What is the standard for the construction of modern supporting facilities in smart farmers' markets?

Supporting engineering facilities include drainage and sewage system, lighting design and ventilation system planning of the market. Next, let's look at it together.

The ground and sewer in the market should be reasonably designed and have good sewage discharge performance. Water supply and drainage facilities shall meet the following requirements in addition to building water supply and drainage design standards:

1. stalls engaged in aquatic products, cooked food and meat shall supply water to the stalls, and the water supply shall be measured separately. The vegetable market should be equipped with a faucet for washing the floor.

2. Sewage pipes (ditches) in the market should be set up separately, forming a system of their own, and should not be shared with the sewage pipes of the building itself. In order to ensure the smooth flow of sewage pipes in the market and facilitate cleaning and dredging, the diameter of sewage pipes should not be less than 300mm, the spacing of inspection wells should not be greater than 10m, and the spacing of inspection wells should not be greater than 10m.

3. An open ditch shall be set in front of the aquatic product booth, with a section size of not less than 0.3× 0.3m and covered with a cover plate. Open ditches or floor drains should be set in front of other stalls to facilitate sewage discharge, and rat net covers should be set at the entrance of sewage. The market drainage ditch should be made of stainless steel, PVC plastic, ceramic tile and other materials with good antifouling and self-cleaning, with a width of not less than 20cm and an arc bottom depth of not less than 15cm. Water seal should be set at the joint of buried drainage pipe and open ditch to prevent odor from overflowing. The sewage discharged from the salted cooked food processing stall should be provided with a grease trap, which can only enter the sewer after degreasing treatment.

4. The drainage system should be treated by septic tank (three-stage filtration treatment facility) according to the requirements of environmental protection before being discharged into the municipal sewage pipe network. Sewage discharged from aquatic products, chilled and poultry business areas (stalls) should be equipped with a first-class slag separation filtration facility before being discharged into septic tanks (three-level filtration treatment facilities).

The vegetable market should be naturally lit and equipped with corresponding lighting facilities. In addition to meeting the requirements of building electrical design standards, electrical equipment shall also meet the following requirements:

1. The lighting of the market trading hall shall comply with the relevant technical specifications. The market capacity is configured according to the standard of 20-40W/m2. Lighting adopts high-efficiency lamps and energy-saving light sources. Fluorescent lamps should use electronic ballasts or energy-saving inductive ballasts.

2. Sockets shall be splash-proof sockets, with no less than 1 for each booth and no less than 2 stalls for aquatic products and fresh meat. In principle, the installation height of sockets shall not be less than 1.5m: at least 1 lighting lamp shall be installed in front of each stall for aquatic products and fresh meat.

3 cooked food, poultry frozen products and other business premises lighting lamps, sockets, should be installed and designed according to the different needs of business households.

4. Electrical pipelines in the market should be concealed, and wires must be laid through pipes. The electrical conduit is made of flame-retardant hard plastic pipe. When the hard plastic pipe is buried, a section of pipe not less than 0.5m from the ground shall be led out, and measures shall be taken to prevent mechanical damage.

The market should be equipped with a complete ventilation system. If there are multiple entrances and exits in the mall, natural ventilation can achieve the conditions of no odor and good air quality, and natural ventilation can be used. If natural ventilation cannot guarantee sanitary conditions, mechanical ventilation should be set up. If the market area is below 1000 square meters, an exhaust fan of not less than 2.2 kilowatts shall be installed. For every increase of 65,438+0,000 square meters above 65,438+0,000 square meters, the fan facilities will be increased by 0.22 kW accordingly.
