Description

Biochemical pond for sewage treatment Technical Field The application relates to the technical field of sewage treatment equipment, in particular to a biochemical tank for sewage treatment. Background The treatment of domestic sewage generally comprises a dead-spot treatment, a secondary treatment and a tertiary treatment, wherein the primary treatment is to remove solid impurities and suspended pollutants in the sewage in a filtering and precipitation mode, the secondary treatment is to decompose organic pollutants in the sewage by utilizing microorganisms, and the tertiary treatment is to denitrify and dephosphorize the sewage by utilizing chemical reaction and remove refractory inorganic salts in the sewage. When secondary treatment is carried out on domestic sewage, the sewage is usually conveyed into a biochemical tank, a solution containing biological sludge is preset in the biochemical tank, after the sewage enters the biochemical tank, microorganisms contained in the biological sludge decompose organic pollutants in the sewage, after the sewage stays in the biochemical tank for a certain time, the organic pollutants contained in the sewage are decomposed, the sewage is discharged out of the biochemical tank and enters a subsequent sewage treatment station, and the biochemical tank can continuously treat the sewage which enters subsequently. In the secondary treatment process of the sewage, when the sewage is discharged from the biochemical tank, microorganisms in the biochemical tank are inevitably carried outside the biochemical tank, so that the microorganisms in the biochemical tank are lost, and along with the progress of sewage treatment, the sewage treatment efficiency of the biochemical tank is gradually reduced. Disclosure of utility model The application provides a biochemical tank for sewage treatment in order to improve sewage treatment efficiency of the biochemical tank. The application provides a biochemical tank for sewage treatment, which adopts the following technical scheme: The biochemical tank for sewage treatment comprises a tank body, a mounting frame and a feeding box, wherein the tank body is of a top opening structure, a water inlet pipe and a water outlet pipe are communicated with the tank body, a water pump is mounted on the water outlet pipe, the mounting frame is arranged at the top of the tank body, the feeding box is arranged on the mounting frame, the feeding box is of a top opening structure, a feeding pipe is communicated with the bottom of the feeding box, an adjusting component is arranged on the feeding box and is used for adjusting the communicating state of the feeding pipe, a first driving component and a second driving component are arranged on the tank body, the first driving component is used for driving the feeding box to move along the length direction of the tank body, and the second driving component is used for driving the feeding box to move along the width direction of the tank body. Through adopting above-mentioned technical scheme, when carrying out the secondary treatment to sewage, carry the cell body inside with sewage through the inlet tube, the solution that contains biological mud is equipped with in advance in the cell body inside, after sewage gets into the cell body, the microorganism that contains in the biological mud decomposes the organic pollutant in the sewage, after the sewage stops certain time in biochemical pond, wherein contained organic pollutant is decomposed and finishes, sewage passes through the drain pipe discharge cell body under the effect of water pump, get into follow-up sewage treatment station, the secondary treatment of sewage finishes. When carrying out the secondary treatment to sewage, operating personnel adds quantitative sludge cake that is rich in microorganism to the throwing incasement earlier, then utilize first drive assembly and second drive assembly, make the throwing incasement remove along the width direction of cell body when following the length direction of cell body, in this process, utilize adjusting part to make the throwing pipe be in the intercommunication state, the sludge cake in the throwing incasement drops to the inside everywhere of cell body through throwing pipe under self gravity effect, for lasting supplementary microorganism in the cell body, avoid carrying the condition that microorganism content reduces in the cell body that the microorganism leads to when discharging because of sewage, thereby guarantee the treatment effeciency to sewage. And the sludge cake can evenly drop to each position of the tank body, so that the sludge cake can be fully dissolved in each position of the tank body, and the treatment efficiency of sewage in the tank body is further improved. The automatic feeding device comprises a feeding pipe, a feeding assembly, an adjusting assembly, a feeding assembly and an adjusting assembly, wherein the feeding pipe is arranged in the feeding pipe, the feeding assemb
