Advantageous effects
The invention provides a manufacturing method of a municipal sewage treatment and deodorization system. The method has the following beneficial effects:
(1) according to the manufacturing method for the municipal sewage treatment and deodorization system, the amine (organic nitrogen), ammonia nitrogen and ammonium salt are directly absorbed by the soil bacteria Bacillus through the microbial flora in the JS-BC device and are utilized by microorganisms, so that nitrogen removal is performed, nitrogen elements enter sludge in the form of organic nitrogen, are removed from the system through the discharge of excess sludge, and are converted into nitrogen to be discharged into air. The soil bacteria Bacillus belongs to gram-positive bacteria, compared with gram-negative bacteria, the cell wall of the gram-positive bacteria is thicker and more uniform than the cell wall of gram-negative bacteria (bacteria used in a common activated sludge process), and peptidoglycan is connected through peptide bonds to form the cell wall. The cell wall of gram-positive bacteria contains a large amount of teichoic acid. That is, in the synthesis reaction of microorganisms, phosphate enters the cell wall of the soil bacteria Bacillus in the form of teichoic acid, and finally phosphorus is removed from the system through the discharge of excess sludge. The soil bacteria Bacillus can absorb and absorb nitrogen in sewage in an ammonia NH state before oxidation in a short time, and part of the absorbed and absorbed nitrogen is used as nutrient during proliferation. Biologically, the uptake of phosphorus is at a maximum at a dissolved oxygen concentration of 0.5 mg/l. However, one of the best growth conditions of the soil bacteria (Bacillus) is that the dissolved oxidation concentration in the aeration tank is 0.1-1.2 mg/l, and the two conditions are consistent, so phosphorus can be effectively removed, the phosphorus removal rate is generally over 80% by the soil bacteria Bacillus, and the water quality treatment is carried out on the sewage by matching with a decarburization BAF and a denitrification BAF system, so that the aim of high removal rate of carbon, nitrogen and phosphorus elements in the sewage is fulfilled.
(2) According to the manufacturing method for the municipal sewage treatment and deodorization system, soil bacteria (Bacillus) have the capability of instantly absorbing and decomposing odor under the action of the soil bacteria in the JS-BC device, and the odor can be inhibited when sewage is treated by the JSBC process. Therefore, the odor problem which troubles sewage treatment facilities can be satisfactorily solved. Because the soil bacteria Bacillus has deodorization capability, sludge and odor are basically not generated in the treatment process of the JSBC process; meanwhile, in the process of the grit chamber and the secondary sedimentation chamber, the plant deodorant is atomized and sprayed on the sewage, so that the atomized plant extracting solution molecules can be uniformly dispersed in the air to adsorb the peculiar smell molecules in the air, and the peculiar smell molecules are subjected to chemical reactions such as dispersion, polymerization, substitution, replacement and synthesis or are subjected to catalytic reaction with oxygen in the air, so that the peculiar smell molecules are changed, the original molecular structure is changed, and the peculiar smell is lost. The final products of the reaction are H2O, oxygen, nitrogen and other harmless molecules, so that the aim of efficiently deodorizing the finally discharged sewage is fulfilled.

the fifth step: the effluent of the superfine grating automatically flows into a mixed water distribution tank, nutrient solution is added into the effluent in the mixed water distribution tank, and the mixed sewage flows into a JS-BC device;
and a sixth step: the effluent in the JS-BC device flows into an aeration tank, an air blower supplies air to the aeration tank, a pump for returning the effluent of the aeration tank is arranged at the tail end of the aeration tank, and the sewage flows back to a mixed distribution tank and the air blower supplies air to the aeration tank, so that the dissolved oxygen in the aeration tank is kept;
the seventh step: effluent in the aeration tank flows into a secondary sedimentation tank, sludge and water in the secondary sedimentation tank are separated, sludge in the secondary sedimentation tank flows back to the mixed distribution tank through a sludge reflux pump, and residual sludge in the secondary sedimentation tank is pumped to a sludge treatment system for treatment;
eighth step: the effluent of the secondary sedimentation tank flows into a decarburization BAF automatically, most of organic pollutants, part of ammonia nitrogen and part of total phosphorus are removed from the decarburization BAF, the effluent of the decarburization BAF automatically flows into a denitrification BAF, the ammonia nitrogen is further removed from the denitrification BAF, and most of the ammonia nitrogen is converted into nitrate;
the ninth step: and the water after the decarburization BAF and the denitrification BAF enters an ultraviolet disinfection system and is discharged through a water outlet metering well.
2. The method of claim 1, wherein the deodorizing system for municipal sewage treatment comprises: and in the third step and the seventh step, at least four atomizing nozzles are arranged on the side walls of the grit chamber and the secondary sedimentation tank, and are used for spraying a pure natural plant extracting solution for sewage deodorization.
3. The method of claim 1, wherein the deodorizing system for municipal sewage treatment comprises: in the fifth step, the volume ratio of the nutrient solution to the inlet water is 1: 0.00000005-1: 0.00000007, and the nutrient solution mainly comprises tropical fresh fruits, edible alcohol and pure spring water.
4. The method of claim 1, wherein the deodorizing system for municipal sewage treatment comprises: and in the fifth step, the JS-BC device comprises a biological reaction tank and a reticular rotary flora contact body device, a microbial film is attached to the contact body, air is supplied in the JS-BC device through an air blower, and sewage is adsorbed and preliminarily degraded by soil bacteria Bacillus growing on a carrier in the JS-BC device.
5. The manufacturing method of the municipal sewage treatment deodorization system according to claim 1, wherein in the sixth step, the blower supplies air to the aeration tank, and the air pipe valve is adjusted to maintain the dissolved oxygen content in the aeration tank at 0.1-1.2 mg/L.
