Embodiment Construction

[0017] See attached picture. figure 1 Among them, A is blue charcoal wastewater; B is residual ozone; C is residual sludge; D is sludge return; E is mixed liquid return; F is effluent or reuse.

[0018] The blue charcoal wastewater in this project comes from the wastewater of a blue charcoal production plant after ammonia distillation, dephenolization, and deoiling. It is composed of phenolic wastewater and oily wastewater (at a 4:6 inflow). Water quality indicators As shown in Table 1, press figure 1 The design of the process flow is 1m 3 / h device is running. Among them, the first aerobic pool is divided into three sections, 31, 32, and 33, which together form an S-shaped corridor, in which water flows in the direction of the arrow. There are three return ports 11, 13, and 12 on the corridor. As can be seen from the figure, they are respectively located at 1 / 3, 2 / 3 and the end of the process.

[0019]

[0020] The overall processing procedure of this embodiment is as follows.

Abstract

The invention discloses a biochemical treatment method of industrial wastewater and an aerobic tank. The biochemical treatment method of industrial wastewater comprises a multifunctional denitrification tank and an aerobic tank. An HSBEMBM environmental management microbial preparation is added to both the multifunctional denitrification tank and the aerobic tank; mixed liquid in the aerobic tank partially returns to the multifunctional denitrification tank, the aerobic tank is provided with a plurality of return openings in the flow direction of the aerobic tank and the return openings are all communicated with return pipelines, wherein the return opening at the tail end is normally open. The aerobic tank adopts an S-shaped corridor so that water flows in the corridor. The aerobic tank is mainly responsible for decarburization and partial nitrification. The plurality of return openings are arranged in the corridor in the aerobic tank so that the return positions and return quantity are adjusted according to the inlet water quality and the operation condition of the whole system. Due to arrangement of the return openings, the different return positions and return quantity can be adjusted in time during the implementation process; therefore, high-efficiency denitrification is realized and COD is removed; moreover, the denitrification efficiency and the buffer resistance of the system are improved.

Description

Technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a method for biochemical treatment of industrial wastewater, and an aerobic tank used in the biochemical treatment process. Background technique [0002] The use of biochemical technology to treat wastewater, especially for the treatment of total nitrogen removal, is already a fairly mature process route. The applicant also did a lot of research on this and applied for invention patents such as 200710164865 and 201210242756. The common point of all these process routes is the pretreatment unit, the biochemical treatment unit and the advanced treatment unit. The core is the biochemical treatment unit, through the combination of different oxygen consumption conditions and various parameter control to achieve different treatment effects . In the biochemical treatment unit, certain microorganisms need to be added, and during the reaction process, it is necessary ...
