Daim ntawv thov ntawm cov geomembrane tiv thaiv kev seepage rau cov pas dej ntses thiab cov pas dej aquaculture

Cov ntaub ntawv kab lis kev cai ntawm cov ntses pas dej, cov ntaub ntawv aquaculture thiab cov chaw khaws dej tiv thaiv kev seepage geomembranes yog cov ntaub ntawv siv ntau hauv cov haujlwm txuag dej thiab aquaculture, thiab lawv muaj cov yam ntxwv sib txawv thiab cov xwm txheej siv.

Cov ntawv thov tshwj xeeb ntawm cov ntses pas dej yug me nyuam, aquaculture membranes thiab reservoir anti-seepage geomembranes hauv cov dej num txuag dej thiab aquaculture yog dab tsi?

Cov ntsiab lus twg yuav tsum tau them sai sai rau thaum lub sijhawm tso thiab vuam cov ntses pas dej yug me nyuam, cov aquaculture membranes thiab reservoir anti-seepage geomembranes?

1.Cov ntses pas dej kab lis kev cai membrane：

• Cov txheej txheem kab lis kev cai ntawm cov ntses hauv pas dej feem ntau yog siv rau kev tsim kho thiab kev saib xyuas cov pas dej ntses. Nws lub luag haujlwm tseem ceeb yog tiv thaiv kom tsis txhob muaj dej ntws hauv cov pas dej ntses thiab ua kom cov dej zoo ruaj khov.
• Cov yeeb yaj kiab no feem ntau yog ua los ntawm cov polyethylene siab (HDPE) Ua los ntawm lwm cov ntaub ntawv, nws muaj kev tiv thaiv kev laus zoo, tiv thaiv ultraviolet thiab tshuaj lom neeg ruaj khov.
• Cov ntaub thaiv kab lis kev cai ntawm cov ntses pas dej kuj tseem tuaj yeem hloov kho raws li qhov xav tau tshwj xeeb ntawm cov pas dej ntses, xws li ntau yam tuab, qhov loj me thiab xim, thiab lwm yam.

2.Cov ntaub ntawv ua liaj ua teb hauv dej：

• Cov ntaub thaiv dej aquaculture feem ntau yog siv rau hauv kev tsim cov pas dej aquaculture, cofferdams thiab lwm yam chaw. Nws lub hom phiaj tseem ceeb yog los muab ib puag ncig aquaculture zoo thiab tiv thaiv kev ua qias tuaj ntawm dej thiab dej xau.
• Daim nyias nyias no kuj yog ua los ntawm cov ntaub ntawv xws li polyethylene siab, uas muaj cov khoom tiv thaiv dej zoo, tiv taus corrosion thiab ruaj khov.
• Cov ntaub thaiv dej kuj tseem tuaj yeem hloov kho raws li qhov xav tau sib txawv ntawm cov tsiaj txhu thiab cov chaw ua liaj ua teb, xws li ntxiv cov neeg sawv cev tua kab mob, cov neeg sawv cev tiv thaiv algae, thiab lwm yam.

3.Geomembrane tiv thaiv kev seepage rau lub pas dej：

• Cov pas dej tiv thaiv geomembrane feem ntau yog siv rau hauv kev tsim cov dej num txuag dej xws li cov pas dej thiab cov pas dej. Nws lub luag haujlwm tseem ceeb yog tiv thaiv dej xau thiab txhim kho kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov dej num txuag dej.
• Cov yeeb yaj kiab no feem ntau yog ua los ntawm cov polyethylene siab, polyvinyl chloride (PVC) Thiab lwm yam ntaub ntawv, nrog kev ua tau zoo heev ntawm kev tiv thaiv dej, lub zog tensile thiab kev ua haujlwm ntev.
• Thaum lub sijhawm tsim kho, qhov zoo ntawm kev tso thiab kev vuam zoo ntawm cov geomembrane impermeable ntawm lub reservoir yuav tsum tau them sai sai kom ntseeg tau tias nws cov nyhuv impermeable.

Hauv ntej, cov ntaub thaiv kab lis kev cai ntawm cov ntses pas dej, cov ntaub thaiv aquaculture thiab cov chaw khaws dej tiv thaiv kev seepage geomembranes yog cov haujlwm tseem ceeb ntawm kev txuag dej thiab cov ntaub ntawv aquaculture nrog cov yam ntxwv sib txawv thiab cov xwm txheej siv. Thaum xaiv thiab siv cov ntaub ntawv no, yuav tsum tau txiav txim siab kom meej raws li qhov xav tau tshwj xeeb thiab cov xwm txheej tiag tiag.
