2 Terms
2.0.1 Stabilization ponds are treatment facilities that use ponds as the main structure and utilize natural biological communities to purify sewage. According to the amount of dissolved oxygen in the pond water, the type of biological population and the function of the pond, it can be divided into anaerobic ponds, facultative ponds, aerobic ponds, aeration ponds and biological ponds. According to the water quality standards achieved after treatment, it can be divided into conventional treatment ponds and deep treatment ponds. Synonym: oxidation pond. 2.0.2 Anaerobic pond
A stabilization pond that purifies sewage in anoxic conditions. 2.0.3 Facultative ponds A stabilization pond that purifies sewage in anoxic conditions in the upper layer and anoxic conditions in the lower layer. 2.0.4 Aerobic pond
A stabilization pond where the pond water is in the aerobic state and the sewage is purified. 2.0.5
5 Aeration pond
Aerobic pond or facultative pond equipped with aeration and oxygenation devices. 2.0.6 Biological pond A stabilization pond where aquatic plants are artificially planted or aquatic organisms are cultured. Biological ponds can generally be divided into aquatic plant ponds, fish ponds and ecological ponds. 2.0.7 Macrohydrophyte pond A stabilization pond where aquatic vascular plants or higher aquatic plants are planted. 2.0.8 Fish pond
A stabilization pond where fish are cultured and fed with algae and various plankton in the water to purify sewage and recycle resources to obtain economic benefits. 2.0.9 Ecological pond: A stabilization pond that uses bacteria, algae, plankton, benthic animals, fish, shrimp, ducks, geese, etc. to form multiple food chains to purify sewage. 2.0.10 Conventional pond: A stabilization pond used as a general biological treatment facility. 2.0.11 Maturation pond: A biological pond usually used in conjunction with a biological treatment facility, or a pond that is used after a conventional secondary treatment facility to further remove BOD5, pathogens, and reduce nitrogen and phosphorus content, also known as a maturation pond. 2.0.12 Controlled release pond: A stabilization pond designed to control sewage discharge and designed to solve the problem of exceeding the self-purification capacity of the receiving water body.
2.0.13 Complete containment pond: A stabilization pond that stores sewage without discharging it and only relies on evaporation to reduce the amount of water. 2.0.14 Sewage stabilization pond system
A series combination of pretreatment, facultative pond, aerobic pond or aeration pond, biological pond, etc. For the pond system that treats urban sewage or industrial wastewater with high organic matter concentration, it can be composed of pretreatment, anaerobic pond, facultative pond, aerobic pond or aeration pond, and biological pond in series.

3.1 Inlet and outlet control points
3.1.1 The inlet control point of the sewage stabilization pond system should be located at the inlet of the first stabilization pond. If there is a pretreatment facility, it should be located at the inlet of the pretreatment facility. 2 The outlet control point of the sewage stabilization pond system should be located at the outlet of the last stabilization pond.
2 Water quality evaluation indicators
Indicators.
It is advisable to select pH value, SS, and BOD items as the water quality evaluation of the sewage stabilization pond. Water quality and water quantity should be monitored at the inlet and outlet control points, and the treatment effect of the sewage stabilization pond should be measured by its removal efficiency. 3.2.3
When treating industrial wastewater with a water quality similar to that of urban domestic sewage, the corresponding water quality indicators can be increased or decreased according to the specific situation.
3.3 Accepted sewage quality
3.3.1 The quality of sewage accepted by the sewage stabilization pond system shall comply with the provisions of the third-level standard in the current national standard "Integrated Sewage Discharge Standard". 3.3.2 The concentration of toxic and harmful substances in the sewage entering the sewage stabilization pond system that inhibits or endangers the biological purification effect in the pond must comply with the provisions of Table 1 in the current national standard "Integrated Sewage Discharge Standard". 3.3.3 When an anaerobic pond is installed in the stabilization pond system, the influent BODs can be relaxed to 800mg/1.

4 Overall Layout
4.1 Pond Site Selection
4.1.1 The site selection of sewage stabilization ponds must comply with the requirements of the overall urban planning, and should be based on the principle of short-term and long-term expansion. Idle land such as abandoned rivers, ponds, valleys, swamps, wetlands, wastelands, saline-alkali land, and tidal flats should be utilized according to local conditions. 2 The pond site should be selected downstream of the urban water source and preferably on the upwind side of the minimum wind frequency in summer. The distance from residential buildings should meet the requirements of sanitary protection distance. 4.1.3 Engineering geology, hydrogeology and other aspects of the pond site must be surveyed and environmental impact assessment must be carried out when selecting the pond site.
4.1.4 The soil permeability coefficient (K) of the pond site should be less than 0.2m/d. 4.1.5
Regulations.
The selection of the pond site must take into account the flood discharge facilities and should meet the flood control standards of the area. When the pond site is selected on the tidal flat, the influence of tides and wind and waves should be considered. 4.2 Overall layout
The overall layout of the stabilization pond system should make full use of the favorable conditions of the natural environment. The overall layout should be compact.
4.2.2 The roads in the system should adopt single lanes, and the width should not be less than 3.5m; the main roads can be built with double lanes, and the width should be 6-8m.
4.2.3 The elevation design of the multi-pond system should allow the sewage to flow by itself in the system. When lifting is required, it should be lifted at one time.
The outside of the pond embankment should be planted with trees and green, and the width of the green belt outside the system should be greater than 10m.

5 Process Flow
5.1 Process Flow Design Principles
Use. bZxz.net
The sewage stabilization pond can be a self-contained system or combined with other sewage treatment facilities. When selecting the sewage stabilization pond process flow, it should be adapted to local conditions. 5.1.3
The process design should comprehensively consider the pollution source control, sewage pretreatment and treatment, and sewage resource utilization, and make a comprehensive design, and determine the appropriate plan through technical and economic comparison.
5.2 Sewage pretreatment
1 Pretreatment facilities should include screens, grit chambers, sedimentation tanks, etc., and their design should comply with the provisions of the current national standard "Outdoor Drainage Design Code". 5.2.2 Stabilization pond system pretreatment should adopt structures with a long sludge discharge cycle and low investment and operating costs.
5.3 Sewage stabilization pond system
The stabilization pond system can be composed of multiple ponds, either in series or in parallel. 2 In a multi-level pond system, the area of ​​a single pond should not be greater than 4.0×10°m2. When the area of ​​a single pond is greater than 0.8×10m2, a diversion wall should be set up. 5.4 Sludge treatment and disposal
1. The grit chamber (channel) should be discharged mechanically or by gravity, and a sand storage tank or sand drying field should be set up.
Sludge dehydration should be carried out by natural air drying in sludge drying bed, or mechanical dehydration can be used. Engineering Construction Standard Full Text Information System
