Tableware cleaning and disinfecting sewage treatment equipment
Tableware cleaning and disinfection wastewater treatment equipment process description:
The design of WSZ-A equipment is mainly aimed at the treatment of domestic sewage and similar industrial organic sewage. 水BOD 20Omg/l，出水BOD 20mg/l指标设计，总共有六部份组成：(1)初沉池；(2)接触氧化池；(3)二沉池；(4)消毒池、消毒装置；(5)污泥池；(6)风机房、风机。 The main treatment method of sewage treatment equipment is to adopt a more mature biochemical treatment technology-contact oxidation method. The water quality parameters are designed according to the general domestic water quality, the inlet BOD 20Omg / l, and the outlet BOD 20mg / l indicators. There are a total of six parts: (1) primary sedimentation tank; (2) contact oxidation tank; (3) secondary sedimentation tank; (4) disinfection tank and disinfection device; (5) sludge tank; (6) fan room and fan.
In a beam-type sedimentation tank, the rising velocity of sewage in the sedimentation tank is 0.6-0.7 mm / sec. The sedimented sludge is lifted to the sludge tank by air. (Note: WSZ-A O.5-5m / h does not have an initial sink)
Roots blowers can automatically alternate. The operating life of a single fan is about 30,000 hours.
Tableware cleaning and disinfection sewage treatment equipment MBR overview:
到直接使用的稳定中水。又可在生物池内维持高浓度的微生物量，工艺剩余污泥少，极有效地去除氨氮，出水悬浮物和浊度接近于零，出水中细菌和病毒被大幅度去除，能耗低，占地面积小 。70年代在美国、日本、南非和欧洲许多国家就已开始将膜生物反应器用于污水和废水处理的研究工作。其水源取自生活污水（如淋浴排水、盥洗排水、洗衣排水、厨房排水、厕所排水等〕 和冷却水。 Sewage treatment equipment adopts membrane bioreactor (Membrane Bioreactor, MBR) technology, which is a new process combining biological treatment technology and membrane separation technology. It replaces the secondary sedimentation tank in the traditional process and can efficiently perform solid-liquid separation. To obtain directly used stable reclaimed water. It can also maintain a high concentration of microorganisms in the biological pond, and the process has less residual sludge, which can effectively remove ammonia nitrogen, and the effluent suspension and turbidity are close to zero. Large-scale removal, low energy consumption, and small footprint . In the 1970s, research work on the use of membrane bioreactors in sewage and wastewater treatment began in the United States, Japan, South Africa, and many countries in Europe. Its water source is derived from domestic sewage (such as Shower drainage, toilet drainage, laundry drainage, kitchen drainage, toilet drainage, etc.] and cooling water.
Process flow of tableware cleaning and disinfection sewage treatment equipment:
Raw water → grille → adjustment tank → lift pump → bioreactor → circulation pump → membrane module → disinfection device → reclaimed water tank → reclaimed water system.
Scope of tableware cleaning and disinfection sewage treatment equipment:
Suitable for residential sewage, office buildings, shopping malls, hotels, restaurants, institutions, schools, factories and other domestic sewage and similar industrial organic wastewater, such as organic sewage treatment in textile, beer, paper, tanning, food, chemical and other industries .
