PFS Coagulation Agent Application In The Processing Of Wastewater Of Tisco Coke Plant

Thesis to come together the ferric sulfate conduct and actions coagulation abent a research for handling Tisco coking plant turning waste water proceeding system, the research expresses. Throw to add in the waste water after coking plant turn steam the ammonia the iron department coagulation agent is a kind of valid liquid waste processing method with the polypropylene PAM , not only have than better result, but also the craft is simple, the expenses is cheap, can obtain the good environment performance.The research still made sure the main technique parameter, providing the theories for the actual application according to with actual applied craft parameter, give out the craft process of the liquid waste processing, and to experiment the research result proceeded the theories the analysis.The result enunciation: (1) The turns the waste water with the iron department coagulation agent a coking plant for with polypropylene PAM handling behind, through sand Filter , COD the value lowers 50% obviously, attaining 3000 mg/L or so, turn for the follow-up the series of SBR the method alleviates to carry. (2) The uses the coking plant that coagulation agent a method handles the best craft term turns waste water as:Handling a coking platn turns the waste water, throwing to add iron department coagulation agent 0.3 ml, mix blend strength as 120 rpm, mix blend time as 120 s, join coagulation a polypropylene PAM 0.6 ml, mix blend time as 60 s, sink to decline time as 20 min, the value of pH is about 9.Handles with the coagulation agent a method the coking plant turn the waste water, covering the area small, invest little, operate the management simple.Economic costsxoking plant that handles the ï¿¥ 1.01/t in an expenses in medicine turns the waste water.
