Embodiment 1

[0035] See figure 1 , figure 2 and image 3 .

[0036] The integrated oxidation ditch equipment of lateral sedimentation stereo circulation includes stereo circulation oxidation ditch I, left lateral sedimentation solid-liquid separator II and right lateral sedimentation solid-liquid separator III.

[0037] The lateral sedimentation solid-liquid separator is respectively located on the left side and the right side of the three-dimensional circulation oxidation ditch, and the left lateral precipitation solid-liquid separator and the left side wall of the three-dimensional circulation oxidation ditch which is an inner hollow box A left wall 1 is shared, and the right wall 2 of the three-dimensional circulation oxidation ditch shares the right wall 2 with the right lateral sedimentation solid-liquid separator.

[0038] Inside the three-dimensional circulation oxidation ditch which is an inner hollow box, there is a transverse partition 7 to divide the three-dimensional circul...

Abstract

The invention belongs to the field of treating sewage by the biotechnology, relating to a side direction precipitation vertical circulation integrated oxidation ditch and an operation method thereof. The invention comprises a vertical circulation oxidation ditch and two side direction precipitation solid-liquid separators which are arranged at the left side and the right side of the vertical circulation oxidation ditch. The left side direction precipitation solid-liquid separator uses one side wall which is the left side wall of the vertical circulation oxidation ditch of an inner empty case.The vertical circulation oxidation ditch shares the right side wall with the right side direction precipitation solid-liquid separator. The vertical circulation oxidation ditch is divided into an upper ditch and a lower ditch by a diaphragm plate in the interior of the case, wherein, the two sides of the diaphragm plate are respectively concreted with the side walls which the left side direction precipitation solid-liquid separator and the light side direction precipitation solid-liquid separator share with the vertical circulation oxidation ditch while the other two sides of the diaphragm plate leaves an air gap with the other two inner walls of the case; and two side walls which the upper part and the lower part of the diaphragm plate share are both opened with a slit so that the left side direction precipitation solid-liquid separator and the right side direction precipitation solid-liquid separator are communicated with the upper ditch and the lower ditch of the vertical circulation oxidation ditch. The invention is used for removing organic contaminant, total azote and total suspended solid and the like in water.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment by using biological technology, and in particular relates to a lateral precipitation three-dimensional circulation integrated oxidation ditch suitable for domestic sewage or industrial wastewater treatment and an operation method thereof. Background technique [0002] Oxidation ditch is a simple sewage treatment technology composed of continuous ring reaction tanks, which is a variant of activated sludge process. In the 1950s, it was first successfully developed by the Netherlands Sanitary Engineering Research Institute. Thanks to the efforts of scientists and environmental engineers from various countries for nearly 50 years, great progress has been made in oxidation ditch technology. Studies have shown that the oxidation ditch process has the characteristics of high removal rate of organic pollutants, simultaneous nitrogen and phosphorus removal, stable operation effect, convenient man...
