摘要:
To provide a reliable solid-liquid separating method and apparatus for a slurry, even though the solid component of the slurry is finely divided particles and/or of a shape difficult to entangle, without exudation through gaps in processed portions and, also, with no need to exercise a maintenance work such as replacement of filters, a solid-liquid separating apparatus includes a mold having a cylindrical inner peripheral surface, a gate for opening and closing a second open end of the mold, and a pressing rod slidable into the mold to compress the slurry. Sheet-like fibrous filters are placed on a leading end face of the pressing rod and an inner surface of the gate to seal gaps between the mold and the pressing rod and between the gate and mold. With the filters so placed, the slurry within the mold unit is compressed to provide a solidified product, thereby accomplishing solid-liquid separation.

摘要:
Chlorinated ethylene-decomposition bacteria is detected by performing PCR using nucleic acid comprising 18˜25 nucleotides that preferentially hybridizes to the 16S rRNA or rDNA of chlorinated ethylene-decomposing bacteria and has any of base sequences of SEQ ID No. 1˜15, a base sequence that has at least 90% homology with any of these base sequences, or a base sequence complementary to any of these base sequences as the primer and the nucleic acid in a sample as the template. The DNA fragment that has been synthesized is detected. Chlorinated ethylene or ethane is decomposed by introducing the chlorinated ethylene-decomposing bacteria detected by this method to contaminated soil or underground water.

摘要:
A method of and an apparatus for compressing the grinding sludge, which is effective to compress the grinding sludge to provide an intended rigid briquette even though the grinding sludge contains ground chips of hardened iron and/or steel materials and an oil-based coolant and also to facilitate reuse of the briquette (B1) as material for production of steel. The grinding sludge containing the oil-based coolant and hardened component parts such as steel component parts that are used in bearings is compressed. To this end, the grinding sludge produced from a grinding line (1) is filtered by a filtering unit (4) to provide a concentrated sludge which is subsequently compressed by squeezing by a briquetting machine (5) to provide the briquette (B1). The briquette B1 so obtained can be reused as steel material. The coolant separated from the grinding sludge during filtering and squeezing is returned to the grinding line (1) through recovery passages (7, 8).
