1. Buried below the surface, the surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of elastic three-dimensional packing material is used in the pool, with a large specific surface area and easy biofilm formation and detachment by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.

3. The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of the filling material, and the microorganisms are in their own oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using fecal trucks to suction or dehydrate into sludge cakes for external transportation).

4. The entire equipment processing system is equipped with a fully automatic electrical control system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, only timely maintenance and upkeep of the equipment is required.

5. The sewage treatment equipment is composed of steel structure and adopts AO treatment process. Advanced anti-corrosion technology is adopted to make the equipment resistant to acid, alkali, salt, gasoline, kerosene, etc., aging and abrasion, with a designed anti-corrosion life of more than 30 years.

Scope of application:

Hotels, restaurants, sanatoriums, hospitals; Residential communities, villages, and towns; Stations, airports, seaports, and ships; Factories, mines, troops, tourist attractions, scenic spots; Various industrial organic wastewater similar to domestic sewage.

How many methods of using buried domestic sewage treatment equipment? Capable of treating comprehensive wastewater from living systems and similar organic wastewater; It is made of glass fiber reinforced plastic and stainless steel, and has excellent characteristics such as corrosion resistance and aging resistance, with a service life of more than 50 years;? The complete set of equipment is simple to construct and easy to operate. All mechanical equipment is automatically controlled, and all devices can be installed on the ground; Detailed Introduction

1、 Overview

With the growth of economy and population, the pollution of nature has been increasingly valued by human beings. Based on the summary of the operating experience of domestic and foreign domestic sewage treatment devices, combined with our company's own scientific research achievements and engineering practice, we have designed a complete set of organic wastewater treatment devices that can be buried. The equipment adopts advanced processes and manufacturing technologies from the late 1990s at home and abroad, and produces the LHC series of sewage treatment equipment mainly made of fiberglass and stainless steel. The main purpose is to meet the discharge standards required by users after treating domestic sewage and similar industrial organic wastewater with this equipment. This device is mainly used for the treatment of domestic sewage in residential communities (including villa communities), high-end hotels, hospitals, comprehensive office buildings, and various public buildings. The effluent quality treated by this device meets the national discharge standards. The entire set of equipment can be buried underground, so it is also known as "buried domestic sewage treatment equipment".

Our company's buried domestic sewage treatment equipment adopts internationally advanced biological treatment technology, which integrates the removal of BOD5, COD, and NH3-N. It has stable and reliable technical performance, good treatment effect, low investment, small land occupation, and convenient maintenance. Our company can also provide supporting reclaimed water reuse equipment according to customer requirements.

2、 Product Features

1. Buried below the surface, the surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of elastic three-dimensional packing material is used in the pool, with a large specific surface area and easy biofilm formation and detachment by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.

3. The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of the filling material, and the microorganisms are in their own oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using fecal trucks to suction or dehydrate into sludge cakes for external transportation).

4. The deodorization method of this buried domestic sewage treatment equipment not only uses conventional high-altitude exhaust, but also includes soil deodorization measures.

5. The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.
