At present, the sewage treatment process of pharmaceutical factories is the best

Treatment process and selection of pharmaceutical wastewater.

The water quality characteristics of pharmaceutical wastewater make it impossible for most pharmaceutical wastewater to be treated by biochemical treatment alone, so necessary pretreatment must be carried out before biochemical treatment. Generally, a regulating tank should be set up to adjust the water quality, quantity and pH, and a certain physicochemical or chemical method should be used as a pretreatment process according to the actual situation, so as to reduce the SS, salinity and part of the COD in the water, reduce the bioinhibitory substances in the wastewater, and improve the degradability of the wastewater, so as to facilitate the subsequent biochemical treatment of the wastewater.

After pretreatment, the wastewater can be treated by an anaerobic and aerobic process according to its water quality characteristics, and if the effluent requirements are high, post-treatment needs to be continued after the aerobic treatment process. The selection of specific processes should comprehensively consider the nature of wastewater, the treatment effect of the process, infrastructure investment, operation and maintenance and other factors, so as to be technically feasible and economically reasonable. The general process route is a combination of pre-treatment, anaerobic, aerobic (post-treatment) processes.

For example, Chen Minghui et al. [28] used a combined process of hydrolysis adsorption, contact oxidation, and filtration to treat comprehensive pharmaceutical wastewater containing artificial insulin, and the effluent quality after treatment was better than the first-class standard of GB8978 1996. Good treatment results have been achieved in the treatment of chemical and pharmaceutical wastewater by air flotation hydrolysis and contact oxidation process, the treatment of antibiotic wastewater by composite micro-oxygen hydrolysis and composite aerobic sand filtration process, and the treatment of high-concentration traditional Chinese medicine extraction wastewater by air flotation UBF CASS process.

Look at the salt, whether the sulfate is high or not, if it is a fermented COD, it is anaerobic.

There are many chemicals used in sewage treatment in pollution treatment plants, and the specific chemicals used are iron salts for general coagulation and precipitation, aluminum salts for air flotation, and polymers for coagulants (many types).

Sulfites are used for reducing agents, ozone is used for oxidants, chlorine dioxide, sodium hypochlorite, etc., activated carbon or anionic resin is used for adsorbents, quartz sand, activated carbon, ceramsite and organic synthetic parts (including ultrafiltration membranes, reverse osmosis membranes and MBR membranes) are used for filtration. Different chemicals are used according to different sewage.

The future development direction of water treatment chemicals:

1. The specificity of water treatment agents should be improved, so that users can choose according to industry classification, and avoid poor use results caused by wrong selection.

2. Research and development of multi-functional water treatment agents and expand the scope of use of agents.

3. The development of green water treatment agents is the inevitable trend of future development, with the continuous improvement of people's awareness of environmental protection, green, environmental protection and energy saving have become one of the criteria for users to choose to use, so in order to occupy a dominant position in the market, we must reduce the pollution caused by the use of chemicals, and finally achieve the goal of zero pollution.

Water treatment agents are in the greatest demand

Municipal water treatment is the area with the largest demand for water treatment agents in China, and in 2020, municipal water treatment accounted for 30% of China's water treatment agent application market.

Domestic water consumption has increased overall

According to the data of the National Bureau of Statistics, from 2016 to 2019, China's total domestic water consumption increased year by year, reaching 100 million cubic meters in 2019 and slightly decreasing to 100 million cubic meters in 2020. On the whole, China's domestic water consumption is on the rise.

Increased wastewater treatment capacity

With the acceleration of urbanization, the increase of urban population, and the increase of domestic water consumption, the amount of domestic sewage produced has gradually increased, and the treatment of urban domestic sewage has become a topic of increasing concern. In recent years, China has introduced a number of policies and funds to support urban domestic sewage treatment. In 2020, China will further promote the treatment of urban domestic sewage from the aspects of planning, financing mechanism, and sewage treatment mechanism, and the daily treatment capacity of urban sewage has reached 192.67 million cubic meters per day, and the sewage treatment rate has reached.

The sewage treatment capacity of the township and county is also improving, and the treatment capacity of the county sewage treatment plant has reached 37.7 million cubic meters per day in 2020, and the treatment rate is .

The use of water treatment agents will continue to expand

The increase in domestic water consumption and the improvement of sewage treatment capacity have made the market scale of water treatment agents in China's municipal water treatment field continue to increase from 2016 to 2019, reaching 11.3 billion yuan in 2019. In 2020, due to the decline in domestic water consumption and the impact of the new crown epidemic, it dropped to 10.4 billion yuan. In the future, with the acceleration of urbanization, the increasing shortage of water resources and the increasingly serious environmental pollution, the market scale of water treatment agents in the field of municipal water treatment will continue to expand.

To sum up, in recent years, China's urbanization rate has increased, domestic water consumption has increased as a whole, the importance of domestic sewage treatment has gradually increased, and the sewage treatment capacity of sewage treatment plants has also been continuously improved, making the market share of water treatment agents in the field of municipal water treatment as a whole expanding. Although the impact of the epidemic will decline slightly in 2020, the market share of water treatment agents in the municipal water treatment field will continue to rise in the future with the further expansion of demand.

The above data refers to the Prospective Industry Research Institute"Analysis Report on the Prospect of China's Water Treatment Agent Industry and Investment Strategic Planning".

It should be ok. At present, the state has strict requirements for environmental pollution, and every new factory will require water treatment equipment. will need water treatment chemicals.

Now there are many manufacturers in the pharmaceutical industry, and their market share is growing every year, and if you have someone from the Environmental Protection Bureau, or have a good relationship with the person in charge of the company, it is very profitable.

Sewage treatment in pharmaceutical factories refers to the treatment of wastewater generated in the production process of pharmaceutical factories to ensure that wastewater discharge meets environmental regulations and standards and reduce environmental pollution.

Wastewater from pharmaceutical manufacturing processes often contains a variety of organic matter, inorganic salts, pharmaceutical residues, heavy metals, and other contaminants. If this wastewater is discharged directly into the natural environment, it can have a serious impact on the water body, soil and ecological environment.

The sewage treatment of pharmaceutical factories mainly includes the following steps:

1.Primary treatment: includes physical treatment methods such as grid filtration or sedimentation for the removal of floating, suspended and large particulate matter from wastewater.

2.Biochemical treatment: Through biological treatment units, such as activated sludge method, aeration bioreactor, etc., Lugao uses the activity of microorganisms and the action of enzymes to decompose, oxidize and transform the organic matter in the wastewater, and degrade it into lower organic matter, carbon dioxide and water.

3.Advanced treatment: Advanced treatment may be required for special contaminants in pharmaceutical wastewater, such as drug residues and heavy metals. Commonly used methods include chemical oxidation, advanced oxidation, adsorption, ion exchange, etc., to degrade or remove these contaminants.

4.Thickening and solidification: For treated sludge or dissolved matter, further thickening and solidification may be required to reduce volume and facilitate disposal.

5.Monitoring and discharge: Monitor the treated wastewater to ensure that the water quality indicators meet the discharge standards, and then discharge the wastewater that meets the requirements safely.

Through this treatment, the wastewater treatment of pharmaceutical factories can effectively reduce the content of harmful substances in wastewater and protect the environment and water resources. At the same time, compliant wastewater treatment is also one of the important requirements for pharmaceutical companies to obtain environmental licenses and continue operations.
