Description
Technical field
The invention belongs to sewage disposal process field, and in particular to a kind of integrated refractory wastewater and reclamation set
And sewage water treatment method.
Background technology
In recent years, China's water scarcity situation is aggravated, and water pollution situation but has no and is clearly better, and causes country to be gone into politics
Plan aspect has put into effect tightened up discharge standard, and actively promotes the recycling of waste water.
Industrial wastewater as waste water a main source, with complicated component, difficult degradation and poisonous and hazardous characteristic,
Actual treatment difficulty is very big.Due to existing, industrial wastewater operating service system is unsound, it is not in place to supervise, statistics limitation
The problems such as property, industrial wastewater actual discharge compliance rate will be far below statistics.Additionally, the weight of China's industry water resource
Multiple utilization rate is relatively low.
Compared with municipal wastewater, simple biochemical process treatment industrial wastewater is difficult to reach further strict discharge standard,
More limit the recycling of waste water.Therefore, increasing advanced treatment process on the basis of biochemical process, turning into
The major way of indegradable industrial effluent treatment up to standard and reuse is realized at present.Traditional advanced treatment of industrial waste water work
The skill method such as including absorption method, Coagulation Method, advanced oxidation processes.Wherein advanced oxidation processes are topmost advanced treating sides
Method.Advanced oxidation refers to carrying out oxidation reaction by producing the hydroxyl radical free radical (OH) with Strong oxdiative ability
Except or degraded water pollutant method.It is main to include sweet smell according to the mode and the difference of reaction condition that produce free radical
Oxidizing process, class Fenton oxidation method, Ozonation, photocatalytic oxidation, wet oxidation process of pausing etc..Industrial wastewater
Reuse mainly uses membrane separation process, according to the difference of reuse requirement, can be carried out using ultrafiltration, nanofiltration and reverse osmosis membrane
Reuse.
The principle of advanced oxidation processes is that the organic matter and reducing substances in water are aoxidized by hydroxyl radical free radical.With Fenton
As a example by oxidizing process, it is produced shown in the following reaction equation of cardinal principle of hydroxyl radical free radical.It is class Fenton oxidation method, smelly
The methods such as oxygen oxidizing process use different oxidant and catalyst to produce hydroxyl radical free radical.
Fe2++H2O2→Fe3++OH-+HO·
Fe3++H2O2+OH-→Fe2++H2O+HO·
Fe3++H2O2→Fe2++H++HO2
HO2+H2O2→H2O+O2↑+HO·
Membrane separation process refer to the mixture of different-grain diameter molecule on a molecular scale when by pellicle, realize selection
Property separate technology.Membranous wall is covered with aperture, can be divided into according to pore size：Microfiltration membranes, milipore filter, NF membrane,
Reverse osmosis membrane etc..In industrial effluent reusing, the main suspension gone in water removal using microfiltration membranes and milipore filter, big point
The materials such as sub- organic matter, part microorganism, realize the preliminary reuse of waste water.And further gone using nanofiltration and counter-infiltration
Organic matter and salt in water removal, to realize the high-quality reuse of waste water.
