Embodiment Construction

[0042] See figure 1 , figure 2 , image 3 .

[0043]Annular anoxic / aerobic segmented water inlet, falling water, oxygenation, biological contact oxidation integrated equipment is composed of two concentric cylinders, the central area of ​​the inner cylinder constitutes a vertical flow sedimentation chamber VII, and the side walls of the two concentric cylinders inside and outside The area between and the bottom of the pool is an annular segmented water inlet, water drop, oxygenation, contact oxidation integrated reaction area, and the vertical partitions on both sides are consolidated with the side walls of the inner and outer cylinders to sequentially divide the area into end-to-end rings. The first anoxic zone I, the first aerobic reaction zone II, the second anoxic zone III, the second aerobic zone IV, the third anoxic zone V and the third aerobic zone VI; The partition between the first anoxic zone and the first aerobic reaction zone, the partition between the second a...

Abstract

The invention belongs to the field of treating dispersed point source wastewater through utilization of biotechnology of an environment engineering method and relates to anoxic / aerobic step water feed and drop oxygenation bio-contact oxidation integrated equipment and an operation method. The equipment consists of two concentric cylinders; an inner cylinder is a vertical flow type settling chamber; a clapboard is arranged between the outer cylinder and the inner cylinder; an annular region is divided into three anoxic regions and three aerobic reaction regions; each reaction region is filled with a spherical filler; and six reaction regions alternately form anoxic / aerobic units through the control of dissolved oxygen. Firstly, wastewater enters the anoxic regions; height difference is kept between the liquid level of the each anoxic region and the next aerobic reaction region; and outlet water of the anoxic region enters the aerobic reaction region through perforation of drop water ofa water distribution groove. The aerobic reaction region and the next anoxic reaction region are separated through the clapboard; gap is reserved between the bottom of the clapboard and the bottom ofa pool; and the last aerobic reaction region and the vertical flow type settling chamber are connected through a pipeline. The equipment is utilized to remove total suspended solid, organic pollutant, total nitrogen and the like of the wastewater.

Description

technical field [0001] The invention belongs to the field of using biological technology in environmental engineering methods to treat scattered point source sewage, and in particular relates to an anoxic / aerobic segmented water inflow, water drop, oxygenation and biological contact oxidation integrated equipment and method suitable for the treatment of scattered point source sewage. Background technique [0002] The level of rural modernization continues to improve, and the discharge of domestic sewage is increasing day by day. Many rural areas are either adjacent to lakes that serve as urban water sources, or are the areas where important rivers flow. The arbitrary discharge of rural sewage not only leads to the decline of water quality in water sources, but also seriously threatens drinking water resources that are not rich in the first place; , The surface runoff formed by rainwater carries a large amount of pollutants into the water body, which is likely to cause eutrop...
