Problems solved by technology

[0003] The existing anoxic pool has certain disadvantages in the process of use. The investment of the submersible mixer increases the investment of sewage treatment, and later maintenance is required, which costs a lot. The nitrifying bacteria are fully exposed, the denitrification effect is not good, and the short flow of wastewater cannot be prevented, the anoxic reaction is relatively slow, and the denitrifying bacteria micelles are easy to lose

Embodiment Construction

[0033]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] Such as Figure 1-5 As shown, an improved up-flow composite anoxic pool includes an anoxic pool 1 and a reaction pool 2 arranged outside thereof, an aerobic pool 3 is installed on one side of the anoxic pool 1, and the anoxic pool 1 and The aerobic pool 3 is located side by side in the reaction pool 2. The anoxic pool 1 is provided with a water outlet 4 near the upper end of the side wall of the aerobic pool 3. The left side of the aerobic pool 3 is provided with a regulatin...

Abstract

The invention discloses an improved up-flow composite anoxic tank. The improved up-flow composite anoxic tank comprises an anoxic tank and a reaction tank arranged outside the anoxic tank, anaerobic tank is mounted at one side of the anoxic tank, the anoxic tank is juxtaposed with the aerobic tank in the reaction tank, a water outlet is arranged in a position, close to the aerobic tank, of the upper end of one sidewall of the anoxic tank, and a regulating tank is arranged at the left side of the aerobic tank. A Venturi tube is arranged to replace a submersible mixer in a traditional anoxic tank to achieve the stirring function, so the investment, operation and maintenance of the submersible mixer in the traditional anoxic tank are saved, and the cost is greatly reduced; a mixed solution can well contact with denitrifying bacteria in the up-flow process to make the denitrifying bacteria play a role in denitrification in order to achieve nitrogen removal; short-flowing of wastewater canbe effectively prevented to ensure the high efficiency of an anoxic reaction; a nitrifying solution can be recovered and reused, so resources are saved; and denitrifying bacteria micelles can be retained to prevent the loss of denitrifying bacteria micelles.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an anoxic pool, in particular to an improved upflow composite anoxic pool. Background technique [0002] Anoxic pool refers to a reaction pool without dissolved oxygen but with nitrate. In the denitrification process, it mainly plays the role of denitrification to remove nitrate nitrogen, and at the same time removes part of BOD, and also has the effect of hydrolysis reaction to improve biodegradability. The traditional anoxic tank is used in conjunction with the aerobic tank. A submersible mixer is installed at the bottom of the anoxic tank to perform the stirring function, so that the bottom denitrifying bacteria micelles and the mixed solution are fully mixed. The investment of the submersible mixer increases the investment in sewage treatment, and It needs to be maintained in the later stage, which greatly increases the investment cost. Now it is urgent t...
