Graft technology of reverse osmosis scale inhibitor

Graft technology of reverse osmosis scale inhibitor is to use special chemical reaction to make some functional
groups on the high molecular weight chain react with other compounds, so as to introduce a certain molecular
weight or branch chain with special functional groups into the molecule, increase the molecular weight or locally
change the molecular structure, so as to enhance the molecular scale inhibitor. , for example, the C3 ~ C20
dibasic acid and anhydride or dicarboxylic esters (such as maleic anhydride or its polymer) and ethylene
polyamine (at least more than 2 C and 2 ~ 5 amino) polycondensation reaction, and then under the alkali
catalytic reaction with ethylene oxide epoxy propane and butane epoxy, N some or all of the alkylation, and
get the molecular structure of reverse osmosis scale inhibitor is like in the original condensation on the product
molecular co ected with polyethylene oxide branched chain.

Weihai domestic sewage treatment project selection skills

The water collection shall be able to ensure the balance of water inflow, so as to maintain the normal water level of the air flotation pool. Therefore, to ensure the flocculation treatment effect of papermaking wastewater treatment equipment, we can choose the correct flocculant model according to the nature of wastewater, and achieve better flocculation effect with the correct dissolution ratio, dosage and dissolution time. Among these materials, stainless steel is the best one for compression resistance and corrosion resistance. It is easy to complete automatic control, simple to manage and operate; the equipment can be connected with the car and made into a mobile integrated sewage treatment equipment; this is a commonly used pretreatment method. When the pipeline system of sewage treatment equipment leaks or breaks, the operation of sewage treatment equipment shall be stopped immediately, and all the leaked sewage shall be collected and discharged to the regulating pool for reprocessing, and the maintenance personnel shall be informed at the time. Buried sewage treatment equipment delivery site buried sewage treatment equipment delivery site buried sewage treatment equipment characteristics: the equipment can be fully buried, half buried, or placed above the ground surface, can not be arranged in a standardized way, and set according to the terrain. Laundry sewage, animal husbandry sewage, hair salon sewage, etc.

Strengthen long-term management of rural sewage treatment facilities

1、 Establish a process specification that is easy to manage. Japan’s experience in the treatment of rural domestic sewage is very worthy of our study and reference. Since the 1960s, they have developed the Johkasou technology, which is an integrated treatment facility technology applied in rural decentralized sewage treatment. For more than half a century, with the continuous improvement of the drainage index, the purification tank technology is also improving step by step, which plays an irreplaceable role in the protection of rural water environment in Japan. As far as I know, the municipal level platform for operation and maintenance of rural domestic sewage treatment and the supervision platform system of eight districts and counties (cities) including Xihu District and Yuhang District have been completed. It is suggested that the intelligent function of the supervision platform should be further improved during the bid raising and transformation, and the data mining and sharing of rural domestic sewage treatment facilities in the basin should be realized in the spring of the era of “big data”. For example, a more advanced integrated sewage treatment system (similar to a purification tank) can be piloted to deal with point source pollution, and big data intelligent management can be applied to achieve effluent quality standards. It can also use Hangzhou’s leading Internet of things technology to develop artificial intelligence prediction and artificial emergency management functions.

2、 Establish a standardized regulatory system. The responsibility of the management department should be shifted to supervision, guidance, standardization and other aspects, such as the introduction of benchmarking management and the establishment of operation and maintenance benchmarking. The first is to clarify the qualification of the third party; the second is to discuss the evaluation indicators with the third party; the third is to establish the third party operation and maintenance benchmark.

Significance of Weihai buried sewage treatment equipment engineering construction

The integrated sewage treatment equipment uses membrane bioreactor (MBR) for sewage treatment and reuse. It has all the advantages of membrane bioreactor: good water quality, low operation cost, strong system impact resistance, less sludge, high degree of automation. In addition, as an integrated equipment, it has a small floor area and is easy to integrate. As an effective supplement to the traditional sewage treatment plant, the system has been widely used in urban residential communities, hotels, tourist attractions, rural communities and other fields. How to deal with the pipe blockage of buried domestic sewage treatment equipment how to deal with the pipe blockage of buried domestic sewage treatment equipment how to deal with the buried domestic sewage treatment equipment is now one of the necessary equipment for the environmental protection profession, which shows that its advantages have been recognized by the market, but since it is a sewage treatment equipment, it must deal with sewage, and the situation of pipe blockage may be prevented. Generally speaking, the consumption of domestic sewage is 2-3 grams per ton of sewage and 8 grams of hospital sewage. Pay attention to the connection and plane layout of equipment and pipeline connection. According to the specification requirements, it can be arranged arbitrarily according to the user’s requirements. The working principle is in class A, because the concentration of organic matter in sewage is very high, the microorganism is in the state of anoxia, at this time, the microorganism is facultative microorganism, so class a tank not only has certain organic matter removal function, reduces the organic load of subsequent aerobic tank, the concentration of organic matter decreases, but also has a certain amount of organic matter and higher NH3-N. The function and principle of aerobic tank anaerobic tank in sewage treatment the function of aerobic tank is to make the activated sludge breathe aerobically, further decompose the organic matter into inorganic matter, and remove the pollutants in sewage. The disinfectant should be carried out in the disinfection tank according to the buried integrated sewage treatment equipment. The water from the secondary sedimentation tank passes through the disinfectant tank, and the disinfectant is partially dissolved, so as to achieve the disinfection effect.
