Summary of AO process operation control indicators

2024-01-08

The operation of sewage treatment requires the reasonable regulation of numerous control parameters, only in this way can the normal and efficient operation of the treatment process be guaranteed. This article provides a detailed introduction to the control of the main parameter indicators of AO (denitrification) process.

Key points for sludge addition and start-up in anaerobic reactors

2024-01-05

The start-up of anaerobic reactors usually requires the addition of anaerobic granular sludge, with an inoculation amount of approximately 10-15%. However, many environmental protection companies, in order to save costs, will require on-site debugging personnel to use activated sludge to domesticate granular sludge.

Comprehensive Explanation of the Principles of Anaerobic Wastewater Treatment

2024-01-03

In the process of sewage treatment, anaerobic biological treatment of wastewater is also known as anaerobic digestion or anaerobic fermentation in the early stages; It refers to the process in which organic matter is decomposed and produces CH4 and CO2 under anaerobic conditions by the combined action of multiple (anaerobic or facultative) microorganisms.

Evaluation and selection of pretreatment process before ultrafiltration

2024-01-02

If the pollutants in water are mainly microorganisms and particulate matter, usually only a small amount of pre-treatment measures are needed before ultrafiltration. Generally, pre filters (100-300) are installed upstream of the ultrafiltration process μ m) Removing larger particulate matter is sufficient, such as using self-cleaning filters, bag filters, filter cartridges, or disc filters.

The problem of industrial waste salt and its resource utilization approaches

2023-12-29

Industrial waste salt usually refers to solid waste generated in the industrial production process, mainly composed of inorganic salts. These wastes mainly come from multiple industries such as high salt wastewater treatment and pesticide production. According to statistics, China produces over 2.0 industrial waste salts annually × 107t, most of which comes from the production of pesticides and dyes.

A New Process for Pharmaceutical Wastewater Treatment

2023-12-27

Pharmaceutical industrial wastewater mainly includes antibiotic production wastewater, synthetic drug production wastewater, traditional Chinese patent medicines and simple preparations production wastewater, and washing water and flushing wastewater in the production process of various preparations. The characteristics of its wastewater are complex composition, high organic content, high toxicity, deep color and high salt content, especially poor biochemical properties and intermittent discharge, making it difficult to treat industrial wastewater.
