Hotel sewage characteristics

Hotel indoor sewage discharge is waste, sewage, rain and water flow system, hotel sewage mainly comes from room sewage, restaurant wastewater, oily wastewater (garage, equipment room). Domestic sewage mainly includes room flushing and washing, showering and other sewage, kitchen and garage oily sewage, etc., in addition to solid pollutants, aerobic pollutants, and nutrient pollutants (N, P).

 

Wastewater treatment process

The pretreatment of wastewater and waste water treatment process firstly removes impurities such as bones, leaves and even washing cloth from the food waste water directly recycled from restaurants and restaurants, as well as starch, protein, sugar and detergent. And impurities such as colloidal substances. The liquid portion is then subjected to oil-water separation. For the oily portion to be acid-extracted and washed with water, a waste oil is obtained, wherein the acid addition amount in the acid precipitation process is preferably controlled between pH 2-3.

After the water and water are separated, the water is mixed with the water to be washed, and then the water and water are adjusted through the adjustment tank, and then pumped to the coagulation air floatation tank to remove most of the SS, oil and some organic matter, and then biochemical treatment. The biochemical treatment adopts the SBR-PACT method, and the powdered activated carbon is added to the biochemical pool, and the biochemical treatment effluent reaches the standard discharge; the sludge is dewatered after being put into the sludge concentration tank.

In this process, the treatment of the wastewater is inoculated with the molasses by the pretreatment system and the biochemical treatment of the kitchen waste liquid culture agent.

Catering Sewage—◆ Hotel, hotel grease trap or plastic bucket collection concentrated—◆ Rotating machinery grille——Intelligent oil-water separation system—◆ Combination pool—◆ Acid precipitation—◆ Washing—◆泔水油—Comprehensive use of sludge concentration tank— ◆ Plate and frame filter press - ◆ a small amount of dry mud

 

Catering and catering wastewater treatment and wastewater treatment process

Pretreatment system: The regulating tank and the coagulation flotation tank mainly stabilize the water quality and quantity, and remove or reduce the organic and inorganic substances in the wastewater that affect the subsequent biochemical treatment. Because the pH value of the wastewater influent water is low, it is acidic wastewater, and the oil content is high. Here, alkali neutralization and a coagulation flotation method are used.
