What to do when anaerobic tower sludge is running

What to do when anaerobic tower sludge is lost? As we all know, high-efficiency anaerobic reactors are the core of wastewater treatment systems. In actual operation, abnormal situations such as the loss of anaerobic granular sludge often occur. Continuous sludge loss will inevitably lead to a decrease in the amount of sludge in the anaerobic reactor and a reduction in treatment capacity. Reasons for sludge loss: When the anaerobic reactor is operating normally, a small amount of dead metabolic anaerobic sludge will be lost with the water flow. If the loss is significantly greater than the sludge production, it is called "sludge loss", which requires special attention. There are many reasons for sludge loss. Common factors include: sludge voids, poor settling, excessively high upward velocity, biogas

Introduction to the characteristics of anaerobic tower components

The anaerobic tower consists of: barrier wells, equalization tanks, anaerobic tanks, anoxic tanks, two sedimentation tanks, contact oxidation tanks, etc. Each component plays an important role in the wastewater treatment process. Let's understand the function of each part: The function of the barrier well is to separate suspended solids and impurities from the wastewater to avoid later equipment processing. The function of the equalization tank: According to the characteristics of domestic water, the drainage time is uneven, and the drainage time in the morning, middle, and evening is basically fixed. The equalization tank can adjust the uneven water supply to ensure normal operation and adjustment of the swimming pool after treatment. A water level controller is set,

Introduction to Anaerobic Tower Operation and Management

When the concentration of treated wastewater is high (CODCr value greater than 5000mg/L), a reflux operation mode must be adopted. The reflux ratio is determined according to the specific situation. Effective reflux can not only reduce the influent concentration, but also increase the influent volume, ensuring uniform water flow distribution in the treatment facility and avoiding short water flow. Generally, it is difficult for industrial wastewater to reach 35℃, and heating is required (especially in winter). Therefore, in order to save energy for heating, on the one hand, attention should be paid to heat preservation (including increasing the reflux flow rate, etc.), and on the other hand, heat loss of the reactor should be prevented as much as possible. The sludge concentration in the reactor must be fully utilized.

The function and selection of a scraper

A sludge scraper is a machine used to remove sludge from channels. It is used in the larger diameter circular sedimentation tanks of urban sewage treatment plants, waterworks, and industrial wastewater treatment plants to remove sludge settled at the bottom of the tank and skim off floating scum. Hank Environmental Protection Company produces various types of sludge scrapers, including peripheral drive sludge scrapers, central drive sludge scrapers, central drive thickening sludge scrapers, central drive suspended sludge scrapers, gantry sludge scrapers, crane-type rake sludge scrapers, chain plate sludge scrapers, spiral conveying sludge scrapers, vertical center drive sludge scrapers, and parallel crane sludge scrapers.
