product description

RXHB-NF decentralized domestic sewage treatment process-biochemical tank adopts biological contact oxidation method, its volume load of filler is relatively low, microorganisms are at the stage of self-oxidation, the amount of sludge is small, and the sludge cycle is long.

Characteristics of decentralized domestic sewage treatment equipment This equipment can treat comprehensive wastewater from domestic systems and similar organic sewage. The two-stage biological contact oxidation treatment process adopts the contact oxidation process, and its treatment effect is better than that of the fully mixed type or the two-stage series fully mixed biological contact oxidation tank. It is smaller in volume than activated sludge, has good adaptability to water quality, good impact load resistance, stable effluent water quality, and does not cause sludge swelling. A new type of elastic three-dimensional filler is used in the pool. The specific surface area is large, and the microorganisms are easy to hang and remove the film. Under the same organic load condition, the removal rate of organic matter is high, and the solubility of oxygen in water can be improved.


I. Water quality analysis:

Domestic sewage in the new countryside is mainly discharged water from various kitchen water, washing water and toilet water used in human life, mostly non-toxic inorganic salts. 污水 ,是水体的主要污染源之一。 Sewage generated during human life is one of the main sources of pollution in water bodies. 粪便和洗涤污水 Mainly feces and washing sewage . 可生化性好,N、P浓度较高,含病原体,总体污染物浓度不是很高,COD、BOD等达标容易。 Its characteristics are good biodegradability, high N and P concentrations, pathogens, overall pollutant concentrations are not very high, and COD, BOD and other standards are easy to meet.

Second, process selection:

格栅+ A/ O /O生物接触氧化+ 消毒设备 工艺,该处理工艺较为成熟,操作运行方便,日常费用低廉,出水稳定,主要设备为钢结构,考虑到周边环境和卫生问题,故该污水处理工程决定采用全埋地式结构,上部覆土,种植花木、草坪,进一步美化环境。 According to the characteristics of the specific sewage water quality of this project, this plan intends to use the conventional " grid + A / O / O biological contact oxidation + disinfection equipment " process. The treatment process is relatively mature, convenient operation and operation, low daily costs, and stable effluent. The main equipment is a steel structure. Considering the surrounding environment and sanitation issues, the sewage treatment project decided to use a fully buried structure, with the upper part covered with soil, planting flowers and lawns, and further beautifying the environment.

Third, the process:

Fourth, process characteristics:

(1) The technological process is mature, with few structures, flexible operation and convenient management.
(2) The province has a low investment in infrastructure and low operating costs.
(3) The treatment effect is stable, and the quality of the effluent water is good, which can realize decarbonization, nitrogen and phosphorus removal.
(4) The amount of sludge is small, the sludge properties are stable, and the sludge treatment cost is low.
(5) Can withstand the impact of water volume and water quality.
(6) The sewage treatment system has high automation and convenient management.
