Abstract
The invention discloses a method for killing limnoperna lacustris in a long-distance raw water conveying pipe through hydrogen peroxide, and relates to a method for killing the limnoperna lacustris in a raw water conveying pipe. The method comprises the steps that the hydrogen peroxide is thrown in the long-distance raw water conveying pipe at the temperature of 20 DEG C to 30 DEG C for 4 to 14 days, and the concentration of the hydrogen peroxide in the raw water is controlled to be 1 to 10 mg/L. According to the method for killing the limnoperna lacustris in the long-distance raw water conveying pipe through the hydrogen peroxide, the hydrogen peroxide not only has the effect of killing the limnoperna lacustris, but also has the good pre-oxidation effect as pre-oxidant. The hydrogen peroxide has the good removing effect on turbidity, algae, bacteria and coilform groups, and the difficulty of the follow-up water processing technology is not increased. The method for killing the limnoperna lacustris in the long-distance raw water conveying pipe through the hydrogen peroxide can effectively control the amount of the limnoperna lacustris in raw water and in the pipe, and by means of the method, operation is safe and convenient, and the feasibility is high.
Description
Technical field
The present invention relates to a kind of method of killing fresh water mussel in former water water pipe, relate in particular to a kind of method that hydrogen peroxide is killed fresh water mussel in the former water water pipe of long distance.
Background technology
The water quality deterioration that the fresh water mussel causes water pipe and biofouling problem are the new problems occurred in southern waterworks.The fresh water mussel is a kind of filter-feeding zoobenthos, they can be along the box culvert pipeline migrated downstream breeding of water supply project, intensive growth on tube wall, and enter the water supply plant of water supply works engineering, be attached to pump well, settling tank, stop up the structures such as grid, pipeline.Due to a large amount of fresh water mussel growth metabolisms in water of assembling, they are breathed and can consume the dissolved oxygen in water, and in metabolic process, excretion ammonia nitrogen and nutritive salt, cause water quality deterioration, and the increase of ammonia nitrogen can cause that the dosage of chlorine increases.Visible, the existence of fresh water mussel can cause water factory's operation difficulty, brings potential safety hazard, produces financial loss, therefore, for the control of fresh water mussel, is significant.
The existing method of killing fresh water mussel in pipeline mainly contains biological method, physical method and chemical process.Biological method is exactly to put black carp, carp etc. in a suitable place to breed at waterhead area can prey on the fish of fresh water mussel to prevent its amount reproduction.Physical method comprise adopt anti-adhesion, dried up desiccating method, high-temperature water spraying method, set up the pre-treatment facility, isolating oxygen method and artificial mechanism remove method.Chemical process mainly adopts the way that adds chemical agent, comprises that chlorine, lime, copper sulfate, sylvite, cupric oxide, ozone and various molluscicides etc. kill the fresh water mussel in water pipe.Although biological process is fundamentally controlled the growth and breeding of fresh water mussel, be the purpose of prevention, selected fish are limited by local economy, social condition, take effect slow, and cost is high and can not stop the fresh water mussel to enter water pipe fully.Though the Physical non-secondary pollution, most of measure of control complicated operation, be subject to effects limit more, and cost is higher, only in the feasible stage of theory.The chemical method time is short, instant effect, but some medicament can produce disinfection byproduct (DBP) in treating processes, and water quality safety is existed and threatens.Hydrogen peroxide is the liquid of colourless irritant smell.When it and organism meet, decompose immediately and generate oxygen.This Sauerstoffatom that not yet is combined into oxygen molecule, have very strong oxidation capacity. and when the hydrogen peroxide of doses and biological, can destroy biological cell, and then play killing action.After killing action, remaining material is without any murder by poisoning, without the water of any hormesis, can not form secondary pollution.Therefore, hydrogen peroxide is safer as oxygenant.
Summary of the invention
Poor in order to solve existing method complicated operation, the feasibility of killing fresh water mussel in former water water pipe, and adopt the method for killing of other sterilizing agents may produce disinfection byproduct (DBP), threaten the problem of drinking water safety, the invention provides a kind of hydrogen peroxide and kill the method for fresh water mussel in former water water pipe, this method is applicable to killing of fresh water mussel in the Long-distance Pipeline for Water Conveyance of south China area.
The objective of the invention is to realize by following steps:
In the situation that 20 ~ 30 ℃, add hydrogen peroxide in the former water water pipe of long distance, add continuously 4 ~ 14 days, controlling concentration of hydrogen peroxide in former water is 1 ~ 10mg/L, completes the method that hydrogen peroxide is killed fresh water mussel in former water water pipe.
In aforesaid method, under the condition of 20 ℃, when concentration of hydrogen peroxide is 10 mg/L in former water, add continuously 7.5 days, the mortality ratio of fresh water mussel is more than 90%.
In aforesaid method, under the condition of 25 ℃, when concentration of hydrogen peroxide is 5 mg/L in former water, add continuously 4 ~ 5 days, the mortality ratio of fresh water mussel is 70 ~ 80%.
In aforesaid method, under the condition of 25 ℃, when concentration of hydrogen peroxide is 10 mg/L in former water, add continuously 4 ~ 6 days, the mortality ratio of fresh water mussel is more than 70%, and at the 6th day of dispensing, fresh water mussel mortality ratio was 100%.
In aforesaid method, under the condition of 30 ℃, when concentration of hydrogen peroxide is 5mg/L in former water, add continuously 3 ~ 4.5 days, the mortality ratio of the 3rd day fresh water mussel is more than 70%, and the mortality ratio of the 4.5th day fresh water mussel is 100%.
Hydrogen peroxide of the present invention is killed in the method for fresh water mussel in former water water pipe, and controlling concentration of hydrogen peroxide in former water is 1 ~ 10mg/L, and it is 4 ~ 14 days that hydrogen peroxide adds the time continuously, and the mortality ratio of fresh water mussel is more than 70%.If fully the fresh water mussel is killed and needs the long period, from the economic angle analysis, and inadvisable, therefore controlling and adding continuously the time is 4 ~ 14 days.Also have, when the concentration of hydrogen peroxide added is too high, killing effect is poor on the contrary, and this is because the fresh water mussel can be taked the closed shell protection when oxidant concentration is higher, is unfavorable for the killing action of hydrogen peroxide to the fresh water mussel.
Hydrogen peroxide of the present invention is killed in the method for fresh water mussel in former water water pipe, and hydrogen peroxide not only has the effect of killing the fresh water mussel, as the preoxidation agent, preoxidation effect is preferably all arranged.Turbidity, algae, bacterium and coliform are all had to removal effect preferably, do not increase the difficulty of follow-up water technology.The present invention can effectively control the quantity of fresh water mussel in former water and pipeline, uses this technology, and easy-to-operate has high feasibility.
