摘要： Disclosed is an invention providing an improved method to treat a factory waste, and more particularly for the treatment of pectic waste fluids from orange canneries i.e. the acid- and alkaline wastes. The present invention also provides a process to recover pectic substance therefrom. The method contains the steps of (1) adjusting the pH either in the acidic waste or a mixture of acidic- and alkaline waste to a level over 7.0, allowing the waste or mixture to stand for a period sufficient to effect a substantial saponification of the pectic constituent, adding acid to the waste or mixture to bring its pH below 3, separating the pectic substance from the resultant, and treating the resultant supernatant or filtrate by a biological procedure using an active microorganism, or, alternatively, (2) adding acid to the alkaline waste to bring its pH below 3, separating the pectic substance from the resultant, and treating the resultant supernatant or filtrate by a biological procedure using an active microorganism. The resulting high-quality pectic product is advantageously usable in various food products, cosmetics or medicines.
