Description
Technical field
The invention belongs to sewage-treating agent technical field, relate in particular to a kind for the treatment of agent that is applied to papermaking wastewater.
Background technology
Industrial pollution caused by paper manufacturing is serious, and quantity of wastewater effluent is large, and every production 1t slurry will produce 80m
3sewage.In the papermaking wastewater now having detected, organic pollutant just has kind more than 300, and paper maker had become global the sixth-largest contamination industry already.Have and report in Canadian river that 50% water pollutant is discharged by pulp and paper industry.The pollution of paper industry sewage can't neglect paper industry sewage discharge and understand the havoc eubiosis in river.
In existing paper mill sewage treatment method, have and adopt the poly aluminium chloride that adds 0.1% in settling tank, make sewage produce flocculation, precipitation.Because poly aluminium chloride price is higher, cost of sewage disposal is higher, and treatment effect is undesirable, does not still reach emission request.Employing polymeric ferric salt in addition, alkaline material, polyacrylamide etc. are added in papermaking wastewater according to a certain percentage for main raw material, by cracking viscosity and the molecular structure of black liquor, make that the compositions such as xylogen in black liquid, hemicellulose, silicon-dioxide are degraded, precipitating, grain slag separates.This method can make the COD of upper water remove 80%, but sediment can not fully utilize.
CN200510038282.5 has announced a kind for the treatment of agent for papermaking wastewater, mainly comprise sweet potato starch, Si oxide and flora composition, this treatment agent has improved some performance index of sewage to a certain extent, but owing to having added flora, so make technique wayward, be difficult to reach the object of automation technolo.
CN200910213220.1 has announced a kind of papermaking wastewater discoloring agent formula, mainly comprises lignin, ammonium pyrosulfate, trimethylammonium cyclopropane ammonium chloride, sulfuric acid.This treatment agent to a certain extent, reached the object of decolouring, but effect is single.
CN200910213221.6 has announced a kind for the treatment of agent for papermaking wastewater formula, mainly comprises W-Gum, polyacrylamide, 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride, sodium-acetate.In this treatment agent, having added W-Gum, be generally for biochemical treatment below provides carbon source, but this technique is not mentioned follow-up biochemical treatment.
At present, researched and developed a large amount for the treatment of agent for papermaking wastewaters, still, these treatment agents are all on traditional treatment agent basis, to have carried out some to improve, not tangible innovation, and also most for the treatment of agent all has function singleness, is difficult to the shortcomings such as recycling.Develop the new sewage-treating agent of a kind of innovation multi-functional, that can reuse and seem particularly important.
Summary of the invention
A kind of novel sewage treatment agent that the object of the invention is the shortcoming of the function singleness in order to solve existing treating agent for papermaking wastewater, not reproducible utilization and invent.Through this treatment agent, process sewage later and reached GB18918-2002 standard, can be used for the aspects such as field irrigation, domestic water, and the formula material of this treatment agent is cheap and easy to get, greatly reduces the cost of sewage disposal.
Technical scheme of the present invention: treating agent for papermaking wastewater of the present invention, is comprised of following component by weight:
Flocculation agent 40-55 part, sequestrant 15-25 part, sorbent material 10-15 part, PH conditioning agent 5-35 part.
Flocculation agent is mainly: poly-propionic acid amide, dithiocar-bamate (DTC), Tai-Ace S 150, ferrous sulfate.
Sequestrant is mainly: hexametaphosphate, tri-polyphosphate, citric acid, EDTA, DTPA.
Sorbent material is mainly: macroporous resin.
PH conditioning agent is mainly: sodium-acetate, sulfuric acid.
Beneficial effect of the present invention is:
(1), in this sewage-treating agent, owing to having added flocculation agent, COD, the BOD of sewage and SS amount are obviously reduced;
(2), in this sewage-treating agent, due to adding of sequestrant and macroporous resin, the metal ion content of sewage is obviously reduced; And because macroporous resin can reuse by wash-out, this has just made very large contribution for economizing in raw materials;
(3), in this sewage-treating agent, owing to having added PH conditioning agent, make the PH of sewage approach neutral;
(4) this sewage-treating agent has overcome the existing function singleness of existing treatment agent and has been difficult to the shortcoming of recycling;
In a word, this sewage-treating agent can make the physical and chemical index of papermaking wastewater reach GB18918-2002 standard, thereby reaches emission standard.
embodiment:
In order to understand better technical scheme of the present invention, below by specific embodiment, be further described in detail.
Take respectively treating agent for papermaking wastewater A, B, C, D, E, F, G adds in detention tank, and itself and commercially available treating agent for papermaking wastewater are compared.Using COD, BOD, SS, metal ion content, PH, as judgement criteria, tested respectively the treatment effect of sewage-treating agent of the present invention.
embodiment 1:
Take 40 parts of poly-propionic acid amides; 15 parts of hexametaphosphates; 10 parts of macroporous resins; 35 parts of sodium-acetates are mixed to get treatment agent A.
embodiment 2:
Take DTC40 part; 15 parts of tri-polyphosphates; 10 parts of macroporous resins; 35 parts, sulfuric acid is mixed to get treatment agent B.
embodiment 3:
Take 45 parts, Tai-Ace S 150; 20 parts of citric acids; 15 parts of macroporous resins; 20 parts of sodium-acetates are mixed to get treatment agent C.
embodiment 4:
Take 50 parts, ferrous sulfate; EDTA25 part; 15 parts of macroporous resins; 10 parts, sulfuric acid is mixed to get treatment agent D.
embodiment 5:
Take 55 parts of poly-propionic acid amides; DTPA15 part; 15 parts of macroporous resins; 15 parts of sodium-acetates are mixed to get treatment agent E.
embodiment 6:
Take 50 parts, ferrous sulfate; EDTA25 part; 13 parts of macroporous resins; 12 parts of sodium-acetates are mixed to get treatment agent F.
embodiment 7:
Take 50 parts, ferrous sulfate; DTPA15 part; 13 parts of macroporous resins; 22 parts, sulfuric acid is mixed to get treatment agent G.
test implementation example:
Taking respectively treatment agent A, B, C, D, E, F, G and commercially available treating agent for papermaking wastewater H1Kg joins in the papermaking wastewater of 20Kg, temperature control is at 25 ℃, constantly stir 1h, the effect of having tested respectively sewage-treating agent of the present invention using COD, BOD, SS, metal ion content and PH as judgement criteria, test result is as table 1.
Table 1
As can be seen here, sewage-treating agent of the present invention can effectively reduce COD, BOD, SS and the metal ion content of sewage, can make the PH of sewage reach approaching neutral, reaches emission standard.And its effect is to be better than commercially available treating agent for papermaking wastewater.
