Problems solved by technology

[0003] Rural domestic sewage is very scattered, it is difficult to collect sewage, there is basically no sewage treatment equipment, the concentration of domestic sewage is low, and the range of variation is relatively large. There may even be a phenomenon of cut-off, so special treatment equipment is required for these characteristics of rural sewage

Embodiment 1

[0036] Taking domestic sewage in a rural area of ​​Tianjin as an example, the villager discharges 150 tons of domestic sewage per day. Three sewage treatment devices are installed in the village, with an average treatment capacity of 50 tons per day for each treatment device. Now, one of them is used for processing The water quality is relatively stable and the water quantity is sufficient as an example for illustration.

[0037] Continuously monitor the incoming water of the village, the COD content is between 100-200mg / L, the BOD content is between 50-100mg / L, the total nitrogen content is between 15-30mg / L, and the ammonia nitrogen is between 17-40mg / L. The total phosphorus is between 1-5mg / L, and the pH is between 7.2-8.4. After calculation, the BOD / COD ratio of the water quality is about 0.5, and the biodegradability is good, indicating that biological methods can be used to remove organic matter. The ratio of BOD / TN is about 0.33, and the carbon source is basically suffi...

Abstract

The invention discloses buried sewage processing equipment, which mainly comprises a control box, an equipment room, an anaerobic tank, an anoxic tank, an aerobic tank, and an ultrafiltration membranetank; all operation rooms are communicated with each other; the bottom end of the equipment is provided with a water inlet; and the top end of the equipment is provided with a water outlet. Sewage isintroduced into the equipment from the bottom end, sequentially goes through the anaerobic tank, the anoxic tank, and the aerobic tank, and finally is discharged from the water outlet after going through the ultrafiltration membrane tank. The energy consumption of the equipment is largely reduced; due to a novel ultrafiltration membrane, the occupied area is largely reduced, the sewage processingeffect is good, and the gas utilization rate is high. Sewage is decomposed in each operation room, and the effluent reaches the discharge standards.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to an underground sewage treatment equipment. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of rural living standards, people's awareness of environmental protection is becoming stronger and stronger. The 19th National Congress of the Communist Party of China proposed the strategy of rural revitalization to create ecologically livable villages, and the treatment of domestic sewage in rural areas has been put on top of the list schedule. According to relevant statistics, 9 billion tons of domestic sewage are generated in rural areas of the country every day, and most of these sewage are directly discharged into nature without relevant treatment, causing great pollution and damage to nature. Living in rural areas, the treatment of rural domestic sewage has important strategic significance. [0...
