Description
Technical field
The present invention relates to flocculant, specifically a kind of heavy metal-polluted water process flocculant.
Background technology
Have the heavy metals such as many copper, iron, zinc, magnesium in sewage, they or be dissolved in sewage, or be suspended in sewage
In；
Traditional effluent purification method is to first pass through filtering or flocculate, the suspended material removal in sewage, then again with activity
Sludge, water spray is considered the microbial treatment methods such as bed process, anaerobism and is made a return journey except the dissolved matter in sewage；Removal suspended material one
As the flocculant selected be aluminum sulfate, ferric sulfate, the inorganic flocculating agent such as ferrous sulfate, or polypropylene phthalein amine, aluminium polychloride
Deng high polymer coagulant；These flocculants can effectively remove the suspended material in sewage, but can not remove deliquescent
Pollutant；
Deliquescent pollutant can be removed with the method for microorganism, but microbial treatment method has limitation very much, it is necessary to adjust
The conditions such as section pH, temperature, dissolved oxygen amount；Also, polluter is the nutrient of microorganism, and the amount of nutrient is excessive all can shadow or very few
Ring the purified treatment ability of microorganism；Other salt content or the excessive sewage of oil content will also result in microbiological treatment rate drop
It is low, it is necessary to pre-process；In order to maintain these treatment conditions, microbial treatment method needs adjustment tank, aeration tank, stillpot,
The equipment such as sludge send-back system, digestive shelf；In order to install these equipment, it is necessary to very big floor space；
Microbiological treatment needs the various operating costs such as medicament expense, personal services, the electricity charge and cost of investment higher in a word；
Although can remove the heavy metal of a part using the microbiological treatment of activated sludge process, the sludge for producing still can shine into
Secondary pollution problems.
