Problems faced by sewage treatment

Optimization scheme:

Energy crisis and environmental pollution are a hot issue in the world today. The development of economy inevitably consumes energy, and there are problems of waste discharge and pollution. Therefore, how to achieve lower resource consumption and environmental protection under the premise of ensuring sustainable economic development has become an inevitable transition to achieve sustainable global economic development and harmonious coexistence between human and nature today and in the future, and has epoch-making significance. Today, this consensus exists and is incumbent upon "energy managers."

Countries are making every effort to develop environmental cleaning technology in order to reduce energy consumption and curb excessive damage to the environment. In the United States, scientific research institutions pay particular attention to the research and development of environmental protection technology, a large number of high-tech enterprises have launched related new technologies in the past two years, attracting international attention, and China is gradually moving closer to new technologies of environmental protection cleaning agents. Successfully created a set of water system optimization projects that meet the needs of modern industry, hoping to help users solve many practical problems in the face of today's rising energy, high energy consumption, environmental pressure and other background, so as to achieve substantial cost control and competitiveness improvement.

1, the early control - self-cleaning water filter

Application purpose and value: The implementation of control from the source can maximize the good operation of the system and reduce losses. How it works:

The sewage enters the inlet, where it enters the center of the fine mesh, and then the sewage comes out through the fine mesh and into the outlet.

The excess solids gather on the inner surface of the fine mesh to form a filter cake, which filters out even finer particles, creating a pressure difference. Once the pressure drop reaches the preset level, a cleaning cycle is activated by the control system by opening the cleaning valve atmospheric blowdown and closing the optional control outlet valve (C.O.V.).

Therefore, the pressure drop is in the hydraulic engine room and the assembled vacuum cleaner. The pressure drop creates a backwash that absorbs dust on the screen, similar to a vacuum cleaner. The backwash water passes through the nozzle and vacuum cleaner line before being discharged from the hydraulic motor hole.

The water is removed by a hydraulic motor causing the dust collector to rotate, similar to a spray machine. The pressure drop in the hydraulic engine room further forces the dust collector parts to move on an axis controlled by a hydraulic piston, which in combination ensures that the entire screen area is cleaned at each stage.

2, medium-term prevention - electronic descaling instrument

Application purpose and value: Since a large number of calcium and magnesium ions in the water system are difficult to be effectively treated in the early stage, CO2 is precipitated in the subsequent water system under the action of temperature to produce slightly soluble CaCO3 and MgCO3. As the solubility of CaCO3 and MgCO3 decreases with the rise of temperature, they crystallized out of water and continuously deposited on the surface of equipment systems such as heat exchangers, which has a significant impact on energy consumption and continuity. The application of electronic scale remover can effectively control the generation of more than 90% of the scale, so it means that more than 90% of the energy loss is reduced, while ensuring continuous production to the maximum extent.

Working principle: The basic principle of the electronic descaler is to change the physical molecular structure that causes the formation of pipe scale, use magnetic composite ripples to change the surrounding environment conditions to crush the bonds between electric ions, and make them synthesize stable non-pipe scale substances. The principle of Decor's action is different from any previous physical and chemical descaling method, and its core is a modulated signal generator. Using a unique integrated circuit and signal processing technology, a modulation signal of complex frequency is generated, and the modulated signal is added to the pipeline through the signal cable, and a molecular force dynamic interference field (ADDMF signal field) is generated inside the pipeline, which acts on the fluid in the pipeline and the dissolved salt molecules in it, producing a nucleation effect.

3. Deal with it later

Because very few calcium and magnesium ions are not controlled within the scope of the magnetic scale remover, very little scale will accumulate on the surface after a long period; Or, some equipment systems for some reason failed to achieve the use of electronic scaling instrument;

As the equipment prevention stage, the self-cleaning filter can prevent the accumulation of impurities and particles in the heat exchanger, and has a good removal effect on the substances that can be seen by the naked eye. It can filter out algae, sand, silt, rust sheets, pipe scale and other debris contained in the raw water, thus effectively preventing the generation of scale crystal nuclei. Protects downstream equipment such as heat exchangers, nozzles, instruments, pump seals, air compressors, I.E. Safe and continuous operation of R.O. equipment, etc.;
