Abstract

The invention relates a gravity driven ultrafiltration biomembrane reactor device and a method for treating low-temperature low ammonia nitrogen waste water. The device aims to solve the problems that membrane pollution is serious, padding consumes the service life of a membrane and the energy consumption and the cost are high. The device comprises a stock solution groove, a water storage tank, a reaction tank, a collection tank, a stirring paddle, a membrane component, an aeration head, an air pump, a gas flowmeter, a liquid flowmeter, an overfall, a sewage discharge outlet, an air outlet, a first water pump, a second water pump, a plurality of valves, a plurality of water inlets and an electronic balance. The method comprises the following steps: firstly, pumping raw water into the water storage tank through a first water pump, and starting the stirring paddle; secondly, pumping uniformly mixed outlet water in the water storage tank into the reaction tank through the second water pump, ensuring that the water flows into the top of the reaction tank, starting the air pump to perform aeration through the aeration head, and controlling the pressure in the reaction tank by controlling the water inlet heat of the collection tank, so as to accomplish a gravity driven water treatment method.

Description

technical field [0001] The invention relates to an ultrafiltration biofilm reactor device and a method for treating low-temperature low-ammonia-nitrogen wastewater by using the device. Background technique [0002] In recent years, with the massive discharge of various drugs, fertilizers and domestic sewage, surface water has become more and more polluted. Ammonia nitrogen and organic pollutants have become important pollutants in water sources. Therefore, the removal of ammonia nitrogen and organic pollutants in water It has become a local problem of water supply in many places. The removal rate of ammonia nitrogen and organic matter by the traditional process is low, and the effluent is difficult to meet the requirements of the relevant national standards for drinking water quality. [0003] In particular, the treatment of low-temperature and low-ammonia-nitrogen concentration water is a hot and difficult issue in the field of water treatment. Low-concentration ammonia-ni...
