SU1375571A1 - Oxidizing channel - Google Patents

Abstract

The invention relates to devices for the treatment of small amounts of wastewater, namely, oxidation channels, aeration tanks, aerated ponds, working in circulation mode through the channel, and allows to intensify the cleaning process, reduce energy costs, ensure reliability, efficiency, ease of operation. The oxidation channel comprises a straight-line section 1, divided by a longitudinal partition 2 into communicating channels 8 and 9, input 6 and output 7 of treated water, an aeration system. The main air duct 3 is located above the longitudinal partition, aerators 4 are located around the longitudinal partition and in the corners of the channel at the bottom. In the lower part, nozzles 5 are evenly spaced 0.2-0.5 from the bottom of the housing. Aerators and nozzles are connected at right angles to the main duct. A pneumatic aeration system is introduced throughout the channel volume. 1 з, п, ф-л, 4 Il. e

The invention relates to devices for the treatment of small amounts of wastewater, namely to oxidation channels, aeration tanks, aerated ponds operating in the circulation mode of the waste water through the channel.

The purpose of the invention is to intensify the cleaning process, reducing energy consumption, ensuring reliability, simplification and efficiency.

Figure 1 presents the proposed oxidative channel, top view; in Fig. 2 is a section aa in Fig. 1; on fig.Z - tap with nozzles; figure 4 - section bb in fig.Z.

The oxidation channel has a rectangular case-1, a longitudinal partition 2, a main air line 3, aerators 4, guide nozzles 5 located, like the aerators 4, perpendicular to the main air line 3, nodes 6 and 7 of the water inlet and outlet. The nozzles 5 are located at a distance of 0.2-0.5 from the bottom of the housing equal to 0.2-0.5 of the working depth. The oxidation channel is divided by a longitudinal partition 2 into two interconnected channels 8 and 9.

The channel works as follows.

Sewage enters the housing through node 6. Aerators 4 create rotational movement of water in channels 8 and 9. Progressive movement of water is achieved through nozzles 5. Water is removed through the pipeline of node 7. Active sludge returns by an airlift (not shown),

fed from the main air duct.

The use of the oxidation channel provides a highly efficient cleaning during year-round operation, reduces energy consumption, eliminates the use of activated sludge pumps, mechanical aerators, drainage pumps, the installation is generally simplified, it becomes more economical.
