Well septic tank:
Well septic tank is a traditional way to store feces, usually made of concrete or brick, which is used to store feces and urine produced by rural toilets. However, the pit septic tank has a small water storage capacity, and sludge is easy to deposit at the bottom of the well, which reduces the treatment efficiency and has odor and hygiene problems.
Septic tank:
Septic tank is an advanced rural toilet treatment equipment, which is used to treat feces, urine and wastewater. It has the functions of storage, separation, decomposition and disinfection, so that the treated waste water can get qualified chemical fertilizer and purified water. However, septic tanks need regular cleaning and maintenance, and there are also some sewage problems.
Biogas pit:
Biogas pit is an efficient and energy-saving rural toilet treatment equipment, which can decompose organic wastes such as feces and urine into biogas and biogas residue. Biogas can be used for stoves and power generation, and biogas residue can be used as farmland fertilizer. However, biogas digesters also need regular cleaning and fixed maintenance, and there are also some safety problems such as odor and explosion.
Sewage treatment equipment:
Sewage treatment equipment is a relatively new type of rural toilet treatment equipment, which can efficiently treat wastewater into high-quality fertilizer and clean water, and also has the functions of reducing pollution discharge and saving water resources. However, sewage treatment equipment needs to invest a lot of money and energy, and also needs professional operation and maintenance.
In a word, the construction of rural toilet sewage treatment equipment in Chengdu is of great significance to rural environmental sanitation management and resource utilization. Appropriate treatment methods and equipment should be selected according to the actual situation and needs, and publicity, education and technical support for farmers should be strengthened.
