Description

Sewage natural processing system

Technical field

This application involves sewage natural processing system technology fields, more particularly to sewage natural processing system.

Background technique

Sewage natural processing is to instigate sewage by certain structures, is reached using the effect of aquatile and microorganism To a kind of sewage treatment method for dirty Organic substance in water purpose of degrading.Typically, sewage natural processing system includes stabilization pond System, land treatment system and 3 kinds of artificial wet land system, are summarized as follows.

Oxidation pond, also known as biological pond or stabilization pond are a kind of facilities handled using natural purifying ability sewage General name.Oxidation pond purification process is similar to the self purification process of natural water, comes by the microorganism, algae and plant grown in the pool Handle sewage.Oxidation pond is, by the planting aquatic plants in the pool, to carry out aquatic products using solar energy as primary power and aquatic bird is supported It grows, forms artificial ecological system, in the case where solar energy, that is, solar radiation provides promotion of the energy as primary power, pass through oxidation pond The material transport of a plurality of food chain, conversion and the transmitting step by step of energy, conversion in stabilization pond, will enter organic dirt of sewage in the pool Dye object is degraded and is converted, and as resource reclaim in the form of water plant and aquatic products, aquatic bird, the sewage of purification can also be made It is recycled for regenerated resources, makes sewage treatment with using combining, realize sewage treatment recycling.In China, especially It is in the area of water shortage arid, and oxidation pond is the effective ways for implementing the resource utilization of sewage, so stabilization pond processing is dirty Water has become the technology widelyd popularize.

Land treatment system is to be also known as waste water to sewage using soil and wherein microorganism and root system of plant to handle, Promote the job facilities of crops, herbage or arboreal growth using wherein moisture and fertilizer point again simultaneously.Belong at perennially sewage Science and engineering journey is usually used in replacing advanced processes after the sewage second-level sewage treatment of small and medium-sized cities.By precipitating pretreatment, the water storage of sewage The systems such as pool lake, irrigation system, subdrainage composition.Processing mode is generally sewage irrigation, diafiltration and overland flow.Sewage fills Irrigate the growth that will promote plant in sewage discharge to soil by sprinkling or gravity flow；Diafiltration i.e. by sewage discharge to coarse sand, Through filtration process and recharge of groundwater on the soils such as soil and sandy loam.

Artificial swamp is the ground similar with marshland by manually building and controlling operation, sewage, sludge is had control Dosing to the wetland through manually building on, sewage and sludge mainly utilize soil, people during flowing in a certain direction Work medium, plant, the physics of microorganism, chemistry, the triple synergistic effects of biology, a kind of technology that sewage, sludge are handled. Its mechanism of action includes absorption, delay, filtering, redox, precipitating, microorganism decomposition, conversion, plant masking, residue product Tired, water transpiration and Nutrient Absorption and all kinds of animals effect.Artificial swamp is a comprehensive ecosystem, its application ecology Intergrowth of species, substance principle of recycling and regeneration in system, structure and orthofunction principle, Pollutants in Wastewater matter is benign to be followed promoting Under the premise of ring, the productive potentialities of resource are given full play to, prevent the recontamination of environment, obtain the best of sewage treatment and recycling Effect.Artificial swamp type generally comprises surface flow artificial marshland, drowned flow artificial wet land and irrigation canals and ditches artificial swamp.Wherein, undercurrent people Work wetland divides horizontal drowned flow and vertical current constructed wetland again.

Currently, widely formula is applied to sewage treatment, the processing of middle advanced water treatment to system above alone or in combination.In reality During trampling it is commonly found that oxidation pond, surface flow artificial marshland that there are pollutional loads is low, purification efficiency is slow, land occupation is big etc. restricted lacks It falls into；Pollutional load low pass is often embodied in hydraulic surface loading and is generally less than 0.1m³/m²D, land occupation are usually embodied in ton water greatly and account for Ground compares more than 10, and hydraulic detention time is more than 10~20d；Subsurface flow wetland system exists gathers in for the emergent aquactic plant of clean-up effect Cumbersome, significant blocking or the hardened problem of medium are conserved, purification efficiency is not only substantially reduced, function more or even quickly occurs It can lose.It finds according to statistics, current wetland is generally run life cycle 2~5 years, almost without that can reach 8 years or more.This Greatly limit the practical application of artificial swamp.
