些企氯化鋁一般情況下,從外觀上就能夠看出來,分褐色,土黃色,黃色,淡黃色和白色。褐色的聚合氯化鋁屬于低檔,土黃色聚合氯化鋁屬于中檔產(chǎn)品,黃色和白色的都屬于高檔次的產(chǎn)品。價格依次增長。
價格也不同

對854個鄉(xiāng)鎮(zhèn)進(jìn)行調(diào)查,每天的排放量達(dá)365.3億噸.其間工業(yè)廢水達(dá)成協(xié)議5.5億噸. 這些廢水絕大部分未經(jīng)處理就直接排放, 污染了江河湖海. 水污染的危害是不是顯而易見的.水體污染,水質(zhì)惡化對人體健康和人類日子,出產(chǎn)都帶來了嚴(yán)重的危害. Over the years, polyaluminium chloride has developed into a flocculant with mature technology and large market sales, and has gradually replaced the traditional flocculant. Western European countries began
to produce polyaluminium chloride as flocculant for industrial sewage treatment in 1976, and the United States and Canada approved its use in urban water supply and industrial sewage treatment in 1983. Polyaluminium chloride (PAC) is a commonly used coagulant in water treatment. Its water treatment effect is remarkable, and it plays an important role in drinking water and industrial sewage purification. The content of polyaluminium chloride is 26%, 28% and 30%. The content of polyaluminium chloride is different, the use is different, and the corresponding price of polyaluminium chloride is also different.
It is obvious that polyaluminium chloride (PAC) can manage water pollution reasonably.
The state has investigated 854 townships and villages, with a daily discharge of 36.53 billion tons. In the meantime, an agreement has been reached on 550 million tons of industrial wastewater. Most of these wastewater is discharged directly without treatment and pollutes rivers, lakes and seas. Is the harm of water pollution obvious? Water pollution and deterioration of water quality have brought serious harm to human health and human life and production?
When green and turbulent forests are replaced by endless desert and yellow dust, white clouds floating carelessly in the blue sky are replaced by rolling black smoke, and the ozone layer that shelters the earth from wind and rain is damaged by relentless Freon, I can bly hear the cries of forests, the sorrow of white clouds and the sigh of the ozone layer.
The demand of polyaluminium chloride flocculants at home and abroad is increasing rapidly. Especially in water treatment, the traditional flocculants have been gradually replaced by polyaluminium chloride flocculants and become mainstream flocculants. A large number of application practices have proved that the use of polychlorination rate instead of traditional iron and aluminium salt coagulants can significantly improve the purification efficiency of water plants, reduce the cost of treatment, and improve the quality of effluent. Polyaluminium chloride is used as purifier for daily drinking water and industrial sewage (such as oily sewage, printing and dyeing sewage, paper-making sewage, etc.). In addition, it is also widely used in fine casting, paper making and leather making. The effect of high turbidity water is particularly obvious; without alkaline additives or other coagulant aids, i
t is suitable for wide water quality, fast and large alum comb, high quality, easy sedimentation, high safety of clean water, low corrosiveness and low labor intensity of workers.
It produces high-efficiency polyaluminium chloride, high-efficiency aluminium ferric chloride, high-efficiency polyferric sulfate, high-efficiency basic aluminium chloride, polyacrylamide (yin, yang, non-ionic), activated carbon and various filter materials. The products are widely used in domestic water companies, mines, paper-making
