Description
Technical field
The present invention relates to sewage disposal technology, be specifically related to a kind of paper making sewage processing method。
Background technology
Paper industry energy consumption, material consumption height, environmental pollution is also very serious, and wherein SS, COD concentration in waste water is higher, and environment and human health are brought significant damage。Environment is the place that the mankind depend on for existence, and health birth and old age, sickness and death are played vital effect。The pollution of environment has water pollution, atmospheric pollution, soil pollution, and wherein water pollution is most important on the impact of environment。Water resource is the indispensable important natural resources of developing national economy。Many places in the world, the demand of water is alreadyd more than water resource can the degree of load, have many areas to be also on the verge of the imbalance of water resource utilization, so we to treasure water resource simultaneously。Along with the destruction of the mankind, " crystal ball " of that sky blue originally is no longer bright and limpid, no longer azure, is about to withered。For a long time, the environment event caused due to commercial production sewage directly outer row is of common occurrence, and it brings pole bad influence to human being's production, life。Water is the material base that tellurian is depended on for existence, and water resource is the most important condition maintaining ball ecological environment sustainable development, and therefore, water conservation is the bounden duty that the mankind are great, the most sacred。Treatment of Industrial Water is an important ring, and industrial wastewater only has correct water treatment technology ability qualified discharge, could reduce water and process pollution。
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of paper making sewage processing method。
The technical scheme is that a kind of paper making sewage processing method, comprise the following steps: former water oblique net successively, the first mixed reaction pond, the first heavy pond, oxidation ditch, complete pretreatment；Oxidation ditch water outlet adds bodied ferric sulfate at the first catalyst oxidation reactor, enters the second mixed reaction pond, and add PAMA in the second mixed reaction pond after reaction, discharges, complete advanced treating after the 3rd heavy pond flocculation sediment。
The technical scheme is that
The addition of described bodied ferric sulfate is that every cubic metre of sewage adds 2-3kg。
The concentration of described PAMA is 8ppm。
The described catalytic oxidation time is no less than 20 minutes。
Described 3rd heavy pond discharge after water react with hydrogen peroxide, ferrous sulfate then through the second catalyst oxidation reactor after enter the 4th mixed reaction pond and PAMA (PAM) hybrid reaction, with after precipitate discharge through the 4th heavy pond。
The addition of described bodied ferric sulfate is that every cubic metre of sewage adds 4kg。
The concentration of described PAMA is 8PPM。
The concentration of described hydrogen peroxide is 27.5, and addition is every cubic metre of 3kg。
The described water discharged through the 4th heavy pond needed to add alkali before discharging and regulates pH value to 6-9。
Present invention process is simple, and reliable and stable, waste water COD after treatment can be down to 45mg/l。
Accompanying drawing explanation
Fig. 1 is present invention process flow chart。
Fig. 2 is preferred embodiment of the present invention process chart。
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated。
As it is shown in figure 1, one paper making sewage processing method of the present invention, comprise the following steps: former water oblique net successively, the first mixed reaction pond, the first heavy pond, oxidation ditch, complete pretreatment；Oxidation ditch water outlet adds bodied ferric sulfate at the first catalyst oxidation reactor, enters the second mixed reaction pond, and add PAMA in the second mixed reaction pond after reaction, discharges, complete advanced treating after the 3rd heavy pond flocculation sediment。The addition of described bodied ferric sulfate is that every cubic metre of sewage adds 2-3kg。The concentration of described PAMA is 8ppm。The described catalytic oxidation time is no less than 20 minutes。
Oxidation ditch water outlet adds 2-3kg/m at the first catalyst oxidation reactor3Bodied ferric sulfate, reaction certain time is about 20min, adds the PAMA of 8PPM, and through the 3rd heavy pond flocculation sediment, waste discharge COD can reach below 75mg/l。
As in figure 2 it is shown, one paper making sewage processing method of the present invention, comprise the following steps: former water oblique net successively, the first mixed reaction pond, the first heavy pond, oxidation ditch, complete pretreatment；Oxidation ditch water outlet adds bodied ferric sulfate at the first catalyst oxidation reactor, enters the second mixed reaction pond, and add PAMA in the second mixed reaction pond after reaction, discharges, complete advanced treating after the 3rd heavy pond flocculation sediment。The addition of described bodied ferric sulfate is that every cubic metre of sewage adds 2-3kg。The concentration of described PAMA is 8ppm。The described catalytic oxidation time is no less than 20 minutes。Described 3rd heavy pond discharge after water react with hydrogen peroxide, ferrous sulfate then through the second catalyst oxidation reactor after enter the 4th mixed reaction pond and PAMA (PAM) hybrid reaction, with after precipitate discharge through the 4th heavy pond。Wherein, the addition of described bodied ferric sulfate is that every cubic metre of sewage adds 4kg。The concentration of described PAMA is 8PPM。The concentration of described hydrogen peroxide is 27.5, and addition is every cubic metre of 3kg。The described water discharged through the 4th heavy pond needed to add alkali before discharging and regulates pH value to 6-9。
For ensureing discharged wastewater met the national standard, test of many times in laboratory, uses merely bodied ferric sulfate, all cannot ensure that water processes requirement, it is used alone Fenton process (namely with ferrous sulfate and hydrogen peroxide) simultaneously and also cannot meet water process requirement, and cost is high especially。Sewage advanced treatment was all single use a certain method in the past, combined without attempting two kinds of methods。Through making repeated attempts and testing in test chamber, have found a kind of effective means at last, namely waste water is after Polyferric Sulfate has processed, then carries out two stage treatment and Fenton process (namely with ferrous sulfate and hydrogen peroxide), waste water is after two stages for the treatment of, and waste water can qualified discharge COD≤50mg/l。
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described。Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention。Claimed scope is defined by appending claims and equivalent thereof。
