Static experiment:
Required equipment: 1l beaker, small aeration device, micro-electrolytic filler, acid, alkali, coagulant;
Add 1 kg of packing to a 1 liter beaker and place an aeration head at the bottom of the beaker to make an aeration device. Then, the wastewater that needs to be tested is just not filled, and the aerator is turned on for aeration, and the aeration amount is adjusted to the appropriate size of the set process;
Time adjustment: The test can be carried out in several time periods such as 30 minutes, 45 minutes, 60 minutes, 90 minutes, etc.;
Adjustment of ph value: the ph value can be adjusted to 2, 3, 4, 5, 6 respectively, and the ph value of the effluent is measured;
After the reaction is finished, the waste water is poured out, and the pH is adjusted to between 8 and 9 with lime or liquid alkali to carry out flocculation precipitation (a small amount of a coagulant, such as pac may also be added), and the supernatant is taken for detection;
Dynamic experiment:
The dynamic test can be used to simulate the reactor placement on site for continuity test. The structure of the reactor can be designed according to the wastewater and the site conditions. The test parameters can be calculated as follows: the specific gravity of the filler is 1 ton / cubic meter, and the microporosity is 65%. According to the calculation of 60%, if the micro-electrolysis treatment time is 60 minutes, one cubic filler can treat 0.6 cubic meters of water per hour. If the test is processed for 30 minutes, the amount of water that can be processed per cubic meter of filler per hour is: 60/30*0.6= 1.2 cubic water; others can be deduced by analogy.
"Iron carbon filler" iron and carbon filler experiment ------ all kinds of wastewater treatment technology summary! ---186--63-64-04-92
1. Printing and dyeing wastewater: The micro-current effect and magnetic field effect between iron and carbon can cut off the chromophores of pollutants in printing and dyeing wastewater, thus decolorizing the wastewater.
2, electroplating wastewater, printed circuit board wastewater, wastewater containing heavy metal complex: the reduction of the new ecological iron ions produced by the anode can break the heavy metal complex, while using the electrophoretic effect and the coprecipitation of iron hydroxide, Reduce heavy metal complexes and wastewater cod in wastewater.
3, nitrobenzene wastewater, aniline wastewater, coking wastewater, petrochemical wastewater, hydrogen peroxide wastewater, rubber auxiliary wastewater, benzene ring chemical wastewater: 1.2v potential difference between iron and carbon can produce tiny differences between wastewater pollutants The magnetic field, the oriental movement of electrons under the action of magnetic field force will cut the carbon chain and carbon ring of the compound, thereby breaking the chain, greatly reducing the cod and improving the biodegradability of the wastewater, and converting the refractory wastewater into easy degradation. Waste water.
4. Pharmaceutical wastewater: The micro-current effect between iron and carbon can convert stable compounds in medical water into easily decomposable substances, reduce cod, and disinfect the pathogens in hospital wastewater.
5, papermaking wastewater: papermaking wastewater color is heavy, more pollutants, the current effect of micro-electrolysis, magnetic field effect and redox effect can convert long-chain fiber polysaccharides in wastewater into disaccharides or even monosaccharides, greatly Improve its biodegradability and convert it into easily degradable substances. Can be completely removed with Fenton.
6. Livestock wastewater and high-concentration organic wastewater: The micro-electrolysis effect can break the chain of high-concentration organic wastewater and destroy the chromophore group, and reduce the effect of cod, ammonia nitrogen and phosphide.

Natural Veneer is a thin sheet of wood, rotary cut, sliced or sawed from expensive natural wood. The Veneer is easy to be edge jointed and overlaid on Plywood , MDF, particleboard and so on. So, it can be used in fancy plywood, fancy MDF, fancy Blockboard and veneer faced particleboard.
Luli Group Co., Ltd, also supply engineered wood veneers with good quality and competitive pricing.
Advantages of using Natural veneers:
Compared to wood, one of the primary advantages of using veneer is stability. While solid wood can be prone to warping and splitting, because veneer is made of thin layers of wood glued together, the chances of splitting or cracking are reduced. Further, the glue used provides additional strength, making the end result stronger than natural wood.And we have Professional Natural Veneer and Natural Wood Veneer.
Usages of Natural Veneer:
Used to cover the surface of plywood, MDF, chipboard, blockboard and so on.
Specification details:
Sizes: 1220mm x 2440mm, 1250mm x 2500mm or as your request
Thickness: From 0.15mm to 0.6mm or as per request
Species: Okoume, Bintangor, Terminalia, Red hardwood, etc.
