Problems solved by technology

[0003] The stripping method is suitable for the primary treatment of high ammonia nitrogen wastewater. This method is mature and simple, but the operating cost is high, the equipment is corroded seriously, and it is easy to cause secondary air pollution.
The adsorption method utilizes the strong selective adsorption capacity of modified natural zeolite for ammonia nitrogen, which has the characteristics of high efficiency and small equipment volume, but frequent regeneration and complicated operation and management
The chemical oxidation method, chemical precipitation method, electrolysis method and ion exchange method in the chemical method, although the process and equipment are simple and the reaction is fast, the treatment cost is high or the power consumption is large
When biological methods remove ammonia nitrogen in wastewater, neither the single aerobic biological method nor the single anaerobic (anoxic) biological method can directly convert ammonia nitrogen into nitrogen, while traditional methods generally use anaerobic biological treatment based on aerobic biological treatment Ammonia nitrogen can be converted into nitrogen only through anoxic treatment or anoxic treatment. Therefore, the traditional method has the problems of many structures, large investment in equipment, difficult control of aerobic conditions, and high energy consumption.

Abstract

The invention discloses an integrated high-ammonia-nitrogen wastewater biological removal reaction filter column, which adopts an upflow operation mode, water is fed from the bottom, and water is discharged by gravity at the top. Dimensional packing, the bottom of the filter column is equipped with a multifunctional cone area, and microporous adjustable aeration devices, water inlets and sludge discharge outlets are arranged to cultivate and maintain short-range nitrification activated sludge, and at the same time accept the biofilm from the filter material area and discharge it Excess residual sludge. The device has perfect technology, small footprint, simple and flexible operation, low cost, and stable and good removal effect on ammonia nitrogen in wastewater. Effective removal of other high ammonia nitrogen wastewater.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and development, and relates to a novel high ammonia nitrogen wastewater treatment system, in particular to an integrated high ammonia nitrogen wastewater biological removal reaction device. Background technique [0002] High ammonia nitrogen wastewater mainly comes from wastewater discharged from petrochemical, aquaculture, animal husbandry, meat processing and other industries, as well as municipal solid waste leachate. The harm of ammonia nitrogen to the environment is mainly that after entering the water body, it becomes the nutrient element of algae and other organisms, causing the algae to multiply in a short period of time, consuming dissolved oxygen in the water, causing eutrophication of the water body, and destroying the aquatic ecosystem. Ammonia nitrogen in water can be converted into nitrite under certain conditions, which seriously endangers aquatic organisms and hum...
