Purification effect of buried small sewage treatment equipment

The buried small-scale sewage treatment equipment is specially designed for villas and some small-scale industrial production. The buried sewage treatment equipment used to treat a large amount of such domestic and industrial sewage produces chemical oxygen demand, biochemical oxygen demand, and free High removal rate of ammonia, ammonium ions and total phosphorus, and has the comprehensive effect of treating sewage, decorating the environment and environmental protection and energy saving water source.

Sewage not only affects the ecological environment, but even affects the health of residents, so sewage treatment is one of the problems that need to be solved urgently in our country. Nowadays, the most technical means used in sewage treatment is to rely on sewage treatment equipment, but among the many types of sewage treatment equipment, how to find cost-effective equipment.

The buried small sewage treatment equipment adopts the AO biological treatment process, and the advantage of this process is that the biological contact oxidation tank adopts the push-flow biological contact oxidation tank, and the treatment effect of the push-flow biological contact oxidation tank is better than that of the mixed type. Or two or three series series complete mixed biological contact oxidation tank. And it is smaller than the activated sludge tank, has strong adaptability to water quality, good impact resistance, stable effluent quality, and no sludge bulking. At the same time, a new type of elastic three-dimensional filler is used in the biological contact oxidation tank. It has a large actual specific surface area, and it is convenient for microorganisms to hang and remove the film. Under the same organic load condition, it has a higher removal rate of organic matter than other fillers and can improve The solubility of oxygen in water. In addition, the moisture content of the sludge produced by the biological contact oxidation tank is much lower than that of the sludge produced by the activated sludge tank. Therefore, the amount of sludge generated after the sewage passes through the sewage treatment equipment is small, and it generally only takes about 90 days to discharge the sludge once.

Standard note points for buried small sewage treatment equipment:

1. Before installing the buried small sewage treatment equipment, all relevant companies will send special personnel to clean up and inspect the integrated equipment installed by the buried small sewage treatment equipment according to the equipment packaging content and related agreement documents, and make records and check. However, critical components must be inspected and accepted according to quality standards. After the inspection, an unpacking inspection record is formed for record.

2. Data acceptance, check each box according to the package content, and complete the relevant information of each integrated device.

3. Appearance inspection, check whether the comprehensive equipment of the arriving goods is obviously damaged, damaged or unqualified, and contact relevant personnel in time to explain the situation and carry out follow-up work.

4. Spare parts This is a situation that many on-site personnel are prone to neglect. Most spares come with integrated equipment, but this site is temporarily unavailable. This requires project managers to collect and save them separately, and to keep records. Finally, when all the work is done, it will be handed over to the relevant units.

5. The buried small sewage treatment equipment is responsible. After the disassembly and integration of the integrated equipment is completed, the equipment should be handed over to the construction unit immediately.

6. The on-site management personnel should confirm the receipt of the equipment in time according to the arrival of the equipment, and keep the documents.
