Embodiment 1

[0024] A method of using microorganisms to treat sewage, comprising the steps of:

[0025] (1) After crushing chestnut shells and camellia oleifera shells with a mass ratio of 2:1, make phosphoric acid into a solution with a mass concentration of 5-10% to soak chestnut shells and camellia oleifera shells for activation for 2 hours. The amount of phosphoric acid added is 2% of the total amount of chestnut shells and camellia oleifera shells were carbonized at a temperature of 850°C for 24 hours to obtain an adsorbent.

[0026] (2) Pulverize apple snails, camellia oleifera cake, and sugarcane filter mud respectively and put them into a mixing tank, then add molasses, peptone and water; after stirring evenly, keep warm at 100°C for 60 minutes, and cool to obtain microbial nitrogen source; The mass ratio of Fushou snail, camellia oleifera cake, sugarcane filter mud, molasses, peptone and water is 1:2:5:0.5:1:10.

[0027] (3) Micrococcus luteus, Frankia, nitrous acid oxidizing bac...

Embodiment 2

[0032] A method of using microorganisms to treat sewage, comprising the steps of:

[0033] (1) After pulverizing chestnut shells and camellia oleifera shells with a mass ratio of 3:1, make phosphoric acid into a solution with a mass concentration of 5-10% to soak chestnut shells and camellia oleifera shells for activation for 1 hour. The amount of phosphoric acid added is 3% of the total amount of chestnut shells and camellia oleifera shells were carbonized at a temperature of 900°C for 20 hours to obtain an adsorbent.

[0034] (2) Pulverize apple snails, camellia oleifera cake, and sugarcane filter mud respectively and put them into a mixing tank, then add molasses, peptone and water; after stirring evenly, keep warm at 110°C for 40 minutes, and cool to obtain microbial nitrogen source; The mass ratio of Fushou snail, camellia oleifera cake, sugarcane filter mud, molasses, peptone and water is 1:2:5:0.5:1:10.

[0035] (3) Micrococcus luteus, Frankia, nitrous acid oxidizing b...

Embodiment 3

[0040] A method of using microorganisms to treat sewage, comprising the steps of:

[0041] (1) After crushing chestnut shells and Camellia oleifera shells with a mass ratio of 1:1, make phosphoric acid into a solution with a mass concentration of 5-10% to soak chestnut shells and Camellia oleifera shells for 1 hour of activation. The amount of phosphoric acid added is 3% of the total amount of chestnut shells and camellia oleifera shells were carbonized at a temperature of 800°C for 24 hours to obtain an adsorbent.

[0042] (2) Pulverize apple snails, camellia oleifera cake, and sugarcane filter mud respectively and put them into a mixing tank, then add molasses, peptone and water; after stirring evenly, keep warm at 120°C for 30 minutes, and cool to obtain microbial nitrogen source; The mass ratio of Fushou snail, camellia oleifera cake, sugarcane filter mud, molasses, peptone and water is 1:2:5:0.5:1:10.

Abstract

The invention discloses a method for treating sewage by using microorganisms. The method comprises the following steps: pulverizing chestnut shells and camellia oleifera shells, adding phosphoric acid, activating, and carbonizing to obtain an adsorbent; respectively crushing pomacea canaliculata, the oil tea cake and the sugarcane filter mud, adding into a stirring tank and adding molasses, peptone and water to prepare a microbial nitrogen source; mixing micrococcus luteus, frankia, nitrite oxidizing bacteria, coriolis palustris, bacillus subtilis and EM bacteria to obtain a compound bacteriasolution; uniformly mixing chitosan, sodium alginate, talcum powder and redispersible latex powder to prepare a biological carrier; and uniformly mixing the composite bacterial liquid and the microbial nitrogen source, culturing, adding the adsorbent and the biological carrier, uniformly stirring, and drying to obtain the microbial sewage treatment agent. The microbial treatment agent prepared bythe method can effectively remove ammonia nitrogen, heavy metal ions, COD and the like in sewage and is relatively low in investment cost and has a very good application prospect in sewage treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for treating sewage with microorganisms. Background technique [0002] With the advancement of urbanization and the rapid development of industry, the problem of environmental pollution is becoming more and more serious. A large amount of domestic and industrial sewage flowing into rivers, lakes or groundwater will cause serious pollution to water bodies and negatively affect the health and safety of residents. Among them, industrial sewage contains many pollutants and has complex components. It is not only difficult to purify in water, but also difficult to treat. It is an urgent problem to be solved in today's environmental pollution problems. [0003] The pollutants in industrial sewage are mainly ammonia nitrogen, phosphorus, sulfide, inorganic salts and other substances. Ammonia nitrogen is an important pollutant that causes eutrophication of water bodies ...
