1.Content wroks:1.1 Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse.1.2 Water supply refers to the delivery of treated water to users through public facilities or pipeline systems. This includes urban public water supply, private facility water
1. Functional agents and auxiliary agents 1.1 Functional agents remove specific pollutants, while other agents prevent scaling, defoaming and cleaning. Common functional agents in sewage treatment processes include ammonia nitrogen removers, phosphorus removers, heavy metal capture agents, decolorizers, defoamers, etc. 1.1.1 Decolorizers: In the process of industrial sewage treatment, sewage
1. The flocculant in sewage treatment often refers to polyacrylamide (PAM), which is a water-soluble high molecular polymer, insoluble in most organic solvents, has good flocculation, and can reduce the friction resistance between liquids. 2. PAM can be divided into three types: anionic polyacrylamide, cationic polyacrylamide, and nonionic polyacrylamide. 2.1.1
Commonly used chemicals for sewage treatment mainly include five categories: acid-base regulators, flocculants/coagulants, redox agents, functional agents (such as phosphorus removal agents, ammonia nitrogen removal agents, etc.) and auxiliary agents. Through physical and chemical reactions, pollutants are removed and water quality is discharged or reused in compliance with standards. 1.
What is Hydraulic Retention Time (HRT) ? Hydraulic Retention Time (HRT) refers to the average residence time of water or sludge in the treatment system in the reactor, that is, the average reaction time of sewage or sludge and microorganisms in the bioreactor. It is one of the important parameters
The anoxic/aerobic process is a sewage treatment method that connects the front anoxic section with the rear aerobic section in series . How does A/O works? The A/O process hydrolyzes organic matter such as starch, fiber, and carbohydrates in sewage through heterotrophic bacteria in the anoxic section to improve its
What’s the types of sludge? Sludge is a heterogeneous body composed of organic debris, bacteria, inorganic particles and colloids. It is difficult to separate solids and liquids thoroughly through sedimentation. The sludge produced by sewage treatment is a typical organic sludge, which is characterized by high organic content (60%~80%), fine
The pretreatment stage in sewage treatment is the key starting point of the entire treatment process, and its core goal is to create an environment suitable for subsequent biochemical treatment. The following provides an in-depth analysis from three dimensions: purpose, core technology, and implementation steps: 1、 The core objective of
Wastewater treatment is a systematic and complex process that typically includes pre-treatment, main treatment (including primary, secondary, and advanced treatment), and post-treatment stages. Each stage has different goals and technical means to ensure that the effluent quality meets standards. The following is a detailed processing procedure: 1、 PreprocessingGoal: Remove large
Recently, against the backdrop of the world’s growing attention to water resource protection and sewage treatment, Luckywater International and the Malaysian Water Association officially signed an agreement to jointly establish an international internship base for sewage treatment. This move marks a solid and important step for Luckywater International in combining international sewage
