Abstract
A process for treating industrial sewage, especially removing CODcr and NH3-N, features that the biologic carrier and composite microbes are proportionally added to original biologic treating apparatus and the sewage is treated in aerobic or anaerobic mode.
Description
Technical field:
The present invention relates to a kind of method of wastewater treatment, in specifically a kind of Industrial Wastewater Treatment with removing hardly degraded organic substance (CODcr), ammonia nitrogen (NH
3-N) method.
Background technology:
At present, most Industrial Wastewater Treatment still adopts traditional activated sludge process.People generally believe, in specific environment, as long as give time enough, will produce the flora that adapts to this environment most, and be the dominant microflora of surviving under this envrionment conditions, therefore, traditional active sludge is not to utilize the microorganism of pure culture, but the microbial population of self-sow is tamed, breeding utilizes.In wastewater treatment process, there are different types of microorganisms fellowships such as bacterium, fungi, protozoon to purify, because the metabolic process complexity, it is uneconomical that energy utilizes, and the microorganism antagonistic action that may exist, so processing efficiency is not high.When particularly running into the trade effluent of complicated type, poor effect, need to add some targetedly microbial strains improve the system handles effect.For example, the sewage works of Zhenghai, Ningbo GangWu Co., Ltd, the water outlet CODcr=100～150mg/l of former SBR device, in the SBR aeration tank, drop into effectively compound microbial after, the water outlet CODcr=69～94mg/l of SBR device.
In recent years, adding microorganism in wastewater treatment also brings into use, but mainly be to introduce more external microorganisms, jade as Japanese import is built bacterium, many employings add one type microorganism during use, and the content of bacterial classification is low, and removal effect improves limited, and need in treating processes, constantly add, become dominant bacteria in the system to keep the bacterial classification that adds.This dosing method is used in and causes owners' psychological burden in the engineering easily, worries the increase in the future of working cost.The ideal pattern should be once to add to meet the demands.
Summary of the invention:
The object of the present invention is to provide a kind ofly, realize the process for treating industrial waste water of a dosing method by uniting of the compound and bio-carrier of microorganism using two kinds of approach.
For achieving the above object, according to an embodiment of the present, the solution of the present invention is as follows: a kind of method of wastewater treatment is characterized in that: described method of wastewater treatment comprises following steps, and a, the waste water that needs to handle enter in the biological reaction tank by inlet channel; B, add the bio-carrier of 1～4% pool volume; C, compatibility complex microorganism; D, complex microorganism is dropped into biological reaction tank, the initial concentration that adds is a biochemical device volumetrical 3～6%; E utilizes aerated conduit to carry out aeration according to aerobic treatment process.
According to another kind of embodiment of the present invention, the solution of the present invention is as follows: a kind of method of wastewater treatment is characterized in that: described method of wastewater treatment comprises following steps, and a, the waste water that needs to handle enter in the biological reaction tank by inlet channel; B, add the bio-carrier of 1～4% pool volume; C, compatibility complex microorganism; D, complex microorganism is dropped into biological reaction tank, the initial concentration that adds is a biochemical device volumetrical 3～6%; E, utilize stirrer to stir according to double oxygen treatment process.
Wherein bio-carrier is a kind of porous particles material, and as activated carbon, the aperture of particulate matter is 20～100 orders.
According to the waste water object difference of handling, the composite bacteria kind that is adopted is also different with composition.
The common throwing bacterium method of this scheme and prior art relatively has the following advantages:
1. the microorganism that adds in handling waste water is domestic through secure authentication, does not have the problem of adventive invasion;
2. in handling waste water, add complex microorganism according to wastewater characteristics and processing back emission request, rather than single;
3. the complex microorganism that adds is liquid state, and initial concentration is a biochemical device volumetrical 3～6%;
4. add with bio-carrier, and only need once add.
