Description
Technical field
This utility model belongs to waste water harmless treatment field, is specifically related in a kind of quick elimination waste water the device of residual hydrogen peroxide.
Background technology
In recent years, along with the development of China's economic level and improving constantly of society's level, people are day by day strong to the protection demand of environmental conservation especially water body environment.But, the use of the novel organic additive of a large amount of synthetic significantly increases the intractability of relevant waste water on the one hand, pollutant emission standard day by day harsh on the other hand also forces the production activity of each industrial undertaking to be had difficulty in walking, for COD, its emission limit oneself be low to moderate the level of 50mg/L, some provincial standard is lower.Therefore, how utilizing existing green technology to properly settle this difficult problem is the powerful guarantee that China's economy develops in a healthy way at a high speed.
The high-level oxidation technology being representative with Fenton oxidation, has played huge effect in the improvement of polluted-water since self-discovery.Its principle is in acid condition, hydrogen peroxide H2O2Molecule is at Fe2+The catalytic action of ion produces oxidability and is only second to F2Hydroxyl radical free radical (OH), OH can destroy in water body the molecular structure of most organic pollutions, makes contaminant molecule permineralization or molecular structure thoroughly change.Therefore, utilize the water inlet of this technical finesse biochemical system can significantly improve the biodegradability of target waste water, improve the COD removal efficiency of wastewater biochemical water outlet.Additionally, this technology also can be widely used to the advanced treating of the COD biochemical system still exceeded standard or chemical system water outlet and the qualified discharge of tail water.
Although Fenton's reaction has played huge effect in wastewater treatment, but its Related Technical Issues faced also cannot be avoided, for instance, usual Fenton's reaction carries out under being acid condition, the pH value of waste water is 2～4, and Fenton's reaction still remains substantial amounts of hydrogen peroxide (H after terminating in water body2O2) molecule, because of H2O2There is the effect of sterilization, the biological activity of microorganism in biochemical system is not only seriously suppressed to make system biochemical efficiency reduce, part COD also can be contributed to cause the COD value virtual height of water outlet, and the bubble that its last decomposition produces can cause serious mud phenomenon to cause mud-water separation difficulty.Research shows, 1mgH2O2Molecule can produce the COD of about 4mg, is therefore highly desirable to eliminate H superfluous after Fenton's reaction terminates2O2Molecule.
Summary of the invention
The purpose of this utility model is for solving an above-mentioned difficult problem, it is proposed that the device of residual hydrogen peroxide in a kind of quick elimination waste water.
The technical solution of the utility model is achieved through the following technical solutions:
The device of residual hydrogen peroxide in a kind of quick elimination waste water, including being arranged in order the preconditioning pond of setting, reaction tank and solid-liquid separation tank, described reaction tank shares a pool wall with preconditioning pond, solid-liquid separation tank respectively, the pool wall top shared in described reaction tank and preconditioning pond is provided with the first outlet, the pool wall top shared at described reaction tank and solid-liquid separation tank is provided with the second outlet, and the height of the first described outlet is higher than the height of the second outlet to realize the depth displacement overflow of waste water；Being provided with pH meter and agitator in described preconditioning pond, described preconditioning pond is connected with dosing tank；The bottom of described reaction tank is provided with gas distribution pipe, and gas distribution pipe connects with aerator through air inlet pipe；The bottom of described solid-liquid separation tank is provided with solid-liquid separation valve.
Preferably, the described preconditioning pond connecting line with dosing tank is provided with dosing pump.
Preferably, the first described outlet exceeds the second outlet 5cm.
This utility model device is adopted quickly to eliminate the method for residual hydrogen peroxide in waste water: pH value initially enters preconditioning pond at the former water of acid Fenton oxidation of 2～4, alkali liquor is added through dosing tank by the control of pH meter, pH value of waste water is regulated to 8～9 under the stirring of agitator, now namely Fenton's reaction terminates, and preconditioning process terminates；Waste water after pH regulator is by depth displacement overflow to reaction tank, through aerator, air is delivered to gas distribution pipe, under the stirring of bubble and carrying dual function secretly, in waste water, the hydrogen peroxide molecule of residual starts accelerated decomposition, decompose the bubble produced to overflow from water body rapidly, do not have mud scum to occur to reaction tank, when overflowing also without minute bubbles, illustrate that peroxide decomposition is complete；Waste water is again through depth displacement overflow to solid-liquid separation tank, suspended solid in waste water sinks under gravity bottom solid-liquid separation tank, it is deposited on the precipitation bottom solid-liquid separation tank and discharges solid-liquid separation tank through solid-liquid separation valve, supernatant is discharged into next unit from the outlet at solid-liquid separation tank top, and now solid-liquid separation process terminates；In this spent process water, the hydrogen peroxide molecule of residual can be removed completely, subsequent processes will not be produced impact.
The beneficial effects of the utility model:
This utility model apparatus structure is simple, adopts this device to process hydrogen peroxide remaining in waste water, have simple to operate, hydrogen peroxide removal is thorough, efficient feature, will not cause secondary pollution.
