Abstract
The utility model relates to a sewage hydrolysis acidification purified groove, comprising a groove body, and an inlet (1) and an outlet (8) which are arranged on the two sides of the groove body, wherein the water inlet end of the groove body is provided with a water distribution system; the surface layer of the water level surface on the upper part of the groove body is provided with a water collecting system which is communicated with the outlet (8); the position of an anaerobic sludge bed formed in the middle of the groove body is equipped with a sludge discharging system; and the interior of the groove body is divided into a plurality of absolute reacting chambers along with the length direction by a clapboard (5). The purified groove designs the unique water distribution, water collecting and sludge discharging systems and becomes an anaerobic upflow sludge bed device which mainly has hydrolysis acid-producing bacterium. Since the anaerobic hydrolysis sludge bed integrates biological degradation, physical deposition and adsorption together, under the condition of being close to the retention time of the primary deposition pool, the removal ratio of removing the colloid organic matter and the soluble macromolecular organic matter is notably higher than that of the traditional primary deposition pool under the situation that the efficiency of removing the settleable organic matter is constant. Simultaneously, the hydrolysis acid-producing bacterium translates the non-degradable macromolecular organic matter in the sewage into micro-molecular organic matter, thereby advancing the biodegradability of the sewage and causing the subsequent aerobic technology to enhance the removal ratio of BOD and reduce the energy consumption.
Description
(1) technical field
The utility model belongs to a kind of sewage primary reinforcement treatment and purification groove of miniaturization, specifically a kind of sewage hydrolyzing acidifying purification tank, it can be used for the primary reinforcement of sewage separately handles, and also can be used in combination the pretreatment unit as second-stage treatment with other technology.
(2) technical background
Traditional one-level treatment process mostly adopts the physical sedimentation principle, and its purification tank is normally by cell body and place the water inlet pipe of cell body both sides and water shoot to form.It can remove in the sewage macrobead by natural subsidence can sink organism, but then powerless to the colloidal organic matter and the dissolved organic matter that can not sink.
(3) summary of the invention
The purpose of this utility model is to provide a kind of sewage hydrolyzing acidifying purification tank, and it can effectively removed the organic while of settleability in the sewage, significantly improves to sink colloidal organic matter and the organic clearance of soluble large molecule in the sewage.The entrance and exit that this sewage hydrolyzing acidifying purification tank comprises cell body and places the cell body both sides, the water intake end of cell body is provided with water distribution system, water surface top layer, cell body top is provided with water gathering system and is communicated with outlet, the anaerobic mud bed position based on the hydrolysis acid-producing bacteria that the cell body middle part forms is provided with sludge drainage system, and the cell body inner route clapboard is separated into some independently reaction chambers along its length.This sewage hydrolyzing acidifying purification tank is on the basis of traditional preliminary sedimentation tank, unique water distribution system, water gathering system and sludge drainage system have been designed, make it to become anaerobism upflow sludge blanket device based on the hydrolysis acid-producing bacteria, because the biological degradation of anaerobic hydrolysis Sludge Bed collection, physics sedimentation and be adsorbed as one, under the situation close with the preliminary sedimentation tank residence time, removing under the constant situation of settleability organic matter efficiency, it is significantly higher than preliminary sedimentation tank to colloidal organic matter and the organic clearance of soluble large molecule.Simultaneously, the hydrolysis acid-producing bacteria transforms small organic molecule with the larger molecular organics of difficult degradation in the sewage, has improved the biodegradable of sewage, and follow-up aerobic process is cut down the consumption of energy when improving the BOD clearance.
