Embodiment 1

[0028] A system for treating sewage with microorganisms, comprising:

[0029] Pretreatment unit for settling suspended solids, inorganic particles and other particulate matter of sewage;

[0030] The anaerobic microbial treatment unit uses anaerobic microorganisms to further treat the sewage and degrade the refractory organic matter in the sewage;

[0031] The aerobic microbial treatment unit uses aerobic microorganisms to further treat the sewage and degrade the degradable substances in the sewage;

[0032] The biofilm filter unit adopts biofilm to filter the sewage treated by the above treatment unit.

[0033] The pretreatment unit, the anaerobic microorganism treatment unit, the aerobic microorganism treatment unit and the biofilm filter unit are sequentially connected, and a fiber mesh filter device is arranged between the pretreatment unit and the anaerobic microorganism treatment unit, and the anaerobic microorganism A fiber mesh filter device is arranged between the t...

Embodiment 2

[0037] A method for treating sewage with microorganisms, comprising the steps of:

[0038] 1) Sewage pretreatment: Sewage enters the pretreatment unit, adding microbial flocculant and magnetic powder, stirring at a speed of 50-100r / min and then standing still until the suspended matter, insoluble organic matter, inorganic particles and other particles in the sewage are completely settled ;

[0039] 2) Fiber mesh filtration treatment: filter the pretreated sewage through fiber mesh to remove suspended solids, insoluble organic matter, inorganic particles and other particles;

[0040] 3) Anaerobic microbial treatment: Heat the filtered sewage to 30-40°C and maintain a constant temperature, adjust the pH value to 7-7.5, put in anaerobic microorganisms, stir at a speed of 50-100 r / min after standing for reaction, and then Let stand until all impurities settle;

[0041] 4) Aerobic microbial treatment: After the sewage treated by anaerobic microorganisms is naturally filtered by f...

Embodiment 3

[0047] Get the untreated industrial sewage 1000kg of a certain printing and dyeing factory, adopt the microbial control method of the present invention:

[0048] 1) Sewage pretreatment: 1000kg of sewage enters the pretreatment unit, add 3kg of microbial flocculant and 0.5kg of magnetic powder, stir at a speed of 50-100r / min for 0.5h, and then stand still for 1.5-2h until the suspended solids in the sewage are completely settled , insoluble organic matter, inorganic particles and other particles;

[0049]2) Fiber mesh filtration treatment: filter the pretreated sewage through fiber mesh to remove suspended solids, insoluble organic matter, inorganic particles and other particles;

[0050] 3) Anaerobic microbial treatment: heat the filtered sewage to 30-40°C and maintain a constant temperature, put in anaerobic microorganisms (including denitrifying bacteria, Bacteroides fragilis, Fusobacterium nucleatum, and anaerobic Gram-negative bacilli), statically After the reaction, stir...

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a system and method for treating sewage by using microorganisms. The system comprises: a pretreatment unit, an anaerobic microorganism treatment unit, an aerobic microorganism treatment unit, and a biofilm filtration unit, wherein the pretreatment unit is used for sedimentation of suspended solids, insoluble organic matters, inorganic particles and other particles in the sewage, anaerobic microorganisms are used to further treat the sewage to degrade hardly degradable organic matters in the sewage through the anaerobic microorganism treatment unit, aerobic microorganisms are used to further treat the sewage to degrade degradable substances in the sewage through the aerobic microorganism treatmentunit, and a biofilm is used to filter the sewage treated by the above treatment units through the biofilm filtration unit. The efficient degradation of micro-pollutants in the sewage is realized through filtration of the microorganisms and the biofilm, the problem that residual micro-pollutants still exist in the water resource treated in the prior art is solved, a good and sustainable-operation sewage treatment system can be formed, and the effects of deodorization, decolorization, turbidity removal, nitrogen and phosphorus removal, and pollutant removal can be realized.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a system and a treatment method for treating sewage by using microorganisms. Background technique [0002] Sewage refers to the general term for the water discharged during residents' activities and runoff rainwater, which includes domestic sewage, industrial wastewater, and other useless water such as primary raintrack flowing into drainage pipes and channels. my country's water resources have been facing the problem of resource scarcity and uneven regional distribution. The per capita water resources are relatively low. It is one of the countries with poor per capita water resources in the world. It is also facing serious water pollution, which restricts the social economy. With the development and improvement of people's living standards, at present, the purification methods of water resources include physical methods, chemical methods, biological methods a...
