Abstract
The utility model provides a formula fenton reaction device is criticized to preface for current fenton reaction device adds the dose inaccuracy because structural defect makes service condition heavy handled when solving urine volume engineering advanced treatment, goes out the unstable problem of water. A formula fenton reaction device is criticized to preface includes: the cone retort, the inlet tube, the mud pipe, the drain pipe, agitator etc. Fenton reaction preface wholesale goes on, adds various medicaments behind the full water of retort respectively to stir the reaction, reaction back totally is quiet heavy, and the flocculation object precipitates the awl bottom, discharges qualified water, and the operation of one -period is accomplished to back row mud, waits for next period run.
Description
Technical field
The utility model relates to the conventional further treatment technique field of sewage treatment industry, refer to that COD of sewage is difficult to degraded especially, and water outlet requires high, the engineering that the process water yield is little.
Background technology
Sewage is after biochemical treatment, can almost be completely degraded by biodegradable organic pollutant, bio-chemical effluent COD still can not meet water quality reaching standard requirement, now, the biochemical of water outlet is poor, in water, rest COD is difficult to utilize biological degradation, for ensureing standard water discharge, the method for chemical dosing (Strong oxdiative) need be adopted to carry out advanced treatment further.
Fenton's reaction mechanism:
1893, chemist FentonHJ finds, hydrogen peroxide (H2O2) has strong oxidizing property with the mixing solutions of ferrous ion Fe, can by organic compound much known at that time as carboxylic acid, alcohol, ester class are oxidized to inorganic states, and oxidation effectiveness is very remarkable.People have employed a chemical equation more extensively quoted to describe the chemical reaction occurred in Fenton reagent:
Fe+H2O2→Fe+OH+·OH
The Fe of 1mol is generated after the Fe reaction of H2O2 and the 1mol of 1mol, simultaneously with the OH generating 1mol, the hydroxyl radical free radical of additional 1mol.The existence of hydroxyl radical free radical just, makes Fenton reagent have strong oxidation capacity.According to calculating in the solution of pH=4, the oxidation potential of hydroxyl radical free radical is up to 2.73V.
Reaction structures:
PH on-line computing model is set in Fenton's reaction pond, add hydrochloric acid soln, when adding H2O2 solution and copperas solution according to certain dosing ratio in reaction tank during reaction environment pH=4 in pond, stir simultaneously, liquid caustic soda furnishing is added neutral after having reacted, add PAM flocculation again, quiet heavy after discharge clear water.
Along with Fenton technology popularization application, occur some new problems, for the project of the industry big yields such as papermaking, Fenton technology continuously-running, each dosing unit independently separately, enters post precipitation unit after Fenton's reaction.But for the engineering of some little water yields, water is discontinuous, chemical feeding quantity is difficult to control, and effluent quality extremely unstable, this sequence batch (Fenton's reaction device solves this problem.
Utility model content
The utility model proposes a kind of sequence batch (Fenton's reaction device, during for solving little water yield engineering advanced treatment, existing Fenton's reaction device is due to structural defect, and make operational conditions be difficult to control, chemical feeding quantity out of true, goes out the problem of water unstable.
The technical solution of the utility model is achieved in that
A kind of sequence batch (Fenton's reaction device, comprising:
PR tank, tank body can be circle also can be square, and bottom must be taper, is convenient to spoil disposal;
