I. Project Background and Objectives The coal chemical industry generates a large amount of wastewater in its production process, which contains high concentrations of inorganic salts, organic matter, ammonia nitrogen and other pollutants, posing a serious threat to the environment. In order to achieve clean production and environmental protection, a
1.1 Project Overview Drilling wastewater generation 610,000 tons/Years, approx.8 ton/h, which contains various salts, chemicals and petroleum residues. 1.2 Water quality analysis The main characteristic pollutants of the drilling wastewater provided by the owner are: oil,TDS, chlorides, etc. Due to the chlorides and TDS concentration up to 200000mg/L and 267588mg/L, biochemical treatment is no longer applicable. Therefore, the
1.1 Slaughterhouse Wastewater Water quality analysis Slaughter wastewater mainly comes from the slaughtering and processing of chickens and fish. A certain amount of wastewater is generated during the slaughtering process, cleaning after slaughtering, dismantling and washing, cleaning of internal organs and washing of the ground, as well as livestock manure. Wastewater
1. Process flow: divided into 5 stages 1) Pre-processing: ○ Screen: removes large suspended particles ○ Regulating pool: pH value adjustment ○ Coagulation and sedimentation: Add PAC+PAM to remove ss 2) Biochemical treatment ○ Hydrolysis and acidification: Improve the biodegradability of wastewater and decompose macromolecular organic matter ○ A2O: Remove
Wastewater treatment plants In cities, it is also called a sewage treatment plant or sewage plant. A treatment station is often located in a factory. When the effluent is placed in the city drainage pipe, the treatment station is actually a pre-treatment facility. A wastewater treatment plant is a complex
Sewage treatment equipment classification Sewage treatment equipment is the key equipment for treating and purifying sewage. According to different treatment principles and functions, sewage treatment equipment can be divided into many types. This article will introduce the classification of sewage treatment equipment in detail, including physical treatment equipment, chemical treatment
Wastewater treatment process Wastewater treatment refers to the process of treating polluted water through a series of complex processes to make it meet environmental discharge standards or reuse requirements. This process involves a combination of physical, chemical and biological treatment methods. The first step is to remove suspended solids, organic
The main steps of sewage treatment Wastewater treatment usually includes the following main steps: pretreatment,Biological treatment,Deep processing,Sludge treatmentThese steps work together to ensure that wastewater meets discharge standards or reuse requirements. Preprocessing Steps Pretreatment is the first step in sewage treatment. Its main purpose is to remove large particles and
(1) Ensure the quality of incoming water; (2) Ensure the quality of regeneration and extend the water production cycle; (3) Ensure the quality and purity of the regeneration liquid and strictly control the regeneration operating procedures; (4) Ensure that the equipment operates safely, reliably and normally.
(1) Water pH: If PAC is added and hydrolyzed to produce AI(OH)3 colloid, the dissolution is minimal when the pH is between 6.5 and 7.5, and the coagulation effect is also good; (2) Water alkalinity: When the alkalinity is insufficient, the coagulant will continuously produce H+ during the hydrolysis process,
