Description
Technical field
The present invention relates to a kind of method for preventing and treating hydroenergy storage station reservoir fresh water mussel disaster.
Background technology
Fresh water mussel belongs to Mollusca, Bivalvia, Mytilidae, is distributed widely in the Lake Reservoir of south China river.Closely
Nian Lai, fresh water mussel is assembled in a large number at positions such as aqueduct, power station trash rack, tailwater tunnels；On the one hand cause water-supply-pipe
Road area of section reduces, and discharge capacity reduces, and hydroelectric station operation benefit is relatively low；On the other hand result even in line clogging, make
Become the security incidents such as hydraulic turbine shutdown.Additionally, fresh water mussel is in the structures surface adhesion of steel or concrete, can lead to construct
Thing surface protection film damages, and accelerates structures corrosion, shortens the life-span of structures.At present, in order to solve the above problems, generally adopt
Kill fresh water mussel with throwing in the physical methods such as chemical method or addition processing device such as oxidant.But, in water-storage
In power station, adjust reservoir day generate electricity, high water head and structures surface area is larger, using current chemically or physically
Implementation cost higher.Therefore, existing hydroenergy storage station has that on-road efficiency is relatively low, safety is undesirable, structures
The higher problem of life-span implementation cost that is shorter and killing fresh water mussel.
Content of the invention
It is an object of the invention to, a kind of method preventing hydroenergy storage station reservoir fresh water mussel disaster is provided.This
Bright can not only improve on-road efficiency, strengthen safety, extend the structures life-span, also have the advantages that implementation cost is low.
Technical scheme：A kind of method preventing and treating hydroenergy storage station reservoir fresh water mussel disaster, including once
Step：
A, reservoir watershed to hydroenergy storage station carry out Ecological Investigation, investigation whether there is fresh water mussel；
If b has fresh water mussel, carry out after early stage process Pumped Storage Power Station Construction again, if there is not fresh water mussel,
Then direct Pumped Storage Power Station Construction；
When c, Construction of Pumped Storage Power Station, brush fresh water mussel protective coating on gate, trash rack and conduit pipe surface；
After d, hydroenergy storage station are built up, carry out later stage process, the later stage is processed during process and the maintenance including when running
Process.
Early stage in a kind of aforesaid method preventing and treating hydroenergy storage station reservoir fresh water mussel disaster, in described step b
It is processed as, the water body in the region that there is fresh water mussel in reservoir and fresh water mussel easily is drained, make the riverbed in this region
It is exposed to the sun more than 3 months, building the filtering ponds filtering fresh water mussel at backwater of reservoir end 0.8km～1.2km simultaneously.
Operation in a kind of aforesaid method preventing and treating hydroenergy storage station reservoir fresh water mussel disaster, in described step d
When process be to throw in triangle Carnis Megalobramae and Mylopharyngodon piceus in reservoir, throw in density and be respectively 9～11 tails/100m3With 4～6 tails/
100m3, and check external ship and introduce whether Aquatic product carries fresh water mussel；Process during maintenance in step d is, to lock
Door, trash rack and conduit pipe carry out the drying of being exposed to the sun of more than 5 days, after maintenance, water volume flow rate in aqueduct are brought up to 2.5m/s
Above and continuous service more than 5 days.
Fresh water in a kind of aforesaid method preventing and treating hydroenergy storage station reservoir fresh water mussel disaster, in described step c
Mussel protective coating is SG305 liquid polyurethane rubber, and brushing density is 0.8kg/m2～1.2kg/m2.
Compared with prior art, present invention improves over the method preventing and treating hydroenergy storage station reservoir fresh water mussel disaster, lead to
Before crossing Construction of Pumped Storage Power Station, build neutralization and build up the process of rear three phases to prevent and treat fresh water mussel.The present invention is drawing water
Carry out Ecological Investigation before storage station's construction, carry out draining, be exposed to the sun to there is the reservoir watershed of fresh water mussel, by changing fresh water
The method of mussel living environment can kill 90% fresh water mussel；Then in gate, trash rack and conduit pipe table in construction
Fresh water mussel protective coating, the main attachment point of key protection fresh water mussel, the inspection that can be extended by least more than double are brushed in face
Repair the cycle；Finally throw in triangle Carnis Megalobramae and Mylopharyngodon piceus, the method by building biological chain after building up toward in reservoir, prevent fresh water shell
Dish is assembled in a large number, can remove in reservoir more than 95% fresh water mussel, then is prevented outer by the external ship of inspection and Aquatic product
The fresh water mussel invasion coming；In maintenance, prevent the existence of fresh water mussel and attachment by being exposed to the sun and increasing water volume flow rate；Thus
The fresh water mussel disaster of hydroenergy storage station reservoir can thoroughly be prevented and treated, improve the on-road efficiency of hydroenergy storage station, strengthen peace
Quan Xing, more than one times of prolongation structures life-span.Meanwhile, the present invention only need to be light in the brushing of gate, trash rack and conduit pipe surface
Water hull dish protective coating, compares traditional physical method and the implementation cost of chemical method reduces by 20%～40%.Therefore, this
Bright can not only improve on-road efficiency, strengthen safety, extend time between overhauls(TBO) and structures life-span, also there is implementation cost low
Advantage.
