An atom absorption spectrophotometer was used to study 13 chemical elements in samples taken at the entrance of the purification station, at the mechanical step exit, at the biostep exist, and at the laguna exit as well as following treatment of the solid fraction in open surface purification and drying plots. It was found that part of the biogenic chemical elements remained in the liquid fraction after purification and were hazardous in terms of eutrophication of the water receptacle. A technology was worked out to treat the solid fraction, however, it did not provide for preserving the biogenic chemical elements. This lowered the qualities of the fraction in enriching the soil.
使用原子吸收分光光度计研究了在净化站入口、机械步骤出口、生物步骤出口、泻湖出口采集的样本中的13种化学元素，以及在露天净化和干燥场地对固体部分进行处理后的样本。结果发现，部分生物源化学元素在净化后残留在液体部分，对水体富营养化具有危害性。研究出了一种处理固体部分的技术，然而，该技术并未考虑保留生物源化学元素。这降低了该部分在改良土壤方面的质量。
