Embodiment Construction

[0031] like figure 1 In the working process of the microbial treatment of high-concentration ammonia-nitrogen wastewater device, the waste liquid storage tank 18, water inlet pump 24, reactor body 21, and treatment liquid collection barrel 20 are connected in series through pipelines to form a wastewater treatment process. The reflux pump 19 is connected in parallel with the reactor main body 21 , so that the treatment liquid circulates in the reactor main body 21 , that is, the treatment liquid flows back into the reactor main body 21 .

[0032] The process of the liquid to be treated in the reactor main body is as follows: enter the small area of ​​the first compartment of the reactor main body 21 from the liquid inlet 4, and due to the obstruction of the folded plate 8, the water flow first goes down from the top of the compartment and flows along the folded plate. Direction, from the gap between the folded plate 6 and the reactor bottom plate 3 into another large area of ​...

Abstract

The invention discloses an apparatus and a method for microbial treatment of high-concentration ammonia-nitrogen wastewater. The apparatus is composed of a reactor main body, a temperature controller, a pump, etc. The reactor main body is a cuboid structure and prepared by transparent synthetic glass or phenoplasts. The reactor main body is divided into 3-6 same compartments, and each compartment is divided into two regions of different sizes and is filled with zeolite, maifan stone and other natural minerals. One end of the reactor is provided with a liquid inlet while the other end is provided with a liquid outlet and a water collecting groove which is provided with two outlets: a water outlet and a backflow port. The reactor main body is nested in a water bath. A to-be-processed liquid is introduced into the reactor main body through a water pump, separated and degraded by microorganism, and then introduced into the water collecting groove through a drain outlet, wherein supernatant in the water collecting groove enters a liquid collecting barrel through the water outlet, and a sinking liquid flows back to the reactor main body through a reflux pump. A degradation process of the high-concentration ammonia-nitrogen wastewater can be realized under a temperature of 30-40 DEG C, a reflux ratio of 2-5 : 1 and a pH of 7.0-8.5.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a device for microbial treatment of high-concentration ammonia nitrogen wastewater. Background technique [0002] With the rapid development of my country's economic construction, the problem of water pollution has become increasingly prominent, the discharge of nitrogen pollutants has also increased, and the concentration of ammonia nitrogen in wastewater has also increased, resulting in eutrophication of water bodies and disrupting aquatic ecosystems. The dual pressure of water pollution and water shortage has seriously restricted China's economic and social development. [0003] There are physical methods, chemical methods, and biological methods for denitrification of wastewater. Among them, the biological method has the advantages of less energy consumption, lower cost, less by-products, and no secondary pollution to the environment. It is widely...
