Abstract
The utility model relates to an oxidation reaction tower for water treatment used for removing soluble heavy metal ion in raw water or industrial waste water, comprising a tower body, a reaction center pipe, etc. The utility model is characterized in that the lower part of the reaction center pipe is communicated with a neutralizing agent juice filling pipe, a raw water or waste water inlet pipe and an air lance. The utility model has the advantages that the consumption of the neutralizing agent is reduced, the removal ratio of the soluble heavy metal ion in water is enhanced, iron and manganese ion contents in the water are lower than 1 and 0.1 mg / l after treatment, and removal ratio is 98-100%.
Description
The utility model relates to the water treating equipment of heavy metal ion in former water of a kind of water treating equipment, particularly oxidation removal or the trade effluent.
Contain soluble iron, manganese plasma in the former water, influence civilian or the industrial production use.Contain a large amount of these type of heavy metal ion in non-ferrous metal metallurgy, iron and steel, titanium dioxide, the detergent factory's trade effluent.Must can discharge or reuse through handling.Adopt present general equipment such as flow lifting type expansion neutralizing tower, drum-type filtration neutralizer to remove soluble heavy metal ions in former water or the waste water, its common shortcoming is that clearance is low, removal of heavy metal ions rate as trade effluent has only about 50%, is difficult to reach the basic demand of water treatment.
The purpose of this utility model provides the water treating equipment of soluble heavy metal ions in former water of a kind of efficient removal or the waste water.
Task of the present utility model is finished like this.Inject the neutralizing agent juice in former water or the trade effluent, regulate pH value, make water transfer alkali to by acidity, spray into air simultaneously, the assurance oxidizing reaction is fully carried out in vigorous stirring, at a low price becomes after oxidation can settled high-valency metal compound for soluble metal ion, through promptly be purified water behind settling tank eliminating settling.The utility model of principle design one-tenth is made up of tower body and reactive center pipe etc. in view of the above.The reactive center pipe is positioned at tower body central authorities, is communicated with neutralizing agent juice filler pipe, former water or waste water in reactive center pipe bottom and enters pipe, air lance, also can only be communicated with back two kinds of pipelines.Neutralizing agent juice filler pipe, former water or waste water enter pipe can be radially or tangentially be communicated with the reactive center pipe.The tower body bottom has scum pipe, top that effluent trough, rising pipe are arranged.There is the reflection flow deflector reactive center pipe upper end, also has extraction hood.Between tower body and extraction hood, form the particle separation chamber.Between reactive center pipe outer wall and tower body inwall, form reaction chamber.Because feed the effect of reactive center pipe airflow, oxidizing reaction from bottom to top, is carried out again in reactive center pipe and reaction chamber from top to bottom repeatedly.Discharge from scum pipe after the inert substance sedimentation.Generate and to be gathered in tower body top by settled high volence metal ion compound through oxidation, flow out from rising pipe through effluent trough, after neutralizing treatment enters settling tank, be excluded, be purified water immediately with current.
Fig. 1 is the utility model water treatment oxidizing reaction tower sectional view
Now the utility model is described in further detail in conjunction with the accompanying drawings.
The utility model is made up of tower body (12), reactive center pipe (7) etc.Reactive center pipe (7) is positioned at tower body (12) central authorities, supports (5) by means of pipe core and fuses with tower body (12).Reactive center pipe (7) both ends open, bottom are communicated with neutralizing agent juice filler pipe (8), former water or waste water and enter pipe (11), air lance (9), also can only be communicated with back two kinds of pipelines.It can be radially or tangentially to be communicated with reactive center pipe (7) that neutralizing agent juice filler pipe (8), former water or waste water enter pipe (11).The tower body bottom has scum pipe (10), top that effluent trough (14), rising pipe (2) are arranged.There is reflection flow deflector (4) reactive center pipe (7) upper end, also has extraction hood (1).Between tower body (12) and extraction hood (1), form particle separation chamber (3).Between reactive center pipe (7) and tower body (12) inner chamber, form reaction chamber (6).Tower body (12) is provided with maintenance open holes (13).
The neutralizing agent of using is lime or carbide slag, can also can directly add in the tower body reaction chamber (6) through neutralizing agent juice filler pipe (8) input reactive center pipe (7).PH value generally is adjusted into 8-10.Because the effect of airflow, oxidizing reaction is fully carried out in the reactive center pipe He in the tower body reaction chamber, both saved the consumption of neutralizing agent, improve the clearance of former water or trade effluent soluble heavy metal ions again, through the utility model handle and after settling tank is handled water outlet iron, mn ion content be lower than 1,0.1 mg/litre, clearance is at 98-100%.
Claims (4)
