Integrated rotary plastic three-form septic tank

Basic structure and principle:

1, precipitation decay area

The domestic sewage is precipitated, the more significant material is sunk to the bottom of the pool for dung treatment, and the part with a small proportion floats on the surface of the water and can be pulled out from the cleaning mouth. At the same time, the waste water produces a feces function, so that part of the complex structure and difficult to decompose organic matter is degraded into easily decomposed substances.

2. Partition area

The direct flow water is converted into circulation water, which increases the retention time of sewage in the tank, makes the contact time between sewage and precipitated sludge in the tank longer, produces more microorganisms, and decomposes and swallows the sewage.

3, filter processing area

The use of advanced biofilm treatment technology at home and abroad, after a certain period of cultivation, a large number of microorganisms multiply on the filter surface to form biofilm, sewage and filter surface biofilm contact, organic matter is trapped by microorganisms, adsorption and decomposition, to achieve sewage purification treatment.

Main features:

1, the volume of 1.0-1.5m3, in line with the "o/swY011-2015 three-format septic tank" standard. The volume of the three cells is divided in a ratio of 2:1:3

2, optimized structure design, mature process technology, high product strength, acid and alkali resistance. Anti-corrosion.

3, roll molding once, no need for two body docking. Solve the problem of leakage.

4, save labor, save time, long service life.

Installation instructions:

1. Dig a cuboid pit with a length of 2 meters, a width of 1.4 meters and a depth of 1.2 meters, and use 50mm concrete as a cushion layer.

2. Put the three-cell septic tank flat, connect the chemical manure pipe and exhaust pipe, and the exhaust pipe should be 20-50cm higher than the toilet house.

3. The backfill soil should be semi-dry and semi-wet, tamped layer by layer, and backfilled layer by layer until the ground level to prevent the collapse of the urn body. Tilt. The filling shall be carried out in two stages: the first backfill half to a depth of 0.6m. Sprinkle a small amount of water to tamp and level, and then fill the earth twice until the surface is even. The top three exits are 5-10 cm higher than the ground, and cement mortar is used around the exit cover to strengthen the anti-seepage fixing effect.

4. The bedpan should be parallel around the installation, and the vertical should be high before and low after the longitudinal (5° inclination) to ensure that the bedpan does not leave water after flushing. The distance between the back end of the bedpan and the wall should be between 20-25cm, and the external insulation layer should be added to the bedpan in cold areas. The squat toilet around the first with fine sand, and then with 2 cm cement mortar leveling.

5, the installation of water storage barrel outlet pipe must ensure natural placement, not S-shaped laying, to prevent water icing. The water storage bucket should be placed behind the bedpan. When installing an indoor water storage bucket, the cover of the bucket is 10cm below the ground and can be covered with thermal insulation materials. When backfilling, the water storage bucket should be filled with water first, and then filled with earth and tamped.
