摘要： The present invention relates to a technology which can efficiently concentrate a suspension liquid which needs to be concentrated in sewage treatment plants or various waste water treatment plants, particularly sludge or the like which contains a large amount of odor components which will adversely be decayed and is hard to concentrate. The present invention can prevent odor substances from being produced in a concentration process, and can remarkably reduce the amount of odor components, carbonic acid, and the like contained in concentrated sludge or a lower separated liquid. Specifically, in a process of concentrating or dewatering residual evaporated substances in a liquid, when sludge is held under a reduced pressure of 5 to 70 kPa for less than 15 minutes, a portion of gas components dissolved in the liquid is changed into gaseous phase, and activation of microorganisms in the liquid is restricted. After a decompressing process is performed under the reduced pressure, the liquid is introduced into a gravity concentration tank for gravity concentration, or the decompressed liquid or the gravity-concentrated sludge is introduced into a flocculation reaction tank for flocculation, and is then dewatered by a dewatering device.
摘要翻译：本发明涉及一种能够有效地浓缩需要浓缩在污水处理厂或各种废水处理厂中的悬浮液的技术，特别是含有大量会恶化的气味成分的污泥等，很难集中精神本发明可以防止在浓缩过程中产生气味物质，并且可以显着地减少浓缩污泥或较低分离液体中所含的气味成分，碳酸等的量。具体地说，在使液体中的残留蒸发物质浓缩或脱水的过程中，当污泥在5〜70kPa的减压下保持少于15分钟时，溶解在液体中的部分气体成分变为气相，液体中微生物的活化受到限制。在减压下进行减压处理之后，将液体引入重力浓缩池中进行重力浓缩，或将减压液体或重力浓缩污泥引入絮凝反应槽中进行絮凝，然后通过脱水装置

摘要： The present invention provides a concentration type aggregation reaction apparatus having a concentration screen, which enables an aggregation reaction to be conducted in sludge and the sludge to be concentrated by separation of a liquid by means of a single apparatus. The concentration screen is in a cylindrical form and includes slits having horizontal openings. A decelerating device is connected to an upper portion of a shaft for an agitator for agitation in the tank and brushes are connected to the decelerating device. The brushes are adapted to revolve along opposite surfaces (on a primary side and a secondary side) of the screen. By use of these brushes, aggregates adhered to the screen are continuously removed.
