摘要： PROBLEM TO BE SOLVED: To produce, from sludge, a soil conditioner which actively proliferates dominant bacteria in sludge while sufficiently removing harmful bacteria and which is suitable to be returned to farmland. SOLUTION: A filler comprising a mixture of a magnesium compd., cellulose, and a chitin substance is filled into humus contg. dominant bacteria including bacilli and actinomyces as seed bacteria in a sludge contact vessel 60 in a sludge treating system C. Sludge is sent from a sludge circulation vessel 50 to the sludge contact vessel 60 to be brought into contact with the filler to be subjected to diffusion treatment, and then sludge in the sludge contact vessel 60 is returned to the sludge circulation vessel 50. Thus, a soil coditioner is produced from sludge.

摘要： PROBLEM TO BE SOLVED: To dispense with flow control tank for coping with the fluctuation of the amount of sewage influent, by making the tank capacity of a denitrification tank consist of a reference capacity to keep a retention time in the tank, required for a biological reaction by activated sludge in the tank, and a buffer capacity to absorb the inflow fluctuation. SOLUTION: Separated water from an aeration grit tank 2, which receives raw water 1 flowing into a system, is made to overflow to a raw water pump tank 3, the sedimented grit is discharged to a sand elimination tank 4, and the separated water is returned to the aeration grit tank 2. A denitrification tank 6, to which sewage flows from the raw water pump tank 3 through a screen tank 5, has a tank capacity consisting of a reference capacity to keep a retention time in the tank, required for a biological reaction by activated sludge in the tank, and a buffer capacity to absorb the inflow fluctuation. When the amount of the sewage flowing into a system increases, the increment is absorbed by the buffer capacity of the denitrification tank 6, and a plurality of suction pumps in a suction pump device are operated at the same time and the flow rate is increased, thereby increasing the suction amount.

摘要： PROBLEM TO BE SOLVED: To effectively utilize a hollow fiber membrane through the whole length even in long mounting span by providing a pair of end part water collecting parts and an intermediate water collecting part arranged between the end part water collecting parts and connecting plural hollow fiber membranes each having opened both ends to the water collecting parts adjacent to each other in parallel. SOLUTION: Plural hollow fiber membranes 14 are vertically separated and connected between the water collecting parts 11-13 adjacent to each other, that is between one side of the end part water collecting part 11 and the intermediate water collecting part 13, and another side of the end part water collecting part 12 and the intermediate water collecting part 13 to constitute a hollow fiber membrane unit 10. The upper end of each of water collecting parts 11-13 is respectively connected to a treated water take-out pipe 16 branched to 3 ways through a coupling 15 and a suction device 17 is connected thereto. As a result, because the length of each hollow fiber membrane 14 connecting to each water collecting part 11-13 is decreased even if the mounting span of the hollow fiber membrane unit 10 is long, the resistance loss in the hollow fiber membrane 14 is reduced and the hollow fiber membrane 14 is effectively utilized through the whole length.
