Abstract

The utility model relates to a multi-pole activated sludge waste water treatment device with a function of counterflow aeration, which belongs to the technical field of water treatment. An upper opening of each reactor in which a baffle plate is arranged to separate each reactor into four independent parts is provided with a cover body; an air blocking plate and a spout hole are arranged at the position of each baffle plate near to each cover body. An air guide pipe in a reverse L shape is arranged between the reactors of adjacent levels; one end of the air guiding pipe is connected with an upper cover of the reactor of next level, and the other end of which the end opening is provided with an aeration pipe travels through the corresponding cover body of the reactor of last level to extend to the bottom of the cover body. The utility model has the characteristics of high oxygen transfer efficiency, few harmful substances in exhaust air, no mechanical agitating facilities in the reactors and simple management and operation.

Description

The multipole active sludge wastewater treatment equipment of adverse current aeration

Technical field:

The utility model belongs to water-treatment technology field, relates to a kind of improvement of water treatment device.

Background technology:

Existing active sludge wastewater treatment equipment mainly is made of reactor, active sludge, reflux sludge tube, water inlet pipe, inlet pipe, aeration tube, rising pipe, reactor is a rectangular box, its top is an open type, the mixed solution upper surface directly communicates bubble pathway length for straight up with atmosphere, stroke is short, oxygen transfer efficiency is low, the working cost height.

Summary of the invention:

Technical problem to be solved in the utility model is to disclose a kind of oxygen transformation efficiency height, the wastewater treatment equipment that processing costs is low.

The scheme of the utility model technical solution problem is in upper shed place of reactor lid to be housed, three baffle plates are housed in the reactor, the upper end of baffle plate connects lid, lower end ligation device bottom, reactor is divided into A reactor, second reactor, three reactor, four independent sectors of fourth-order reaction device, near the lid place U-shaped anti-aeration plate and n shape anti-aeration plate are housed at baffle plate, the opening correspondence of U-shaped anti-aeration plate and n shape anti-aeration plate, n shape anti-aeration plate is contained in the U-shaped anti-aeration plate, have overflow weir on the baffle plate in the n shape anti-aeration plate, reflux sludge tube, water inlet pipe vertically is contained on the lid of A reactor correspondence, inlet pipe vertically is contained on the corresponding lid of fourth-order reaction device, on the lid of A reactor correspondence, vapor pipe is housed, L shaped airway is housed down between the reactor of adjacent level, airway one end is connected next stage reactor loam cake place, the other end passes the lid of upper level reactor correspondence, and extend into its bottom, in the port aeration tube is housed.Owing to installed lid additional, reactor forms closed, and installed baffle plate additional, make reactor be divided into four independent parts, the structure of U-shaped anti-aeration plate and n shape anti-aeration plate and overflow weir makes liquid can pass through the upper level reactor stream to the next stage reactor, gas can not flow, and can only flow by airway, last reactor liquid level pressure is normal pressure, remaining reaction device internal pressure from after forward pressure increase gradually because step by step transfer, concentration of oxygen reduces gradually in the gas, the concentration of oxygen also reduces gradually in the mixed solution, by the control of air demand, can realize anoxic, the aerobic biochemical characteristic.

The utlity model has the oxygen transfer efficiency height, objectionable impurities is few in the waste gas, does not have machinery in the reactor and stirs facility, operational management characteristic of simple.
