2 treatment process

The wastewater of this project is a high concentration organic wastewater, which can be biochemical and biochemical. The combination process of anaerobic UASB and good oxygen SBR was adopted.

The characteristics of wastewater suspension are more characteristic, and the two levels of pretreatment of grille and solid-liquid centrifuge are used to eliminate the influence of the following UASB.

3 process flow

This engineering process

Wastewater after fine grille to remove impurities, first through the solid liquid separator large particles suspended solids removal of wheat bran, into collecting well and the submersible sewage pump to ascend into adjusting pool, adjusting water quality after secondary to ascend into UASB reactor. After treatment of UASB reactor, the water outlet enters good oxygen SBR aeration tank, and after treatment, it is discharged. In the design, UASB is equipped with acid and alkali adjustment facilities. The residual sludge caused by aeration pool is pumped into the regulating pool, and the adjustment pool is raised to the anaerobic pool. The residual sludge discharged from anaerobic UASB pool enters the sludge thickening pool and is condensed and then dehydrated by the belt sludge dehydrator. The upper cleaning fluid and the dewatering machine room cleaning fluid flow back to the collecting well. Biological organic fertilizer is made after the treatment of the waste water after dehydration or compost.

In ancient times, humans did not have advanced water treatment techniques, and they were treated with simple grille interception and natural sedimentation in order to reduce the water spread of the disease. Then, after years of observation and summarization, they also found that the sand can be used to filter out the fine suspension, and then the coagulation pretreatment was developed. With the continuous progress of human civilization, human waste and the destruction of the environment have caused serious pollution of water resources. When all kinds of infectious diseases pass through water and cause many people to get sick or die, it is important to find out what water treatment is. It is only then that people begin to study water treatment technology.

Since the end of the 19th century, industrial technology has come a long way, and industrial sewage has been doubling every year. Moreover, the rivers and lakes of the industrial powers were severely polluted and gradually became a public nuisance. The discovery of simple chemistry, physical methods and the difficulty of dealing with them has led to new water treatment techniques. Scientists of all countries have begun to study water treatment method, is the earliest sewage aeration experiment, then the biological membrane method, then is the artificial biological treatment method, and then to now targeted ion exchange method, electrochemical processes, such as high and new technology.
