    • The invention belongs to the technical field of environmental protection, and relates to a method for enhanced biological removal of phosphorus and nitrogen from sewage on the basis of metabolic regulation of polyhydroxyalkanoate, comprising the following steps: leading particulate organic substances obtained by primary sedimentation of sewage and excess sludge discharged from a secondary sedimentation tank into a sludge thickening tank for condensation; placing the condensed organic wastes into a polyhydroxyalkanoate precursor production reactor to synthesize polyhydroxyalkanoate precursors through anaerobic fermentation; after removing nitrogen and phosphorus, pumping the liquid into a polyhydroxyalkanoate precursor reservoir; pumping the polyhydroxyalkanoate precursors into a polyhydroxyalkanoate production reactor to produce polyhydroxyalkanoate; pumping into a conventional bioreactor for removal of phosphorus and nitrogen from sewage to conduct a process for biological removal of phosphorus and nitrogen from sewage. The present invention raises the removal rate of nitrogen and phosphorus up to around 80% to 95%, and the treated effluent water attains to the requirement of the Grade 1A discharge standard for sewage treatment plants. The method has the advantages of easy-to-control processes, low greenhouse gas emissions and reduced sludge production, and low cost of technical renovation and the like.

    • The key part of a guide float valve plate--the float valve is disclosed. The object of the invention is to provide a parent-subsidiary guide float valve which has small pressure drop, high plate flux, high operation flexibility and can maintain high efficiency within a wide change range of the gas phrase load. The technical proposal of the invention is that: a parent-subsidiary guide float valve, of which the parent valve is a plane configure which is symmetrical with axial line thereof, the axial line directs toward overflow weir along the liquid flow, and the parent valve has at least two valve legs, the front valve leg length is longer than the back valve leg length, and when the parent valve is completely opened, an included angle of 2-10 degrees between valve cover and valve hole plate is opened toward overflow weir, while there is a valve hole on the parent valve with a subsidiary valve thereon, said subsidiary valve is a float valve with its area is small than that of the parent valve and its surround is paralleled with that of the parent valve, said subsidiary valve also has at least two legs, the front valve leg length is equal to or longer than the back valve leg length, when said subsidiary valve is completely opened, an included angle of 0-10 degrees between the subsidiary valve and the parent valve is opened toward overflow weir.

    • This invention relates to a process of integrated system formed by coupling of fixed bed, jetting floating bed, and separating unit, aimed to provide a new process and equipment of higher efficiency, which integrates multi-type reactors and separation. In this invention, reaction materials will undergo preliminary reaction in fixed bed reactor and intensified reaction in jetting floating bed reactor, and then separation in the subsequent separation system. Unreacted materials will be returned to the raw material intermediate storage tank for mixing with fresh materials, as raw materials for continued reaction. During this process, materials first pass the fixed bed reactor once to achieve certain conversion rate, and then enter the jetting floating bed reactor for intensified reaction. When the product reaches required concentration, the materials will enter subsequent separation equipment for separation. During the whole process, fixed bed reactor, jetting floating bed reactor, and subsequent separation system are coupled, so that the flow path is more integrated, reaction time is greatly shortened, and process energy consumption is further lowered.
    • 本发明涉及通过固定床的耦合,喷射浮床,和分离单元上综合系统,目的在于提供高效率,它集成了多类型的反应器和分离的新工艺和设备的处理。 在本发明中,反应材料将发生固定床反应器预反应并加剧了在随后的分离系统的喷射浮床反应器中,然后分离反应,未反应的材料将被返回到原料中间储罐与新鲜材料混合, 作为用于持续反应的原料。 在此过程中,材料先通过固定床反应器一旦达到一定的转化率,然后进入喷射浮床反应器,用于增强反应。 当产物达到所需的浓度,该材料将进入随后的分离设备进行分离。 在整个过程中,固定床反应器,喷射浮床反应器中,和随后的分离系统被耦合,所以没有流动路径是集成度更高,反应时间大大缩短,而且过程的能量消耗进一步降低。
