Abstract

A comprehensive treating system for city sewage is composed of an admission water tank, a reactor with water inlet on its bottom, water outlet on its top, screen plate at said water inlet and three-phase separator at its water outlet, an adsorptive column with zeolite as its filler and the screen plates at its water inlet and outlet, and a treating water tank. Its advantage is high effect to remove COD, ammoniacal nitrogen and P.

Description

technical field [0001] The invention mainly relates to the field of environmental protection equipment, in particular to a comprehensive urban sewage treatment device. Background technique [0002] At present, compared with aerobic biological treatment technology, the advantages of anaerobic treatment are: (1) No oxygen supply is required, which saves operating costs; (2) The amount of sludge produced is 3 to 20 times less than that of aerobic process, and the sludge is easy to handle; (3) Less investment, easy maintenance, etc. Furthermore, the anaerobic process produces biogas, allowing the energy stored in the organic matter to be recovered. With the process of urbanization in China, the discharge of urban wastewater is increasing, and anaerobic reactors will also be widely used in the field of urban sewage treatment. [0003] Due to the lack of oxygen supply in anaerobic treatment, the ammonia nitrogen in the sewage cannot be converted into nitrate nitrogen and nitrite...
