Problems solved by technology

Now the common method of treating acid-base wastewater is to use neutralizer to carry out acid-base neutralization method, flocculation method and chemical precipitation method, all of which directly put a certain amount of compounds into the aeration tank for neutralization, but because the sewage in the aeration tank For aeration reaction with sludge, the pH of the mixed solution is always in a state of change. Therefore, none of the above methods can accurately release the corresponding amount of compounds according to the pH value, which is easy to cause waste of raw materials, and when the initial dosage is insufficient, The subsequent discharge will be acid-alkaline sewage, which will seriously pollute the environment

Embodiment 1

[0025] Example 1: figure 1 It is a flowchart of the sewage treatment method of the present invention. refer to figure 1 As shown, the present invention provides a sewage treatment method for automatically regulating pH, which specifically includes the following steps.

[0026] S1: Precipitate and filter the sewage, specifically: filter with a grid to remove massive impurities, and then use a microbial flocculant for flocculation and sedimentation. On the one hand, the sewage is effectively precipitated, and on the other hand, the microorganisms in the sewage are increased. Content, that is to say, it increases the opportunity for microorganisms in the subsequent aeration tank to contact with organic matter and dissolved oxygen, improves the aerobic decomposition efficiency of organic matter in the sewage in the aeration tank, and is non-toxic, eliminating secondary pollution. It can be understood that while using the microbial flocculant, the amount of activated sludge in th...

Embodiment 2

[0033] Example 2: The conditions of Example 1 (including flocculant, amount of sewage, amount of activated sludge, aeration tank size, aeration rate, etc.) are the same, only the detection time is changed, that is, the number of detections is changed, that is, The number of times the neutralizer is administered.

[0034] This example provides a sewage treatment method for automatically regulating pH, which specifically includes the following steps.

[0035] S1: Precipitate and filter the sewage, specifically: filter with a grid to remove massive impurities, and then use a microbial flocculant for flocculation and sedimentation. On the one hand, the sewage is effectively precipitated, and on the other hand, the microorganisms in the sewage are increased.

Embodiment 3

[0039] Example 3: The conditions of Example 1 (including flocculant, amount of sewage, amount of activated sludge, aeration tank size, aeration rate, etc.) are the same, only the detection time is changed, that is, the number of detections is changed, that is, The number of times the neutralizer is administered.

[0040] This example provides a sewage treatment method for automatically regulating pH, which specifically includes the following steps.

[0041] S1: Precipitate and filter the sewage, specifically: filter with a grid to remove massive impurities, and then use a microbial flocculant for flocculation and sedimentation. On the one hand, the sewage is effectively precipitated, and on the other hand, the microorganisms in the sewage are increased.

Abstract

The invention relates to a sewage treatment method and system capable of automatically regulating and controlling a pH value. The sewage treatment system mainly comprises an aeration device, a pH value sensor, a hopper, a valve, a flow meter and a control system. The pH value sensor is used for detecting the pH value of sewage in real time; moreover, quantitative feeding of a neutralizer is realized through the control system, so resource cost is saved, and the acid-base sewage is comprehensively purified; and an existing aeration device is improved, so the neutralizer can be released from thebottom of an aeration tank by utilizing air, and the efficiency of a neutralization reaction is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment method and system for automatically regulating pH. Background technique [0002] With the vigorous development of industry, more and more waste water is produced. Acid-base waste water is a kind of harmful waste water. If it is directly discharged into drainage pipes or water bodies without treatment, it will damage pipes and underground structures and pollute water bodies. . Therefore, after passing the wastewater test, the unqualified wastewater must be treated to meet the national or local discharge standards before it can be discharged. Now the common method of treating acid-base wastewater is to use neutralizer to carry out acid-base neutralization method, flocculation method and chemical precipitation method, all of which directly put a certain amount of compounds into the aeration tank for neutralization, but because the sewage in t...
