Rural residents in remote areas, constrained by their level of economic development, are generally faced with the problem of a low rate of treatment of rural domestic sewage. At present, the annual discharge of domestic sewage from rural areas is approaching 10 billion tonnes, and the trend is increasing year by year, but the situation with regard to its treatment is worrying. According to statistics, up to 96 per cent of villages lack drainage channels and sewage treatment systems, resulting in the uncontrolled discharge of domestic sewage.
Studies have shown that in remote rural and mountainous areas, complex terrain and long distances to lay pipelines make it difficult to implement centralised sewerage construction. In mountainous areas, the topography, geological conditions and scattered distribution of residents increase the difficulty and cost of constructing sewage treatment facilities, and both decentralised and centralised treatment face high investment costs. In rural areas, the task of environmental management is arduous due to factors such as dispersed settlements, weak economic fundamentals and high population density. Simply copying the urban governance model is difficult to meet the needs of green and sustainable development in rural areas.
In view of the actual situation of China’s vast rural areas, the promotion of small-scale integrated wastewater treatment equipment or will become a universally applicable solution. Our small integrated equipment carefully built, with the following characteristics:
1. Small footprint
Integrated wastewater treatment equipment can be buried in the ground below the surface, so the equipment does not need to cover an area, the surface can be used as green and square land, practical and beautiful.
2.Long service life
Integrated wastewater treatment equipment has a special coating and its own material aging resistance, resistance to scouring, rust. General anti-corrosion equipment life of more than 15 years.
3. Good treatment effect
Integrated wastewater treatment equipment in the AO biological treatment technology, mostly using push-flow biological contact oxidation tank, the treatment effect is better than completely mixed or two or three tandem completely mixed biological contact oxidation tank. At the same time than the activated sludge tank small size, strong adaptability to water quality, good impact resistance, stable effluent water quality, will not produce sludge expansion. At the same time, the biological contact oxidation tank using a new flexible three-dimensional filler, in fact, large surface area, microbial film, easy to remove the film, in the same organic load conditions, than other filler on the removal of organic matter is high, you can improve the oxygen in the air in the water solubility.
4, strong deodorant function.
Integrated wastewater treatment equipment is basically equipped with deodorant function. The upper space of the reinforced concrete structure pool body is used to set up improved soil and air distribution pipes. The components that emit bad odour are deodorized by dissolving the water contained in the soil in the soil layer, adsorbing and having a chemical reaction on the soil surface, and finally decomposing into microorganisms.
5、Easy management
Most of the integrated wastewater treatment equipments are equipped with fully automatic electrical control system and equipment damage alarm system, which makes the equipments reliable, and usually do not need to be managed by the person in charge, but only maintained on a monthly or quarterly basis, or even directly entrusted to be operated by local residents on a regular basis.
LiDing Environmental Protection has been ploughing into the environmental industry for ten years, focusing on the design, research and development, manufacturing and operation of regional decentralised wastewater treatment system equipment. Relying on advanced standardised and modularised automatic production lines, Liding’s products have demonstrated significant advantages in both quality and performance. The company’s self-developed small-scale sewage treatment equipment is specially designed for decentralised farmers, and with its high efficiency, durability and integration, it perfectly suits the needs of rural sewage treatment.
