Homogeneous pool esterification water treatment system and treatment method

Abstract

The invention discloses a homogeneous pool esterification water treatment system. The system comprises a homogeneous pool, a storage barrel, an upper self-suction pipe, a lower equilibrium inhalation pipe, a centrifugal pump, a control valve and a circulating pipeline. The height of the reserves of the storage barrel is less than that of the homogeneous pool; one pipe orifice of the upper self-suction pipe inserts into the bottom of the homogeneous pool, and the other pipe orifice is connected to the storage barrel through the lower equilibrium inhalation pipe; one end of the circulating pipe communicates with the storage barrel, and the other end of the circulating pipe communicates with the homogeneous pool; the centrifugal pump and the control valve are arranged on the circulating pipeline; and the storage barrel is provided with a water inlet pipe. A treatment method of the system uses the homogeneous pool to reduce COD index of the esterification water, and circulation operation is conducted on the esterification water in the homogeneous process. The invention can effectively improve the outlet water quality of homogeneous esterification water, reduce COD index of the outlet esterification water, and enable the precipitated sludge to conduct self-circulation timely and effectively, and reduce the loss of sludge.

Description

technical field [0001] The invention relates to a water treatment system and a treatment method thereof, in particular to a homogeneous pool esterification water treatment system and a treatment method thereof. Background technique [0002] The existing homogeneous pool esterification water treatment system includes a homogeneous pool, and the sludge settling pool of the homogeneous pool treatment device is a rectangular, flat-bottomed pool. After long-term use and observation, it is found that after the sludge settles, the sewage discharge effect is not very satisfactory. Effectively circulate the sludge in the four-sided pool, and the sludge in the effluent is serious, which affects the effect of the anaerobic esterification water, and the sedimentation of the sludge during the sludge treatment process is also very uneven. The amount of water is unstable, the effluent is turbid, the effect of acidification in the homogeneous pool is basically invalid, the COD value in the ...

[0002] The existing homogeneous pool esterification water treatment system includes a homogeneous pool, and the sludge settling pool of the homogeneous pool treatment device is a rectangular, flat-bottomed pool. After long-term use and observation, it is found that after the sludge settles, the sewage discharge effect is not very satisfactory. Effectively circulate the sludge in the four-sided pool, and the sludge in the effluent is serious, which affects the effect of the anaerobic esterification water, and the sedimentation of the sludge during the sludge treatment process is also very uneven. The amount of water is unstable, the effluent is turbid, the effect of acidification in the homogeneous pool is basically invalid, the COD value in the esterification water has not been effectively reduced, and the sludge at the bottom of the pool is difficult to return, and some sludge accumulates in multiple dead corners of the pool. It cannot be discharged through the screw pump circulation in time, and the long-term production time will affect the sedimentation of the sludge, which will increase the COD value of the effluent, and the production stability and stability of the sewage treatment process will decrease. Therefore, it is necessary to improve
