Problems solved by technology

According to reports, taking Shanghai as an example, there are currently about 29,000 restaurants, which discharge 17,000 tons of catering waste water per hour. In terms of oil indicators, about 15,000 tons flow into rivers every year. The pollution can be imagined. Even so At present, there are only more than a hundred restaurants implementing catering wastewater treatment. In addition to factors such as concept and policy strength, the lack of catering wastewater treatment equipment that is efficient, cheap, small in size, and easy to operate and manage is also a major reason

Abstract

A sewage treating system is composed of depositing pool, the floatation equipment consisting of tank body, supporting frame and electrode set which comprises base, insoluable plate anode and plate cathode made of stainless steel or graphite, and the aerating biological filter pool consisting pool body, filter layer, aerating pipe and active haydites in the pool. Its advantages are the integration of electrochemical treating, filter and biodegradation, small size and high effect.

Description

Technical field [0001] The invention relates to a sewage treatment system, in particular to a catering wastewater treatment system. Background technique [0002] At present, there are few technologies or equipments for catering wastewater treatment. Judging from the only technologies, they are mainly pharmaceutical coagulation air flotation, biological contact oxidation, SBR, activated carbon adsorption, etc. These treatment technologies are developed in response to the characteristics of restaurant wastewater, and therefore have certain effects. Under proper use and normal operation and management, they can basically meet the water quality discharge requirements of the "Integrated Wastewater Discharge Standard" GB8978-1996. However, because these technologies are generally suitable for large-scale wastewater treatment, for small-volume wastewater treatment projects such as restaurant wastewater, some defects are reflected to varying degrees, such as the traditional chemical coag...
