Detailed description

1T/H Buried integration sewage treatment plant/wastewater treatment system.

Dispose domestic sewage, make the wastewater achieve designed effluent standard.

This plant adopt“ Biological Contact Oxidation” technology to dispose sewage, main plant was designed as frame type steel structure.

Workflow

Sewage--- grilling well---regulating reservoir---A level organisms reservoir---O level organisms reservoir---second sediment reservoir---disinfect reservoir

Related parameter

 1)Equalize tank:  capacity--10T       size---2.5*2*2.5m            available water depth:2.3m

   Function:Adjust  sewage yield and quality, ensure the biochemical treatment device working continuously and smoothly. Puddle, ladder are designed in this reservoir for easily install and maintain.

2)Sewage lift pump    2 set

3) Draught fan             2 set

4)Integration main machine   1unit      size---4.5*1.5*2.25m   material---steel structure&anticorrosion  carbon steel

5)Control cabinet       1 set       auto&  manual control

Feature : automatically operation, alerting when water exceed warning water level

performance requirements

1. Draught fan, water pump were  centralized controlled  by control cabinet ,can control by auto  and  manul. draught fan, and water pump can working alternately.

2. Draught fan, water pump can automatically turn on and off to adapt water level

3. When sewage cutoff, draught fan can automatically intermittent operation

4. Auto control cobinet protection for electric shortage, pressure protection, water level protection

5. Hilary Schneider, Omrom, Siemens electrical equipments in control cabinet

 Stench prevention

1.Each pool were airtight in the whole plant to prevent stench escape.

2.Every possible stench pool were installed with air tub to aerating and aerobic digestion. 

Noise control

1. Adopt buried design, little affect to outside world.
2. Adopt lower noise type draught fan, plant noise≤80dB,silencers were installed in exit and entrance of the draught fan.

Sludge treatment

1. Sludge was discharged  by second  sediment  pool, mostly returned to A level organisms pool to get treatment, thus reduce the output of sludge.

2. Some of the sludge returned to the sludge pool to get gravity concentration and aerobic digestion, thus can reduce the sludge volume.

3.Regular pumping sludge out.

Anticorrosion

Use reinforced concrete structure in civil building and carbon steel in main plant. Equipment brushed with epoxy coal bitumen coat. Pipes inside the plant are all use ABS high quality engineering pipe, thus to ensure equipment’s working life reaches 30years.
