Brief introduction of the equipment of the integrated sewage lifting device

Air flotation machine is a water treatment equipment that produces a large number of fine bubbles in the water by the dissolved air system, so that the air is attached to the suspended matter particles in the form of highly dispersed tiny bubbles, resulting in a state with a density less than that of water, and uses the principle of buoyancy to make it float on the water surface, so as to realize the solid-liquid separation. Air flotation machines are divided into super-efficient shallow air flotation machines, vortex concave air flotation machines, and advection air flotation machines. It has applications in water supply, industrial wastewater and municipal sewage treatment.

The advantages of air flotation machine are that its solid-liquid separation equipment has the characteristics of low investment, very small ground occupation, high degree of automation, and convenient operation and management. Click to learn about the super atomized dissolved air flotation machineAir flotation machine is a machine that uses small bubbles or tiny bubbles to make the impurities in the medium surface surface. For some of the specific gravity contained in the water body, which is close to the subtlety of water, and its own weight is difficult to sink or float, the air flotation can be used....

The Integrated Sewage Lift is a highly integrated sewage discharge system. It consists of a sump pump, a sump tank, a pipeline, a valve, a level gauge and an electrical control device. It is to collect the waste water discharged from sewage pipes and sanitation facilities that are below the sewer level or far away from the municipal sewage pipe network through the water collection tank, and lift and pump it to the urban sewage system.

With the prosperity and development of society, the construction of various underground buildings is also increasing, but the supporting sewage lifting facilities are relatively lagging behind, the traditional practice of underground excavation of sewage pools is generally adopted at present, and the problems of odor overflow, mosquitoes and flies and bacteria breeding are inevitable, and the state advocates the construction of an environmentally friendly society is extremely incommensurate.

With the continuous improvement of people's quality of life, all kinds of sewage are constantly increasing, and environmental protection is the constant theme of today's societyWhat are the specific fields where the integrated sewage treatment equipment can be used?

Sewage is generally divided into: industrial sewage, public place sewage, domestic sewage, industrial parks, agricultural sewage, etc., which can be subdivided into various industries.

Industrial sewageSmall- and medium-sized organic wastewater treatment in factories, mines, food factories, printing and dyeing factories, chemical plants, etc.;

Sewage in public places:sewage treatment of tourist spots, scenic spots, highways, stations, airports, railways, ships, seaports and wharves;

Domestic sewage:domestic sewage from schools, residences, towns, hotels, restaurants, hospitals, comprehensive office buildings, etc.;

Agricultural sewage: animal husbandry, aquatic product processing industry, slaughterhouse, aquaculture and other sewage treatment;

The main pollutant sources of general sewage are: raw pollutants, toxic pollutants, petroleum pollutants, inorganic pollutants, oxygen consumption pollutants, etc.

In different places, the water quality treatment requirements and discharge requirements are different, but the specific treatment process of the equipment is also different.

Box, water pump, level switch, control four parts, if you are afraid of blockage, choose the pump with grinding function of the sewage lifter, if the foundation pit is installed is best to choose the waterproof grade of IP68 Libertypumps sewage lifter.

Number of pumps.

Type of integrated wastewater lifting equipment. In terms of the number of pump configurations, it is generally divided into single pump type and double pump type. The single-pump type is relatively low in cost, and there is no backup pump.

It is generally used in small places such as homes. The double pump type has a relatively higher insurance factor because it has a backup pump. It is generally used in large places such as hotels and shopping malls.

Water tank material. The integrated sewage lifting equipment is generally composed of a water collection tank, a water pump, and an electronic control accessory. The material of the water collection tank is made of high-density polyethylene, and there are also stainless steel materials. Polyethylene is more corrosion-resistant and more impact-resistant.

When welding stainless steel, one is heavier and the mechanical noise is relatively large. In addition, there are defects in the weld, and the corrosion resistance is relatively weak. Therefore, in terms of application, stainless steel material is not as widely used as polyethylene material.

The sewage lifting device is composed of a rubber water storage bladder, a crushing and cutting pump, a check valve and the inlet and outlet of sewage. The start and stop of its cutting pump is not based on the liquid level, the sewage lifting device but transmits the change of pressure in the pressure sensing stomata to the pressure sensor, once the sewage enters the water storage bladder, the air in the pressure sensing pore is squeezed, and with the increase of the amount of water in the bag, the pressure also increases, thus driving the start and stop of the cutting pump. When the sewage lifter is placed on the ground at the same elevation as the sanitary appliance, the sewage lifter is suitable for the type where the toilet is drained.

If the toilet used for drainage, the sewage lifter can only be placed in the underground working pit, at this time, we must pay attention to the sealing of the underground working pit, because the connection sealing inside the sewage lifter is very good, but when there is water outside, it will seep into its mechanical and electrical parts and cause failure. This is important to pay attention to when using. Specifically, you can contact Cheng Gong of Hangzhou Guiguan Environmental Protection Technology ****, he is more professional.

Hope this answer is useful to you.

The special equipment for automatic basement sewage discharge is mainly composed of a collection (sewage) tank, a lifting pump, an auxiliary sewage pump, a control cabinet and the corresponding filters, pipelines, valves, etc.

The control cabinet is programmed and controlled, fully automatic operation, no personnel are on duty, and the lifting pump is alternate and rotated for each other. When the equipment fails, the alarm system will be automatically started, the alarm indicator light will flash, and an audible alarm will be issued to remind the personnel on duty. In addition, there is a manual operating system on the control cabinet, which can manually start and stop the pump in an emergency on site.

In addition to the two-pump configuration, the equipment is available in single and four-pump configurations.

The second-stage biological contact oxidation treatment process adopts push-flow biological contact oxidation, and its treatment effect is better than that of fully mixed or two-stage series fully mixed biological contact oxidation tank. Weifang Tianyuan Environmental Protection Technology Co., Ltd. is a high-tech enterprise integrating the production and research and development of environmental protection equipment, and is now the cooperation base of Shandong Academy of Water Conservancy Sciences, and was designated as a key recommended enterprise by Shandong Provincial Environmental Protection Bureau in 2011.
