Abstract
Description
1. Technical field
[0001] The invention relates to a method for purifying domestic wastewater, in particular to a method for purifying bathing wastewater that can make bathing water recycled. 2. Background technology
[0002] At present, there are many methods and equipment for purifying bathing wastewater, so that the wastewater after bathing can be reused to achieve the purpose of saving water. For example, the utility model patent "air flotation purifier" with the publication number CN-2154258Y, the utility model patent "package type bath wastewater purification, purification and reuse device" with the announcement number CN-2310611Y, etc., and the closest to the present invention The existing technology is the patent No. 88105013 invention patent "method and device for purifying bath water". The method is to use low-pressure air flotation and balanced overflow to pump the suspended solids and part of the sewage in the bath into the air flotation tank, and then air again....
Examples
Embodiment Construction
[0011] Such as figure 1 As shown, wastewater filtration is to make the wastewater after bathing enter the hair filter through the sewer, filter out hair, blades, wet cream, soap flakes and other sundries, enter the sump, and mix with flocculant (Al 2 o 3 Polymer) mixed, pressurized by the water pump, jet storm into the flocculation reaction tank, fully condensed after three deflections, and complete the flocculation treatment; after the flocculation treatment, enter the air flotation tank for air flotation; after the air flotation, use the slag scraper to remove The scum is scraped into the slag pool, that is, solid-liquid separation; part of the water after solid-liquid separation is returned to the air flotation step, and becomes dissolved air water after passing through the dissolved air generator, and air flotation is carried out on the flocculated flocculated water; the other part of the water is mixed with After the adsorbent and filter aid are mixed, the filter pump en...
