””””MECHA-CERA water treatment technology is the introduction of Japan's high-tech water treatment technology and its operating principles are : the aqueous solution containing low concentrations of sodium metal in catalytic devices, ceramic catalytic catalytic oxidation reactions occur, producing a strong oxidation of reactive oxygen-based, high-oxidation and formation of a reactive catalytic oxidation water; Water and sewage oxidation catalyst will be mixed oxide contained organic and inorganic decomposition of sewage to Difenzi, and drug-free, and thus achieve the purpose of dealing with sewage purification.
Reaction formula : NaOCl ”ś Na + £« Cl - £«©zO©{

Characteristics :
catalytic long useful life : metal ceramic catalyst is Fe/Mn/Co of metal compounds as the main component, added 18 species of metal oxide powder, mixed with a certain ratio in 1600 produced high temperature ceramics, sinter shaped small ball. Catalytic metal oxides will not dissolve in NaOCI solution, and therefore its capacity and performance before and after contact with NaOCI always the same, but not direct contact wastewater, catalytic surface is not easy dirty, so long as they adhere to the annual regular cleansing second (each no more than 2 hours), permanent use.
Simple requests for water, the application scope : oxide is a strong base of single oxygen and sewage oxidation reduction reaction to the material, the pH value of sewage, no temperature requirements, and there is no need to regulate pH values and temperature. Since the introduction of oxidation reduction reaction treatment, and oxidation nature, contained in the sewage are inorganic and organic, it is difficult for them and biodegradable material has very good results can also reduce Cod, BOD, SS, chroma, n-Hexane, T-N, T-P, ABS and smell.
Save manpower and resources, the operating cost : MECHA-CERA sewage systems need only a small amount of the operation process of sodium, pH value adjustment required at the beginning, no cooling system, no chemical residues, and sewage systems operate MECHA-CERA simple, smooth operation, the savings in material and human resources, operating costs only 10% of traditional crafts.
For the textile wastewater treatment effect Merit : Since printing high-temperature, high organic matter content, contain many difficult decomposition material (TPA,EG etc.), it is difficult to deal with. MECHA-CERA sewage treatment system and the catalytic oxidation of water oxidation nature, and the textile wastewater mixed reaction to break down the material so that after the conversion occurred, the follow-up to the degradation of biological treatment processes to improve the efficiency of microbial treatment to achieve wastewater discharge emissions.
