Jining coal mine domestic sewage treatment equipment has good treatment effect

Introduction to Mine Life Processing Equipment

In recent years, with the continuous development of the economy and the continuous growth of the population, especially in today's rapidly developing economy in China, while creating benefits, various types of pollution have also been created, and there is a growing trend. After suffering from the pain caused by environmental pollution, people gradually realize the importance of the environment and pay more and more attention to environmental protection. Based on the summary of the operating experience of domestic and foreign domestic sewage treatment equipment, combined with our company's scientific research achievements and engineering practice, we have designed a treatment systemMine domestic sewageofMine domestic sewage treatment equipmentOur company adopts the above biological treatment process, which has the advantages of stable and reliable technical performance, good treatment effect, low investment, small land occupation, and convenient maintenance.

Jining coal mine domestic sewage treatment equipment has good treatment effectWeifang Qianqiu Environmental Technology Co., Ltd*Committed to environmental business areas such as mine domestic sewage treatment, exhaust gas treatment, odor control, and environmental accessories and consumables, we aim to create numerous demonstration projects with high technological content, excellent quality, and outstanding effects.

Mine domestic sewage treatment equipmentThe design is mainly aimed atdomestic sewageThe treatment of industrial organic wastewater similar to it. The main processing method is to use the currently mature biochemical treatment technology——Contact oxidation method, water quality parameters are based on general domestic water quality, inlet waterCOD<400mg/lOut of the waterCOD<60mg/lWater ingressBOD 20Omg/lOut of the waterBOD 20mg/lThe indicator design consists of six parts in total:(1)Primary sedimentation tank;(2)Contact oxidation tank;(3)Secondary sedimentation tank;(4)Disinfection pool and disinfection device;(5)Sludge tank;(6)Fan room, fans;
　　 The following are discussed separately:
　　(1)Primary sedimentation tank: The equipment's primary sedimentation tank is a vertical flow sedimentation tank, and the upward flow velocity of sewage in the sedimentation tank is0.6-0.7 millimeters/In seconds, the settled sludge is lifted to the sludge tank by air.
　　(2)Contact oxidation tank: After initial sedimentation, the water flows automatically to the contact tank for biochemical treatment. The contact tank is divided into two stages, with a total residence time of 1More than hours. Enhanced equipment can achieve contact oxidation time up to6Hour by hour, the filler is an efficient biological filler. Easy to form conjunctiva and not clog. The specific surface area of the filler is160m2/m3The gas water ratio of the contact pool is12:1左右。
　　(3)Secondary sedimentation tank: Biochemical wastewater flows into the secondary sedimentation tank, which is a vertical flow sedimentation tank and operates in parallel. The upward flow velocity isO. 3-0.4 millimeters/In seconds. The sludge is discharged by air lifting to the sludge tank.

(4)Disinfection pool and disinfection device: Disinfection pool according to specifications:“ zyhj- 1 ”standard30In minutes, if it is hospital sewage, the disinfection tank can increase the residence time to1-1.5At the hour, solid chlorine tablets are used for contact dissolution disinfection. The disinfection device can continuously change the dosage according to the size of the water output, achieving the goal of adding more water and more medicine, and adding less water and less medicine. Other disinfection devices can be prepared separately. (Note):If used for industrial wastewater disinfection tanks and disinfection devices, it is not necessary
　　(5)Sludge tank: All sludge from the primary and secondary sedimentation tanks is pumped into the sludge tank for concentration. The clear liquid from the sludge tank flows back to the contact oxidation tank for further treatment. After digestion, there is very little residual sludge, generally1-2Clean once a month. The cleaning method can be to use a suction truck to extend from the inspection hole of the sludge tank into the bottom of the sludge and carry out suction and transportation.
　　(6)Fan room, fan:Mine domestic sewage treatment equipmentThe equipment used in the system, including the reflux pump, Roots blower, and disinfection dosing device, are uniformly placed in the equipment room, fan room, and fan operating life30000About an hour.

Basic working principle of mine domestic sewage treatment equipment

Mine domestic sewage treatment equipmentThe design is mainly aimed atdomestic sewageThe treatment of industrial organic wastewater similar to it. The main processing method is to use the currently mature biochemical treatment technology——Contact oxidation method, biological contact oxidation process is a sewage treatment process that falls between activated sludge method and biofilm method. The pool is equipped with packing materials, and some microorganisms are fixed on the surface of the packing materials in the form of biofilms, while others grow in a flocculent suspension in the water. Therefore, it has the characteristics of both activated sludge process and biological filter. The aeration system can adopt a blast or jet aeration system (considering investment and operating costs during design). It is effective to divide the contact oxidation tank into two compartments for cultivating different advantageous strains of microorganisms. *The effective hydraulic retention time is2.5Hour, organic load is1.15kgBOD5/m3.dThe effective hydraulic retention time in the second grid is1.5Hour, organic load0.768kgBOD5/m3.d.

Scope of application of mine domestic sewage treatment equipment

Suitable for residential areas, restaurants, hotels, nursing homes, schools, mines, factories, etcdomestic sewageTreatment and similar industrial wastewater treatment.

Characteristics of Mine Domestic Sewage Treatment Equipment

Can be buried underground
　　 Fully automatic control, no personnel management required
　　 Easy to operate and maintain
　　 Low noise, no odor
　　Long service life

Energy saving mode:
Water saving, rinse with a small amount of clean water when shutting down, no rinsing is required when starting up, and no cooling water is needed.
Secondly, power saving. Our company has independently developed a power saving system, which belongs to the company's core technical secrets. Under the same conditions, the power saving rate can reach 15% -20%.

Balance - Strict balance testing. Our company is equipped with a hard branch dynamic balancing machine and a whole machine dynamic balancing machine, which conduct three or more dynamic balance tests on the screw feeder, drum, and whole machine to ensure equipment balance and product quality.
High temperature resistance - materials: carbon steel and stainless steel. Stainless steel refers to the use of stainless steel for the screw feeder, rotary drum, outer casing, feeding pipe, and drainage slag pipe. The chassis is made of carbon steel; Carbon steel refers to the entire machine being made of carbon steel.

Wear resistant - spiral blade welded with tungsten carbide steel sheet to resist wear and maintain dynamic balance stability; The inner wall of the straight drum is equipped with transverse stainless steel wear-resistant strips, effectively preventing wear and tear on the inner wall of the drum; The slag outlet of the cylinder adopts replaceable ceramic lining.
