Sludge Addition Of The Fruit Processing Wastewater - China

The project has a design scale of 30, 000t/d.

The wastewater comes from the fruit processing process and belongs to high-concentration organic wastewater.

The influent CODcr is 40, 000-50000 mg/L, and the SS is 30, 000-50000 mg/L.

It has the characteristics of high CODcr concentration, high suspended solids, and good biodegradability.

The treatment goal of this project is to meet the first-level standard of "Integrated Wastewater Discharge Standard" (GB 8978-1996); add 2500 tons of Shanghai Chunxun biological anaerobic granular sludge; build 10 2000 m3 IC anaerobic reactors, COD The removal rate is over 90%, and the daily biogas production is 120, 000 m3 - How does anaerobic wastewater treatment work?

The anaerobic wastewater treatment process consists of two stages.

1 - Acidification stage: In this initial stage, anaerobic bacteria break down complex organic compounds into acids or short-chain volatile acids.

2 - Methane production stage: The second stage consists of two steps.

● Acetate-producing anaerobic bacteria synthesize acids to form acetate, carbon dioxide, and hydrogen gas.

● Methanogenic anaerobic bacteria will act on the newly produced molecules to form carbon dioxide and gas.

The by-products can be used as fuel if desired, while the effluent is used for further treatment or discharge.

Anaerobic treatment systems can be designed and configured as single-stage or multi-stage units, depending on the application and requirements of the facility.

Basically, the anaerobic treatment cycle involves the wastewater entering a bioreactor vessel that contains a thick semi-solid material called sludge filled with anaerobic bacteria and other microorganisms that break down the organic pollutants present in the wastewater.

Advantages of anaerobic wastewater treatment

Anaerobic wastewater treatment systems have several advantages over aerobic systems.

● Sludge treatment and disposal costs are 6 to 8 times lower than aerobic processes due to biomass production.

● Lower nutrient replenishment costs due to lower biomass production, which requires less nutrients.

● The anaerobic system requires less energy to operate.

● A small reactor surface is required because the anaerobic process can handle higher volumetric loading rates with a small reactor volume.

● The biomass produced by the anaerobic system is an alternative fuel.

● Rapid response to substrates after long shutdowns.
