Hydrolytic acidification reaction tank for sewage treatment

Abstract

The invention discloses a hydrolytic acidification reaction tank for sewage treatment, which structurally comprises a feeding pipe, a reaction cover, a bracket frame, a reaction device and a centralized acidification part, the feeding pipe is inserted in the middle of the reaction cover and is communicated with the interior of the reaction device, the reaction device is sleeved with the bracket frame, and the bottom of the reaction device is fixedly connected with the centralized acidification part; shaking deformation is carried out in the fixed range of gathering bolts between limiting parts, so that a conversion device fluctuates intermittently, a sludge accumulation surface is prevented from being expanded, extruded and overlapped, the inclined surface of the conversion device surfaceis gradually changed into a plane shape, and when sludge with different sizes falls onto the inclined surface of the conversion device, a supporting device at the bottom of the conversion device can make the conversion device fluctuate up and down through high-speed rotation under the bolt connection matching effect of attaching blocks, the effective energy absorption and buffering effect is achieved, pits with different depths cannot be formed in the surface of the inclined face, and equipment internal functional components are not damaged.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a hydrolysis acidification reaction pool for sewage treatment. Background technique [0002] The hydrolysis treatment method is a method between aerobic and anaerobic treatment methods, and the combination with other processes can reduce the treatment cost and improve the treatment efficiency. The existing hydrolysis acidification reaction tank has a simple structure, and the sludge is prone to concentrated accumulation, thus The decomposition efficiency is reduced, and a diversion table with a conical structure is usually used to solve this problem, but since the sludge is affected by the height between the feed inlet and the diversion table, the weight of the sludge falling on the diversion table is impossible Similarly, the sludge hits the inclined surface of the diverter table at a high flow rate, and forms a hedge against the inclined surface, resulting in the inability of th...

Problems solved by technology

[0003] In view of the above, because the sludge is affected by the height between the feed inlet and the diversion platform, the weight of the sludge falling on the diversion platform cannot be the same. The hedging is formed on the inclined surface, so that the inclined surface cannot effectively absorb energy and buffer when it is hit, and the surface of the inclined surface is smashed into pits of different depths, and the sludge falling on the inclined surface will be everywhere in a unit time. Random splashing aggravates the abrasion of the sludge on the surface of the diversion table, causing the sludge accumulation surface to expand, squeeze and overlap, and make its inclined surface gradually become flat, resulting in the loss of the diversion function of the diversion table and seriously affecting the hydrolysis. Acidification reaction progress problem, the present invention provides a hydrolysis acidification reaction pool for sewage treatment
