用滴管將聚合氯化鋁的水溶液慢慢添加到污水中，并使用玻璃棒進(jìn)行攪拌，觀察污水的絮凝效果，如果出現(xiàn)礬花就表示聚合氯化鋁的絮凝效果較好，然后將不同的量的聚合氯化鋁水溶液添加到污水的樣品中，攪拌靜置一段時(shí)間后觀察看哪個(gè)污水樣品更加干凈清澈。在使用聚合氯化鋁的過(guò)程中，有時(shí)候需要添加一些其他的助凝劑如聚丙烯酰胺等，這樣會(huì)加快污水的絮凝和沉淀達(dá)到更加好的處理效果。ties. The flocculation is deteriorated gradually with the addition of hydrolysis degree. Anionic polyacrylamide as a comprehensive result: the hydrolysis ratio is too large, the cost of adding alkali is higher, the hydrolysis ratio is too small, and the reaction will be insufficient, the coagulation or coagulation of anionic pol
用。普通情況下，50kg的水運(yùn)用1g噴霧單調(diào)型聚合氯化鋁。首先將噴霧單調(diào)型聚合氯化鋁溶于10%～30%的水溶液中，然后參與待處置水中。根據(jù)處置后水的濁度，可恰當(dāng)進(jìn)步或降低耗水量。
噴霧單調(diào)型聚合氯化鋁的產(chǎn)質(zhì)量量很多時(shí)分關(guān)系到人們的生命安康，因此，消費(fèi)噴霧單調(diào)型聚合氯化鋁具有明白而嚴(yán)厲的國(guó)度標(biāo)準(zhǔn)，可以保證人們的安康戰(zhàn)爭(zhēng)安。
滾筒式聚氯化鋁 鋁含量普通,水不溶物高,多用于污水處置.
板框式聚氯化鋁 鋁含量高， 水不溶物低. 用于污水處置和飲用處理.
噴霧單調(diào)聚氯化鋁 鋁含量高， 水不溶物低，溶解速度快，用于飲用水及更高標(biāo)準(zhǔn)水處置.
PAC聚氯化鋁由于噴霧單調(diào)穩(wěn)定性好，順應(yīng)水域?qū)挘馑俣瓤欤讲鸥蓮?qiáng)，構(gòu)成礬花大，質(zhì)密沉淀快，出水濁度低，脫水性能好等優(yōu)點(diǎn)，在同樣水質(zhì)的情況下，噴霧單調(diào)聚氯化鋁投加量減少，特別在水質(zhì)不好的情況下，噴霧單調(diào)產(chǎn)品投量與滾筒單調(diào)聚氯化鋁相比，可減少一半，不只減輕了工人的勞動(dòng)強(qiáng)度，而更重要的是減少用戶的制水本錢。除此之外，用噴霧單調(diào)產(chǎn)品可保證安全性，減少水事故，對(duì)居民飲用水非常安全可靠。When treating drinking water, polyaluminium chloride with low content will have more impurities and water insolubles, so high content is required. Especially in papermaking, cosmetics production is to use high content.
Drinking water must be treated at drinking water level. Heavy metals are not detected at industrial level, and insoluble substances in water are also higher than drinking water. Generally speaking, drinking water level is related to human life and can not be used arbitrarily. It must be a real drinking water level. If industrial level is used for drinking water, there are many hidden dangers. And the purity is different, industrial use is 26-28%, drinking water is 30%.
And sewage treatment, the content requirements are not strict, low content is not too much, you can put more medicines can also achieve the desired effect.
Henan an Jia Jing Environmental Protection Technology Co., Ltd. specializes in the production of polyaluminium chloride, which is mainly divided into drinking water level and industrial grade. The production process is mainly divided into spray method and roller method.
Drum-type polyaluminium chloride is generally used for sewage treatment because of its high water insoluble content.
Plate-frame polyaluminium chloride has high content and low water insoluble. It is used for sewage treatment and drinking treatment.
Spray drying has high content of polyaluminum chloride, low insoluble substance and fast dissolution rate. It is used for drinking water and higher standard water treatment.
PAC polyaluminium chloride has the advantages of good stability in spray drying, wide adaptation to water area, fast hydrolysis speed and strong adsorption capacity. It has the advantages of large alum, high quality and fast sedimentation, low turbidity and good dewatering performance. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially when the water quality is not good, the product volume of spray drying is compared with that of drum drying polyaluminum chloride. It can be reduced by half, which not only reduces the labor intensity of workers, but also, more importantly, reduces the cost of water production for users. In addition, spray drying products can ensure safety and reduce water accidents, which is very safe and reliable for drinking water.
