Abstract: A method for treating a plant wastewater which contains a nitrogen component and a phosphorus component in an amount insufficient for biotreatments or does not contain the components is provided in which the wastewater is subjected to anaerobic and aerobic biotreatments at a reduced cost. The method is characterized by comprising: a pretreatment step in which a plant wastewater (11) discharged from a chemical plant, petroleum plant, or petrochemical plant and containing organic compounds is introduced into an anoxic tank (1), and compounds (12) comprising a nitrogen component and a phosphorus component are added to conduct an anaerobic biotreatment; a primary treatment step in which the treated wastewater is introduced into an anaerobic biotreatment tank (2) to conduct an anaerobic biotreatment; a secondary treatment step in which the wastewater is introduced into an aerobic biotreatment tank (3) to conduct an aerobic biotreatment, and the treated water is passed through a solid-liquid separation means and discharged as secondary treated water; and a tertiary treatment step in which the secondary treated water is introduced into a reverse osmosis membrane separator (4) and separated into RO filtrate water (16) and RO concentrate water (17), at least some of the RO concentrate water (17) being returned to the anoxic tank (1).

Abstract: Intended is to provide a fine bubble-diffusing pipe capable of producing fine bubbles efficiently uniformly and homogeneously even if a diffusing pipe is elongated, and a fine bubble diffusing device and a dipped type film separating device using the fine bubble diffusing pipe. This fine bubble diffusing pipe comprises a cylindrical support pipe (1), and an elastic sheet (2) having fine slits formed therein. The elastic sheet (2) is arranged to cover the outer circumference of the support pipe (1). When the clearance between the elastic sheet (2) and the support pipe (1) is fed with a gas, the fine slits of the elastic sheet (2) are opened to perform the function to produce the fine air bubbles to the outside of the diffusing pipe. The fine bubble diffusing pipe is characterized in that the support pipe (1) has a longitudinal length (L) of 1,000 mm or more, and in that the support pipe is equipped at its two ends with gas feed portions (4) acting as gas inlet ports.

Abstract: An immersion type membrane separation apparatus having a microbubble disp ersing tube placed vertically beneath a separation membrane module, in which even when the separation membrane module is of large size, there can be att ained all-round uniform generation of microbubbles from an area vertically b eneath the separation membrane module. The apparatus comprises a separation membrane module (2) having multiple separation membrane elements each using a flat membrane as a separation membrane disposed in parallel so that the me mbrane surfaces are parallel to each other; multiple microbubble dispersing tubes (4) placed vertically beneath the separation membrane module; and mult iple gas supply tubes (5) for supplying a gas to the microbubble dispersing tubes. The multiple gas supply tubes (5) are arranged so as to be opposite t o each other across an area vertically beneath the separation membrane modul e. The multiple microbubble dispersing tubes (4) connected in communicating relationship to the gas supply tubes are arranged so as to extend in a direc tion crossing a membrane surface of separation membrane element and so as to realize proximity to each other, or superposition on each other, of the dis tal ends of the opposite microbubble dispersing tubes.

Abstract: [Object] Provided is a method of treating a plant wastewater which reduces the treatment costs of anaerobic and aerobic biological treatments on a plant wastewater containing a nitrogen component and a phosphorus component either in amounts insufficient for the biological treatments or not at all. [Solving Means] The method is characterized by including: a pre-treatment step of feeding plant wastewater 11, which contains an organic compound and is discharged from a chemical plant, a petroleum plant, or a petrochemical plant, to an anoxic tank 1, and adding compounds 12 containing a nitrogen component and a phosphorus component to the plant wastewater 11, thereby performing an anaerobic biological treatment thereon; a primary treatment step of introducing the thus treated wastewater into an anaerobic biological treatment tank 2, and performing an anaerobic biological treatment thereon; a secondary treatment step of introducing the thus treated wastewater into an aerobic biological treatment tank 3, performing an aerobic biological treatment thereon, and discharging the thus treated wastewater through solid-liquid separation means as secondary treated water; and a tertiary treatment step of introducing the secondary treated water into the reverse osmosis membrane separation unit 4 for separating the secondary treated water into RO permeated water 16 and RO concentrated brine 17. Here, at least a part of the RO concentrated brine 17 is recycled to the anoxic tank 1.
