Abstract
The invention discloses a method for killing fresh water moule in a raw water transportation pipeline by utilizing potassium permanganate and relates to a method for killing the fresh water moule in the raw water transportation pipeline, solving the problems that the existing method for killing the fresh water moule in the raw water transportation pipeline is complicated in operation and is poor in feasibility, disinfection byproducts are generated by using a killing method in which a chloride-containing disinfector is used so as to threaten the safety of drinking water. The method comprises the step of continuously adding the potassium permanganate in the raw water transportation pipeline for 5-12 days, wherein the concentration of the potassium permanganate in each L of raw water is controlled to 1.2-1.5 mg, so that the fresh water moule in the raw water transportation pipeline is killed. The potassium permanganate can oxidize and kill the fresh water moule, the mortality of the fresh water moule is above 70%; and simultaneously, the potassium permanganate can remove fume in water and can exert a nuclear coagulation effect of manganese dioxide, thus the purposes of flocculation and precipitation are achieved in advance, and the difficulty of subsequently water treatment process is not increased. According to the invention, operation is simple, safe and stable, and no disinfection byproducts are generated, thus the method has an extremely high practicability.
Description
Technical field
The present invention relates to a kind of method of killing fresh water mussel in the former water water pipe.
Background technology
The fresh water mussel is the water treatment new problem that present China south runs into, and not only can influence the ecologic structure of local water body, the destruction of causing the ecosystem, and particularly in former water Long-distance Pipeline for Water Conveyance, the fresh water mussel can be bred in a large number, harm waterworks safety.The characteristic and have flourishing byssus because it is gregariousness can form the colony of stacked in multi-layers in pipeline, increase the water delivery resistance of pipeline, deterioration water quality.Simultaneously, the fresh water mussel that death comes off at the pipeline turning and the thief hatch place cause alluvial, influence the normal operation of pipeline discharge capacity and monitor and control facility.Therefore, the control for the fresh water mussel is significant.
The existing method of killing fresh water mussel in the pipeline mainly contains physical method and chemical process.Physical method comprises employing anti-adhesion coating, high-temperature water spraying method, sets up the pre-treatment facility, seals anoxic method and artificial mechanism removing method.But its complicated operation, effects limit is more, and feasibility is poor.Adopt anti-adhesion coating way to be only applicable to newly-built pipeline, it is big to set up pre-treatment facilities engineering amount.Chemical process mainly adopts the way that adds chemical agent, comprise chlorine, lime, copper sulfate, sylvite, cupric oxide, ozone and various molluscicides etc., but consider safety of drinking water, in the processing that a lot of medicaments can't be used for drinking water, though wherein chlorine-containing disinfectant can be used in water factory, but the generation of disinfection byproduct (DBP) is threatening safety of drinking water again, and dosage also is restricted.
Summary of the invention
It is poor to the objective of the invention is in order to solve existing method complicated operation, the feasibility of killing fresh water mussel in the former water water pipe, and adopt the method for killing of chlorine-containing disinfectant to produce disinfection byproduct (DBP), threaten the problem of drinking water safety, the invention provides the method that a kind of potassium permanganate is killed fresh water mussel in the former water water pipe.
Potassium permanganate of the present invention is killed the method for fresh water mussel in the former water water pipe, realize by following steps: in former water water pipe, add potassium permanganate, added continuously 5～12 days, control that potassium permanganate concentration reaches 1.2～1.8mg in every liter of former water, finish the method that potassium permanganate is killed fresh water mussel in the former water water pipe.
Potassium permanganate of the present invention is killed in the method for fresh water mussel in the former water water pipe, when former water water temperature is 21～25 ℃, adds potassium permanganate in former water water pipe, adds continuously 5～8 days.The mortality ratio of fresh water mussel reaches more than 80%.
Potassium permanganate of the present invention is killed in the method for fresh water mussel in the former water water pipe, when former water water temperature is 15～20 ℃, adds potassium permanganate in former water water pipe, adds continuously 8～12 days.The mortality ratio of fresh water mussel reaches more than 70%.
Potassium permanganate of the present invention is killed in the method for fresh water mussel in the former water water pipe, control potassium permanganate continuously the time of adding be 5～12 days, potassium permanganate concentration reaches 1.2～1.8mg in every liter of former water, the mortality ratio of fresh water mussel reaches more than 70%.Need the long period if fully the fresh water mussel is killed, from the economic angle analysis, and inadvisable, the time of adding is 5～12 days continuously therefore to control potassium permanganate.Also have, when the potassium permanganate concentration that adds reached 1.5mg/L, killing effect was best, and the mortality ratio of fresh water mussel reaches more than 80%; Rate of death has decline to density loss slightly to 1.2mg/L or when being increased to 1.8mg/L.If the concentration that increases potassium permanganate again is to more than the 1.8mg/L, the fresh water mussel just carries out closed shell self-protection, and the closed shell time can reach for 1 week when water temperature was 16 ℃, and during this period, any medicament is all inoperative.Only remain fresh water mussel closed shell with the idiotrophic material consumption totally, just dead successively, increased cost on the contrary, reduced the efficient of killing.Therefore, the invention provides the water treatment method of a kind of economy, safety.
Compare with the method for killing of chlorine-containing disinfectant, potassium permanganate has simple to operate, stable characteristics, and does not have the disinfection byproduct (DBP) generation.Simultaneously, potassium permanganate can be removed and smell flavor in the water, reaches the effect of deironing, demanganization, in addition, can also bring into play the nuclear effect of coagulating of Manganse Dioxide, reaches flocculation and sedimentary purpose in advance, and does not increase the difficulty of follow-up water technology.The most important thing is in former water water pipe, to add potassium permanganate, oxygenizement is carried out to greatest extent, kill the fresh water mussel, and then it is removed from pipeline, solve the problem of fresh water mussel harm water pipe water delivery effect.
The present invention can effectively control the quantity of fresh water mussel in former water and the pipeline, uses this technology, and easy-to-operate has high feasibility.
