Solution Overview
Problem
Conventional biochemical reactors face challenges in efficiently circulating and distributing immobilized carriers due to buoyancy issues and shear stress, leading to uneven biodegradation and clogging problems, especially under high nitrite loading conditions.
Innovation Solution
A biochemical reactor design featuring a lower divider support structure with a circulation conduit and vanes that induce a helical pattern for carrier recirculation, along with perforated dividers to separate carriers from effluent, and a grating support structure to manage variable loads, ensuring uniform distribution and preventing carrier loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional impellers are used to stir and disperse immobilized carriers, then carrier distribution is improved, but carrier damage increases due to shear stress
Solution Approach 1:
The patent replaces the conventional mechanical impeller system with a circulation conduit system that uses fluid flow to achieve carrier dispersion and distribution, eliminating the source of harmful shear stress while maintaining effective carrier circulation throughout the reactor
Solution Approach 2:
The patent introduces a circulation conduit as an intermediary mechanism between the fluid flow and immobilized carriers, using the conduit to guide and distribute carriers through fluid motion rather than direct mechanical contact, thereby reducing carrier damage
2Productivity
If conventional reactors are used, then carrier circulation is achieved, but uniform distribution is poor under high nitrite loading conditions due to buoyancy
Solution Approach 1:
The patent utilizes hydraulic principles by designing a circulation conduit system that uses fluid flow dynamics to overcome the buoyancy effects of gas-produced carriers, ensuring uniform distribution of carriers throughout the reactor volume under high nitrite loading conditions
Solution Approach 2:
The patent addresses the two-dimensional surface accumulation problem by creating a three-dimensional circulation pattern through the circulation conduit, which draws carriers from the bottom and distributes them throughout the entire reactor volume, eliminating dead zones and ensuring uniform distribution
3Ease of operation
If conventional reactors are used, then carrier circulation is possible, but start-up operation is difficult due to carrier accumulation at the bottom
Solution Approach 1:
The patent incorporates a circulation conduit that is pre-configured to draw carriers from the bottom of the reactor during start-up operation, proactively preventing carrier accumulation and ensuring uniform distribution from the beginning of operation without requiring manual intervention
Solution Approach 2:
The patent creates a dynamic circulation pattern through the circulation conduit that actively moves carriers from the bottom accumulation zone to the upper reactor regions, transforming the static start-up condition into an active carrier distribution process that occurs automatically during operation
4Reliability
If perforated dividers are added to separate carriers from effluent, then carrier loss is reduced, but device complexity increases
Solution Approach 1:
The patent employs perforated dividers with optimized hole sizes that effectively retain immobilized carriers while allowing effluent to pass through, using porous material principles to achieve carrier separation without requiring complex mechanical components
Solution Approach 2:
The patent divides the reactor into distinct functional zones using perforated dividers, separating the carrier retention zone from the effluent discharge zone, which simplifies the overall system design by creating clear functional boundaries rather than requiring complex continuous separation mechanisms

Function Achieved in This Case
This design enhances the uniform distribution and longevity of immobilized carriers, improving biodegradation efficiency and reducing clogging and shear stress, thereby maintaining reactor performance under varying conditions.
Implementation Method 1
The one or more vanes may be configured to cause the immobilized carriers and the fluid exiting the circulation outlet opening to enter into a helical pattern as the immobilized carriers and the fluid recirculate through the tank
Implementation Method 2
The first divider may be disposed between the circulation inlet opening and the tank outlet for separating fluid from the immobilized carriers. The second divider may be disposed between the circulation outlet opening and the second end for separating fluid from the immobilized carriers
Implementation Method 3
The support structure may include a grating disposed between the second divider and the second end. The variable loads may include one or more pressures excreted by fluid within the tank and the circulation conduit
Implementation Method 4
Biodegradation within a biochemical reactor utilizing immobilized carriers may proceed as raw fluid or influent is fed to the reactor and stirred or agitated such that the liquid comes into contact with the immobilized carriers
