Embodiment 1

[0009] The oxidation ditch system consists of a water storage tank 1, a peristaltic pump 2, a biological selector 3, an oxidation ditch 5 and a secondary sedimentation tank 6 which are connected in sequence. A surface aerator 6 is provided in the oxidation ditch 5 .

[0010] The biological selector 3 is made of PVC plastic plate, with a total effective volume of 23.33 L, divided into 6 grids, each grid is 3.89 L; the main reactor is made of stainless steel, the effective volume of the oxidation ditch 5 is 240 L, and the effective volume of the secondary sedimentation tank 6 is The capacity is 100 L. The bioselector 3 is stirred by a small submersible pump, and the reaction conditions are varied between anoxic and anaerobic. Oxidation ditch 5 uses surface aerator 4 for aeration, and aerator 4 realizes the process of aeration and pushing flow in the ditch (the aerator at the water inlet mainly plays the role of aeration, and the last two aerators mainly play the role of pushing...

Abstract

The invention relates to a wastewater treatment device, and discloses an oxidation ditch system comprising successively connected a water reservoir, a peristaltic pump, a biological selector, an oxidation ditch and a secondary sedimentation tank. The oxidation ditch system keeps a good sludge sedimentation performance, and can effectively inhibit the occurrence and development of sludge bulking.

Description

technical field [0001] The invention relates to a waste water treatment device. Background technique [0002] Oxidation ditch is widely used in sewage treatment, but the problem of sludge bulking in oxidation ditch has also attracted people's attention. In 1973, Chudoba was the first to clearly propose the use of biological selectors to control sludge bulking. Later, scholars at home and abroad applied the biological selector to the oxidation ditch to control sludge bulking, and conducted a lot of research on the oxidation ditch in the improved oxidation ditch system with the pre-biological selector, but the operation of the biological selector in the system parameters are less studied. After setting the bioselector, the substrate distribution and biophase composition in the oxidation ditch changed. Therefore, the influence of the biological selector on the oxidation ditch system not only involves the sludge settling performance, but also has a certain influence on ...
