摘要： A process for treating organic wastewater which comprises treating organic wastewater with ozone and successively with alkali and introducing said alkali treated organic wastewater into an anaerobic digestion tank for anaerobic digestion. Instead of the ozone and successive alkali treatments, ozone treatment in the presence of hydrogen peroxide or ozone treatment under UV radiation is applicable. Prior to introduction into the anaerobic digestion tank, the treated wastewater may be separated into solids and phosphorus is preferably recovered from the solution. Solubilization of solids in the organic wastewater and transformation of organic substances into methane are greatly enhanced and sludge to be disposed is greatly reduced. Moreover, phosphorus is efficiently eluted out and recovered from solids in the organic wastewater.

摘要： A sludge treatment method allowing an improvement in a phosphorus recovery rate and sludge volume reduction by efficiently eluting phosphorus in the sludge. The sludge treatment method includes: a step of foaming a sludge-containing liquid by blowing an ozone-containing gas into the sludge-containing liquid; and a step of eluting phosphorus in the sludge-containing liquid by bringing sludge adsorbed on bubbles and a sludge-dissolving agent into contact with each other. The sludge treatment method may further include the steps of: separating the phosphorus eluted sludge-containing liquid into a phosphorus eluate and a residual sludge; and precipitating a phosphorus compound by adding a coagulant to the separated phosphorus eluate.

摘要： In a process of eluting phosphorus from sludge into a liquid phase and recovering the phosphorus efficiently, cell walls of microorganisms in the sludge are ruptured by a process selected from crushing sludge (for example, treating with an ultrasonic wave homogenizer), treating with ozone, and treating with heat. Then the liquid phase is treated with alkali, thereby eluting the phosphorus into a liquid phase efficiently in a short time. By coagulating and precipitating, the phosphorus eluted into the liquid phase is recovered.
