Industrial sewage treatment equipment

   Industrial sewage treatment equipment It's what we call sewage treatment equipment. This is what everyone calls it. It's a matter of personal preference. When it comes to industrial wastewater, it has to be mentioned that this range is a little wide. High concentration wastewater, high COD and ammonia nitrogen, oil, medicine, chemical industry, breeding, slaughtering, printing and dyeing, medical treatment, spraying, wine making, papermaking, tanning, food processing, landfill leachate, animal harmless treatment and so on are all included in the industrial wastewater.

 industrial waste water

In the industrial sewage treatment system, the stable operation of process equipment is an important prerequisite for the stable operation of the system. If the equipment fails, it will inevitably affect the normal operation of the sewage treatment station, and seriously may cause the sewage treatment plant to stop running. This will affect the production of the workshop and cause serious losses. Therefore, the management personnel of sewage treatment station should pay attention to the management and maintenance of sewage treatment equipment, and reduce the probability of equipment failure.

Industrial sewage treatment is different from domestic sewage treatment, and there are many kinds of industrial wastewater. Different factories will produce different wastewater, even in the same factory and different workshops will produce different wastewater, so it is difficult to use a unified method to classify it. According to our own experience, the wastewater from printing and dyeing industry can be divided into wastewater from production, acid-base wastewater and pharmaceutical wastewater according to their own experience.

It is very important to know the type and concentration of pollutants in wastewater for the collection and treatment of wastewater, the design and operation of wastewater treatment facilities, and the detection of environmental quality. Therefore, we must understand the types and composition of wastewater, so as to take appropriate treatment methods to treat it and reduce the harm to the environment. According to the types of pollutants in the wastewater and the harm to the environment, we divide the wastewater into ten types: solid pollutants, aerobic pollutants, oil pollutants, toxic pollutants, organic pollutants, biological pollutants, acid-base pollutants, nutritional pollutants, sensory pollutants and thermal pollution.

 Comparison of industrial wastewater treatment effect

We have corresponding treatment processes and solutions for different wastewater. Let's take a look at several common wastewater:

Characteristics of petrochemical wastewater

Petrochemical wastewater is characterized by complex varieties, disorderly composition, high toxicity, inhibition of biodegradation and high concentration

1. Large amount of water, disordered and changeable water quality

The production scale of petrochemical industry tends to be large-scale. In the process of production, various solvents, additives and additives are required, and then various reactions are carried out. Therefore, the amount of sewage is large and the composition is appropriate and disorderly.

2. Serious organic pollution

The main organic compounds in petrochemical wastewater are hydrocarbons and their derivatives. The COD of high concentration waste liquid discharged from some petrochemical equipment is still high after combustion or other appropriate treatment.

3. The sewage contains heavy metals

Because many reactions in petrochemical production are completed under the action of catalysts, a large petrochemical plant can use dozens of catalysts, so the sewage often contains heavy metals.

Petrochemical wastewater treatment process

At present, according to the treatment principle, all treatment methods can be divided into physical treatment, chemical treatment and biochemical treatment.

The general treatment process of oily wastewater is as follows:

 Petrochemical wastewater treatment process

Aquaculture wastewater treatment and discharge process

In the area with limited carrying capacity of livestock and poultry in ploughing field, the large-scale planned breeding farm controls the amount of fecal water and pollutant concentration; after anaerobic, aerobic biochemical treatment, advanced treatment and natural treatment such as oxidation pond and constructed wetland, the effluent quality meets the national discharge standard and total amount control requirements; solid manure is produced by composting and fermentation.

The process flow is as follows

 Aquaculture wastewater treatment process

Anoxic aerobic process is selected in this scheme, which can achieve good treatment effect. It is a simple, efficient and low energy consumption biochemical treatment method for high concentration organic wastewater. It has the following advantages:

A. the process is simple, the remaining sludge disposal is less troublesome, and the investment is saved.

B. low investment, less land occupation and low operation cost.

C. in the reaction process, the substrate concentration gradient is large, the reaction driving force is large, and the efficiency is high.

D. It is resistant to the impact of organic load and toxic load, and the operation method is sensitive, so the static sedimentation is caused, so the water outlet function is good. E. The process of anoxic and harmonious oxygen replacement, short sludge age, high activity, has a good effect of nitrogen and phosphorus removal.

According to the advantages of the method, the method has been developed and used in organic wastewater treatment at home and abroad. It is more sensitive and stable than activated sludge process.

(4) low energy consumption and low operation cost: the scheme strengthens the pretreatment and anaerobic treatment, so that the pollution can be greatly removed before the aerobic treatment, so as to reduce the load of aerobic biochemical treatment and save energy together.

(5) choose safe, reliable and advanced technology of chloroprene tablets disinfection skills: the advantages of simple operation and low investment. In addition, the transportation and storage of materials are safe and convenient, and there is no toxic chlorinated organic matter in the disinfected wastewater.
 

The above briefly introduces the process and solution of several process wastewater, more wastewater can be treated by us. Our company is equipped with sewage laboratory, and we can get water samples for experimental treatment, and study the suitable process and process. We also hope to use our own professional technology to solve the problem of sewage.
