Description

A kind of outer row pond of sewage disposal system

Technical field

This utility model relates to a kind of sewage-treatment plant, more specifically, it relates to the outer row pond of a kind of sewage disposal system.

Background technology

Current China has quite a few area Sewage Treatment Facilities complete not, processes means also comparatively backward, and Small Urban is especially true. acceleration along with China's wide geographic area Urbanization Construction, more and more many population is concentrated to cities and towns, how to process sanitary sewage timely and effectively, recycle value is even produced so as to innoxious, thus ensureing the hygiene and health of the people and implementing environmental conservation, become governments at all levels and social encountered important topic. the end of sewage disposal system is generally arranged arranges pond outside one, it is used for collecting the water after storage processes, and as the facility docked with outside city planting ductwork, although but process through multiple tracks, collect the chemical composition that the water in outer row pond also still suffers from not removing, water there will be after standing a period of time hardening incrustation phenomenon, also can discharge foul smell, corrosivity volatile matter, because row pond, except collecting, storing water, also should possess the reprocessing function of necessity in addition, otherwise outer row pond is likely to and becomes polluter. the utility model patent that publication number is CN201245532Y discloses a kind of cities and towns public toilet faeces on May 27th, 2009, septic tank sludge scum silica frost focuses on station arrangement, belong to the environmental protection of town environment hygiene department application, environmental sanitation treating apparatus, including grid sewage-removing machine, solid-liquid separating machine, centrifugal dehydrator, reception tank, elevator pump, rotatable solid-liquid separating machine, screw pump, Horizontal centrifugal dehydrator, excrement dirt case yi word pattern layout front and back successively are laid, reception tank front end is equipped with grid sewage-removing machine, pipeline after screw pump is also communicated with chemical feed pipe, rotatable solid-liquid separating machine, the pipeline connecting municipal sewage pipe network all it is equipped with after Horizontal centrifugal dehydrator, this device orderliness is clear, definite functions, compact in design, floor space is little, reduced investment, upper detective, construction period is short, instant effect, technics comparing is simple, high treating effect, specification scale is many, it is not only suitable for big and medium-sized cities, it is also applied for small and medium-sized cities and small towns, the anaerobic tank in new rural village public lavatory is cleared and is focused on utilization. but this utility model biases toward the layout of entirety, and in idiographic flow, the technical scheme of each segmentation does not clearly provide.

Utility model content

The Sewage Treatment Facilities of current Small Urban is complete not, process means are also comparatively backward, treatment effeciency is low, treatment effect is not thorough, it is difficult to tackle the environmental protection pressure that extensive urbanization brings, for solving this problem, this utility model provides a kind of process more thoroughly, is favorably improved the outer row pond of the sewage disposal system of sanitary sewage disposal ability.

The technical solution of the utility model is: the outer row pond of a kind of sewage disposal system, described sewage disposal system includes unloading dirty pond, prime processes pond and solid-liquid separating machine foundation ditch, solid-liquid separating machine foundation ditch is provided with the conjuncted equipment of sand setting filtering residue, outer row pond connects with the conjuncted equipment of sand setting filtering residue, outer row pond is enclosed construction, is provided with blender in outer row pond. Owing to outer row pond is enclosed construction, it is possible to prevent foul smell and corrosivity volatile matter in a large number to outward leakage, and blender stirs the water after the process collecting in outer row pond, water is made constantly to flow, can prevent from collecting water hardening incrustation, it is easy to arrange in pond outside proceed dosing post processing, purifies water further to reach environmental protection standard such that it is able to carry to city planting ductwork.

As preferably, outer row pond and prime process the junction being connected with return duct, return duct and outer row pond between pond and are provided with reflux pump. Prime processes the first treatment facility that pond is sewage disposal system, may separate out bulky grain solid phase, each process equipment in the solid-liquid separating machine foundation ditch in little granule solid Ze Hou road separates further, solid phase is progressively separated, liquid phase then eventually flows in outer row pond, pond can occur various complex chemical reaction form sediment owing to arranging outside, and flow process be likely to bring other solid matter into, because the water arranged in pond in addition need nonetheless remain for carrying out solid-liquid separation. Water in outer row pond is led back prime along return duct and processes pond by reflux pump startup, reenters handling process, carries out solid-liquid separation further, makes solid phase in the water of outer row pond more thoroughly to be eliminated.

As preferably, being provided with the outer comb leading to outside pond in outer row pond, outer comb is provided with efflux pump. Outer comb can be directly accessed city planting ductwork, and the water in so outer row pond is after reprocessing, and water up to standard can directly input city planting ductwork under the driving of efflux pump.

As preferably, being provided with sewage at the bottom of solid-liquid separating machine Foundation Pit and between outer row pond and reclaim pipe trench. Solid-liquid separating machine foundation ditch is lower than ground, and the sewage disposal device in solid-liquid separating machine foundation ditch has water to spill when processing sewage unavoidably, and arranging sewage recovery pipe trench can guide the water spilt to outer row pond, it is to avoid solid-liquid separating machine Foundation Pit prodelta clay water.

As preferably, prime processes pond and solid-liquid separating machine foundation ditch is externally provided with solid phase surge drum set-point, also is provided with sewage and reclaims pipe trench between solid phase surge drum set-point and outer row pond. After in prime process pond and solid-liquid separating machine foundation ditch, each equipment carries out different grades of solid-liquid separation, isolated solid phase is collected in solid phase surge drum, solid phase surge drum bottom opening is to drain moisture in solid phase, solid phase surge drum is placed on solid phase surge drum set-point, the moisture that drop goes out can pass through sewage and reclaim in pipe trench importing outer row pond, it is to avoid pollutes field ground.

As preferably, outer Pai Chi top is provided with outer row pond ventilation unit. Outer row pond ventilation unit makes the harmful gas produced in outer row pond can controllably discharge, collect, it is prevented that harmful gas leaks and keeps outer row pond internal gas pressure stable.

As preferably, blender is positioned in the middle part of outer row pond. Blender is arranged in the middle part of outer row pond, it is possible in more uniform drive pond everywhere water flowing.

The beneficial effects of the utility model are:

Sewage disposal is more thorough. This utility model can make water in outer row pond keep flowing, it is prevented that hardening incrustation, and can again import circulation process and repeatedly process, and can also control the discharge of the harmful gas generated in outer row pond simultaneously, and sewage disposal is more thorough, meet the requirement of environmental protection better.
