Resumen
A major problem of waste management is the disposition that can be given to
biosolids from wastewater treatment that depend on their physical, chemical and
microbiological and stabilized once they have met the necessary requirements set
on Mexican Official Standards can be used in two important ways: when Excellent
type may be in direct contact with the public, when they are only good quality can
be applied to forest uses, soil improvement and agricultural uses. The application
of biosolids is an established practice in many countries of the world, where Mexico
is no exception.
Throughout this research is a form of plasma reuse the biosolids obtained from the
Treatment Plant Wastewater Municipality of Tlalnepantla de Baz, in which they are
destined for a landfill, they are highly rich in nitrogen, carbon, phosphorus, and
therefore proposes a way to reuse rehabilitating soil with low nutrient profile
through the use of these as natural fertilizer and wheat straw using additional
additive for increasing the carbon content. This soil was characterized previously
rehabilitated subsequently performed the necessary analysis to make sure the
biosolids met all the characteristics in the NOM-004-SEMARNAT-2002, for reuse,
then proceeded to the elaboration of three mixtures containing three different ratios
of Soil, Biosolids and wheat straw. Of the identified mixtures as one, two and three,
the mixture is selected to be the three that has a greater quantity and quality of
essential molecules for soil fertilization. During the fertilization took important data
and control the behavior of mixtures for pH, temperature, humidity, Color, Odor,
total organic carbon, total organic nitrogen among others, this for a set period of
ninety days. Then perform a soil characterization after being fertilized with
biosolids.
The results show that the soil thrown greatly increased concentrations of essential
molecules as well as important elements for the development of indigenous
characteristics thereof.
Once the process is proceeded with the planting of wheat seeds in the fertilized
soil of which over a period of fifteen days, ten seeds sown grew up in this without
any anomaly. Hypothesis established, could be checked and obtained a soil high in
nutrients, in addition to sustainable use of biosolids for the benefit of agricultural
soils.
It is hoped that this research will contribute successfully in subsequent trials in
which you want to increase the level of nutrients through the use of Biosolids,
waiting and always seeking continuous improvement of the techniques developed
here to carry out the purpose of fertilization land sought.
