Abstract
The invention discloses a silicon dioxide-containing wastewater treatment agent. The wastewater treatment agent consists of the following components in parts by weight: 4-6 parts of silicon dioxide, 6-7 parts of hydroxypropyl starch, 3-6 parts of magnesium sulfate, 7-9 parts of ethyl cellulose, 7-11 parts of calcium silicate and 150-180 parts of de-ionized water. By adopting the prepared silicon dioxide-containing wastewater treatment agent, the CODcr (Chemical Oxygen Demand) value and the total nitrogen value in the wastewater are obviously reduced, and the total amount of pollutants in the wastewater is 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 silicon-dioxide.
Background technology
At present, the pollution problem that economic fast development brings should not be underestimated, and we need to pay attention to environmental protection work.The very important control that link is exactly water quality in environmental protection work.Reducing the Pollutants in Wastewater total amount, is the significant problem faced at present.The total amount of pollutant in waste water directly affects people's health.The chemical oxygen demand value and the total nitrogen value that reduce in waste water are necessary very much.Have at present some to adopt chemistry or microbiology to reduce the method for chemical oxygen demand value and total nitrogen value, still effect is still poor generally, remains to be proceeded further deep research.
Summary of the invention
The technical problem solved: CODcr value and the too high problem of total nitrogen value in trade effluent.
Technical scheme: the invention discloses a kind of waste water conditioner that contains silicon-dioxide, waste water conditioner is comprised of according to weight ratio following composition: silicon-dioxide is that 4～6 parts, hydroxypropylated starch are that 6～7 parts, sal epsom are that 3～6 parts, ethyl cellulose are that 7～9 parts, Calucium Silicate powder are that 7～11 parts, deionized water are 150～180 parts.Wherein, silicon-dioxide is preferably 4 parts; Hydroxypropylated starch is preferably 6 parts; Sal epsom is preferably 6 parts; Ethyl cellulose is preferably 7 parts; Calucium Silicate powder is preferably 11 parts.
The preparation process of the waste water conditioner that contains silicon-dioxide is as follows: each moiety of at first getting treatment agent: silicon-dioxide is that 4～6kg, hydroxypropylated starch are that 6～7kg, sal epsom are that 3～6kg, ethyl cellulose are that 7～9kg, Calucium Silicate powder are that 7～11kg, deionized water are 150～180kg.Temperature of reactor is set as to 70 ℃, then, by hydroxypropylated starch and ethyl cellulose deionized water dissolving, after stirring, is reduced to room temperature, add silicon-dioxide, sal epsom, Calucium Silicate powder under room temperature.After all the components mixes, be prepared into the waste water conditioner that contains silicon-dioxide.
Beneficial effect: the waste water conditioner that contains silicon-dioxide that the present invention prepares has reduced CODcr value and the total nitrogen value in waste water significantly, and the CODcr value is down to 15～18mg/L from 1600mg/L, and the total nitrogen value is reduced to 0.4～0.6mg/L from 70mg/L.
Embodiment
Embodiment 1
Get each moiety for the treatment of agent: silicon-dioxide is that 6kg, hydroxypropylated starch are that 6kg, sal epsom are that 3kg, ethyl cellulose are that 7kg, Calucium Silicate powder are that 11kg, deionized water are 180kg.Temperature of reactor is set as to 70 ℃, then, by hydroxypropylated starch and ethyl cellulose deionized water dissolving, after stirring, is reduced to room temperature, add silicon-dioxide, sal epsom, Calucium Silicate powder under room temperature.After all the components mixes, be prepared into the waste water conditioner that contains silicon-dioxide.
Embodiment 2
Get each moiety for the treatment of agent: silicon-dioxide is that 4kg, hydroxypropylated starch are that 7kg, sal epsom are that 4kg, ethyl cellulose are that 8kg, Calucium Silicate powder are that 9kg, deionized water are 160kg.Temperature of reactor is set as to 70 ℃, then, by hydroxypropylated starch and ethyl cellulose deionized water dissolving, after stirring, is reduced to room temperature, add silicon-dioxide, sal epsom, Calucium Silicate powder under room temperature.After all the components mixes, be prepared into the waste water conditioner that contains silicon-dioxide.
Embodiment 3
Get each moiety for the treatment of agent: silicon-dioxide is that 5kg, hydroxypropylated starch are that 6kg, sal epsom are that 6kg, ethyl cellulose are that 9kg, Calucium Silicate powder are that 7kg, deionized water are 150kg.Temperature of reactor is set as to 70 ℃, then, by hydroxypropylated starch and ethyl cellulose deionized water dissolving, after stirring, is reduced to room temperature, add silicon-dioxide, sal epsom, Calucium Silicate powder under room temperature.After all the components mixes, be prepared into the waste water conditioner that contains silicon-dioxide.
The waste water conditioner Processing Test that contains silicon-dioxide
Get waste water a certain amount of, be divided into 3 parts.In 3 parts of waste water, the CODcr value is 1600mg/L, and the total nitrogen value is 70mg/L.The waste water conditioner addition of embodiment 1, embodiment 2, embodiment 3 is 3% of waste water weight.Join respectively in waste water, carry out after gentle agitation standingly, time of repose is 4h, measures CODcr value and total nitrogen value in supernatant liquor after 4h.Result is as follows:
| ? | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| CODcr value (mg/L) | 18 | 16 | 15 |
| Total nitrogen value (mg/L) | 0.5 | 0.6 | 0.4 |
As can be seen from the table, the waste water of processing with the waste water conditioner that contains silicon-dioxide of the present invention, its CODcr value and total nitrogen value have all obtained obvious reduction, can be applied in wastewater treatment.
