    摘要: A pretreatment method is provided, which comprises the following steps: (1) wastewater feed is introduced into a first end of a first aeration basin, and is mixed with a first concentrated mixed liquor to obtain a first mixed liquor; (2) the first mixed liquor is aerated in the aeration stage of the first aeration basin to obtain a second mixed liquor at a second end of the first aeration basin; (3) the second mixed liquor is introduced into a first sedimentation basin to obtain a supernatant and the first concentrated mixed liquor; (4) the supernatant is discharged and at least a part of the first concentrated mixed liquor is returned to the first end of the first aeration basin. At the same time, a sewage treatment method using the wastewater pretreatment method is provided. The pretreatment method can be used steadily for a long time without discharging sludge.

    摘要: The present invention provides a method for sludge treatment, comprising the following steps: (1) mixing a sludge feed from a sewage biotreatment process with a first mixed liquor to obtain a second mixed liquor; (2) subjecting the second mixed liquor to an oxygen-supplying process to obtain a third mixed liquor; (3) subjecting the third mixed liquor to an anoxic process to obtain a fourth mixed liquor; (4) separating the fourth mixed liquor to obtain a supernatant liquid and a first concentrated mixed liquor; (5) discharging the supernatant liquid, and returning at least a part of the first concentrated mixed liquor as the first mixed liquor to the step (1), wherein the amount of sludge of the first concentrated mixed liquor that does not return to the step (1) is less than the amount of sludge of the sludge feed. The present invention further relates to the use of the method for sludge treatment in sewage treatment. The method for sludge treatment can achieve a long term stable run without sludge discharge.

    摘要: A sewage treatment apparatus comprises a first stage equipment for treating sewage feed to obtain a first effluent and a second stage equipment for treating the first effluent to obtain a second effluent. The second stage equipment comprises a mixer (VI) for mixing the first effluent and a flocculation agent to obtain the first effluent containing the flocculation agent and a flocculation-clarification equipment (VII) comprises a first flocculation reaction chamber (A), into which the first effluent containing the flocculation agent is entered and subjected to flocculation reaction to form a mixture of water and dreg; a first separation chamber (C), into which the mixture of water and dreg from the first flocculation reaction chamber (A) is entered and separated to obtain a first part of the second effluent and a first dreg; and a second separation chamber (D), into which part of the first dreg is entered and separated to obtain a second part of the second effluent and a second dreg.
