摘要： High impact resistant thermoplastic resins are produced in three steps: (a) graft polymerizing a minor amount of unsaturated monomer onto a major amount of diene type rubber polymer in latex form, (b) mixing the grafted diene type rubber latex with a monomer or monomers, extracting the grafted rubber polymer particles into the monomer phase and separating and discarding the water phase to obtain a grafted rubber polymer particle dispersed monomer solution, and (c) bulk polymerizing the resulting rubber polymer particle dispersed monomer solution.

摘要： A solid-liquid separation apparatus wherein a solid-liquid mixture is introduced into a rotary filtration drum having filter cloth mounted thereon and is allowed to pass through the filter cloth to thereby separate the solids contained therein. The filter cloth has one surface facing the interior of the drum and covered with a napped filter layer which is formed by a multiplicity of fibers having a diameter of 0.1 to 10 .mu.m. The filter cloth preferably has an elongation percentage of not smaller than 1.0%. A base material of the filter cloth includes a weft extending along the rotational axis of the drum and a warp extending in the circumferential direction of the drum. The fibers of the napped filter layer are formed by napping chiefly the weft in the direction of the warp. A first sprayer is arranged in a facing relation to the outer peripheral surface of the filter cloth, for flushing a collecting liquid to collect the solids arrested by the filter cloth, and a collecting hopper is arranged inside the drum, for collecting the solids washed off by the collecting liquid. A second sprayer is arranged in a facing relation to the inner peripheral surface of the filter cloth, for flushing a washing liquid to wash off the solids attached to the fibers of the napped filter layer. Further, a third sprayer is arranged outside the drum for washing the filter cloth with chemicals, and a baffle plate is arranged inside the filtration drum.

摘要： A solid-liquid separation element which remarkably, improves the solid-liquid separation capacity of a solid-liquid separation device having the separation element therein is provided. In this separation element, guide members for accelerating the through-flow of the liquid are mounted on the back surface of a stationary inclined screen and, optionally, guide members for transporting solid materials are arranged on the surface of the screen so as to be substantially in parallel to each other and in a downward inclining direction from both edges of the screen. The solid-liquid separation apparatus having said separation element and a cleaning brush which is reciprocated in rubbing contact with the back surface of the screen is also provided. The range of the reciprocating motion of the brush is more than the width of the screen.

摘要： The device according to the present invention comprises a unidirectionally circulating endless filter cloth with a napped filter layer on the surface, a solid-liquid mixture supply device installed on the front side of filter cloth, a depressurizing suction device installed on the backside of the filter cloth, a non-filterable content withdrawing device installed downstream of the solid-liquid mixture supply device and the depressurizing suction device, and a filter cloth wash device installed downstream of the non-filterable content withdrawing device in the running direction of the filter cloth and located between the non-filterable content withdrawing device and the solid-liquid mixture supply device or the depressurizing suction device. The depressurizing suction device is equipped with a depressurized suction port splaying in the running direction of said filter cloth. The depressurized suction port is equipped with at least one group of filter cloth guide rolls on the right and left sides in the running direction of filter cloth. The filter cloth guide rolls which constitute the right of left group spread outwardly in the running direction of filter cloth. The present device can minimize damage to the filter cloth by the depressurizing suction device without decreasing the solid-liquid separation performance and thus drastically prolong the service life of the filter cloth.

摘要： A method for biologically purifiying waste water which produces substantially no excess waste sludge is provided. In this method, a waste water containing biodegradable substances is treated in a biological fixed film type reactor and aqueous water sludge discharged from the reactor is aerobically digested after being separated from the biologically treated waste water. The digested aqueous sludge is returned to the reactor or the upstream thereof. This method can be advantageously combined with any installed activated sludge type water purification process, to thereby substantially eliminate the production of excess waste sludge from the water purification system.
