" Although the epidemic is serious, they still try their best in the difficult situation."
Waste water disposal
It can effectively filter and separate the oily sewage generated during the business day, intercept the grease, and then pass it to the underground, about 6 meters x 2. In the 5-meter large oil storage tank, waste oil is extracted every week for subsequent recycling, and then the sewage that meets the discharge standards is discharged. Ningxia Night Market is also the only night market in Taipei City that has installed sewage sewer takeover. In 2018, the Taichung City Water Conservancy Bureau also launched the first "Night Market Grease Retention" program in Taichung's Fengjia business district. The grease retention facility was used to collect the sewage discharged by the stalls, and the oil and water were separated for recycling.
Tail damage caused by sewage discharge
Whether the night market sellers are cooking or cleaning tableware, if the sewage is not carefully cleaned and flows into the ditch, it will pollute the water source, and cause small strongmen, mice, etc. In addition, the water will flow back to the sea to pollute the water quality. The Soil and Water Conservation Office is responsible for promoting the installation of oil-water separation tanks in the centralized cleaning area of the night market, or improving the sewage discharge problem by means of grease traps and sewage sewer pipes. However, the cost of sewage treatment equipment is relatively high, and the equipment and difficulty installed in each night market case are also different.
Introducing the Grease Trap
Whether it is cooking or washing, the night market vendors are all in the same size booth. If the sewage and waste oil are not treated, they will directly flow into the underground waterway. In addition, the water flow will eventually return to nature, which will also affect the water quality of the river. Sewage management is relatively easy to manage in buildings with complete equipment, but it is quite difficult in the field of mobile stalls. Since the sewage problem has not been eradicated, the configuration of oil intercepting tank facilities is very important. Ningxia Night Market completed the "grease trap" in 2012, which is installed under the pavement of each street vendor.
