"Junqi Fang" : An efficient upgrade solution for wastewater biochemical treatment driven by sponge biological fillers

I. Technical Principles and Filler Characteristics

(1) Microbial Flora and Degradation Mechanism
"Junqifang" employs a pre-culture technology of multi-functional bacterial communities to specifically domesticate a bacterial community system that includes aerobic bacteria (such as nitrifying bacteria, polyphosphate-accumulating organisms, heterotrophic bacteria) and anaerobic bacteria (such as denitrifying bacteria, methanogenic bacteria) based on the type of wastewater. This system can simultaneously and efficiently degrade pollutants such as carbon (COD, BOD₅), nitrogen (NH₃-N, TN), and phosphorus (TP) in wastewater. It comprehensively covers the entire process of wastewater biochemical treatment, including decarbonization, nitrification, denitrification and phosphorus removal.

(2) Structural advantages of sponge fillers
This filler is made of high-porosity reticular sponge material and features three core characteristics:

High specific surface area: The specific surface area of each cubic meter of filler exceeds 5,000 square meters, providing sufficient attachment space for microbial communities and ensuring a high biomass within the system.
Gradient microenvironment: The pores are interconnected, which not only facilitates the full mass transfer between sewage and the bacterial community but also forms a "aerobic - anoxic - anaerobic" microenvironment gradient, adapting to the coordinated metabolism of multiple bacterial communities.
Strong durability: The material is resistant to acid and alkali and anti-aging. When operating in the biochemical tank for a long time (service life ≥5 years), the structure remains stable and does not require frequent replacement.

Ii. The entire process of application implementation
(1) Preliminary research and plan customization
Water quality and quantity analysis: Detect the COD, BOD₅, NH₃-N, TP, pH and other indicators of the target sewage, calculate the daily treatment water volume, and determine the type of sewage (domestic sewage or industrial organic wastewater, such as wastewater from the food, printing and dyeing, and pharmaceutical industries).
Microbial community and dosage matching: Customize the microbial community formula based on the characteristics of water quality (for example, when treating high ammonia nitrogen wastewater, the proportion of nitrifying bacteria will be strengthened), and calculate the dosage through the "water quality - microbial community - filler" matching model. Generally, the dosage is 5%-10% of the effective volume of the biochemical tank.
(2) Pre-cultivation stage within the factory
In the standardized biological cultivation workshop, the manufacturer places the sponge filler into the simulated sewage reactor, inoculate the target bacterial community, and then adjust parameters such as dissolved oxygen, temperature, and nutrients to acclimate the bacterial community to a highly efficient and active stable period (with a COD removal rate of ≥80% and an ammonia nitrogen removal rate of ≥90% as the compliance standards), ensuring the maturity of the filler "biofilm formation".

(3) Transportation and on-site dosing
Constant-temperature and moisture-retaining packaging is adopted (the transportation temperature is controlled at 15-30℃ and the humidity is ≥80%) to ensure the activity of the bacterial community during transportation.
The "Bacterial Habitat Formula" can be directly added to the biochemical tank on site (select the aerobic tank, anaerobic tank or anoxic tank according to the process requirements), without the need for additional pretreatment steps.
(4) System Startup and Debugging
Within 1 to 3 days after addition, the biochemical system can achieve effective sewage treatment. By online monitoring of effluent COD, ammonia nitrogen and other indicators, and fine-tuning parameters such as aeration volume and hydraulic retention time, the system stability debugging was completed within 7 days.

Iii. Core Advantage Value
"Comparison dimension"

Traditional activated sludge process

"Junqi Fang" sponge filling method

System startup time

It takes 1 to 2 weeks to acclimate the sludge

Quick start within 1 to 3 days

Operating costs

Sludge needs to be added and relies on professional personnel for operation and maintenance

There is no cost for sludge addition, and labor costs are reduced by more than 50%

System stability

Sludge bulking and loss are prone to occur

The bacterial flora adheres to the packing material and has a strong ability to resist shock loads

Applicable scenarios

It has a low tolerance for fluctuations in influent water quality

Suitable for domestic and industrial sewage, resistant to fluctuations in water quality and quantity

In addition, "Junqi Fang" can reduce the production of excess sludge due to the attachment and growth of the bacterial community and the small amount of sludge shedding. This not only lowers the subsequent costs of sludge treatment but also avoids the environmental risks brought about by sludge disposal.

Iv. Typical Application Scenarios
(1) Construction of new sewage treatment plants
It replaces the traditional sludge cultivation process, shortens the project duration by more than 30%, and enables rapid compliance and acceptance after water supply. It is suitable for scenarios such as rural domestic sewage treatment plants and centralized sewage treatment facilities in industrial parks.

(2) Upgrading and renovation of existing sewage treatment plants
There is no need for large-scale renovation of the tank. Just by adding "Junqi Fang", the biochemical treatment efficiency can be enhanced, helping the effluent to upgrade from the first-level B standard to the first-level A standard. For instance, in the upgrading project of the wastewater treatment station of a certain printing and dyeing factory, the COD removal rate was raised from 75% to 92%.

(3) Treatment of industrial organic wastewater
For organic wastewater from industries such as food processing, brewing, and pharmaceuticals, customized bacterial communities are used to efficiently degrade characteristic pollutants. In a wastewater treatment project of a certain brewery, the degradation rate of organic substances in wort by "Junqi Fang" exceeded 95%.

(4) Emergency sewage treatment
In the face of sudden sewage leakage and temporary treatment needs (such as temporary sewage treatment for sports events), "Junqi Fang" can be quickly put into use to build a temporary biochemical treatment unit, achieving emergency sewage discharge up to standard.

V. Assurance and Service System
(1) Customized technical services
Pre-service: Provide water quality testing, solution design, and customized microbiota services;
Mid-term service: Provide on-site dosing guidance and system debugging training;
After-sales service: Regularly track the system operation data, provide optimization suggestions, and ensure long-term stable operation.
(II) Quality Assurance
Before leaving the factory, the "Junqi Fang" filler must pass dual tests on the activity of the bacterial community and the degradation efficiency of pollutants, and a test report must be issued to ensure the treatment effect after being put into use.

The "Junqifang" sponge biological filler, with its innovative model of "pre-cultivated bacterial colonies + porous carriers", reshapes the efficiency and stability of wastewater biochemical treatment, providing low-cost and easy-to-maintain solutions for wastewater treatment projects of different scales and types, and facilitating the efficient advancement of water environment governance work.
