MBR membranes are classified into ultrafiltration membranes and microfiltration membranes according to their pore sizes, and are divided into hollow fiber membranes, tubular membranes, and flat membranes according to their physical forms. Hollow fiber membranes are divided into curtain membranes and column membranes, and lined membranes. Hollow fiber membrane and hollow fiber membrane without lining

Due to the particularity of its water quality, catering wastewater treatment methods are generally divided into two stages: pretreatment and treatment. In practical applications, multiple technologies are often used in combination. The main goal of treatment is to remove COD and suspension from catering wastewater. And animal and vegetable oils. Preprocessing is the basis of the processing process, and processing is the depth of the preprocessing process.

Excessive phosphorus, nitrogen and other elements in the water will accelerate the eutrophication of the water body. This phenomenon is more serious in China and has brought great harm to industry, aquaculture, agriculture and tourism. The increase of nitrogen, phosphorus and other nutrients is the reason for the large number of algae reproduction. Among them, phosphorus is the key factor. Therefore, how to effectively reduce the concentration of phosphorus in sewage

According to the classification of sewage sources, sewage treatment can be divided into two categories: domestic sewage treatment and wastewater treatment. Sewage treatment is wastewater generated from daily life of sewage treatment. It mainly refers to the suspension and floating of various organic and inorganic compounds and mixtures, including solid particles in pure solutions, and various gels and gel diffusion.

Chemical pharmaceutical wastewater has high COD and BOD values, some as high as tens of thousands or even hundreds of thousands, but the B / C value is low. Once the wastewater is discharged into the water body, it will consume a large amount of dissolved oxygen in the water, causing the water body to lack oxygen. At the same time, the composition of wastewater is complex and changes widely, with a wide variety of organics, high concentrations, and imbalanced nutritional elements.

Air floatation filter integrated machine is a system specially designed to remove grease, glue and solid suspended solids in catering sewage. Air floatation filter integrated machine integrates air floatation, filtration and adsorption, and separates oil and water, suspended matter, The removal of COD and BOD has a good effect to make the sewage treatment reach the discharge standard, thereby reducing the sewage costs.

First, mechanically remove impurities from restaurants and restaurants' directly recovered catering wastewater to remove large impurities such as bones, vegetables, and even cloth strips for washing, as well as impurities such as starch, protein, sugars, detergents and colloidal substances. The liquid portion is then subjected to oil-water separation.

The COD of tannery wastewater is generally in the range of 3000 ~ 4000 mg / L, which has good biochemical properties. After the wastewater treatment process, the general effluent requirements meet the national standard of secondary standards (COD <300 mg / L), but there are also some sewage treatment stations. Operation needs to meet stricter emission standards.

The anaerobic internal circulation reactor, referred to as IC reactor, is a new type of reactor based on the concepts of UASB reactor granulation and three-phase separator. The IC anaerobic reactor divides the biogas separation into two stages in a high reactor. The bottom one is under extreme high load, on the
