Water-channel water distribution-type water-distributing system for hydrolysis-acidification pool in industrial waste water treatment

Abstract

The invention relates to a water-channel water distribution-type water-distributing system for a hydrolysis-acidification pool in industrial waste water treatment, which comprises several water-distributing pipes, and is characterized in that one or more than one water-distributing channel with a movable cover plate is disposed at a top of a hydrolysis-acidification pool; the two ends of the water-distributing channel are fixedly connected to two facing pool walls and are perpendicular to the pool walls; a water-inlet opening is disposed on an end wall of the water-distributing channel; an escape pipe is disposed at the bottom; multiple vertical and horizontal rows of vertical water-distributing pipes are disposed along the channel at the channel bottom across the full length of the water-distributing channel; the upper end ports of the pipes are higher than the channel bottom of the water-distributing channel, and the lower end ports extend to the outside of the water-distributing channel; the upper end ports of the water-distributing pipes are higher than the upper edge of the water inlet opening, and is provided with a V-shaped weir port; the upper end ports of the water-distributing pipes are detachably connected to the lower end ports of the water-distributing pipes; the lower end parts of the water-distributing pipes are perpendicular to the bottom surface of the hydrolysis-acidification pool, and are fixedly and uniformly arranged with a distance maintained between the lower end ports and the pool bottom surface; a cone roof reflection bench is disposed between the lower end ports of the water-distributing pipes and the pool bottom surface. The advantages of the invention are that the invention realizes uniform water distribution, increases the biodegradability of industrial waste water, reduces equipment cost, and is convenient for installation and maintenance.

Description

technical field [0001] The invention relates to a water distribution facility for industrial wastewater treatment, in particular to a water distribution type water distribution system for an industrial wastewater treatment hydrolysis acidification pool. Background technique [0002] In the process of using hydrolytic acidification tank plus improved oxidation ditch for industrial wastewater treatment, the hydrolytic acidification process can convert macromolecular substances in industrial wastewater into small molecular substances, and convert ring structures into chain structures, so that the BOD / The COD ratio is further improved, which improves the biodegradability of industrial wastewater and creates a good environment for subsequent disinfection treatment. One of the important conditions for the good operation of the hydrolytic acidification reactor is to ensure sufficient contact between the sludge and the industrial wastewater. The uniform distribution of the industri...

AI Technical Summary

Problems solved by technology

[0003] The main defects of the existing water distribution system are: (1) the water distribution tanks 3e are sequentially supplied with the pipeline structure in series. Due to the head loss in the water inlet pipe 2e, such a water intake structure will inevitably cause the connection between the front end of the pipeline and the end of the pipeline. The water distribution tanks have different water volumes and different water quality conditions

(2) The existing water distribution tank 3e is an integral structure, which is purchased as a complete set. The equipment itself has very strict requirements on the structure, and the equipment has a large dead weight. It must be fixed on the top of the hydrolytic acidification tank. Due to the limited capacity of the hydrolytic acidification tank, It is difficult to provide enough operating space, which brings many difficulties to the installation, adjustment and future maintenance of the equipment

(3) The single-hole reflective water distributor with reflective wings is made of stainless steel, which is expensive, so the initial investment and later operation and maintenance investment of the equipment are high, and the cost performance is low

(4) The water inlet pipe 2e is a closed pipe, and the accumulated water in the pipe cannot be discharged during maintenance, which affects normal maintenance
