Solution Overview

Problem

Existing wastewater purification systems, such as those using flexible film partition walls and requiring pumps for transferring wastewater between treatment portions, suffer from inefficiencies and limited treatment efficiency.

Innovation Solution

A wastewater purification apparatus utilizing hyperboloid agitators rotating in opposite directions within a single tank to create distinct treatment zones without physical partitions, enabling continuous or batch processing with controlled wastewater flow and aeration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If partition walls are used to divide treatment portions, then distinct treatment zones can be created, but the apparatus requires pumps and lines for wastewater transfer and has reduced treatment efficiency

Engineering Contradiction:
Improvetreatment efficiencyVSAvoidcomplexity of pumps and lines
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention removes the partition walls from the treatment tank, extracting the physical barrier that required pumps and lines for wastewater transfer. The tank becomes a single continuous space where wastewater flows freely from the inlet through multiple treatment portions to the outlet, eliminating the need for complex transfer mechanisms while maintaining distinct treatment zones through controlled aeration and agitation patterns.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention enables continuous wastewater flow through the entire treatment tank without interruption by pumps or transfer lines. Wastewater continuously moves from the inlet through the treatment portions to the outlet, allowing uninterrupted treatment operation. The system maintains continuous aeration and agitation throughout the treatment portions to ensure ongoing purification effectiveness.

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If partition walls are used to create treatment portions, then different treatment steps can be implemented, but the apparatus cannot achieve continuous purification

Engineering Contradiction:
Improvecontinuous purification capabilityVSAvoidsimplicity of tank structure
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The invention extracts the partition walls that interrupted continuous flow, creating an open tank structure. This allows wastewater to flow continuously from the inlet through multiple treatment portions to the outlet without being diverted or stored between sections, enabling continuous purification operation while simplifying the tank structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention segments the treatment process into distinct portions within a single continuous tank space. Different treatment steps (aeration, settling, biological treatment) are implemented in different zones of the tank through localized aeration devices and agitators, allowing continuous purification while maintaining operational simplicity through a unified tank structure.

Inventive Principle:
Principle #1Segmentation

3Productivity

If pumps and lines are used for wastewater transfer, then treatment portions can be connected, but treatment efficiency is reduced

Engineering Contradiction:
Improvetreatment efficiencyVSAvoidnumber of pumps and lines
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention removes all pumps and transfer lines from the system, extracting the mechanical components that reduced treatment efficiency. Wastewater is transferred between treatment portions through natural gravity-driven flow in the open tank, eliminating energy losses and efficiency reductions associated with mechanical pumping and line transfers.

Inventive Principle:
Principle #2Taking out (Extraction)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enhances wastewater purification efficiency by allowing continuous operation, reducing the need for pumps and lines, and enabling varied treatment conditions within the tank's zones.

Implementation Method 1

As a hyperboloid agitator body rotates, a flow forms which is directed along the agitator shaft in the direction of the hyperboloid agitator body. The flow deflects at the surface of the hyperboloid agitator body in a substantially horizontal direction. At a certain distance from the peripheral edge of the hyperboloid agitator body, the flow then deflects again in a vertical direction towards the surface of the wastewater.

Methodology Applied
Scientific EffectCirculating flow: Convection

Implementation Method 2

aeration device with a fan for aerating wastewater received in the tank

Methodology Applied
Scientific EffectAeration: Aeration

Implementation Method 3

a decanter, which is provided for discharging purified wastewater in a third treatment portion

Methodology Applied
Scientific EffectSedimentation: Sedimentation
