC INDUSTRIAL WASTEWATER
(FR) PROCÉDÉ POUR LE TRAITEMENT D'EAUX USÉES INDUSTRIELLES ORGANIQUES À CONCENTRATION MOYENNE
(ZH) 中等浓度有机工业废水的处理工艺
Abstract:
(EN) A process for treating medium-concentration organic industrial wastewater, comprising the following steps: feeding raw wastewater into a conditioning tank to remove large particulate materials; then circulating the wastewater twice in an ultrasonic and hydrogen peroxide combined oxidation system and an ozone and ultraviolet combined oxidation system; and feeding the effluent of the ozone and ultraviolet combined oxidation system into a membrane filtration system, the membrane filtration system being composed of an ultrafiltration system and a reverse osmosis system, feeding the ultrafiltration produced water into the reverse osmosis system for further processing, and feeding the effluent of the reverse osmosis system into an activated carbon adsorption device, the water produced by means of the adsorption of activated carbon being reused.
(FR) Un procédé pour le traitement d'eaux usées industrielles organiques à concentration moyenne, comprenant les étapes suivantes : introduire les eaux usées brutes dans une cuve de conditionnement pour éliminer les grosses matières particulaires; puis faire circuler les eaux usées deux fois dans un système d'oxydation combiné à ultrasons et au peroxyde d'hydrogène et un système d'oxydation combiné à l'ozone et aux ultraviolets; et introduire l'effluent du système d'oxydation combiné à l'ozone et aux ultraviolets dans un système de filtration à membrane, le système de filtration à membrane étant composé d'un système d'ultrafiltration et d'un système d'osmose inverse, acheminer l'eau produite par ultrafiltration dans le système d'osmose inverse pour un traitement ultérieur, et introduire l'effluent du système d'osmose inverse dans un dispositif d'adsorption au charbon actif, l'eau produite au moyen de l'adsorption au charbon actif étant réutilisée.
(ZH) 一种中等浓度有机工业废水的处理工艺,包括如下步骤:将原始废水输入调节池,去除大颗粒物质;再将废水在超声波和双氧水组合氧化系统、臭氧和紫外线组合氧化系统中循环两次;再将臭氧和紫外线组合氧化系统的出水输入膜过滤系统,膜过滤系统由超滤系统和反渗透系统两部分组成,超滤产水进入反渗透系统进一步处理,反渗透系统的出水输入活性炭吸附装置,经活性炭吸附后的产水回用。
