Summary:

Rural areas in view of specyfic bulding still does has inadeguate degree solve of sewage management. Great interwals beetwen buildings and offen bad conditions to build a sewage system are cause to popularized nonconventional methods of sewage treatment in this areas. This technologis shoud be high effective, reliability and chip. These solutions permit faster achieve desirable, good to environmental ecological effects than a sewage system and local sewage treatment. The most popular in our country are constructed wetland. This constructed characterize a high effective of reduction concentrate of organic pollutions, suspended and biogenic compound, and accumulate and minaralizate secondary sludge on account of biological treatment process.
Temperature of sewage and process treatment in bed is a main factor, which significant influence on reduction pollutants in seminaturals technology of sewage treatment. In scientific literature is fault results on-site researchs of influence a winter condition on kinetic changes organic and biogenic pollutants and effectivenes reduction in this constructed. The aim of work is evaluation of influence off season vegetative on effectiveness reduction of concentrations organic and biogenic pollutants and total suspended in adjacent of sewage treatment use of reliability theory.
Influence of season on reduction analized pollutants was defined by use a statistical methods - test t-Student for small numbers of date (<30) at p<0,05 level of significant and elements of reliability theory.
Analises did not showed statistical significant different beetwen seasons for organic pollutants, total suspended and phosphate at values 0,05 level of significant. Statistical significant difference was in outflow in vertical bed for total nitrate because process of change nitrate (nitrification and denitrification) is depending of temperature sewage in bed. Low temperature cause less speed and intensity of biochemical proceses. The major reliability was in vertical bed in off season vegetative aganist vegetative season for organic and biogenic pollutants. The reliability testing carry out >99,9% for total suspended for all year. In vertical bed was highly effectiveness reduction an organic compounds and total suspended. Reliability testing was higher off season vegetative exception total suspended, where the value curry out 94,4% for vegetative season and 89,55% for off season vegetative.
