Abstract
<p>The research is aimed to study on the applicability of VFCW technology by using Biochar-soil mixing as growing materials of Cyperus and Typha for treating wastewater containing formaldehyde as produced through the production processes of ethylene oxide and ethylene glycol that belonging to TOC Glycol Company inside Mabtaput Industrial Estate in Eastern Thailand. The results found that VFCW technology in form of small experimental unit of Lysimeter was applicable together with Cyperus Biochar:Soil Ratio of 1:50 and planting Cyperus. The application of formaldehyde wastewater flow rate 100 ml/min was shown highest potential for having breakthrough point at 20 liters, HRT 6.67 hours, formaldehyde effluent quality 1.03 mg/L (influent 20 mg/L) treatment efficiency 94.85% and encouraging the aquatic plants in highest numbers up to 140 stems of Cyperus as the same as more <em>Pseudomonas</em> sp. 1.8x10<sup>5</sup> CFU/g.soil for better decomposers of formaldehyde wastewater.<strong></strong></p>

Industrialization is acceptable tool for economic and social development in order to increase the national income and the gross national product (GNP) excluding the main income from limiting-good lands for cultivating crops and bringing up livestocks in the whole kingdom of Thailand
The tentative research plan will be designated for 4 issues in which the methods will be as follows: firstly, treatment efficiency of two-consecutive oxidation ponds; secondly, Biochar preparation; thirdly, vertical flow constructed wetland (VFCW) lysimeter construction; and determination of effluent odor treatment efficiency; the details will be as the followings: 2.1 Treatment Efficiency of Two-Consecutive Oxidation Ponds
total organic carbon (TOC) Glycol company is located inside Mabtaput Industrial Estate (MIE) in Eastern Thailand which has been confronted with formaldehyde odor problem as obtain from production processes of ethylene oxide and ethylene glycol
Summary
Industrialization is acceptable tool for economic and social development in order to increase the national income and the gross national product (GNP) excluding the main income from limiting-good lands for cultivating crops and bringing up livestocks in the whole kingdom of Thailand. The factory wastes have been spread out in form of hazards, chemical wastewater, volatile organic compounds (VOCs), smokes, aerosols, dusts together with contaminant air and effluents It is lucky for Thailand as located in tropical climate which belongs to more amount and long-period rainfall and high vapor pressure, certainly wind speed and direction, plenty of sunshine and insulation, and greenery coverage, that can be burdensome for relieving such environmental problems. The government has paid more attention on promotion of industrial factories for oil refinery, chemicals, textiles, paper, wood-glue production, plastics, community garbage composting, and para rubber processing Their industrial activities utilize formaldehyde as a key chemical in organic synthesis of special chemicals such as pentaerythritol and ethylene glycol, synthetic resins, paper production, medicinal products and drugs, and others, too numerous to mention. Formaldehyde (gases and effluent) is functioned on precursors and on toxic wastes from using for chemical, textile, plastic, cosmetics, www.ccsenet.org/mas
