Description

A treatment device for pickling wastewater containing endocrine disruptors

technical field

The utility model belongs to the technical field of environmental protection of acid treatment waste liquid, more specifically, for marine engineering associated pickling liquid, the contained endocrine disruptor is used as a treatment device for persistent organic matter.

Background technique

The main methods currently available for pickling wastewater treatment are classified as follows:

Sulfuric acid pickling wastewater treatment processes mainly include neutralization method, ferric sulfate method, organic solution extraction method, dialysis method, ion exchange method and other methods. The latter three methods are still in the stage of experimental research. In addition, there are iron oxide red sulfur ammonium method, wetland method and biological method. In recent years, "zero discharge" of wastewater has been mentioned more and more frequently in the industrial field, and it has also become an important indicator in the planning review of various industries. With the progress of research, foreign countries have begun to use diffusion dialysis-diaphragm electrolysis, biosorption technology, micellar enhanced ultrafiltration and other processes to treat pickling wastewater containing endocrine disruptors.

Main process introduction

(1) Foam separation process: According to the principle of surface adsorption, foam separation uses the air bubbles formed in the liquid phase as carriers to separate the solute or particles in the liquid phase, so it is also called foam adsorption separation.

Foam separation technology is one of the new separation technologies developed in the past ten years. Foam separation is based on the principle of adsorption, to aerate the liquid containing surface active substances, so that the surface active substances in the liquid gather on the air-liquid interface (the surface of the bubbles), and form a foam layer above the liquid body, and separate the foam layer and The separation of the liquid phase main body can achieve the purpose of concentrating the surface active substance (in the foam layer) and purifying the liquid phase main body.

Foam separation consists of two basic processes: (1) the solute to be separated is adsorbed on the gas-liquid interface; (2) the substance adsorbed by the foam to the gas-liquid interface is collected and destroyed by chemical, thermal or mechanical methods. foam to extract the solute. Therefore, its main equipment is foam tower and foam breaker.

Foam separation technology has the following advantages:

(1) The foam separation structure is relatively simple and easy to scale up;

(2) Simple operation and low energy consumption;

(3) It can be operated continuously or intermittently;

(4) It is used in the initial stage of biological downstream processing to deal with bulky diluents;

(5) As long as the operating conditions are designed reasonably, high separation efficiency can be obtained.

After analyzing the characteristics of acidic wastewater containing endocrine disruptors and the feasibility of the foam separation process, the experiments were carried out. After the pickling wastewater was treated by foam separation, the COD concentration and the total P concentration were greatly reduced.

(2) Fenton oxidation process: Fenton reaction is a waste water treatment method in which ferrous ion (Fe ²⁺ ) is used as a catalyst to chemically oxidize hydrogen peroxide (H ₂ O ₂ ). The system composed of ferrous ions and hydrogen peroxide, also known as Fenton's reagent, can generate strong oxidative hydroxyl radicals, which can form organic free radicals with refractory organic substances in aqueous solution to destroy their structures, and finally oxidize and decompose.

The Fenton reaction is a series of free radical reactions catalyzed by ferrous ions. The main reactions are roughly as follows:

Fe ²⁺ +H ₂ O ₂ ＝＝Fe ³⁺ +OH-+HO·

Fe ³⁺ +H ₂ O ₂ +OH-==Fe ²⁺ +H ₂ O+HO·

Fe ³⁺ +H ₂ O ₂ == Fe ²⁺ +H ⁺ +HO ₂

HO ₂ +H ₂ O ₂ ＝＝H ₂ O+O ₂ ↑+HO·

Through the above reaction, Fenton reagent continuously produces HO (hydroxyl radical, electrode potential 2.80EV, second only to F2), which makes the whole system have strong oxidative properties, and can oxidize chlorobenzene, benzyl chloride, grease, etc. Oxidants (chlorine, sodium hypochlorite, chlorine dioxide, ozone, the electrode potential of ozone is only 2.23EV) oxidize substances. Under the action of hydroxyl radicals, some refractory organic matter in sewage is degraded into degradable organic matter, which improves the biodegradability of sewage.

(3) A ² /O process: A ² /O process is mainly composed of hydrolytic acidification pool, anaerobic pool and aerobic nitrification pool. As shown in Figure 1-1. Functions of each reactor unit:

1. Anaerobic reactor, the raw sewage and the phosphorus-containing return sludge discharged from the sedimentation tank enter simultaneously. The main function of this reactor is to release phosphorus and oxidize some organic matter at the same time;

2. Anoxic reactor, the primary function is denitrification, nitrate nitrogen is sent from the aerobic reactor through internal circulation, and the amount of mixed liquid in the circulation is relatively large, generally 2Q (Q is the flow rate of raw sewage);

4. Sedimentation tank, the function is to separate mud and water, part of the sludge is returned to the anaerobic reactor, and the supernatant is discharged as treated water.

Process features:

1. This process can be called the simplest simultaneous denitrification and phosphorus removal process on the system, and the total hydraulic retention time is less than other types of processes; the process efficiency can generally reach: BOD5 and SS are 90%-95%, total nitrogen more than 70%, phosphorus is about 90%;

2. Under anaerobic (anoxic) and aerobic alternating operating conditions, filamentous bacteria cannot proliferate in large quantities, and sludge filamentous expansion is not easy to occur, and the SVI value is generally less than 100;

3. The sludge contains high phosphorus and has high fertilizer efficiency;

4. No dosing is required during operation, and the two A sections only need to be gently stirred, so as not to increase dissolved oxygen, and the operating cost is low;

5. Anaerobic, anoxic, and aerobic three different environmental conditions and the organic combination of different types of microbial flora, and at the same time have the functions of removing organic matter, nitrogen and phosphorus.

(4) CMF process: continuous membrane filtration (Continuous Membrane Filtration, CMF for short) technology is a new type of membrane separation process, through a modular structure design, cross-flow filtration and intermittent automatic cleaning (gas, water washing process ) system, combined into a complete set of closed continuous membrane filtration system.

CMF system technical features:

1. High-strength polypropylene hollow fiber microfiltration membrane or ultrafiltration membrane is used, which is resistant to oxidation, easy to clean and has a long service life;

2. Due to the unique elasticity of the PP hollow fiber membrane, the micropores can be expanded, and the compressed air backwashing technology is used to make this membrane have a good membrane flux recovery rate;

3. Low requirements on raw water quality, clear and transparent produced water, stable SDI ≤ 3, which is better than the water inlet requirements of RO system;

4. The system control has a high degree of automation, simple operation, and effectively reduces labor intensity;

5. The equipment is compact in structure and occupies a small area, and the modular combination design is suitable for water treatment of various scales;

6. The equipment investment and operation costs are low, and the cost performance is the highest among the same type of equipment at home and abroad.
