Abstract
The invention discloses a method for preventing and treating a reservoir fresh water mussel disaster of a pumped storage power station. The method includes the steps that firstly, ecological investigation is performed, early-stage treatment is performed on a drainage basin with fresh water mussels, the pumped storage power station is established after treatment, the surfaces of a gate, a trash rack and a diversion pipeline are coated with fresh water mussel protective paint, later-stage treatment is performed finally, triangular breams and black carp are put into the drainage basin, and the fresh water mussel disaster is prevented and treated by exposing the mussels under the sun and increasing the water flow speed. Through treatment performed before, during and after the establishment of the pumped storage power station, the fresh water mussels are prevented and treated, methods for changing the living environment of the fresh water mussels and establishing a biologic chain are mainly adopted for preventing and treating the fresh water mussels, and the surfaces of the gate, the trash rack and the diversion pipeline are coated with the protective paint, so that key protection is achieved. The method has the beneficial effects that operation benefits can be improved, safety is enhanced, an overhaul period and the service life of a building are prolonged, and implementing cost is low.
Description
Technical field
The present invention relates to a kind of method for preventing and treating pumped storage power plant 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.In recent years, fresh water mussel is assembled in a large number at positions such as aqueduct, power station trashrack, tailwater tunnels; Cause aqueduct section area to reduce on the one hand, discharge capacity reduces, and hydroelectric station operation benefit is lower; Even can cause line clogging on the other hand, cause the security incidents such as hydraulic turbine shutdown.In addition, fresh water mussel, in steel or concrete structure surface adhesion, can cause structure surface protection film to damage, and accelerates structure corrosion, shortens the life-span of structure.At present, in order to solve the problem, the physical methods such as chemical method or addition processing device such as throwing in oxidant is usually adopted to kill fresh water mussel.But, in pumped storage power plant, regulate generating, high water head and structure superficial area comparatively large reservoir day, adopt the implementation cost of current chemical method or physical method higher.Therefore, existing pumped storage power plant also exists that on-road efficiency is lower, safety is undesirable, the structure life-span is shorter and kills the higher problem of the implementation cost of fresh water mussel.
Summary of the invention
The object of the invention is to, a kind of method preventing pumped storage power plant reservoir fresh water mussel disaster is provided.The present invention can not only improve on-road efficiency, strengthens safety, extends the structure life-span, also has the advantage that implementation cost is low.
Technical scheme of the present invention: a kind of method of preventing and treating pumped storage power plant reservoir fresh water mussel disaster, comprises step:
A, carry out Ecological Investigation to pumped storage power plant is reservoir watershed, whether investigation exists fresh water mussel;
If b exists fresh water mussel, then carry out Pumped Storage Power Station Construction again after process in early stage, 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, trashrack and conduit pipe surface;
After d, pumped storage power plant are built up, carry out post-processed, process when process when post-processed comprises operation and maintenance.
Aforesaidly a kind ofly prevent and treat in the method for pumped storage power plant reservoir fresh water mussel disaster, early stage in described step b is treated to, to fresh water mussel be there is in reservoir and easily occur that the water body in region of fresh water mussel drains, the riverbed in this region is exposed to the sun more than 3 months, is building the filtering ponds filtering fresh water mussel apart from backwater of reservoir end 0.8km ~ 1.2km place simultaneously.
Aforesaidly a kind ofly prevent and treat in the method for pumped storage power plant reservoir fresh water mussel disaster, process during operation in described steps d is in reservoir, throw in triangle gurnet and black carp, throws in density and is respectively 9 ~ 11 tails/100m
3with 4 ~ 6 tails/100m
3, and check external boats and ships and whether introduce aquatic products with fresh water mussel; Process during maintenance in steps d is gate, trashrack and conduit pipe are carried out to the drying of being exposed to the sun of more than 5 days, after maintenance, water volume flow rate in aqueduct is brought up to more than 2.5m/s and continuous service more than 5 days.
Aforesaidly a kind ofly prevent and treat in the method for pumped storage power plant reservoir fresh water mussel disaster, the fresh water mussel protective coating in described step c is SG305 liquid polyurethane rubber, and brushing density is 0.8kg/m
2~ 1.2kg/m
2.
Compared with prior art, present invention improves over the method for preventing and treating pumped storage power plant reservoir fresh water mussel disaster, by before Construction of Pumped Storage Power Station, build the process that neutralization builds up rear three phases and prevent and treat fresh water mussel.The present invention carries out Ecological Investigation before Construction of Pumped Storage Power Station, reservoir watershedly carries out draining, is exposed to the sun, can kill 90% fresh water mussel by the method changing fresh water mussel living environment to what there is fresh water mussel; Then in construction, fresh water mussel protective coating is brushed on gate, trashrack and conduit pipe surface, the main attachment point of key protection fresh water mussel, the time between overhauls(TBO) that can be extended by least more than double; Finally after building up, in reservoir, throw in triangle gurnet and black carp, by building the method for biological chain, prevent fresh water mussel from assembling in a large number, the fresh water mussel of in reservoir more than 95% can be removed, then by checking that external boats and ships and aquatic products prevent external fresh water mussel invasion; When overhauling, prevent fresh water mussel from surviving and attachment by being exposed to the sun and increasing water volume flow rate; Thus thoroughly can prevent and treat the fresh water mussel disaster of pumped storage power plant reservoir, improve the on-road efficiency of pumped storage power plant, strengthen safety, extend the structure life-span more than one times.Meanwhile, the present invention only need brush fresh water mussel protective coating on gate, trashrack and conduit pipe surface, and the implementation cost comparing traditional physical method and chemical method reduces by 20% ~ 40%.Therefore, the present invention can not only improve on-road efficiency, strengthens safety, extends time between overhauls(TBO) and structure life-span, also has the advantage that implementation cost is low.
