Dimensions of construction of eye of expenditures of chloric alkaline integrated interest is Yi Dong Dongxing produce per year 400 thousand tons of pvc (among them 100 thousand tons of burnt colophony) , 600 thousand tons of 320 thousand tons of caustic soda, calcium carbide and 1 million tons of cement, it is the Nei Monggol Autonomous Region drives area to coordinate development, support the priority discipline that industry of city of cloth of Wu Lan examine upgrades.
This chloric alkaline integrated benefit produces polyvinyl chloride with calcium carbide law with the project, use technology of ionic film caustic soda, form a complete set papers colophony and plant of 3 chloric ethylene. Polyvinyl chloride is produced in calcium carbide law (in PVC) process, chloridize mercuric accelerant synthesizes chloric ethylene as acetylene and chloridize hydrogen (the activator of VCM) working procedure, loss of easy in reaction process sublimate and the generation in entering follow-up waste water contains mercuric waste water. Traditional vulcanization precipitation and activated carbon filter the system is 50ppb left and right sides commonly except mercuric effect, add mercury easy volatilize remain, make processing stability poorer, and the of nearly 20% quantity containing salt in water brings about vulcanization mercury precipitation sedimentations not easily, cause the effect that divide mercury not beautiful.
Yidongji is round east promote chemical industry and ability of division sea Cisco to sign " Yidongji is round east promote chemical pvc workshop to contain mercuric liquid waste to treat an agreement " the liquid waste that contain mercury processing project project entrusts Kehaisai, the project handles water to measure 5m³/h, enter 50μg/l of water mercuric content, kehaisai uses fiber filter + activated carbon filter + two class chela combines colophony technology, use different sulfur alcohol collaboration of chela of alternative luscious group uses the mercury in adsorptive tall brine, exert water mercuric content accomplishs 0.4μg/l.
Kehaisai regards the new and high technology that devotes oneself to innovation of environmental protection technology as the industry, answer policy of national environmental protection actively, introduce colophony of special type ion exchange home, put forward and advocate environmental protection to administer value to change a concept, to break through trade difficult problem and technical camp, undertake craft innovation and technology upgrade ceaselessly. In Yi Dong group east in promoting chemical industry to contain the item that deepness of mercuric liquid waste handles, innovation sex uses Kehaisai contain alcohol of adherent and methylic sulfur the Tulsimer®CH-97 colophony of polystyrene copolymer framework, applicable of this kind of colophony divides mercury at acidity or alkalescent liquid waste, and mercuric ionic configuration affects resinous adsorption ability scarcely, at the same time CH-97 colophony can be stabilized inside PH(0-14) limits move, through forming stable sulfur alcohol salt comes alternative purify reclaims mercuric.
Division sea thinks of deepness to divide mercuric craft besides the OK at PVC applying that contain deepness of mercuric liquid waste to administer, the deepness processing that still can apply extensively at mining to contain mercury of mercuric liquid waste and reclaim, liquid waste of the deepness processing of mercury of liquid waste of industry of electron of the deepness processing of the liquid waste mercury such as antiseptic of the deepness processing of mercury of medical industry liquid waste, agriculture insecticide, batteries, chemical industry (activator) the liquid waste that contain mercury, while the enterprise that help strength amounts to mark to arrange benefit of promotion environmental protection, reduce run cost integratedly, promote economic benefits greatly.
