Example Embodiment

[0064] Example 1: Step 1) Sewage enters the anaerobic tank. The anaerobic tank contains GPB active carrier and active biological protein. The GPB active carrier accounts for 25% of the water volume in the anaerobic tank. The GPB active carrier is made of polyurethane water-absorbing gel Porous gel-like carrier; put activated sludge into the anaerobic tank, the input amount of activated sludge is 5-10% of the volume of water in the anaerobic tank, and the input amount of active biological protein is 0.02%-0.03% of the mass of activated sludge, The anaerobic tank makes the GPB active carrier flow through the stirring motor;

[0065] Step 2) The sewage processed by the anaerobic tank enters the sedimentation tank one;

[0066] Step 3) The sewage passing through the sedimentation tank 1 enters the aerobic tank. The anaerobic tank contains ACD active carrier and active biological protein; the ACD active carrier accounts for 25% of the volume of the water in the anaerobic tank, and the A...

Example Embodiment

[0111] Example 2: A sewage treatment method using a fluidized microbial bed and a filter membrane. The difference from Example 1 is that the active biological protein includes 38 parts by weight of buckwheat protein biologically active peptide, 12 parts of fish skin collagen, and bone meal. 5 servings.

Example Embodiment

[0112] Example 3: A sewage treatment method using a fluidized microbial bed and a filter membrane. The difference from Example 1 is that the active biological protein includes 20 parts by weight of buckwheat protein biologically active peptide, 27 parts of fish skin collagen, and bone meal. 6 servings.

Abstract

The invention provides a sewage treatment method by using a flowing microorganism bed and a filtering membrane. The method comprises the following steps: the step 1), discharging the sewage into an anaerobic pool, wherein the anaerobic pool has GPB active carriers and active bioproteins, and the GPB active carriers are 25-72% of the volume of the water body in the anaerobic pool, feeding activated sludge and the active bioproteins into the anaerobic pool, and enabling the GPB active carriers to be flowed in the anaerobic pool by a stirring motor; the step 2), discharging the sewage treated by the anaerobic pool into a sedimentation basin I; the step 3), discharging the sewage passing through the sedimentation basin I into an aerobic pool, wherein the aerobic pool has ACD active carriers and the active bioproteins; feeding the activated sludge and the active bioproteins into the aerobic pool, performing the aeration to the aerobic pool so as to enable the ACD active carriers to be flowed; the step 4) feeding the sewage passing through the aerobic pool into a sedimentation basin II, and discharging; and the step 5), filtering the dyeing sewage discharged from the sedimentation basin II by a porous ceramic membrane.

Description

technical field [0001] The invention relates to industrial wastewater treatment, in particular to a sewage treatment method utilizing a flowing microbial bed and a filter membrane. Background technique [0002] All kinds of wastewater are produced in the textile industry, among which the pollution of printing and dyeing wastewater is relatively serious, and its discharge accounts for about 1 / 10 of the total discharge of industrial wastewater. In my country, about 600-700 million tons of printing and dyeing wastewater are discharged into the water environment every year. One of the most important sources of water pollution, so the treatment of printing and dyeing wastewater has become an urgent problem to be solved. [0003] Printing and dyeing wastewater is mainly composed of desizing wastewater, boiling wastewater, bleaching wastewater, mercerizing wastewater, dyeing wastewater, soaping wastewater and printing wastewater. It is characterized by complex components, high chro...
