The specific use method of the water body treatment system comprises the following steps:
(1) the submersible pump 100 and the first electromagnetic valve 171 are opened, the river water body enters the sedimentation tank 110 from the sedimentation tank water inlet 114, the sludge with larger particles enters the bottom of the sedimentation tank 110 under the action of the inclined pipe 111, the water and the organic and inorganic substances dissolved in the water are discharged from the sedimentation tank water outlet 115 through the overflow port 112 and enter the biochemical membrane tank 120 from the biochemical membrane tank water inlet 123.
(2) By continuous aeration of the aeration pipe 122 and the membrane module 121 in the biochemical membrane tank 120, organic matters in the water are degraded and removed by activated sludge formed by microorganisms.
(3) The water body with the degraded organic matters enters the first denitrification tank 130 from the biochemical membrane tank water outlet 124 through the first denitrification tank water inlet 132, the pyrite filter material 131 in the first denitrification tank 130 contains rich sulfur autotrophic denitrifying bacteria, low-valent sulfur is used as an electron donor, nitrate in the water body is used as an electron acceptor, denitrification is carried out, and the reaction equation of the total reaction is as follows: 18NO3 -+10FeS+16H2O→10Fe(OH)3+9N2+10SO4 2-+2H+Simultaneously, Fe (OH) produced3The colloid can remove phosphorus with phosphate precipitation. Part of the total nitrogen and most of the total phosphorus in the wastewater can be effectively reduced by the first denitrification tank 130. Therefore, in view of the low solubility of the pyrite filter 131, when the total nitrogen concentration in the water to be treated is low, for example, not greater than 15mg/L, the twelfth electromagnetic valve 174b is closed, the water cannot enter the second denitrification tank 140 after being treated by the first denitrification tank 130, and the eleventh electromagnetic valve 174a is opened to enable the water to directly enter the disinfection tank 150 for disinfection; when the total nitrogen concentration in the water body to be treated is high, the water body enters the second denitrification tank 140 through the water inlet 142 of the second denitrification tank after being treated by the first denitrification tank 130 to continue to react. The adjustment mode is used for dealing with the larger water quality fluctuation of the riverway or other water bodies, and the number and the treatment cost of the reactors are reduced while the stable treatment is carried out.
(4) The sulfur filter material 141 in the second denitrification tank 140 also contains rich sulfur autotrophic denitrifying bacteria, and the sulfur has the following general reaction in the water body contact process: 55S +50NO3 -+38H2O+20CO2+4NH4 +→4C5H7O2N+25N2+55SO4 2-+64H+. The residual total nitrogen in the water body can be further degraded through the reaction. In the denitrification process in the first denitrification tank 130 and the second denitrification tank 140, the system can operate efficiently without adding carbon sources under the condition of low carbon-nitrogen ratio.
