How do VOC cubic containers

Construction and operation of the aeration treatment plant in difficult conditions

When the area of ​​permeable soil and groundwater to dig and dig, problems with sewage hardly arises - septic tanks of concrete rings quite cope with the task. In conditions when perched most of the year in almost a bayonet spade, and with the best scenario to its 1.5 meter, more and more difficult. Ready-aeration unit (AU) for the average consumer are quite powerful, and self-made must be tight - either plastic or of reinforced concrete. Member of our portal with the nickname aazinus extra funds did not have, as well as the construction took place in the winter, then chose to collect his AU from used plastic cubic containers. His experience will be useful to anyone with a similar situation with GWT and there is no financial ability to acquire the factory LOS (local treatment plant).

The house stands on a bolt, a floating foundation - caisson until flows. Perched: mezhsezone - 30 cm; summer - 70 cm in drought times to 1.5 meters left. The house has five people live, sometimes seven. I had to do in the winter. From pouring concrete refused. In addition to pour concrete into the swamp - need some good pumps at pumping. According to calculations, the volume of discharge 7 × 150 = 1050 liters, in total - the cube. Safety factor (the cleaning) - 3.5 days. The volume of the septic tank (more correctly, the local treatment plant, VOCs) 3-3.5 m³.

After examining forum aazinus selected circuit design with aeration:

• first cube - sump;
• second - aerated;
• third - aerated, but weaker to yl decanted.

Materials and components

Evrokuby topikstarter bought cheap - three pieces for two thousand rubles. Looking ahead, it may be noted that such a low price is linked to the specific application - capacity was out of the chemicals (raw materials for superglue) and food are much more expensive. Residues content to clean and recycle (washed with petrol / acetone / solvent on an iron pallet, plums burned, coal packed and discarded in the trash). Besides cubes for future installation aazinus I bought:

• Chinese manufacture compressor (3 thousand);
• fine aeration elements (2 to 800 rubles);
• US boot for bacteria (2000 rubles) - in fact, just a plastic mesh, but expensive, so sawed and made a load of plastic mesh for fences.

The rest of the transoms - all that remained of the building, it is a heater (Epps), and sewer pipes (110 mm), and other "small things."

Assembly and installation of septic tank

Evrokuby top cut "window" pipe drilled holes (input / output / overflow) inserted pipe, fixing sealant joined first wire, further, welded connection by welding to the frame containers. Aerators installed on stainless steel, load suspended in the second and third cubes. Cuba insulated sheets Epps as ballast between the wall and cubes to surfaced during the installation, use and sand mixture was overdue construction. Force majeure, meanwhile, has not been canceled - "But then there was a surprise - the suspension for six months." I buried, insulated, and left to the next stage.

He continued to build in the spring, with the cover installation.

For lifting from the bottom of the second and third sludge chamber, aazinus I did airlift - the idea spied on a thematic exhibition in one of the foreign companies. Implemented in relation to their conditions: air is supplied through a thin tube from the bottom, so that aeration bubbles break up the crust formed. Air rises upwards - yl sinks.

Launched installation worked three months - considering lowering, treatment volume of 2.5 m³. To me this was not enough: cast concrete (wire waste, old cement piece of iron, the inside of the DSPs) and other waste in the insulation. The result was a well-distributor with an adjustable level and minimal aeration, for:

• smoothing salvo reset of whirlpool (350-400 liters);
• distributing effluent therefrom by filtration fields;
• maintain and regulate the effluent level above the groundwater to soil in the back with no VOCs collected.

To the geese do not hatch insulation, obbil Verkhovyna boards, iron and covered with earth, to warm the pipe and duct to the duct side primotat heating cable. Field of the filtration drilled pipe (20 meters, could buy a perforated, has been used) for the drainage tube - 20 meters.

Drainage sand: ditch, 0.5 to 1 meter; above, after filling, geotextile to avoid silting; insulation, not to peremerzalo (all the same Epps, the remainder of the building); priming. Sandy loam to loam soil with good permeability, although accurate measurements aazinus did, drainage volume, too, "the eye." The level of liquid in the installation is adjusted in level with the ground via raspredkolodtsa. Total treatment volume about 5,5 m³ three cubic containers is 2.5 m³, plus a distribution well, and another 2.5 m³ to about 0.5 m³ drainage pipes. During the first year of pumping is not needed - the sludge accumulated slightly.

To accelerate the infection, increasing the mass of bacteria and to improve the degree of purification, all the cells in addition to the loading grids filled expanded clay. Immediately after exposure, sewage sludge are infected in the first chamber, which AeroLift realize the second and third compartments. In fact, the fluid rotating in the washing machine - aeration is continuous circulation, and due to its location near the wall of the aerator, "oxygen stream" blows with the download grown in them bacteria. The degree of purification can be seen in the photo (well-distributor).

I made to a conclusion - with evrokuby contact is not necessary, it is easier to cast in concrete, but then you have to wait for dry weather. While flooded raspredkolodets, although in the summer heat on the discharge pump is not shut off a few days to wash toilets... It can be tough and chemistry - smell appears, disappears during the day - the bacteria die, but then again, multiply. Here's a system I did.

Clamps substituting brazed polypropylene tubes. The cold air leaks are, we have to pull. The exhaust system of the year to fully serve the house. Then we will see. She made her poverty, used to be regretted time and now, in the crisis, a lot of time. Special thanks to the forum - here learned a lot of knowledge. Also grateful forumchanin Shcherb39 and the topic of the surface of the septic tank cubic containers.

in winter aazinus dismantled setup and air leaks eliminated, which provoke the formation of condensation and frost on the need for continuous heating duct.

Photo collection.

By setting for summer 2015.

Zizka became clearer - eliminate air leaks, settler got the flora and fauna - mosquito larvae in large quantities eats organic, water has become clearer than in the winter. I believe that it is possible to compare the effects of eco factory VOCs and my homemade with integrated cleaning. I remind you that this ready to install 5 m³ (8-10 people), worth about 150 thousand, plus the installation, plus various transoms. I have everything worked out about 30 thousand rubles, but, taking into account non-market pricing.

Under non-market pricing craftsman implies:

• free labor (two Uzbeks assisted accommodation);
• own free labor, both in the assembly, and for the study of case materials and design;
• Waste - delayed cement, wire / used for reinforcement of metal, Epps, instrument occupies, pipes, fittings, etc. (about 90% of the consumables remaining construction of the house). It was all junk, so, too, is free.

But if all of the above translate into market prices, the total amount would be increased considerably. However, the company then offered "master" of such amount for the sum of five hundred thousand to one million rubles.

I do not regret it come from and contacted. This, of course, is not supersonic interceptor, but only sewage, but warm, which do not pollute their land and drywall Mother Nature.

And the effectiveness of a self-made installation is visible to the naked eye.

This fluid from the dispensing well for final cleaning is still supplied to the soil filter in drainage.

As of May of this year:

• Installation is not ideal, but still maintains a family of four;
• For four years, once pumped sludge in the third section, and never in the first two, the pumping is planned for this summer;
• We need to change the design of airlift, as they become clogged and have to be cleaned. If this is not done immediately reduced cleaning performance.

Output

As topikstarter notes homemade aeration system - a workable option if there is no money in the factory, but "to be honest, not a gift." Especially if there is a danger of squeezing frost heaving. Nevertheless, carefully designed and implemented homemade effective even in harsh environments. A deal with the assembly of "designer" or deliver finished aeration unit - as usual, everyone chooses for themselves and by themselves.
