Description

Integrated water treatment equipment

The utility model relates to a kind of integrated water treatment equipment.

Existing water treatment device adopts the chemical coagulation method more, and promptly the source water after the dosing successively by suspension body refuse clarifying chamber, particle filtration layer, behind the removal suspended impurity, is supplied with the user by bottom water distribution facility from bottom to top after the routine sterilization.This device can only be handled I-II class water body.Chinese patent 89200202.6 discloses a kind of " efficient quality purifying device for water ", it only is to carry out water conditioning by particle filtration after with the source water precipitation, thereby can not effectively remove the III-IV class water body that contains more dissolubility pollutant and lipid pollutent, and perforate water distributing pipe, shore pipe, washpipe that it adopts stop up easily.

The purpose of this utility model provides a kind ofly can effectively handle with serious pollution III-IV class water body, and pipeline is difficult for blocked, and spoil disposal integrated water treatment equipment more completely.

The main technical schemes of integrated water treatment equipment of the present utility model is: this device comprises housing, water inlet pipe, aeration air supporting settling pit, water distributing area, the tube settling district, the catchment area, treat filtered water section, sand filter blanket, the gravel supporting layer, the perforation screen plate, clear water zone, at least one ejector of installing on the water inlet pipe is deep into the bottom of aeration air supporting settling pit, aeration air supporting settling pit top connects at least one row's scum silica frost pipe, the bottom is connected with the sediment outflow pipe of band valve, aeration air supporting settling pit is connected from the bottom along the common tangent direction by pipe with first eddy flow flocculation reaction chamber, six all eddy flow flocculation reaction chambers begin successively from first that alternately---bottom---top alternately connects along the common tangent direction by pipe from top, the shore pipe that has mud valve is connected first, three, the bottom of five eddy flow flocculation reaction chambers, draw in distribution main and the water distributing area at least one annular water distribution pipe coupling that has a downward notch from the bottom of the 6th eddy flow flocculation reaction chamber, taper collection mud annular groove is arranged at the bottom of water distributing area, the bottom of collection mud annular groove communicates with the notch of opening on annular shore pipe, annular shore pipe and the total pipe coupling of spoil disposal that passes housing, water distributing area successively with the tube settling district, biological contact oxidation chamber, the catchment area is connected, in the catchment area, there is at least one annular header that has the notch that makes progress to link to each other with water header, water header is connected on the flush discharge pipe by the total valve that catchments, the flush discharge pipe that has the flush discharge valve stretches into treats filtered water section, treat filtered water section successively with sand filter blanket, the gravel supporting layer, the perforation screen plate, clear water zone is communicated with, the clear water rising pipe that has the clear water outlet valve links to each other with clear water zone, on the clear water rising pipe and be connected to the band valve the chlorination pipe.

After adopting said structure, water treatment procedure of the present utility model is as follows: the source water that the starting working shaft will add flocculation agent injects aeration air supporting settling pit through water inlet pipe, be installed in self-priming ejector on the water inlet pipe with the inhaled air high dispersing in the water of source, give source water oxygenation, again this gas one liquid two-phase flow is injected aeration air supporting settling pit bottom, wherein big and heavy contamination precipitation is in the bottom, pond, discharge sand setting and scum silica frost respectively by sediment outflow pipe and row's scum silica frost pipe on the floating top, pond that combines in of bubble that lighter impurity such as lipid pollutent are discharged by ejector.Then water flows into six eddy flow flocculation reaction chambers by the pipe coupling of tangential direction, form rotational flow, flocculation agent thorough mixing in the water is reacted, so small colloidal solid is condensed into thick alumen ustum flco in the water, fully the water after the flocculation reaction enters water distributing area through distribution main and annular water distribution pipe, the water that notch on the annular water distribution pipe will form big alumen ustum is evenly distributed to bottom, tube settling district, neither can destroy big alumen ustum, again can be not blocked.Water in the water distributing area enters the tube settling district from bottom to top equably, body refuse flco in the water sinks to entering taper collection mud annular groove, the annular shore pipe of taper collection mud annular groove and the fluting that cooperates with it can produce good syphonic effect, discharges body refuse effectively and can not block pipeline by suction.The liter waterborne of post precipitation enters biological contact oxidation chamber, in the former processing, removed in the water the deleterious impurity of carrying out a biological disposal upon, reduced the biological treatment load, enough dissolved oxygens are provided, for good condition has been created in biological treatment, therefore in biological contact oxidation chamber, dissolubility pollutant is just by abundant biological degradation in the water.Current water inlet catchment area, annular header of process and water header enter treats filtered water section, has notch upwards on the annular header, helps catchmenting evenly, stablizes, and be difficult for obstruction.The water for the treatment of filtered water section flows into clear water zone through sand filter blanket, gravel supporting layer, perforation screen plate after filtering residual impurity from top to bottom, and chlorination after the clear water rising pipe is drawn is sent into pipe network and used for the user.As seen, integrated water treatment equipment of the present utility model both can have been handled I-II class water body also can effectively handle the III-IV class water body that contains dissolubility pollutant and lipid pollutent, pipeline is difficult for blocked simultaneously, spoil disposal is more thorough, and the utility model can also be used to handle low-temperature and low turbidity source water even carry out sewage disposal.
