Abstract

The invention discloses a combined processing method aiming at high ammonia nitrogen source water. According to the method provided by the invention, a combined processing system is adopted, any two or more processes of biological pretreatment, coagulating sedimentation, post-ozonation, carbon-sand filtration and membrane treatment are combined for processing the high ammonia nitrogen source water, wherein the combined processing system selects two or more from a bacteria filter unit, an inclined-tube settling unit, a carbon and sand filter unit and an ultrafiltration membrane unit for combination, the inlet of the combined processing system is connected with source water, and the outlet of the combined processing system is communicated with a clean water tank. According to the combined processing method provided by the invention, biological filtration, flocculation inclined tube sedimentation, ozone contact, carbon sand filtering and ultrafiltration membrane processing technologies are in collaboration, through superimposition design of all units of the combined system, at the aim of high ammonia nitrogen source water difficult to process conventionally, under the premise of guaranteeing yielding water to meet the yielding water quality standard, pharmaceutical dosage and disinfector dosage in water works are reduced, and the combined processing method has obvious advantages that yielding water quality is improved, occupied area is reduced, and medicaments are reduced.

Description

technical field [0001] The invention belongs to the field of water supply engineering, and relates to a high-efficiency water treatment combined method, specifically, to a combined treatment method applied to high ammonia nitrogen raw water, and adopts a group of biological filters and inclined pipes according to the water quality characteristics of high ammonia nitrogen raw water New combined treatment method of sedimentation, carbon sand filter and ultrafiltration membrane system. Background technique [0002] According to relevant reports, ammonia nitrogen in water mainly comes from domestic sewage, industrial waste and chemical fertilizers. With the rapid development of industrialization and urbanization in our country, the excessive phenomenon of ammonia nitrogen in surface water frequently occurs. Due to the nitrification of ammonia, high concentrations of ammonia nitrogen in tap water may produce carcinogenic nitrite nitrates that threaten health, and raw water with ...
