Abstract
The invention discloses a methyl acrylate-containing wastewater treatment agent. The methyl acrylate-containing wastewater treatment agent comprises the following components in parts by weight: 8-12 parts of methyl acrylate, 5-9 parts of sodium silicate, 4-7 parts of polyvinyl alcohol, 9-11 parts of hydroxymethyl cellulose, 3-4 parts of ferrous sulfate and 130-145 part of de-ionized water. By adopting the prepared methyl acrylate-containing wastewater treatment agent, the CODcr (Chemical Oxygen Demand) value and the total phosphorus value in the wastewater can be obviously reduced.
Description
Technical field
The present invention relates to a kind of waste water conditioner, particularly relate to a kind of waste water conditioner that contains methyl acrylate.
Background technology
We can produce very many family domestic waste waters in life.In these family domestic waste waters, a large amount of pollutents is arranged.Wherein nitrogenous compound is as nitrite nitrogen, nitrate nitrogen, inorganic salt nitrogen, dissolved nitrogen etc., caused in family domestic waste water total nitrogen higher, and in domestic waste water, total phosphorus content is also very high in addition.These are all the main sources of the pollutent in domestic waste water.Adopting certain method to reduce total nitrogen and the total phosphorus content in family domestic waste water, has been an extremely urgent problem that must solve.
Summary of the invention
The technical problem solved: CODcr value and the too high problem of total phosphorus value in trade effluent.
Technical scheme: the invention discloses a kind of waste water conditioner that contains methyl acrylate, the waste water conditioner that contains methyl acrylate is comprised of according to weight ratio following composition: methyl acrylate is that 8～12 parts, water glass are that 5～9 parts, polyvinyl alcohol are that 4～7 parts, Walocel MT 20.000PV are that 9～11 parts, ferrous sulfate are that 3～4 parts, deionized water are 130～145 parts.By add organic floculant methyl acrylate and polyvinyl alcohol in waste water conditioner, organic floculant is combined with inorganic flocculating agent, performance flocculation and clarification, reduce the total amount of pollutant in trade effluent, the water quality of lifting waste water, reach the respective standard of national blowdown, reduces environmental pollution.
The preparation process of the waste water conditioner that contains methyl acrylate is as follows: each moiety methyl acrylate of getting treatment agent is that 8～12kg, water glass are that 5～9kg, polyvinyl alcohol are that 4～7kg, Walocel MT 20.000PV are that 9～11kg, ferrous sulfate are that 3～4kg, deionized water are 130～145kg.Mentioned component is mixed, after mixing, be prepared into waste water conditioner.
Beneficial effect: the waste water conditioner that contains methyl acrylate that the present invention prepares can significantly reduce CODcr value and the total phosphorus value in waste water, and the CODcr value is down to 13～16mg/L from 1730mg/L, and the total phosphorus value is reduced to 0.7～1.3mg/L from 89mg/L.
Embodiment
Embodiment 1
Methyl acrylate is that 8kg, water glass are that 9kg, polyvinyl alcohol are that 4kg, Walocel MT 20.000PV are that 11kg, ferrous sulfate are that 3kg, deionized water are 130kg.Mentioned component is mixed, after mixing, be prepared into waste water conditioner.
Embodiment 2
The preparation method is with embodiment 1, and concrete component content is as follows: methyl acrylate is that 10kg, water glass are that 5kg, polyvinyl alcohol are that 7kg, Walocel MT 20.000PV are that 10kg, ferrous sulfate are that 4kg, deionized water are 140kg.
Embodiment 3
The preparation method is with embodiment 1, and concrete component content is as follows: methyl acrylate is that 12kg, water glass are that 7kg, polyvinyl alcohol are that 5kg, Walocel MT 20.000PV are that 9kg, ferrous sulfate are that 3kg, deionized water are 145kg.
The Industrial Wastewater Treatment test
Get trade effluent 3kg, be divided into 3 parts, every part is 1kg.In 3 parts of waste water, the CODcr value is 1730mg/L, and the total phosphorus value is 89mg/L.The waste water conditioner addition of embodiment 1, embodiment 2, embodiment 3 is the 1.5wt% of waste water weight.Join respectively in waste water, standing after stirring 20min, time of repose is 1.5h, gets supernatant liquor after 1.5h, measures CODcr value and total phosphorus value:
| ? | Before processing | After embodiment 1 processes | After embodiment 2 processes | After embodiment 3 processes |
| CODcr value (mg/L) | 1730 | 15 | 13 | 16 |
| Total phosphorus value (mg/L) | 89 | 0.8 | 0.7 | 1.3 |
From table, result can be found out, the waste water of processing through treatment agent of the present invention, and the CODcr value is down to 13～16mg/L from 1730mg/L, and the total phosphorus value is reduced to 0.7～1.3mg/L from 89mg/L.
Claims (5)
