Problems solved by technology
[0003] However, due to the different amounts of sewage discharged from different sewage sources, a single sewage treatment system cannot be adapted to the sewage treatment of various sewage discharge sources, and the pre-production of various sewage treatment systems with different specifications not only requires more cost in design and production Large, and the treatment process for different sewage may also be different, so the adaptability of the pre-designed and produced treatment equipment will be problematic

The invention relates to an air-dissolving flotation device with a standard box, which includes a standard rectangular box, each of the two ends of the box is provided with three identical junction pipes (upper, middle and lower) with flanges, an air-dissolving releasing device is provided at the bottom of the box and a slag removing device is arranged at the top of the box. The air-dissolving releasing device is connected with a pressurized air-dissolving cylinder, the inlet of which is connected with one of the junction pipes of the box, a slag removing plate is arranged on the conveyer belt of the slag removing device, an upper junction pipe of the box is a slag hole, and an overflow weir matching with the slag removing device is provided in front of the slag hole, the lower junction pipe at the front end of the box is an water inlet and the lower junction pipe in the rear end is a water outlet. The floatation device has good floating effect and can be freely combined with other treatment unit with boxes of different specifications to form different treatment systems. The flotation device is favorable for reducing the cost, simplifying the installation and can guarantee the wastewater treatment effect.
Description
technical field [0001] The invention relates to sewage treatment equipment, in particular to a dissolved air flotation device using a standard box, which belongs to the technical field of environmental protection. Background technique [0002] For small-scale sewage discharges that often occur in life or production, especially in places far away from municipal pipes, it is necessary to set up a small sewage treatment system for sewage treatment to make it meet the discharge standards for on-site discharge. This type of small-scale sewage Due to the small processing capacity of the treatment system, the investment that can be borne is not large. Therefore, a finished product with wide adaptability and relatively low cost is required to produce a unified finished product in the factory without independent design for various specific sewage properties. and engineering construction. In view of the fact that such pollutants usually exist in sewage: floating substances such as oi...
