Embodiment 1

[0024] Example 1: Combining figure 1 and figure 2 Illustrate the reactor of the present invention that can improve the biodegradability of refractory organic sewage. The reactor 10 of this embodiment is a box in the shape of a cuboid. The top of the left side wall of the reactor 10 is provided with a water inlet 11. The top of the wall is provided with a water outlet 12, and three baffle assemblies 20 are arranged side by side and spaced apart in the housing of the reactor 10, and the arrangement direction of the three baffle assemblies 20 is consistent with the water flow direction in the reactor 10 ( figure 1 The direction indicated by the arrow in the dotted line is the sewage water flow direction); each baffle assembly 20 includes vertical and spaced guide baffles 21 and baffles 22, and the guide baffles 21 and baffles 22 All are corrugated plates; in each baffle assembly 20, the top of the diversion baffle 21 near the water inlet 11 is connected to the top of the reacto...

Embodiment 2

[0032] Embodiment 2: Combination figure 1 Illustrate a kind of method that can improve the biodegradability of refractory organic sewage of the present invention, concrete steps are as follows:

[0033] Using the reactor 10 described in Example 1, the bottom of the reactor 10 is filled with an appropriate amount of volcanic rock, and the upper part of the volcanic rock is provided with an elastic three-dimensional filler. The sludge is obtained from the anaerobic hydrolysis tank of a sewage treatment plant for film-hanging domestication and sent into the reaction The reactor 10 uses a peristaltic pump to draw the pretreated sewage into the reactor 10 through the water inlet, and the sewage passes through three diversion chambers a and three anaerobic hydrolysis reaction chambers formed by three baffle assemblies 20 in sequence, so that The sewage and the elastic three-dimensional filler are fully stirred and contacted and reacted. The purified water is discharged from the reac...

Abstract

The invention provides a reactor and a method capable of improving the biodegradability of difficult-to-degrade organic sewage and relates to the technical field of sewage treatment, aiming at solvingproblems of an existing anaerobic hydrolysis acidification reactor that the effect is not stable, anaerobic sludge loss is easy to cause and the like. A shell body of the reactor is internally provided with at least three baffle plate assemblies in parallel and at intervals; each baffle plate assembly comprises a flow guide baffle plate and a baffling baffle plate, which are vertically arranged at an interval, and the flow guide baffle plate and the baffling baffle plate are wave-shaped plates; the top ends of the flow guide baffle plates are connected to the top part of the reactor and the bottom ends of the flow guide baffle plates and the bottom part of the reactor are arranged at intervals; the bottom ends of the baffling baffle plates are connected to the bottom part of the reactor and the top ends of the baffling baffle plates and the top part of the reactor are arranged at intervals. The method comprises the following steps: paving volcanic rock at the bottom part of the reactor and filling elastic three-dimensional filler; introducing the sewage into the reactor through a water inlet hole and enabling the sewage to sequentially pass through a flow guide chamber composed ofthe at least three baffle plate assemblies and an anaerobic hydrolysis reaction chamber, so that the sewage and the elastic three-dimensional filler are sufficiently stirred and are in contact to react; a purified water body is discharged out from the reactor through a water outlet.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a reactor and a method capable of improving the biodegradability of refractory organic sewage. Background technique [0002] The diversity of textile printing and dyeing products determines that their production processes are very different. There are many kinds of raw materials and auxiliary materials, and the water quality of printing and dyeing wastewater is complex and changeable. In particular, artificial synthetic fibers are used as raw materials in the textile printing and dyeing production process and are blended with various natural fibers. Products, so that the quality of printing and dyeing wastewater is also constantly changing. For products with a high content of synthetic fibers, the wastewater discharged during the production process contains polymer dyes, additives, and PVA and other refractory organic substances, and the biodegradability of the wastewate...
