Wastewater treatment equipment for domestic use

Product overview

Domestic sewage refers to the wastewater discharged by residents in their daily lives. It mainly comes from residential buildings and public buildings, such as houses, offices, schools, hospitals, stores, public places and industrial enterprise bathrooms, etc. The pollutants contained in domestic sewage are mainly organic substances (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.)

Performance Introduction

Domestic sewage refers to the wastewater discharged by residents in their daily lives, mainly coming from residential buildings and public buildings such as houses, offices, schools, hospitals, stores, public places and industrial enterprise bathrooms, etc. The pollutants contained in domestic sewage mainly consist of organic substances (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.). The organic substances present in domestic sewage are extremely unstable and are prone to decay, generating a foul smell. Bacteria and pathogens multiply in large numbers using the organic substances in domestic sewage as nutrients, which can lead to the spread and prevalence of infectious diseases. Therefore, domestic sewage must be treated before being discharged.

Wastewater characteristics

The main sources include urban domestic sewage, hospital sewage, garbage and surface runoff, etc. The characteristics of pathogenic microorganisms are as follows: ① large quantity; ② wide distribution; ③ long survival time; ④ rapid reproduction; ⑤ prone to developing resistance and difficult to eliminate; ⑥ after traditional secondary biochemical wastewater treatment and chlorine disinfection, some pathogenic microorganisms and viruses can still survive in large numbers; these pollutants actually enter the human body through multiple pathways and survive within the body, causing human diseases.

Conventional methods for wastewater treatment

Both domestically and internationally, the biochemical method is generally adopted for treating domestic sewage. This is because the ratio of BOD5 to CODcr in domestic sewage is approximately 0.5, indicating a strong biodegradability. The contact oxidation method has the advantages of high volumetric load, short residence time, good organic matter removal effect, simple operation and small land occupation area. Therefore, we chose the contact oxidation method, which is mature in technology and reliable in operation.

The third-generation intelligent biochemical integrated equipment for domestic sewage, independently developed and produced by Baohupu, features efficient treatment, energy conservation and environmental protection, the ability to be buried underground, small floor area, simple commissioning and stable operation.
