Abstract
"PROCESSO DE SOLIDIFICAçãO E INERTIZAçãO DE LODOS COM MATERIAIS GRANULARES E AGLOMERANTES". Refere-se a presente patente de invenção a um inédito processo de solidificação e inertização de lodos com materiais granulares e aglomerantes, para uso nos aterros sanitários, que recebem resíduos dos mais variados tipos, como domiciliares e industriais onde o processo consiste da mistura do lodo, com materiais granulares como areia, argila, saibro e outros, além de utilizar cal virgem e cimento portland como aglomerantes, podendo esta mistura ser com um só material granular e aglomerante ou uma variação do mesmo, conforme a necessidade de solidificação do lodo, que possui grande variação de consistência e de características físico-químicas. O produto gerado tem as características de ser, não poluidor, solidificado, sendo utilizado como aterro pelo fato da resistência da massa final suportar uma pressão que varia entre 0,3 a 1,0 kg/CM^ 2^ objeto da presente patente de invenção."PROCESS FOR SOLIDIFICATION AND INERTIZATION OF SLUDGE WITH GRANULAR MATERIALS AND AGGLOMERANTS". The present patent refers to an unprecedented process of solidification and inertization of sludge with granular materials and binders, for use in landfills, which receive residues of various types, such as household and industrial where the process consists of mixing sludge. , with granular materials such as sand, clay, gravel and others, in addition to using virgin lime and portland cement as binders, which may be a single granular material and binder or a variation thereof, depending on the need for solidification of the sludge, which It has a wide range of consistency and physicochemical characteristics. The generated product has the characteristics of being non-polluting, solidified, being used as landfill because the resistance of the final mass withstands a pressure ranging from 0.3 to 1.0 kg / CM ^ 2 ^ object of the present invention. .
