Treatment process and device for wastewater containing benzene

The invention relates to a treatment process and device for wastewater containing benzene. The device comprises a pretreatment unit, an ozone oxidation unit, a biochemical treatment unit and a double-membrane advanced treatment unit which are sequentially connected. The treatment process comprises the steps of: firstly adding lime to the wastewater for softening the wastewater, then adding a coagulant for polyferric sulfate coagulation, adding a flocculating agent for flocculation, precipitating and clarifying, and then sending clear liquid into a sand filtering layer, wherein yielding water enters an ozone contact tank for ozone aeration and oxidation, carrying out biochemical treatment on the wastewater subjected to ozone oxidation by adopting a biological aerated filter treatment process and a moving bed biomembrane reactor so as to further degrade COD (Chemical Oxidant Demand), and carrying out ultra-filtration and reverse osmosis double-membrane treatment on the wastewater for desalination. According to the invention, through combination of the treatment units, the removal rate of CODcr with benzene rings in the fed water can be up to above 80%, and the removal rate of SS (Suspended Solids) is about 90%, and the removal rate of ammonia nitrogen is above 85% before fed water enters a RO (Reverse Osmosis) membrane. For a double-membrane system, the cleaning period is increased by 3-4 times, and the service life of the membrane is prolonged by 1-2 years.

Integrated window-type air conditioner

The invention discloses an integrated window-type air conditioner. The air conditioner comprises an indoor panel, a cabinet, an evaporator, an indoor fan, a condenser, an outdoor fan, a volute, a compressor and a base plate, wherein the volute comprises a fixed volute and a rotatable volute; the fixed volute forms a cambered surface which semi-encloses the outdoor fan in the cabinet; the rotatable volute is connected to a lower section base plate and rotates by taking a connection position as a rotating shaft; and the lower section base plate is provided with an outdoor vent hole. When the rotatable volute is folded, the outdoor vent hole is enclosed; when the rotatable volute is unfolded, the fixed volute and the rotatable volute form a continuous volute inner surface and heat-exchanged air is guided to flow outwards from the outdoor vent hole. The folded volute occupies a smaller space in the cabinet, so that the overall height of the outdoor side cabinet is reduced and transportation cost is saved. The unfolding degree of the rotatable volute is determined according to the practical indoor condition, so that the air supply volume and air exhaust volume in the cabinet can be adjusted freely according to the practical condition and the running state of the air conditioner is optimized.
