Diseño, construcción y automatización de un extractor de lixiviados a partir de humus de lombriz californiana (Eiseniafoetida).

Abstract

In the Tunshi Experimental Station belonging to Animal Sciences, School of ESPOCH, located at Km 10 from the Via Riobamba – Licto, Riobamba County, Chimborazo Province, designed and automated an extractor for leachates from worm humus. The experimental results obtained were subjected to the following statistical and economic analyzes mean standard deviation, variance, minimum, maximum, and the benefit/cost. The production of worm humus leachate was 5943, 63 ml/day with a minimum of 5078 ml/day, a maximum of 6000 ml/day, and a standard deviation of 178.68. The average temperature at which the organic matter was maintained during the investigation was 19,38 °C, within a minimum range of 18 °C and a maximum of 20°C with a standard deviation of 0,66 and a variance of 0,44. The average pH at which the organic matter was maintained during the investigation was 6, 78 within a minimum range of 6 and a maximum of 7, with a standard deviation of 0, 33, and a variance of 0, 11. The average humidity at which organic matter was maintained during the investigation was 80, 00%. Leachates from worm humus contain a high level of elements such as: nitrates, phosphorus, boron, potassium, calcium, magnesium, sodium, and sulfates. On the other hand, the elements that obtained a low level were: ammonium, zinc, copper, iron, and manganese; however the pH reported was neutral. The efficiency obtained in the first 10 days of leachate production is 85%. The total cost the construction of the leachate extractor from California red worm humus is $ 2847, 15; including the costs for construction, technification and labor.
