Brief description: The design of rural sewage treatment equipment/hospital sewage treatment equipment consists of six parts: regulating pool; Contact oxidation tank; Secondary sedimentation basin; Disinfection device; Sludge treatment machine; Fan, rural sewage treatment equipment/hospital sewage treatment equipment is mainly for the treatment of domestic sewage and similar industrial organic sewage, the main treatment means is to use the current more mature biochemical treatment.

Rural sewage treatment equipment/hospital sewage treatment equipment design is mainly for the treatment of domestic sewage and similar industrial organic sewage, the main treatment means is to use the current more mature biochemical treatment technology - contact oxidation method, water quality parameters according to the general quality of life, influent-BOD200mg /1, effluent BOD200mg/1 index design.

There are six parts in total: the regulating pool; Contact oxidation tank; Secondary sedimentation basin; Disinfection device; Sludge treatment machine; Fan,

The following is a detailed description of each unit of our domestic sewage treatment equipment:

1. Primary sedimentation tank: The primary sedimentation tank is a vertical sedimentation tank, and the rising flow rate of sewage in the brooding tank is 0.6-0.7mm/s, so that large granular sludge can settle down, reduce the load of subsequent biochemical treatment, and the precipitated sludge can be raised to the regulating tank through the sludge pipeline to achieve a second cycle of treatment; 

2. contact oxidation pool: after the initial settlement of water flow to the contact pool for biochemical treatment, the contact pool is divided into three levels, the total residence time is more than 1 hour, of which the enhanced equipment contact oxidation time can reach 6 hours, the filler is a novel filler, easy conjunctival, no blockage. The specific surface area of the filler is 160m2/m3, and the gas-water ratio of the contact pool is about 12:1;

3. Secondary sedimentation tank: The biochemical sewage flows to the secondary sedimentation tank, which is two vertical sedimentation tanks, and they run in parallel. The rising flow rate is 0.3-0.4 mm/s. Sludge discharge adopts air lifting to sludge unit;

4. Disinfection tank device: disinfection tank according to the specification: "TJ14-74" standard for 30 minutes, if the hospital sewage, disinfection tank can increase the residence time to 1-1.5 hours, using solid chlorine tablets contact dissolving disinfection method. The disinfection device can continuously change the dosage according to the size of the water output, so as to achieve the purpose of more water and more medicine, less water and less medicine. Other disinfection devices can be prepared separately;

5. Sludge device: sludge tank clear liquid back to the heat exchange oxidation tank for reprocessing, after digestion of the remaining sludge is very little, generally 1-2 years to clean once, cleaning method using suction truck from the sludge tank inspection hole into the bottom of the sludge, suction can be carried out. You can also recycle it;

6. The fan: the fan is located above the disinfection, the inlet adopts double-layer sound insulation, the inlet has a muffler and the fan filter, so there is no noise during operation; The operation life of a single fan is about 30,000 hours.
