Resumo: | The sewage sludge, after being sanitized with the addition of lime, can be used to correct soil acidity and improve fertility. However, little is known about the post-liming characteristics of sewage sludge. This work was done to define the dose of lime for hygienization of sludge generated during the primary treatment of domestic sewage, determine chemical characteristics after liming, and determine application rate for use in parks and gardens. The sludge was collected from sewage drying bed of treatment Plant José Cirilo, Muriaé, MG. After sieving (2 mm mesh) an incubation curve was generated by adding different doses (0, 25, 50, 100, 150, 200 and 250 kg m-3) of hydrated lime. The data revealed that to keep the pH slightly above 12 for more than 2 h, liming dose should be 43.20 kg m3 and if this pH is to be maintained for 72 h the application rate should be increased to 71.20 kg m-3. The sludge treated at the rate of 71.2 kg m-3, was subjected to nitric-perchloric digestion to quantify total N, P, K, Ca, Fe, Na, Mg, Cr, Ni, Cd, Pb, Cu, Mn and Zn. The values, in g kg-1, were 10.08 of N, 3.63 of P, 2.80 of K, 3.16 of Ca and 52.53 of Fe, while, in mg kg-1, 268.75 of Mg, 33.50 of Ni, 2.25 of Pb, 119.75 of Cu, 499.00 of Mn and 395.50 of Zn. The Cd and Cr were not detected. |

Entretanto, pouco se conhece das características do lodo de esgoto após ter sido submetido à caleação. Por esta razão, objetivou-se, com a realização deste trabalho, definir as doses de cal para higienização de um lodo gerado no tratamento primário de esgoto doméstico, apresentar suas características químicas, após executada a caleação, além de obter as doses para aplicação em áreas de parques e jardins. O lodo analisado foi coletado no leito de secagem da ETE José Cirilo, Muriaé, MG, e após ser peneirado (malha 2 mm), foi obtida a sua curva de incubação, adicionando-se diferentes doses (0, 25, 50, 100, 150, 200 e 250 kg m-3) de cal hidratada, Ca(OH)2. Para se manter o pH ligeiramente superior a 12, por mais de 2 h após ter sido realizada a mistura, a dose de cal a ser aplicada deve ser de 43,2 kg m-3, e por 72 h deve ser de 71,2 kg m-3. Aplicada a dose de 71,2 kg m-3 no lodo, o material foi submetido à digestão nítrico-perclórico para quantificação das concentrações totais de N, P, K, Ca, Fe, Na, Mg, Cr, Ni, Cd, Pb, Cu, Mn e Zn. Os valores obtidos, em g kg-1, foram de 10,08 de N; 3,63 de P; 2,80 de K; 3,16 de Ca; e 52,53 de Fe, enquanto que, em mg kg-1, foram de 268,75 de Mg; 33,50 de Ni; 2,25 de Pb; 119,75 de Cu; 499,00 de Mn; e 395,50 de Zn.
