The higher the air purifier filter level, the better? With the arrival of the 'Golden nine silver ten' in the traditional sales season of home appliance industry,Enterprises have released new products in advance to seize the market opportunity,The market performance of air purifiers is particularly prominent,Recently, Samsung, Midea, sharp, wanjiale and other companies have released related new products.Just when the company has just announced that the new product is ready to be sold,However, domestic monitoring agencies have issued reports on the poor effect of removing formaldehyde from air purifiers,At that time, the air purifier purification effect has become the focus of attention in the industry.For many air purifiers on the market, the nominal 'formaldehyde removal rate 99%' and 'PM2.5 removal rate of 99% 'and other phenomena,Recently, the national indoor interior environment and environmental protection product quality supervision and inspection center (hereinafter referred to a
Help: how to lay the filter tank above the fish tank? Placement order: the top is ordinary filter cotton,Water passes through it first,Filter out large impurities.The second layer is biochemical cotton,Porcelain ring (the more the better ).Fish farming started,That is, when the water is ready to release the fish,Don't put too much fish,The * chemical bacteria * of the fish tank did not form,The water quality is unstable.Too much fish at a time,It is easy to change the fish tank into a 'milk tank ',It is best to introduce some * strains,Fish market is generally available,It's best to buy solid,Cheap liquid,More fake,And then all you have to do is keep filtering.Remember: filtering can't stop,Bacteria like high oxygen,A dark environment.Once you stop filtering,The bacteria will slowly drop due to lack of oxygen,The water quality will start to cloud again.The water is clear slowly,The water quality is stable,You can add a few more fish.Pay attention to the stocking density of the fish tank,There
Sewage purification treatment The so-called sewage purification treatment,The effluent quality of the treated sewage is very good,Its indicators should at least meet the above requirements for reuse,It is called sewage purification treatment.The traditional sewage treatment process is adopted,After the sewage is treated,To achieve the effect of purification treatment,The treatment process generally adopts a treatment process of three or more levels.The first-stage process is pretreatment,The second level is biochemical treatment,The third level is deep processing,Only in this way,In order to completely remove the pollutants in the sewage,The quality of the effluent reaches the level of purification.There are many pretreatment processes,Generally, depending on the water quality,The most commonly used methods are horizontal sand sink, vertical flow sand sink, Cyclone sand sink, aeration sand sink, horizontal flow sedimentation tank, vertical flow sedimentation tank, radial flow sed
