The production of diallylamine is usually done by cyanidation or hydrogenation. Cyanidation involves the reaction of acrylonitrile and ammonia in the presence of a catalyst to obtain diallylamine. Hydrogenation involves the reaction of propylene and ammonia in the presence of a catalyst to obtain diallylamine.

Treatment of sewage sludge can include a combination of thickening, digestion and dewatering processes. Thickening is usually the first step in sludge treatment, and sludge digestion is a biological process that breaks down organic solids into stable substances.

Efficient organic sludge dehydrating agent is a chemical substance that can quickly separate water from organic sludge. Common organic sludge dehydrating agents mainly include polymer, inorganic compound and organic substances.

Anti fouling flocculants play an important role in the solid liquid separation of water and wastewater treatment processes. Taking water treatment as an example: flocculation can effectively remove 80% to 95% of suspended substances and 65% to 95% of colloidal substances.

Aqueous ink production wastewater is a weakly alkaline, high concentration, high chroma, and difficult to biodegradable industrial wastewater. The main treatment methods include: chemical oxidation coagulation process, ultrafiltration technology, coagulation air floatation contact oxidation combined process, and so on.

The sewage from the bathhouse is a high-quality reclaimed water source with a large amount of water, low pollution level, and convenient for recycling. In order to better utilize water resources and based on geographical environment considerations, bathing wastewater can be treated by simple and economical methods as greening water.

How to decolorize wastewater? There are mainly the following methods: Decolorization flocculant method, Activated carbon adsorption method, Ozone oxidation decolorization method.

Industrial pollution sources of water environment refer to production equipment or production sites that have harmful effects on the environment in the process of industrial production and have the following characteristics

With the improvement of people's living standards, domestic sewage discharge is becoming more and more serious. In this form, the domestic sewage treatment process is also improving. Now let's learn about the domestic sewage treatment process.

The sludge produced by sewage treatment can be divided into organic sludge and inorganic sludge. Organic sludge is mainly composed of organic substances and is the product of organic wastewater treatment.

Clarifier is a device for water coagulation and removal of suspended solids and colloids in water. The medium used to intercept and separate impurity particles in the clarifier is suspended sludge.

The separation of clean water and sewage is mainly to separate high-polluted water from non-polluted water or low-polluted water and treat them according to their quality to reduce the amount of discharged pollutants and reduce the cost of water treatment.

The new process coal-bearing wastewater treatment system is mainly composed of three parts, including wastewater purification part, sludge treatment part and make-up water part. In this new treatment system, coal-bearing wastewater is mainly treated in a workshop, which includes all functions such as water collection, sedimentation, regulation and supply.

First of all, it is an inevitable requirement to achieve sustainable development. In the 21st century, human society pays more attention to the quality of life and advocates a sustainable long-term development model.

First of all, it is easy to cause blockage in the water conveyance system. In most power plants, coal-bearing wastewater is mainly collected in the sump between the coal bunkers.

As a water treatment agent, PDMDAAC is involved in almost all fields of industrial wastewater, domestic sewage and drinking water treatment; it is used as a clay stabilizer, mud treatment agent, and oily wastewater treatment agent in the oil mining industry; in the daily chemical industry as an antistatic agent, Moisturizers, emollients, etc.

Organic pollution of water bodies: mainly refers to the pollution caused by the discharge of wastewater containing a large amount of organic matter from urban sewage, food industry and paper industry. Inorganic pollution of water bodies: refers to acids, alkalis and inorganic.

Chemical oxygen demand (COD) refers to the oxygen content required by organisms in a certain volume of water, and ammonia nitrogen (NH3-N) refers to the nitrogen in the water in the form of free ammonia (NH3) and ammonium ions (NH4).

The treatment of oily wastewater should first use the oil separator to recover floating oil or heavy oil. The treatment efficiency is 60%-80%, and the oil content in the effluent is about 100-200 mg/L. Emulsified oil and dispersed oil in wastewater are difficult to handle, and emulsification should be prevented or reduced.

The primary treatment of sewage is the physical treatment of sewage, which is the first stage in the sewage treatment level. Secondary treatment of sewage is the purification process of colloidal and dissolved organic matter in sewage after primary treatment of sewage, and biological method and flocculation method are commonly used.
