What is the way to clean up chemical pollution?

Jiangsu Zhongming Environmental Protection Technology Co., Ltd. is an environmental engineering company engaged in industrial waste gas on-site research, technology research and development, process customization, equipment manufacturing, project site construction and installation, operation and maintenance. At present, the company has 8 branches in the country, including four standard production plants, which are located in Suzhou, Langfang, Hebei and Shenyang, with a total production area of more than 42,000 square meters. The company has more than 10 years of experience in environmental protection equipment manufacturing, and now has a scientific quality management system and passed the ISO9001-2008-14001-18040 quality management system and the EU CE certification.

The core products are "catalytic combustion equipment", "photo-oxygen catalytic equipment", RTO, RCO, condensation** and "low-temperature plasma equipment", and the successful implementation of waste gas treatment projects in hundreds of factories has left a good reputation in the field of VOCs waste gas treatment.

Depending on the nature of the pollutant, the treatment method is determined.

The method is specific to the form of the grease in the water, for example, the gravitational flotation method is usually used for free grease. The state of oil in chemical wastewater is complex, including free, polymeric, and emulsified. or react with other impurities in the water to form new compounds. In addition to the above-mentioned gravity separation, there are also a combination of coarse granulation, air flotation after demulsification (i.e., acid demulsification) and various biochemical methods.

Removing grease from wastewater is generally difficult to accomplish by a single method. Oils and fats should be considered for reuse first, rather than by biochemical oxidation. In the past decade, the scientific and technological level of ultrafiltration membranes in China has been rising, and membranes are more and more widely used for the filtration and separation of pollutants and water in wastewater treatment.

For example, the treatment of machining emulsion wastewater can be treated and regenerated with ceramic membranes. Organic membranes are rarely successfully utilized in oily wastewater. In recent years, a large number of experiments have been done to explore the application technology of organic membranes in oily wastewater.

We are mainly ** vertically known! The electroplating chemical industry is serious, and the factory can emit a pungent smell from time to time! According to reliable sources, hydrochloric acid, nitrate is a water!

Ingredients and the like! Everything in the river is destroyed! The heavy metals in the river water are seriously exceeded!

Farmers use this water! Irrigated rice fields come out of rice heavy metals exceed the standard!

Usually their factory can emit a pungent smell from time to time! According to reliable sources, hydrochloric acid, nitrate water! Ingredient land side or something!

All the creatures in the Lihu River have destroyed everything! The river has learned that the heavy metals in the water are seriously exceeded! Farmers use this water!

Irrigated rice fields come out of rice heavy metals exceed the standard! Main chemical pollutants: carbon dioxide, hydrogen sulfide, carbon monoxide, oil pollution, sewage, catalyst heavy metals, waste gas, waste residue, waste oil, etc.!

First of all, don't pollute, pollution and then treatment time-consuming, laborious and costly, the environmental protection effect is not good, to deal with pollution to see what kind of pollution, if it is water, water treatment, if it is chemical waste gas pollution, first gas absorption, and then separation, combustion, if it is chemical raw material pollution, first collect it, and then separate the first treatment, is chemical waste pollution to be collected and classified first.

It mainly depends on what kind of pollutants are, and then different treatment methods can be taken according to different pollutants.

There are three commonly used treatment methods for chemical waste gas:

1. Absorption method;

2. Adsorption method;

3. Incineration: materials with organic pollutants or odors in organic chemical production waste, which can be used for direct combustion or catalytic combustion treatment. It is required that the combustion must be complete, otherwise the intermediate products form contaminants in incineration that may be more dangerous than the original.

In response to China's serious air pollution problem, ten measures have been deployed to prevent and control air pollution, including the proposed revision of the Air Pollution Prevention and Control Law and other laws, strengthening the governance of densely populated areas and key large cities, building a responsibility assessment system for the air environment remediation targets in various provinces (autonomous regions and municipalities), and incorporating heavily polluted weather into the emergency management of local emergencies. The national policy is good, but although there is a national policy, it is not enough, and there must be a strong supervision mechanism to ensure that the implementation does not fall short. Let factories and enterprises comply with relevant regulations, and only discharge the "three wastes" after reaching the standard, so that car owners can drive less or use clean, low-sulfur and low-nitrogen energy, and residents should use desulfurized coal, and no firecrackers will be set off on holidays.

Chemical sewage has always been a major polluter, serious pollution to rivers and air, and has caused serious harm to human health. Therefore, it is difficult to treat chemical wastewater, and it is necessary to choose suitable chemical sewage treatment equipment for treatment.

According to the characteristics of chemical wastewater, there are two types of commonly used treatment methods: chemical method and physical method. The chemical method is to add chemicals to the sewage discharged from the chemical plant to produce a chemical reaction with the pollutants in the sewage to achieve the effect of removing organic and inorganic substances, mainly including chemical coagulation, chemical oxidation, electrochemical oxidation, etc. Physical methods include filtration method, gravity precipitation method, and air flotation method.

At present, most factories choose physicochemical + biochemical to treat chemical wastewater, because the pollutants are soluble such as organic sulfides, phosphides, nitrides, aromatics, halogenated aromatics. Therefore, the removal rate of physicochemical means is low, and a large amount of clean water is needed to dilute to a low concentration (10 to 50 times) before biochemistry, and some compounds are biodegradable, so the biochemical effluent is often not up to standard. And this method equipment is large in size, high in cost, high in operating cost.

The catalytic oxidation technology developed by our company overcomes the shortcomings of the above technologies and greatly improves the efficiency of sewage treatment.

You are wrong, the main cause of air pollution is the combustion of fossil fuels, and the chlorine produced after the use of hydrochloric acid is extremely small, which is generally only available in laboratories, and everyone must be excluded as exhaust gas devices, and chemical plants are more stringent in this regard, and the state has designated standards, and those who fail to meet the standards will be ordered to shut down.

The main source of air pollution is the burning of fossil fuels.

It's too big a problem, too many analogies, about what you produce and what ingredients you use.
