Abstract
The invention discloses an oxidization coagulant for treating coking wastewater, which consists of two parts of an oxidization flocculant and a coagulant aid. The oxidization flocculant comprises the following components according to proportion by weight: 8-20% of flocculant polyferric sulfate, 0.1-2.0% of oxidant ferrate and the balance of water; and the coagulant aid is polyacrylamide aqueous solution. In the invention, the double functions of oxidization and flocculation are available, the removal rate of the coking wastewater CODcr (Chemical Oxygen Demand) can reach more than 70%, the draining water is clear, the colority is less than 80 times, the adding amount is little, and the cost is low, wherein the medicament cost of advanced treatment is only 0.5 RMB/ton; the condition is easy to control and the operation is convenient. The invention provides an economical and efficient method and powerful assurances for the draining standard of advanced treatment of the coking wastewater.
Description
Technical field
The present invention relates to a kind of water conditioner, specifically a kind of to coking chemical waste water process biochemical treatment section, behind the arrival second pond, carry out physico-chemical process and handle the oxidization coagulant that uses.
Background technology
The coking chemical waste water pollutent is formed complicated, the compounds such as aromatic series organism, polynuclear compound and oxygen sulphur nitrogen that contain volatile phenol and many difficult degradations, be a kind of typical unmanageable organic industrial sewage, so the processing of coking chemical waste water is a great problem of domestic and international wastewater treatment always.Domestic each coking chemical waste water enterprise adopts biochemical process in conjunction with the physico-chemical process Treatment of Wastewater in Coking more at present, and physico-chemical process is that the single bodied ferric sulfate of employing is that coagulating agent is to the COD in the bio-chemical effluent
Cr, suspended substance, colourity further remove, but its dosage is big, and under the high dosage condition of coagulating agent COD
CrRemoval efficient still undesirable, and general to the removal effect of suspended substance, colourity, water outlet can't stably reaching standard.Recently have and use the report that the Fenton-coagulating agent is handled again, its COD that degrades
CrEffective, but the cost height of Fenton-coagulating agent, condition control difficulty is big.
Summary of the invention
The object of the present invention is to provide a kind of oxidization coagulant, to realize COD
CrRemoval efficient height, to the removal effect ideal of suspended substance, colourity, make the stable water outlet after the processing up to standard, and the processing cost and simple to operate, the condition that can reduce coking chemical waste water are greatly controlled easily.
Oxidization coagulant of the present invention is made of oxidizing flocculant and coagulant aids two portions, and described oxidizing flocculant is made of following component and weight ratio: flocculant poly ferric sulfate 8～20%, and oxygenant ferrate 0.1～2.0%, surplus are water; Described coagulant aids is 0.1～0.3% polyacrylamide solution.
Comprise oxidative decoloration agent 11% clorox 5～30% in the described oxidizing flocculant.
Described ferrate is Na2Fe04 or potassium ferrate.
The present invention has the double effects of oxidation and flocculation, the oxygenant ferrate of selecting for use or the mixture of ferrate and clorox, it has outstanding advantage for poisonous in the treating water, bio-refractory aspect, adopt again nontoxic flocculant poly ferric sulfate it have that floc particle is big, sedimentation is fast, the compression dehydration property is strong, adapt to characteristics such as water pH value amplitude broad, and be not subjected to the influence of water temperature, increased organic coagulant aids again, thereby cohesion speed is faster, and the present invention is COD not only
CrRemoval effect is obvious, and colourity is had bigger removal, coking chemical waste water COD
CrClearance can reach more than 70%, go out clarification of water, colourity is below 80 times, its dosage is little, cost is low, the advanced treatment reagent cost only is 0.5 yuan/ton; And condition controls easily, easy to operate; The method and the strong assurance of economical and efficient are provided for the coking wastewater deep treatment water outlet is up to standard.
